Weee / Electronic Waste

by Posted in 2.1 reports, stats and studies Tagged ,
 Between now and the end of 2020, WRAP estimates that electronic products purchased in the UK will total around 10 million tonnes. A quarter of this will comprise of IT equipment, consumer electronics and display screens. This 10 million tonnes will include precious metals, such as 20 tonnes of gold, 400 tonnes of silver and 7 tonnes of Platinum Group Metals. These have a total estimated market value of £1.5 billion [Dec 13].Waste on line

According to DEFRA figures, white goods make up 5% of household waste. 7 WEEE analysis shows that the average person will consume 3.3 tonnes of electronic waste in their lifetime, or on average around 0.016 tonnes (16 kg) per year. http://www.weeeman.org/html/impact/couple.html

Most of the components of electronic waste are recyclable, a fridge may contain as much as 95% recoverable material, whereas 96% of an old television could be made into new televisions.  do the green thing.

Wee waste has to be specially disposed of….

The directors of Warrington-based Daniels Recycling, who pleaded guilty last week to illegally exporting electrical waste to West Africa, have criticised the Environment Agency for its handling of the case.

Daniels Recycling Ltd is run by married couple Mark Daniels, 51, and Lynn Gallop, 52. At Warrington Crown Court last week, the pair pleaded guilty to illegally exporting 187 tonnes of waste electrical and electronic equipment (WEEE) to Nigeria, Ghana, the Ivory Coast, Tanzania, Gambia and Togo between 2011 and 2015. They were ordered by the court to pay fines and costs totalling £130,000.

leaching into your food………

The researchers bought more than 450 plastic items from stores including Walmart and Whole Foods. They chose products designed to come in contact with food — things like baby bottles, deli packaging and flexible bags, says George Bittner, one of the study’s authors and a professor of biology at the University of Texas, Austin.

Then CertiChem, a testing company founded by Bittner, chopped up pieces of each product and soaked them in either saltwater or alcohol to see what came out.

The testing showed that more than 70 percent of the products released chemicals that acted like estrogen. And that was before they exposed the stuff to real-world conditions: simulated sunlight, dishwashing and microwaving,

Could sterilising plastic bottles in hot water do more harm than good? Scott Belcher and his colleagues at the University of Cincinnati in Ohio have found that polycarbonate plastic bottles release up to 55 times more bisphenol A (BPA) after they’ve been washed in boiling water.

BPA is found in many plastic food and drink containers and has been linked to breast and prostate cancer. Because they are often reused, Belcher wanted to test whether old containers leached BPA into their contents faster than new ones. His team filled new and used polycarbonate plastic bottles with water and kept them at room temperature for a week. They found that the rate of BPA release into the water by new and used bottles was an average of 0.49 nanograms an hour.

But when the team mimicked sterilisation by filling the bottles with boiling water and leaving them to cool, they found that the average rate of BPA release jumped to 18.67 nanograms per hour. This continued even after the bottles had cooled and been rinsed out (Toxicology Letters, DOI: 10.1016/j.toxlet.2007.11.001).

While the levels of released BPA fall within safe limits as currently defined by the European Food Safety Authority, Belcher suggests switching to bottles made of high-density polyethylene as a precaution.

“As staunch supporters of the anti-BPA campaign we were very pleased to see coverage in the British media last Friday of a new report linking BPA to breast cancer. The Daily Mail and the BBC both featured articles about Professor Anna Soto, an expert in cancer development ar the University of Ulster, who has recently carried out research on BPA . She is warning that BPA can trigger toxins which lead to cancer after discovering that foetal and neonatal exposure to the chemical increases the likelihood of development of malignant tumours later in life.

Interesting article here

Teeguarden says that pM levels of BPA ought not to be a concern for us. This is because if the hypothesis that BPA causes harm by mimicking oestrogen is correct, then the dose of the chemical your average person receives everyday is 100 to 10,000 times lower than those needed to activate the hormone receptors. He also makes the point that the term ‘low dose’ has become somewhat debased in the BPA literature. When he looked at 130 animal studies using that term, the vast majority used BPA levels many times higher than a person would ever encounter in their diet. He says that this is more than just an academic point as it has contributed to confusion among toxicologists, epidemiologists and the general public.

