biodegradable plastic from methane

this is very clever …. from the website

Mango Materials produces biodegradable plastics from waste biogas (methane) that are economically competitive with conventional oil-based plastics.

Methane of course is the second-most common greenhouse gas  and is a major contributor to global warming.

and in term of biodegradability….”The rate of degradation depends on the environment and thickness of the material. The Mango Materials product can break down in aerobic and anaerobic conditions and is expected to pass all relevant ASTM and other bio-related certification tests.”

A plastic that cuts methane and biodegrades. Well worth watching….

Straws Suck – just say no…

11181182_10153607820929653_743831970936423610_nThink refusing plastic straws is a pointless gesture? Saying no a ridiculous over reaction by the plastic free killjoys. Have a look at this gruesome video of a plastic straw being removed from a turtles snout and think again.

It is pretty distressing and some adult language is used to express the shock and shame
Please reconsider. Do you really need a plastic straw? They don’t all end up in the bin. Some end up in the sea. Because plastic doesn’t biodegrade they last for ever. They  will be there for a very long time and they can do real damage to wild life.

If you do need a straw why not get a reusable one. There are lots of options here.

If you really need a disposable straw, get a biodegradable one – they do exist – try this link..

Its not just straws and turtles, plastic trash is implicated in the maiming and death of hundreds of animals, birds and marine life. Check out the reports here.

Degradable, biodegradable or compostable

So most plastics are made from oil and most plastics do not biodegrade. See how and why here…

And yet you will find plastics described as

  • degradable
  • biodegradable
  • compostable

What do these terms actually mean when applied to plastic?

Remember that

  • Most traditional, oil-based plastics do not biodegrade.
  • Biodegradable products break down as the result of the actions of naturally occurring microorganisms, such as fungi or bacteria, over a time.
  • Plastic breaks, tears and cracks. It weathers and sunlight makes it brittle, It falls apart – it degrades – but only into smaller pieces of plastic.
  • Find out more about the lifecycle of plastic here.

Degradable Plastic

All plastic degrade – i.e. they fall apart into smaller pieces of plastic. BUT when a plastic is described as degradable it could just describe the falling part process  OR it could mean t a degradation initiator has been added to make it fall apart faster.

Degradation Initiators and Bio-Degradable Plastics

But suppose there was a way of making plastic biodegradable? The industry argue that they can do just that by means of chemical additives known as degradation initiators. Very basically, these additives break the long unnatural plastic polymers into shorter recognisable polymers that microbes can attack and digest – or biodegrade (N.B. lots more research need to be done on this. It is by no means proven).

Because the degradation initiators are biologically  based they are sometimes described as biodegradable. So some traditional plastic bags have been labelled biodegradable.

This is  at best confusing if not deliberately misleading. This  is not the same process as natural biodegrading. Unlike truly biodegradable products they don’t always break down into harmless substances and may leave behind a toxic residue.

More so as  there are some compostable plastics which are also described (correctly) as  biodegradable which do actually compost down into biomass.

Read more about degradation initiators here.

Compostable Biodegradable Plastics

Truly biodegradable plastics are compostable.

Biodegradable products break down through a naturally occurring microorganism into simple, stable compounds which can be absorbed into the ecosystem. To be classed compostable, items must biodegrade within a certain time (around the rate at which paper biodegrades) For a man-made product to be sold as compostable, it has to meet certain standards. One such is the European Norm EN13432.

Compostable Plastics  meet all of these criteria. You can find out more here.

Compostable Plastics Index

Plastic was the name given to early synthetic products such as cellophane,  that were derived from cellulose. These plastics  were biodegradable. Then they learnt how to make similar products from oil. Or rather from the bits of crude left over after they had finished making petrol. The same name was then given the oil derived product. But there were crucial differences. This new product was  made in a very different way and did NOT biodegrade.Since then yet more “plastics” have hit the market. Made from all kinds of things. Some from plant starch and some are certified compostable.

To conclude;
Currently, non- biodegradable, oil derived plastics are the most commonly used and so we tend to ascribe their qualities to all types of plastic.
In fact plastics can be made in a variety of ways from a variety of materials; shale gas, oil, plants even chicken feathers;
And different plastics have very different qualities. Some plastics do biodegrade and are certified compostable

Biodegradable, Compostable Plastics

Just to remind you:
What is biodegradable? Biodegradable products break down through a naturally occurring microorganism into simple, stable compounds which can be absorbed into the ecosystem. More about biodegrading here
What is compostable? To be classed compostable, items must biodegrade within a certain time (around the rate at which paper biodegrades), and the resulting biomass must be free of toxins, able to sustain plant life and be used as an organic fertilizer or soil additive.
For a man-made product to be sold as compostable, it has to meet certain standards. One such is the European Norm EN13432.