Abstract: Sources, pathways and reservoirs of microplastics, plastic particles smaller than 5 mm, remain poorly documented in an urban context. While some studies pointed out wastewater treatment plants as a potential pathway of microplastics, none have focused on the atmospheric compartment. In this work, the atmospheric fallout of microplastics was investigated in two different urban and sub-urban sites. Microplastics were collected continuously with a stainless steel funnel. Samples were then filtered and observed with a stereomicroscope. Fibers accounted for almost all the microplastics collected. An atmospheric fallout between 2 and 355 particles/m2/day was highlighted. Registered fluxes were systematically higher at the urban than at the sub-urban site. Chemical characterization allowed to estimate at 29% the proportion of these fibers being all synthetic (made with petrochemicals), or a mixture of natural and synthetic material. Extrapolation using weight and volume estimates of the collected fibers, allowed a rough estimation showing that between 3 and 10 tons of fibers are deposited by atmospheric fallout at the scale of the Parisian agglomeration every year (2500 km2). These results could serve the scientific community working on the different sources of microplastic in both continental and marine environments.

Abstract: The impact that microplastics have on baleen whales is a question that remains largely unexplored. This study examined the interaction between free-ranging fin whales (Balaenoptera physalus) and microplastics by comparing populations living in two semi-enclosed basins, the Mediterranean Sea and the Sea of Cortez (Gulf of California, Mexico). The results indicate that a considerable abundance of microplastics and plastic additives exists in the neustonic samples from Pelagos Sanctuary of the Mediterranean Sea, and that pelagic areas containing high densities of microplastics overlap with whale feeding grounds, suggesting that whales are exposed to microplastics during foraging; this was confirmed by the observation of a temporal increase in toxicological stress in whales. Given the abundance of microplastics in the Mediterranean environment, along with the high concentrations of Persistent Bioaccumulative and Toxic (PBT) chemicals, plastic additives and biomarker responses detected in the biopsies of Mediterranean whales as compared to those in whales inhabiting the Sea of Cortez, we believe that exposure to microplastics because of direct ingestion and consumption of contaminated prey poses a major threat to the health of fin whales in the Mediterranean Sea.

Abstract: The release of plastics into the environment has been identified as an important issue for some time. Recent publications have suggested that the degradation of plastic materials will result in the release of nano-sized plastic particles to the environment. Nanoparticle tracking analysis was applied to characterise the formation of nanoplastics during the degradation of a polystyrene (PS) disposable coffee cup lid. The results clearly show an increase in the formation of nanoplastics over time. After 56 days’ exposure the concentration of nanoplastics in the PS sample was 1.26 × 108 particles/ml (average particles size 224 nm) compared to 0.41 × 108 particles/ml in the control.

Abstract: Concentrations of microplastics within two geographically distinct urban locations within Burrard Inlet, British Columbia (BC), and the influence of facial scrub microbeads on lead and cadmium sorption within intertidal sediments were determined. Bulk intertidal sediment sampled from Cates Park (CP) located within the protected part of the inlet contained greater concentrations of microplastics (5560/kg wet sediment) as compared to Horseshoe Bay (HSB) (3120/kg wet sediment) located on the exposed open part of the inlet. Of the recovered microplastics ca. 75% were characterized as microbeads. Laboratory controlled microcosm experiments in which microbeads separated from a commercial facial scrub were added to bulk sediments collected from CP at ambient and 10-fold ambient (high) concentrations indicated that the microbeads acted as sorption sites. At ambient concentrations, less lead was recovered from pore water and surface water of treatment as compared to control microcosms. At high concentrations, the microbeads acted as a contaminant source to the microcosms, notably cadmium. Sorption of lead to microbeads has important implications for the potential role of microplastics, in this case microbeads acting as a yet quantified link in aquatic food webs.

Abstract: Knowledge on multi-stressors effects required for environmental and human risk assessments is still limited. This study investigated the combined effects of gold nanoparticles (Au-NP), microplastics (MP) and temperature increase on Pomatoschistus microps, an important prey for several higher level predators, including some species edible to humans. Four null hypotheses were tested: H01: P. microps juveniles do not take up Au-NP through the water; H02: Au-NP (ppb range) are not toxic to juveniles; H03: the presence of MP do not influence the effects of Au-NP on juveniles; H04: temperature increase (20–25 °C) does not change the effects of the tested chemicals on juveniles. Wild juveniles were acclimated to laboratory conditions. Then, they were exposed to Au-NP (≈5 nm diameter) and MP (polyethylene spheres, 1–5 μm diameter), alone and in mixture, at 20 °C and 25 °C, in semi-static conditions. After 96 h of exposure to Au-NP, fish had gold in their body (0.129–0.546 μg/g w.w.) leading to H01 refusal. Exposure to Au-NP alone caused a predatory performance decrease (≈−39%, p < 0.05) leading to H02 refusal. MP did not change the Au-NP toxicity leading to H03 acceptance. Temperature rise significantly increased the concentration of gold in fish exposed to Au-NP (≈2.3 fold), and interacted with chemical effects (e.g. glutathione S-transferases activity) leading to H04 refusal. Thus, the results of this study highlight the importance of further investigating the effects of multi-stressors on marine fish, particularly the effects of temperature on the uptake, biotransformation, elimination and effects of nanoparticles and microplastics, either alone or in mixture. This knowledge is most important to improve the basis for environmental and human risk assessments of these environmental contaminants of high concern.

Abstract: The unbridled increase in plastic pollution of the world’s oceans raises concerns about potential effects these materials may have on microalgae, which are primary producers at the basis of the food chain and a major global source of oxygen. Our current understanding about the potential modes and mechanisms of toxic action that plastic particles exert on microalgae is extremely limited. How effects might vary with particle size and the physico-chemical properties of the specific plastic material in question are equally unelucidated, but may hold clues to how toxicity, if observed, is exerted. In this study we selected polystyrene particles, both negatively charged and uncharged, and three different sizes (0.05, 0.5 and 6 μm) for testing the effects of size and material properties. Microalgae were exposed to different polystyrene particle sizes and surface charges for 72 h. Effects on microalgal photosynthesis and growth were determined by pulse amplitude modulation fluorometry and flow cytometry, respectively. None of the treatments tested in these experiments had an effect on microalgal photosynthesis. Microalgal growth was negatively affected (up to 45%) by uncharged polystyrene particles, but only at high concentrations (250 mg/L). Additionally, these adverse effects were demonstrated to increase with decreasing particle size.

Abstract: Microplastic contamination in the African Great Lakes is currently unreported, and compared to other regions of the world little is known about the occurrence of microplastics in African waters and their fauna. The present study was conducted in the Mwanza region of Tanzania, located on the southern shore of Lake Victoria. The gastrointestinal tracts of locally fished Nile perch (Lates niloticus) and Nile tilapia (Oreochromis niloticus) were examined for plastics. Plastics were confirmed in 20% of fish from each species by Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR) spectroscopy. A variety of polymer types were identified with likely sources being urban waste and consumer use. Although further research is required to fully assess the impact of plastic pollution in this region, our study is the first to report the presence of microplastics in Africa’s Great Lakes and within the fish species that inhabit them.

On the Hunt for Shipping Containers Lost off California Coast

December 16, 2015 by Office of Response and Restoration

On December 11, 2015, the Matson container ship M/V Manoa was en route to Seattle from Oakland, California, when it lost 12 large containers in heavy seas. At the time of the spill, the ship was maneuvering in order to allow the San Francisco Bay harbor pilot to disembark.

The containers, which are 40 feet long and 9 feet wide, are reported as empty except for miscellaneous packing materials, such as plastic crates and packing materials such as Styrofoam. Luckily there were no hazardous materials in the cargo that was spilled.

The accident occurred about eight miles outside of the Golden Gate Bridge in the Greater Farallones National Marine Sanctuary. Three containers have come ashore, two at or near Baker Beach, just south of the Golden Gate Bridge, and one at Mori Point near Pacifica, California. The search continues for the others.