Home Or Industrial Compostable?

Composting can be done at home, by community or on a much larger scale by the council

Home Composting
Composting is usually done on a small scale and most people will be familiar with the concept of a backyard heap or garden compost where household waste is rotted down into garden mulch.

Composting Plastic At Home
While most agree that PLA plastic is indeed compostable, many say that it can only composted in large scale municipal schemes.
They are wrong. I have been composting plastics for years.

To be sure you are using a compostable plastic get one that has been certified compostable. Check out the logo.

Compostable Plastic Products

See a wide range HERE

Industrial composting
However large-scale schemes are becoming increasingly popular. In the UK communities band together to compost a whole street is worth of waste. Even city councils are getting in on the act.
These larger projects are sometimes called industrial composting

The difference is is that industrial composting is a lot hotter and can work more quickly.

Composting On A Larger Scale

Compostable Plastic Products

These compostable plastics, like oil derived, are extremely versatile.
They can be thin and flimsy which means they can be used to make

PLA Compostable Plastic Bags

And longer lasting products like phone cases

See a wide range of compostable products HERE

Compostable Plastics Types
Cellulose derived plastics such as Cellophane.
Starch based PLA plastics. They are certified compostable.
Polyhydroxyalkanoates or PHAs  are linear polyesters produced in nature by bacterial fermentation of ­sugar or lipids.
chicken feathers bioplastic.

 

A Note On Bioplastics
Most compostable plastics are also bioplastics. Bioplastics are made from natural materials such as corn starch.
However not all are compostable. For example ethane based plastics as used Coca-Cola’s PlantBottle which replaces 30 percent of the ethanol in their normal polyethylene terephthalate (PET) plastic bottle with 30 percent plant-derived ethanol. This means the bottle is still considered PET and can be recycled but is NOT biodegradable. Find out more here.

Other Plastics
There is research being done into developing a compostable, oil-derived plastic. Watch this space BUT don’t fall for the old *biodegradable plastic bag trick see below.

*Compostable versus biodegradable plastics
You might see some plastics labelled described as biodegradable. You could be forgiven for thinking that this is the same as compostable plastic. It is not. Some “biodegradable plastics” are oil derived plastics with a degrading initiator added to make them fall apart (degrade) more  quickly. Unlike compostable plastics they don’t always break down into harmless substances and may leave behind a toxic residue. Read more here

Stats on fibre production

Introduction to Fibres & Fabrics

Definitions

  • Fibres are short fine hairs.
  • Fibres can be can be natural, synthetic or chemically produced hybrid called regenerated fibres.
  • Fibres can be twisted or spun into longer thread or yarn.
  • Threads can be woven or knitted into fabric.

 

Natural Fibres

These are plant or animal derived and they biodegrade.

Coarse Fibres Are used for rope, string, sacking and industrial uses. They include

  • Abaca for rope,
  • coir from coconuts has a wide range of applications,
  • jute is used for sack cloth and
  • sisal for string.

Fibres used for finer fabrics and yarn include

  • Cotton used to make cotton
  • Flax is used to make linen. It is one of the strongest vegetable fibres. Other vegetable fibres include hemp and nettles.
  • Wool and other animal hair 
  • Silk strong and light weight.
  • Read more  HERE

Synthetic fibres

  • These are man-made from chemicals many of which are petroleum derived.
    Most do not biodegrade.
  • Acrylic, nylon and polyester  are the most common. They are made from oil and coal.
  • Read more HERE

Regenerated Fibres

  • The base material is cellulose that can be obtained from a range of sources including wood, paper, cotton fibre, or  bamboo. It is then converted through a chemical process into a fibre.

    Some it is claimed are biodegradable. Some are not.

    They usually go under the trade names such as 

    • Rayon
    • Bamboo Rayon
    • Viscose,
    • Modal
    • Tencel (lyocell)
    • Read more HERE

Mixed Fibre

Where different fibres are mixed together like a wool/ silk mix  popular for suits or natural and synthetic eg polycotton. 

Then there are other more specialist mixes  where natural fibres are mixed with elasticine added to make fabric stretchy.

 

Yarns, Threads and Ropes

Yarns and threads usually take the name from the fibre in which they are spun. They range from thin threads for sewing to thick ropes. 

Here are the ones we use.

 

Fabrics

Threads can be woven or knitted into fabric.

They may be named after then yarn type. So cotton can be the fibre the yarn or the fabric. They may be named after the trade name like Modal.

But fabrics can also be subdivided into a huge number of additional categories. For example cotton fabric can be described as denim, lawn or muslin.

Fabric may also be described by the technique used to make it. So jersey is a knitted fabric that could be made from cotton, silk or polyester.

Clothing

Clothes can now be made out of woven/knitted fabrics or knitted yarn.