Abstract: Microplastics provide a mechanism for the long-range transport of hydrophobic chemical contaminants to remote coastal and marine locations. In this study, plastic resin pellets were collected from Zhengmingsi Beach and Dongshan Beach in China. The collected pellets were analyzed for PAHs, PCBs, HCHs, DDTs, chlordane, heptachlor, endosulfan, aldrin, dieldrin and endrin. The total concentration of PCBs ranged from 34.7–213.7 ng g−1 and from 21.5–323.2 ng g−1 in plastic resin pellets for Zhengmingsi Beach and Dongshan Beach respectively. The highest concentrations of PCBs were observed for congeners 44, 110, 138, 155 and 200. The total concentration of PAHs ranged from 136.3–1586.9 ng g−1 and from 397.6–2384.2 ng g−1 in the plastic pellets, whereas DDTs concentration ranged from 1.2–101.5 ng g−1 and from 1.5–127.0 ng g−1 for the two beaches. The elevated concentrations of pollutants appear to be related to extensive industrial development, agricultural activity and the use of coal in the area.

Abstract: Large plastic (>5 mm) and microplastic (0.315–5 mm) debris were collected from 25 beaches along the Hong Kong coastline. More than 90% consisted of microplastics. Among the three groups of microplastic debris, expanded polystyrene (EPS) represented 92%, fragments represented 5%, and pellets represented 3%. The mean microplastic abundance for Hong Kong was 5595 items/m2. This number is higher than international averages, indicating that Hong Kong is a hotspot of marine plastic pollution. Microplastic abundance was significantly higher on the west coast than on the east coast, indicating that the Pearl River, which is west of Hong Kong, may be a potential source of plastic debris. The amounts of large plastic and microplastic debris of the same types (EPS and fragments) were positively correlated, suggesting that the fragmentation of large plastic material may increase the quantity of beach microplastic debris.

Abstract: Cosmetic products, such as facial scrubs, have been identified as potentially important primary sources of microplastics to the marine environment. This study characterises, quantifies and then investigates the sorptive properties of plastic microbeads that are used as exfoliants in cosmetics. Polyethylene microbeads were extracted from several products, and shown to have a wide size range (mean diameters between 164 and 327 μm). We estimated that between 4594 and 94,500 microbeads could be released in a single use. To examine the potential for microbeads to accumulate and transport chemicals they were exposed to a binary mixture of 3H-phenanthrene and 14C-DDT in seawater. The potential for transport of sorbed chemicals by microbeads was broadly similar to that of polythene (PE) particles used in previous sorption studies. In conclusion, cosmetic exfoliants are a potentially important, yet preventable source of microplastic contamination in the marine environment.

Abstract: The contamination with microplastic particles and fibres was evaluated on beaches along the German Baltic coast. Sediments were sampled near the Warnow and Oder/Peene estuaries, on Rügen island and along the Rostock coast to derive possible entry pathways. Seasonal variations were monitored along the Rostock coast from March to July 2014. After density separation in saline solution, floating particles were found to be dominated by sand grains. Water surface tension is shown to be sufficient to explain floatation of grains with sizes less than 1.5 mm. Selecting intensely coloured particles and fibres, we find lower limits of the microplastic concentrations of 0–7 particles/kg and 2–11 fibres/kg dry sediment. The largest microplastic contaminations are measured at the Peene outlet into the Baltic Sea and in the North Sea Jade Bay. City discharges, industrial production sites, fishing activity and tourism are the most likely sources for the highest microplastic concentrations.

Abstract: Microplastics (MPs) are a newly recognized type of environmental pollution in aquatic systems; however no monitoring of these contaminants is conducted, mostly due to the lack of routine quantification. In the net samples collected with a 90-μm WP2 net, pelagic MP abundance was quantified by light microscopy and evaluated as a function of inshore–offshore gradient, depth, and season; the same samples were used for zooplankton analysis. The MP abundance was ∼102–104 particles m−3, with no significant inshore–offshore gradient during summer but increasing offshore in winter. MP abundance in deeper layers was positively affected by zooplankton abundance in the upper layers and significantly lower during winter compared to summer. These findings indicate heterogeneity of MP distribution due to biotic and abiotic factors and suggest that samples collected for other purposes can be used for quantification of MPs in the Baltic Sea, thus facilitating integration of MP assessment into existing monitoring schemes.

Abstract: Benthic marine litter along the Portuguese coast, was recorded in 14 trips on stern trawlers covering a distance of 2117 km and an area of 56.2 km2, average depth range 90–349 m. 2034 items of marine litter were registered, 76% were plastics and 38.6% were originated from fishing related activities. Plastic was present in all the trawls and had the highest average density of all litter categories, 50 items km−2.

The highest density of marine litter (178.9 ± 64.0 items km−2) was found in the proximity of the Tagus river mouth, probably related to the high population density in the Lisbon metropolitan area.

This study highlights the need to raise fishermen awareness for the adoption of good environmental practices that will contribute to the reduction of marine litter.

Abstract: We studied abundance, size and polymer type of microplastic down to 10 μm along a transect from the European Coast to the North Atlantic Subtropical Gyre (NASG) using an underway intake filtration technique and Raman micro-spectrometry. Concentrations ranged from 13 to 501 items m− 3. Highest concentrations were observed at the European coast, decreasing towards mid-Atlantic waters but elevated in the western NASG. We observed highest numbers among particles in the 10–20 μm size fraction, whereas the total volume was highest in the 50–80 μm range. Based on a numerical model size-dependent depth profiles of polyethylene microspheres in a range from 10–1000 μm were calculated and show a strong dispersal throughout the surface mixed layer for sizes smaller than 200 μm. From model and field study results we conclude that small microplastic is ubiquitously distributed over the ocean surface layer and has a lower residence time than larger plastic debris in this compartment.

Abstract: Identification and characterisation of microplastic (MP) is a necessary step to evaluate their concentrations, chemical composition and interactions with biota. MP ≥ 10 μm diameter filtered from below the sea surface in the European and subtropical North Atlantic were simultaneously identified by visual microscopy and Raman micro-spectroscopy. Visually identified particles below 100 μm had a significantly lower percentage confirmed by Raman than larger ones indicating that visual identification alone is inappropriate for studies on small microplastics. Sixty-eight percent of visually counted MP (n = 1279) were spectroscopically confirmed being plastic. The percentage varied with type, colour and size of the MP. Fibres had a higher success rate (75%) than particles (64%). We tested Raman micro-spectroscopy applicability for MP identification with respect to varying chemical composition (additives), degradation state and organic matter coating. Partially UV-degraded post-consumer plastics provided identifiable Raman spectra for polymers most common among marine MP, i.e. polyethylene and polypropylene.

Abstract: Ingestion of microplastics by fishes could be an emerging environmental crisis because of the proliferation of plastic pollution in aquatic environments. Microplastics in marine ecosystems are well documented, however only one study has reported percent occurrence of microplastics in freshwater fishes. The purpose of this study was to quantify the occurrences and types of microplastics ingested by fishes within several freshwater drainages of the Gulf of Mexico and an estuary of the Gulf of Mexico. Among 535 fishes examined in this study, 8% of the freshwater fishes and 10% of the marine fishes had microplastics in their gut tract. Percentage occurrence of microplastics ingested by fishes in non-urbanized streams (5%) was less than that of one of the urbanized streams (Neches River; 29%). Percent occurrence of microplastics by habitat (i.e., benthic, pelagic) and trophic guilds (herbivore/omnivore, invertivore, carnivore) were similar. Low but widespread occurrences among drainages, habitat guilds, and trophic guilds indicate proliferation of plastic pollution within watersheds of the Gulf of Mexico, but consequences to fish health are unknown at this time.

Camels & Plastic

by Posted in 2.1 reports, stats and studies Tagged 5 Comments

Every year hundreds of camels die each year from ingesting plastic bags.

“Every day we have a camel that has died in a camel camp. One in every two camels dies from plastic,” Dr. Ulrich Wernery, scientific director at the Central Veterinary Research Laboratory in Dubai told English-language daily Gulf News.

Rocks of calcified plastic weighing up to 60 kilograms are found in camel stomachs every day, said Wernery, whose clinic conducts hundreds of post-mortems on camels, gazelles, sheep and cows.

Wernery said the curious animals nibble on plastic bags that are thrown from car windows or dumped in the desert by campers and day-trippers.

The veteran animal doctor told Gulf News that the animals ingest plastic bags and ropes which then calcify in their stomach. The heavy rocks or balls fill up the stomach and make it impossible for the animals to eat, causing them to eventually die of starvation.

“Camel calves are the worst affected because they are so curious,” he added.

Calling for an end to the “fatal pollution,” Wernery said residents must stop polluting the desert with plastic.

“I’ve been here for twenty years and first noticed this about fifteen years ago,” said Wernery, adding that the situation is getting worse by the year.