Fibre Production

fibre pie chart

2013 figures

Global 2013 fibre production estimated at 85.5 million tons

• Global 2013 synthetic fibre production estimated at 55.8 million tons (i.e. excluding cotton, cellulosics and wool)

Natural Fibres
Cotton 25 million tons
wool production is around 2.1 million tonnes.
Silk 150 000 tonnes in 2006
Linen 147 000 tonnes of flax fibre 2007,
Alpaca 6 500 tonnes
Cashmere” after scouring and dehairing 6 500 tonnes
Mohair is estimated at around 5 000 tonnes a year, down from a high of 25 000 tonnes in the 1990s,
Angora is estimated at 2 500 to 3 000 tonnes
2009 figures  only – google let me down!

Carbon footprint

A study done by the Stockholm Environment Institute on behalf of the BioRegional Development Group  concludes that the energy used (and therefore the CO2 emitted) to create 1 ton of spun fiber is much higher for synthetics than for hemp or cotton:

Corals & Micro Plastics

Corals such as those found on the Great Barrier Reef are at risk from the estimated 5tn pieces of plastic in the world’s oceans because researchers have discovered they digest tiny fragments of plastic at a significant rate.

A study led by the ARC centre of excellence for coral reef studies at James Cook University found that corals consumed “microplastics” – plastics measuring under 5mm – about the same rate as their normal food.

Charity Shop Issues

A reason not to buy in charity shops can be found on the Woven website about the second hand clothing trade in AFRICA

The following has been taken from the website

Africa is the fastest growing population center in the world. It currently has 1.1 billion people. That numbers nearly quadruples to 4.1billion by 2100.
The continent has the highest unemployment rates in the world in spite of having six of the worlds fastest growing economies.

“Probably 90% of the clothing people are buying in the whole country are second-hand clothes.” Sylvia Owori, Ugandan fashion designer.

SECOND-HAND CLOTHES IN AFRICA
Everyday before sunrise vendors line up to get first dibs on the huge pallets of compressed clothes as they come off trucks. They have absolutely no idea what’s inside.

BUYING THEMSELVES POOR
How much do you think someone living in Africa (the poorest continent on Earth) pays for a pair of second-hand jeans?
Places where over 80% of people make less than $2 a day (the UN global poverty benchmark). $1? $2? $3, more than a days wage? Guess again:
$5 to $7. Over two or three times what they earn in a day. But wait, there’s more.
All but a fraction of that money leaves the continent. Why? Because vendors purchase these bundles from international “clothing recyclers” that buy 97% the clothes you and I donate to charities like Goodwill, The Salvation Army and The Cancer Society. Vendors in the developing world pay up to a 1,000% markup for bundled clothes, lining these international companies pockets with huge profits–$3 billion a year huge–and none of that money supports the causes we thought we were.

This isn’t to blame the charities we donated to. In all honesty they do their best and if they could sell more donated clothes locally they would–they’d make more money that way. The truth is people don’t want to buy second-hand clothes in the developed world and charities that accept clothes have no other choice but to sell clothes they can’t sell locally to clothing recyclers.]

THE POOR GET POORER

The impact is devastating:  50% loss in jobs and a 40% decline in industry over two decades.
Textile and clothing employment along with other support work offer valuable entry level jobs in fledgling economies. Ghana and Nigeria are among the hardest hit losing 80% and over 95% of their textile employment respectively.

TEXTILES: END OF LIFE IS JUST AS IMPORTANT AS MANUFACTURING

Most people understand what’s happening on the production side of the textile industry (i.e. sweatshops, etc) but few realize what’s happens to their clothes at the end of life when they donate them and they think they are doing some good.
Before I started looking into this I thought that clothes I donated were helping people in my local community by providing affordable clothes to less fortunate families. I was shocked to learn that only 3% of the clothes donated are ever resold locally. That’s three items for every 100 donated.
I was even more shocked to hear that the nonprofit I donate my clothes to only earns between $0.10 and $0.25 per pound. That’s about $0.20 to $0.50 for a pair of jeans.

Whats that dot mean?

The Green Dot is a symbol used on packaging in many European countries.

It looks like a recycling logo but is not.

It is a trademark.

It is not always green. Sometimes it is black and white!

In the UK but has no specific meaning for UK consumers.

In Europe howeve it indicates that a packaging producer has paid the have a proportion of their packaging collected and recycled.

They have to. The European “Packaging and Packaging Waste Directive – 94/62/EC”  This applies to all companies whose products use packaging. It states that manufacturers have to collect any recyclable packaging they use.

Obviously most do not do this. Instead they pay a company to do it for them. They can then display the green dot on their packaging.

Frequently asked questions about the Green Dot® program.

Which companies need to comply with the Packaging Waste Directive?
All companies need to comply with the Directive if their products include nearly any type of packaging.