Wernery said he was shocked after a recent visit to a desert area in the northern UAE emirate of Ras Al Khaimah, where owners had dumped the bodies of animals that had died from plastic ingestion.

“I counted more than 30 carcasses and I named the place ‘Death Valley’,” he said.

The Hebridean Whale and Dolphin Trust took various skin and blubber samples and removed the stomach for further study by the Scottish Agricultural College. On initial removal it was found that the entrance to the stomach was completely blocked with a cylinder of tightly packed shredded black plastic binliner bags and fishing twine.

It is believed that this made it difficult for the animal to forage and feed effectively. This would have a biologically significant impact on the animal’s ability to survive. Full analysis of the stomach contents is currently being undertaken. Cuviers Beaked whales usually prey on squid and catch their prey through the action of suction. It is believed that Cuviers Beaked whales mistake plastic bags in the water column for their prey species squid and ingest them.

In previous years a number of Cuviers Beaked whales stranded in Scotland have been found to have plastic bags in their stomachs. For any more details on this case please contact the Hebridean Whale and Dolphin Trust at 28 Main Street. Tobermory. Isle of Mull. Scotland. PA75 6NU. 01688 302620. email info@hwdt.org”

Elephants & Plastic

by Posted in 2.1 reports, stats and studies Tagged 3 Comments

Wild life vet Jerry Haigh writes “Meanwhile three elephants in Chobe National Park died after eating trash from the Chobe landfill.”

A senior Wildlife Biologist, Mr Keagapetse Mosugelo said the elephants died as a result of plastics they ate in the landfill.

“The situation at the landfill is not good for animals,”

he said, adding that the electric fence that has been installed is not sufficient as birds will still flying in to eat waste.

Chobe, which is a fascinating park that lies right in the north of Botswana, is one of the areas on the continent where elephants have created their own min-deserts as they are so abundant that have almost eaten themselves out of house and home.

A large Sugar Gum tree branch fell down in the local school over summer. I had a look and in the branches was a dead magpie and a nest. There was plastic tangled around the magpie’s foot. It looks as though the parents used some plastic in the building of the nest. When the youngster grew up he became tangled and couldn’t fly. He must have starved to death, hanging upside down by his foot.

Abstract: Anthropogenic debris is ubiquitous in the marine environment
and has been reported to negatively impact hundreds of species globally.
Seabirds are particularly at risk from entanglement in debris due to
their habit of collecting food and, in many cases, nesting material off
the ocean’s surface. We compared the prevalence and composition of
debris in nests and along the beach at two Brown Booby (Sula
leucogaster) colonies on Ashmore Reef, Timor Sea, a remote area known to
contain high densities of debris transported by ocean currents. The
proportion of nests with debris varied across islands (range 3–31%),
likely in response to the availability of natural nesting materials.
Boobies exhibited a preference for debris colour (white and black), but
not type. The ephemeral nature of Brown Booby nests on Ashmore Reef may
limit their utility as indicators of marine pollution, however
monitoring is recommended in light of increasing demand for plastic
products.

Plastics & Birds

by Posted in 2.1 reports, stats and studies Tagged 2 Comments

Click here for the slide show

A Dutch study in the North Sea of fulmar seabirds concluded 95 per cent of the birds had plastic in their stomachs. More than 1600 pieces were found in the stomach of one bird in Belgium.

Since his first encounter with the gyre in 1997, Moore created the Algalita Marine Research Foundation to help study the problem. Canadian filmmaker Ian Connacher joined Moore last year to film the garbage patch for his documentary, I Am Plastic.

“The most menacing part is those little bits of plastic start looking like food for certain animals, or the filter feeders don’t have any choice, they just pick them up,” noted Connacher.

Perhaps an even bigger problem is hiding beneath the surface of the islands of garbage. Greenpeace reports that about 70 per cent of the plastic that makes it to the ocean sinks to the bottom, where it then smothers marine life on the ocean floor. Dutch scientists have found 600,000 tons of discarded plastic on the bottom of the North Sea alone.

A study by the Japanese geochemist Hideshige Takada and his colleagues at Tokyo University in 2001 found that plastic polymers soak up the resilient poisons such as DDT and polychlorinated biphenyls. The researchers found that non-water-soluble toxic chemicals can be found in plastic in levels as high as a million times their concentration in water. As small pieces of plastic are mistaken for fish eggs and other food by marine life, these toxins end up at the dinner table. But even without the extra toxins, eating plastic is hazardous to health.

Clothes hangers

by Posted in 2.1 reports, stats and studies, 3.1 House, Office & Garden, 3.1.7 wear Tagged 7 Comments

Plastic coat hangers? I hate them. They are rubbish, break easily and are bad for your clothes.
They are usually given away with a purchase of clothing..
Even if you refuse the hanger don’t fondly think it is automatically going to be reused. Many clothes now are bought, ready- hung from the manufacturer. They are not hung in store.
Some of the larger coat hangers may be reused at home but there is a limit to how many coat hangers you need.

And if you are talking knickers vests and the like, those hangers are little more than one-use disposables. Unless you have a strange fetish for them, you don’t keep them and the stores certainly don’t reuse them.

The amount of waste created by these disposable hangers in phenomenal. It is claimed the USA alone they get through 8 billion plastic /wire hangers a year . – enough to fill the empire states building 4 times over. You can  find a lot more statistics on hanger abuse here.

And no recycling is not the answer!

Saying NO to plastic coat hangers

Refuse – I try to buy un-hung clothes when ever possible. That means clothes that are not displayed on hangers.

  1. What To Do With Plastic Hangers

    Reuse – but if you do end up with unwanted hangers you can try giving them away.  Charity shops sometimes need more coat hangers and you can often get rid of them them via  free cycle.

    Return I don’t have many clothes that need dry cleaning, but when I do get that done, I return the hanger.

    Plastic Free Alternatives

    At Home

    Wooden Hangers At home I hang my clothes on wooden hangers. I buy mine from wherever I see them (including Ikea).

    In Shops

    If you are a shop owner or dry cleaner and you really need a disposable hanger – here’s are some addresses for cardboard hangers you can recycle.

    U.K Hangers Of London

    Defenda are made in the U.K.

    If you are questioning your use of plastic or wire coat hangers, due to the environmentally devastating effect their disposal has on landfill each year, you will be delighted to know that an alternative exists.

    DEFENDA Green Hangers Are Environmentally Friendly Corrugated Cardboard Clothes Hangers / Coat Hangers.
    UK Manufactured For Reduced Import Miles

    These Strong ECO-FRIENDLY Corrugated Alternatives To Plastic & Metal Wire Coat Hangers Are Produced From Recycled Corrugated Board & Are 100% Recyclable. They Are Ideal For Commercial Or Domestic Use i.e. Dry Cleaning Companies, Laundrettes, Clothes Shops / Retailers etc

    They Are Also A Safer Option For Organisations Where Safety Is a Concern Such As: HM Prison Services, Mental Health Facilities, Care & Nursing Homes & Many Other Institutions Where Metal Or Plastic Hangers Can Be Used As Weapons Or Allow For Self-Harming Among Patients.

    SUPPLIED TO UK & EUROPEAN COUNTRIES – CALL COVENTRY 02476 422000 FOR INFORMATION

    Or these Normn Hangers

    The Solid Board that the hangers are made from is 100% recycled. The hangers too are 100% recyclable after you are done using them. So when its time for fresh ones, you can just pop the old ones into the paper recycling and they’ll re-surface perhaps as a paper cup, stationary or maybe even into a new, cool sustainable hanger. PLUS our hangers are printed with vegetable-based inks – they do absolutely no harm to nature.

    Sustainability in manufacturing

    All our hangers are produced by our exclusive partner Smurfit Kappa. They are one of the world’s largest integrated manufacturers of paper-based packaging products. They have also won several sustainability awards. We continuously work closely with Smurfit Kappa to research and develop new models of perfectly crafted, sustainable hangers.