Can I come up with my own packaging recovery plan and avoid joining Green Dot®?
Yes, you can present your own plan for packaging recovery. This may make sense if you are very low volume producer with very few customers.

Am I required to join the Green Dot® scheme?
No. You are not required to join a program such as Green Dot®. However, the Packaging Directive requires manufacturers to recover their own packaging. Most companies find this impractical and participating in the Green Dot® Program is one way to meet these requirements.

You can find this very useful Q&A post here

To conclude

  • A licence fee is paid by manufactorers towards the cost of collection and recycling.
  • The amount paid depends on the material used in packaging (e.g. paper, plastic, metal, wood, cardboard).
  • Different countries pay diferent amounts for joining the the scheme.
  • Fees take into account the cost of collection, sorting and recycling methods.
  • A reduction in packaging means a reduction in the liscence fee.
  • Once the fee is paid the company can then display the green dot on their packaging and consumers will know that the manufacturer contributes to the cost of recovery and recycling.

We do not use this system in the UK. The Green Dot is not used as a compliance mark in the UK, but it is still a trademark. Anyone who produces packaging with a Green Dot, which is then sold in the UK, must pay a UK licence fee through Valpak Ltd.

Biodegradation of polyethylene

Polyethylene

This is the most common plastic. The annual global production of polythene is approximately 80 million tonnes.

Evidence of Polyethylene Biodegradation by Bacterial Strains from the Guts of Plastic-Eating Waxworms
Environ. Sci. Technol., 2014, 48 (23), pp 13776–13784
DOI: 10.1021/es504038a

Abstract
Polyethylene (PE) has been considered nonbiodegradable for decades. Although the biodegradation of PE by bacterial cultures has been occasionally described, valid evidence of PE biodegradation has remained limited in the literature. We found that waxworms, or Indian mealmoths (the larvae of Plodia interpunctella), were capable of chewing and eating PE films. Two bacterial strains capable of degrading PE were isolated from this worm’s gut, Enterobacter asburiae YT1 and Bacillus sp. YP1. Over a 28-day incubation period of the two strains on PE films, viable biofilms formed, and the PE films’ hydrophobicity decreased. Obvious damage, including pits and cavities (0.3–0.4 μm in depth), was observed on the surfaces of the PE films using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The formation of carbonyl groups was verified using X-ray photoelectron spectroscopy (XPS) and microattenuated total reflectance/Fourier transform infrared (micro-ATR/FTIR) imaging microscope. Suspension cultures of YT1 and YP1 (108 cells/mL) were able to degrade approximately 6.1 ± 0.3% and 10.7 ± 0.2% of the PE films (100 mg), respectively, over a 60-day incubation period. The molecular weights of the residual PE films were lower, and the release of 12 water-soluble daughter products was also detected. The results demonstrated the presence of PE-degrading bacteria in the guts of waxworms and provided promising evidence for the biodegradation of PE in the environment.

Polyurethane

Polyurethane is a general term used for a class of polymers derived from the condensation of polyisocyanates and polyalcohols.

Polyeurothenes are are petrochemical-based derived polymer and (man) made like all the other synthetic polymers featured in this blog.

Polyurethane is made by reacting polyols and diisocyanates,

Polyols and diisocyanates are derived from crude oil and removed during the refining process just like gasoline.

Polyurethane foam can be flexible or rigid. Each form of polyurethane has many uses.

Most polyurethanes do not melt when heated but there are some (thermoplastic polyurethanes) that do.

Polyurethane formulations cover an extremely wide range of stiffness, hardness, and densities. These materials include:

Low-density flexible foam used in upholstery, bedding, and automotive and truck seating
Low-density rigid foam used for thermal insulation and RTM cores
Soft solid elastomers used for gel pads and print rollers
Low density elastomers used in footwear
Hard solid plastics used as electronic instrument bezels and structural parts
Flexible plastics used as straps and bands
lining the cups of brassieres.

Wikkipedia

Carbon dioxide is used as a blowing agent to create the soft, comfortable feel of a mattress or sofa. The more blowing agent is used, the softer the resulting foam.
In rigid foams, a gas such as pentane is “trapped” in the closed cells of the foam, optimising its insulation capacity.
Rollerblade wheels, on the other hand, do not require a blowing agent and instead have a dense and hardwearing consistency.

Is polyeurothene a plastic?
this answer from Quora is a useful read

There is thermoset and thermoplastic polyurethane polymers. Both can be considered as “plastics”.

Actually “Plastics” is more a shortcut / a general public word. It refer to the fact that most of these materials have a high plasticity (ability to be permanently deform without breaking) under certain conditions. Not to a chemical composition. Specialists prefer to speak of polymers and composites.

In general language, most of common polymers compounds that can be injected/extruded are generally referred as plastics.