    Abroad

    USA 

    This company are promoting a solution; a fibre board biodegradable hanger and a campaign against the plastic hanger . Here is their promotional material

    Plastic hanger facts
    Approximately 85% of plastic retail hangers no reused or recycled
    90% of America’s clothes now imported
    30-40 billion clothes come into the United States on plastic hangers
    85% of 30-40 billion is 25. > 34 billion hangers into landfills every year.
    34 billion landfilled hangers would fill almost 20 Empire State Buildings
    40 billion hangers end to end would stretch 8 million miles, far beyond the orbit of the moon—every year.
    Polystyrene hangers off-gas benzene in clothing and leaches benzene into the ground water.
    Polycarbonate hangers leach bisphenol-a into ground water.
    Plastic hangers take over 1,000 years to break down in an anerobic landfill. All for a one-time use.
    Why so many hangers?
    Growing industry trend of one-use plastic hangers
    Garments on Hangers (GOH) – hangers are put on clothing overseas by clothing manufacturer and shipped to store already on hanger
    Each hanger is one-use and garment replacing sold product has it’s own hanger.
    Hanger is now outsourced to clothing manufacturer who includes the price of the hanger into their Cost of Goods (COG)
    Its cheaper for the clothing retailer to use one-use hangers but plastic is a poor material to make any product that is one-use, especially one with so much plastic in it.
    Companies who use Garment on Hangers are Wal-Mart, Old Navy, C&A, Target, Kmart, Coles and most department stores.
    Aren’t plastic hangers recyclable?
    Cheaper to landfill than to recycle
    Cheaper to make new plastic hangers than recycle
    Multiple materials (metal hook and clips, rubber or vinyl no-slip pads, 7 different types of plastic) make recycling impractical if not impossible.
    Where do plastic hangers go if I don’t take them after I buy clothing? Answer: in a box under the counter then out to the back.
    How much waste per store?
    One clothing company’s flagship store in San Francisco that uses the GOH system said
    They throw away approximately 95% of their plastic hangers every day.
    They replace from 8,000 to 28,000 garments everyday
    That means they throw away from 7,600 to 26,600 hangers every day.
    Why do companies that say they are green use such a wasteful system where up to 19.5 Empire State Buildings of plastic hangers landfilled?
    Because hangers are invisible to the consumer
    The wire hanger was patented in 1890
    The plastic retail hanger was invented in the 60’s
    There’s been no innovation, so the hangers have become invisible
    They are so prevalent that no one sees them anymore
    Hanger companies and retail clothing companies are very quiet about this extreme waste stream
    Hanger companies stay in business
    Retailers save by using one-use GOH plastic hangers

    What’s the solution?
    Tell your local retailer that you do not like plastic hangers in stores that you buy at.
    that up to 34 billion of those plastic retail hangers go into your municipal landfill.
    that they are not green if they use plastic hangers – even recycled plastic hangers.
    Tell them that 85% of all plastic hangers end up in landfills.
    Tell them to use a sustainable material such as paper fiberboard hangers that can be recycled at the store or at consumer curbside pickups
    Join the Anti Plastic Hanger Movement and stop the 36 billion plastic hangers that get thrown into local landfills everyyear to save retail companies money!

Plastic eating microbes

by Posted in 2.1 reports, stats and studies Tagged 1 Comment

Is this a good idea?- much as I hate bad plastic I am rather attached to the computer and Dyson. Will they disappear before my very eyes. Here are some reports on plastic degrading microbes

Daniel Burd, a student at Waterloo Collegiate Institute, recently demonstrated that certain types of bacteria can break down plastic. During his scientific research, Daniel discovered that some types of bacteria in the soil can effectively degrade polyethylene plastic. He eventually isolated two microbial strains belonging to the genus Sphingomonas and Pseudomonas . Here’s a link to his research paper.

You can isolate your own plastic degrading microbes here http://www.instructables.com/id/How-to-isolate-plastic-degrading-bacteria-from-soi/?ALLSTEPS

According to Wikkipedia Nylon 4 or polybutyrolactam can be degraded by the (ND-10 and ND-11) strands of Pseudomonas sp. found in sludge. This produces γ-aminobutyric acid (GABA) as a byproduct.[1]Nylon 4 is thermally unstable.[2]

Studies

The nylon4 portion in the blend films composed of nylon4 and nylon6 was degraded and completely disappeared within 4 months in two kinds of composted soils gathered from different university farms as well as pure nylon4 film reported previously, while the nylon6 portion remained even after the burial test for 15 months. Nylon4 powder was also degraded to carbon dioxide in the degradation test in an activated sludge obtained from a sewage disposal institution in Kogakuin University. Three species of microoganisms (i.e., ascomytous fungi) were isolated through the inoculation from the nylon4 film partially degraded in the soil on a medium containing nylon4 powder as a carbon source. © 2002 Wiley Periodicals, Inc.