When it comes to Carbone/glass fiber reinforced Polyamide or to the Aramids family (including Kevlar and Grivory brands), you will rarely see the word “plastic” used because it would be devaluating for these high performance composites. Yet actually these materials can be extruded or injected quite the same way as generic plastics like PE or PP. So that these are fitting perfectly in the “plastics” category.
So that it is correct to say that thermoplastic and thermoset polymers are plastics. Including PU.

Polyurethanes are polymers. Polymers are best thought of as chains of three-dimensional structures made up of long, repeating smaller units called monomers. These monomers contain carbon, hydrogen, oxygen and nitrogen. To form the chains, the smaller links are “polymerised” or hooked together.

There are thousands of naturally occurring and man-made polymers. The first man-made polymer to be produced was Bakelite in 1909. Rayon, the first man-made fibre polymer, was developed in 1911. Other well known polymers include nylon, silicon, polyethylene, polypropylene and polystyrene.

Read more.

Common polyurethane applications include:
Building insulation
Refrigerators and freezers
Furniture and bedding
Footwear
Automotive
Coatings and adhesives
Other applications read more here.

Polyurethane is the most common solvent used in modern varnishes.

Despite its xenobiotic origins, polyurethane has been found to be susceptible to biodegradation by naturally occurring microorganisms. Microbial degradation of polyurethanes is dependent on the many properties of the polymer such as molecular orientation, crystallinity, cross-linking and chemical groups present in the molecular chains which determine the accessibility to degrading-enzyme systems. Esterase activity (both membrane-bound and extracellular) has been noted in microbes which allow them to utilize polyurethane. Microbial degradation of polyester polyurethane is hypothosized to be mainly due to the hydrolysis of ester bonds by these esterase enzymes.

Isocyanates are compounds containing the isocyanate group (-NCO). They react with compounds containing alcohol (hydroxyl) groups to produce polyurethane polymers, which are components of polyurethane foams, thermoplastic elastomers, spandex fibers, and polyurethane paints. Isocyanates are the raw materials that make up all polyurethane products. Jobs that may involve exposure to isocyanates include painting, foam-blowing, and the manufacture of many Polyurethane products, such as chemicals, polyurethane foam, insulation materials, surface coatings, car seats, furniture, foam mattresses, under-carpet padding, packaging materials, shoes, laminated fabrics, polyurethane rubber, and adhesives, and during the thermal degradation of polyurethane products.

Health effects of isocyanate exposure include irritation of skin and mucous membranes, chest tightness, and difficult breathing. Isocyanates include compounds classified as potential human carcinogens and known to cause cancer in animals. The main effects of hazardous exposures are occupational asthma and other lung problems, as well as irritation of the eyes, nose, throat, and skin. https://www.osha.gov/SLTC/isocyanates/index.html

Plastic in the Sea – Studies

Latest reports and news stories about plastic in the sea can be found here, (reports and statistics about other plastic related issues can be found here)

Thanks to Fabiano of www.globalgarbage.org for keeping us well informed.

Try schnews for the nasty nurdles

billions of tiny plastic pellets, called nurdles – the raw materials for the plastic industry – are lost or spilled every year, many ending up in the sea. These act like chemical sponges, soaking up other toxic man-made chemicals, all artificial pollutants (for toxicity think DDT pesticide etc), concentrating them up to a million times more than in normal sea water.

Chris Wilcox, Nicholas J. Mallos, George H. Leonard, Alba Rodriguez, Britta Denise Hardesty, Using expert elicitation to estimate the impacts of plastic pollution on marine wildlife, Marine Policy, Volume 65, March 2016, Pages 107-114, ISSN 0308-597X,http://dx.doi.org/10.1016/j.marpol.2015.10.014.
(http://www.sciencedirect.com/science/article/pii/S0308597X15002985)
Abstract: Marine litter is a growing environmental concern. With the rapid increase in global plastics production and the resulting large volume of litter that enters the marine environment, determining the consequences of this debris on marine fauna and ocean health has now become a critical environmental priority, particularly for threatened and endangered species. However, there are limited data about the impacts of debris on marine species from which to draw conclusions about the population consequences of anthropogenic debris. To address this knowledge gap, information was elicited from experts on the ecological threat (both severity and specificity) of entanglement, ingestion and chemical contamination for three major marine taxa: seabirds, sea turtles and marine mammals. The threat assessment focused on the most common types of litter that are found along the world’s coastlines, based on data gathered during three decades of international coastal clean-up efforts. Fishing related gear, balloons and plastic bags were estimated to pose the greatest entanglement risk to marine fauna. In contrast, experts identified a broader suite of items of concern for ingestion, with plastic bags and plastic utensils ranked as the greatest threats. Entanglement and ingestion affected a similar range of taxa, although entanglement was rated as slightly worse because it is more likely to be lethal. Contamination was scored the lowest in terms of impact, affecting a smaller portion of the taxa and being rated as having solely non-lethal impacts. This work points towards a number of opportunities both for policy-based and consumer-driven changes in plastics use that could have demonstrable affects for a range of ecologically important taxa that serve as indicators of marine ecosystem health.

Abstract: The rise of plastics since the mid-20th century, both as a material element of modern life and as a growing environmental pollutant, has been widely described. Their distribution in both the terrestrial and marine realms suggests that they are a key geological indicator of the Anthropocene, as a distinctive stratal component. Most immediately evident in terrestrial deposits, they are clearly becoming widespread in marine sedimentary deposits in both shallow- and deep-water settings. They are abundant and widespread as macroscopic fragments and virtually ubiquitous as microplastic particles; these are dispersed by both physical and biological processes, not least via the food chain and the ‘faecal express’ route from surface to sea floor. Plastics are already widely dispersed in sedimentary deposits, and their amount seems likely to grow several-fold over the next few decades. They will continue to be input into the sedimentary cycle over coming millennia as temporary stores – landfill sites – are eroded. Plastics already enable fine time resolution within Anthropocene deposits via the development of their different types and via the artefacts (‘technofossils’) they are moulded into, and many of these may have long-term preservation potential when buried in strata.

Abstract: Plastic debris on six beaches near the Nakdong River Estuary, South Korea, was sampled in May and September 2012 and classified into three size classes, large microplastics (1–5 mm), mesoplastics (5–25mm), and macroplastics (>25 mm). The relationships among the abundances of the size classes were then examined. The abundances of each size category in May (before rainy season) and in September (after rainy season) were 8205 and 27,606 particles/m2 for large microplastics, 238 and 237 particles/m2 for mesoplastics, and 0.97 and 1.03 particles/m2 for macroplastics, respectively. Styrofoam was the most abundant item both in microplastic and mesoplastic debris, while intact plastics were most common in macroplastic debris. The abundances of meso- and micro-plastics were the most strongly correlated. There was a higher correlation between the abundances of macro- and meso-plastics than between macro- and micro-plastics.

Abstract: Studies concerning marine litter have received great attention over the last several years by the scientific community mainly due to their ecological and economic impacts in marine ecosystems, from coastal waters to the deep ocean seafloor. The distribution, type and abundance of marine litter in Ormonde and Gettysburg, the two seamounts of Gorringe Bank, were analyzed from photo and video imagery obtained during ROV-based surveys carried out at 60–3015 m depths during the E/V Nautilus cruise NA017. Located approximately 125 nm southwest of Portugal, Gorringe Bank lays at the crossroad between the Atlantic and the Mediterranean and is therefore characterized by an intense maritime traffic and fishing activities. The high frequency of lost or discarded fishing gear, such as cables, longlines and nets, observed on Gorringe Bank suggests an origin mostly from fishing activities, with a clear turnover in the type of litter (mostly metal, glass and to a much lesser extent, plastic) with increasing depth. Litter was more abundant at the summit of Gorringe Bank (ca. 4 items·km− 1), decreasing to less than 1 item·km− 1 at the flanks and to ca. 2 items·km− 1 at greater depths. Nevertheless, litter abundance appeared to be lower than in continental margin areas. The results presented herein are a contribution to support further actions for the conservation of vulnerable habitats on Gorringe Bank so that they can continue contributing to fishery productivity in the surrounding region.

“World’s Plastics Associations Renew Commitments to Improve Sustainability”

Manila (December 12, 2014) – At the 25th annual Global Meeting on Plastics and Sustainability, held in Manila, Philippines (Dec. 8 – 10), executives from the world’s leading plastics associations met to discuss and advance sustainability, and to promote solutions to plastic waste management and marine debris. At the meeting, delegates noted strong progress and growth in activities undertaken as part of the Declaration of the Global Plastics Associations for Solutions on Marine Litter. Under that program, 60 associations from more than 30 countries have launched 185 separate projects to combat plastic marine debris.

At the meeting, participants also discussed strategies to address sustainability by improving the collection, recycling and recovery of energy from used plastics. Delegates heard from Doug Woodring of the NGO Ocean Recovery Alliance, who challenged the industry to work with other stakeholders and to deploy new technologies to better understand where litter is entering our rivers and waterways.

In addition to leading Philippine companies, meeting participants included plastics associations from the Philippines, Malaysia, Thailand, Japan, Brazil, the Gulf, Europe, South Africa, and the United States, who analyzed current projects to prevent litter and increase recycling of plastic.

Scientists warn nearly 270,000 tonnes of plastic may be floating in world’s oceans

Stephanie Smail reported this story on Thursday, December 11, 2014 18:36:00

MARK COLVIN: It’s floating on the surface, bobbing just under the waves, strangling seabirds and killing fish. It’s plastic in the ocean, and a new study says there’s nearly 270,000 tonnes of it.

International scientists have counted and weighed tiny pieces of plastic, and bigger pieces like plastic bottles and six-pack holders, for the past six years.

Their research has found plastic pollution isn’t just a problem in the well-known garbage patches in remote areas. It’s also lurking close to coastlines, as Stephanie Smail reports.

No part of the ocean untouched by plastic rubbish

BY CHRISTOPHER DOYLE

ABC Environment 11 DEC 2014

A new study has found that plastic rubbish reaches into almost every corner of the ocean.

VIRTUALLY NO PART of the ocean surface remains untouched by plastic debris, a team of international scientists has found.

Nearly 269,000 tonnes of plastic debris is floating on the surface of the world’s oceans, with some of it occurring in some of the most remote regions of the planet, the scientists report today in the open-access journal PLoS One.

“There are areas of the ocean that have very little plastic, but I don’t think you will find plastic-free seas anywhere in the world today,” said Dr Marcus Eriksen, lead author of the study and Director of Research for the 5 Gyres Institute.

America’s Plastics Makers Support Calls to Address Litter in World’s Oceans

WASHINGTON (December 10, 2014) – The Five Gyres Institute today released a study that estimates the quantities of plastics in the world’s oceans (“Plastic Pollution in the World’s Oceans: More than 5 Trillion Plastic Pieces Weighing over 250,000 Tons Afloat at Sea”).

The American Chemistry Council (ACC) issued the following statement:

“America’s plastics makers wholeheartedly agree that littered plastics of any kind do not belong in the marine environment. Every day, plastics contribute to sustainability by enabling us to reduce, reuse, recycle, and recover more of the resources that we rely on—and by helping to lower energy use and greenhouse gas emissions. Even after plastics have fulfilled their initial purpose, these materials should be treated as valuable resources and recycled whenever possible or recovered for their energy value when they cannot.

“Recent multi-stakeholder efforts to develop solutions for marine litter—including a brochure (2014) produced by the Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection (GESAMP, an advisory group to the United Nations) and the Honolulu Strategy (2011)—have highlighted the importance of using modern, integrated waste management infrastructure and practices to combat marine litter throughout the globe. This includes recycling and energy recovery, and the American Chemistry Council’s Plastics Division and its member companies support these recommendations.

Good job, humans: The oceans now contain 5 trillion pieces of floating plastic

By Chris Mooney December 10

A major new study of the world’s oceans has reached a shocking conclusion: Thanks to humans, there are now over 5 trillion pieces of plastic, weighing more than 250,000 tons, floating in water around the world.

With a global population of about 7.2 billion, that’s nearly 700 pieces per person.

The study, published in the journal PLOS One by Marcus Eriksen of the Five Gyres Institute in Los Angeles and a large group of colleagues, is based on data from 24 separate ocean expeditions, conducted between 2007 and 2013, to sample plastic pollution. Plastic was either observed from boats, or hauled up from the ocean by nets, in 1,571 locations. The data were then used to run an ocean model to simulate the amount and distribution of plastic debris.

The result not only yielded the estimate of over 5 trillion pieces of plastic in the global ocean — it also cast light on how plastic changes within the ocean (breaking down into smaller pieces) and circulates around the globe. Pieces between 1 millimeter and 4.75 millimeters in size were by far the most prevalent class of plastic in the ocean. However, by weight, really large pieces of plastic, greater than 200 millimeters in size, were the most significant.

Study Gauges Plastic Levels in Oceans

By JOHN SCHWARTZ DEC. 10, 2014

It is no secret that the world’s oceans are swimming with plastic debris — the first floating masses of trash were discovered in the 1990s. But researchers are starting to get a better sense of the size and scope of the problem.

A study published Wednesday in the journal PLOS One estimated that 5.25 trillion pieces of plastic, large and small, weighing 269,000 tons, could be found throughout the world’s oceans, even in the most remote reaches.

The ships conducting the research traveled the seas collecting small bits of plastic with nets and estimated worldwide figures from their samples using computer models. The largest source of plastic by weight comes from discarded fishing nets and buoys, said Marcus Eriksen, the leader of the effort and co-founder of the 5 Gyres Institute, a nonprofit group that combines scientific research with antipollution activism.

Full scale of plastic in the world’s oceans revealed for first time

Over five trillion pieces of plastic are floating in our oceans says most comprehensive study to date on plastic pollution around the world

Wednesday 10 December 2014 19.00 GMT

More than five trillion pieces of plastic, collectively weighing nearly 269,000 tonnes, are floating in the world’s oceans, causing damage throughout the food chain, new research has found.

Data collected by scientists from the US, France, Chile, Australia and New Zealand suggests a minimum of 5.25tn plastic particles in the oceans, most of them “micro plastics” measuring less than 5mm.

The volume of plastic pieces, largely deriving from products such as food and drink packaging and clothing, was calculated from data taken from 24 expeditions over a six-year period to 2013. The research, published in the journal PLOS One, is the first study to look at plastics of all sizes in the world’s oceans.

Large pieces of plastic can strangle animals such as seals, while smaller pieces are ingested by fish and then fed up the food chain, all the way to humans.

Environmentalists Go to Battle Over Face Wash

Katy Steinmetz @katysteinmetz
Dec. 10, 2014

Environmentalists are hoping a landmark report about how much plastic is in the world’s oceans will help get bans on small plastics passed

Face washes claiming to be “blackhead erasers” or “superfruit scrubs” may seem appealing for scrubbing your way to a fresh new face, but some of them also contain an ingredient that environmental advocates and lawmakers are trying to ban. Tiny, round bits of plastic known as microbeads, no bigger than a grain of couscous, may pose hazards in the natural world.

These little orbs, introduced to replace harsher exfoliants like pumice, are so small that after they’re washed down the sink or tub, they sneak through sifters at water treatment plants and end up in the ocean and other bodies of water. Once in the ocean, researchers have found, these plastics act like sponges for toxins, and can be accidentally ingested by fish, thus ending up in the food chain.

Several states considered bills to ban microbeads last session, but only Illinois passed a law, becoming the first state to do so. Now lawmakers in at least three states are gearing up for another go in 2015.

Autopsy finds plastic bag in dolphin’s stomach after failed rescue

By Nonee Walsh
Posted 28 Nov 2014, 7:34am

A dolphin rescued off Sydney’s northern beaches earlier this week has been euthanased after becoming stranded for a second time.

It took six men to refloat the three-metre Risso’s dolphin after they found it in trouble on Curl Curl Beach on Monday.

The mature female dolphin went back out to sea but became stranded again at Kurnell, in Sydney’s south, on Tuesday evening.

An autopsy performed at Taronga Zoo revealed a plastic bag was blocking its stomach, Organisation for the Rescue and Research of Cetaceans in Australia (ORRCA) president Ronnie Ling said.

 

Microfibres

We met him earlier in November picking up plastic micro fibers on the beach. Now he reveals more about himself and his projects here….

Benign By Design’s unique data-driven process propels the textile industry toward cost effective fabrics that emit fewer and less toxic fibers.

THE PROBLEM

Clothing fibers are the most abundant form of waste material that we find in habitats worldwide, and the problem is worsening. Ingested and inhaled fibers carry toxic materials and a third of the food we eat is contaminated with this material. In the textile industry, fabrics are generally selected based upon aesthetics, durability, cost, green chemistry and carbon footprints. Still, critical information on their environmental and health impacts is not considered because until now much of the scientific research is unavailable. This has led to the use of unsustainable and hazardous fibers in apparel.

THE INNOVATION

Benign by Design disrupts the current unsustainable pattern by showing companies exactly how textile wear leads to fiber pollution and ways to control their emissions. They developed a trade-off analysis system that rigorously and scientifically selects the most cost effective material with the smallest impact; fabrics that emit fewer fibers and less toxic fibers. The interdisciplinary team of leaders in ecology, Life Cycle Assessment, toxicology, engineering, chemistry, forensics, and ecosystem management provides cutting-edge research to reduce environmental and health impacts of fabrics, including a novel method of fiber quantification (³ 1 µm) in wastewater and animal tissues.

 “Our program will lead to cost-effective fabrics that emit fewer and less toxic fibers via novel research on how fabrics compare throughout their life cycle.” – Dr. Mark Anthony Browne, National Center for Ecological Analysis & Synthesis (NCEAS), University of California Santa Barbara

Stage of Innovation: Concept

THE VISION

Tracing emissions and impacts of fibers over their life cycle will guide sustainable design that builds upon established indices and tools (e.g. Nike’s Apparel Environmental Design tool) currently lacking such data. NCEAS pioneered open-data ecosystems (e.g. DataOne) to enable sharing, collaboration, contribution and unlimited accessibility to environmental data. Using this platform, and connections within the Sustainable Apparel Coalition and the American Association of Textile Chemists & Colorists, they will find early adopters, and then leverage a case study to achieve certification through the EPA’s Design for Environment Program.

“Our product empowers consumers to make informed choices, enabling them, for the first time, to purchase less hazardous fabrics that shed fewer potentially toxic fibers and chemicals throughout their life cycle.” – Dr. Mark Anthony Browne, National Center for Ecological Analysis & Synthesis (NCEAS), University of California Santa Barbara
