Coffee – Instant
When I first started my boycott, the only way to get plasticfree coffee was to buy the beans loose and grind them. Now theres all kinds of options from instant in your own bag to compostable pods
For other coffee posts check out our index. You will also find tea, cocoa, milk in glass bottles and something stronger.
But back to the coffee….
Finally managed to score some plastic free instant coffee! Its back to the wonderful Leeds Market. I love it. Its a fantastic place to buy local, #plasticfree almost everything. Read a review here
The JarTree is where I got my coffee. Its a great stall where you can take your own packaging and buy just about everything you might ever need, plastic free.

Coffee single-cup brewing system
When I first started my boycott, the only way to get plasticfree coffee was to buy the beans loose and grind them. Now theres all kinds of options from instant in your own bag to compostable pods
For other coffee posts check out our index. You will also find tea, cocoa, milk in glass bottles and something stronger.
But back to the coffee….
“Peter Sylvan and John Dragone in the early 1990s started building prototypes of a coffee maker that would brew one cup at a time, using a throwaway package that would hold the grounds and the filter. The result was the Keurig single-cup brewing system, which uses disposable plastic K-Cups that look like supersize creamer containers.”
“When the company began selling its single-serve coffee systems to offices, the price was too high to envision a similar product living on kitchen countertops: $795. But by 2004, the company had created a consumer version that sold for $149. (Keurig’s least expensive machine, the B30 Mini, currently sells for $89.)” Read more
By 2017….
coffee pods made up a nearly 5 billion dollar industry.
at least 16 million U.S. households currently have a single-serve brewer on their countertop.
coffee pods, or K-cups, that go in them… and make up a third of all coffee sold.
if you took the coffee pods that the coffee giant Nespresso produced over the years (nearly 30 billion of them), you could circle the globe over two dozen times!
That’s a lot of pods, a lot of plastic, and a lot of aluminium.
Sources for the above facts and a very good article can be found here.So what to do if you have one of these machines?
Compostable Pods
You could try compostable pods. Such as these from Novelle Coffee
“Our dedication to provide premium coffee is matched only by our commitment to the environment, which is why our coffee is now available in compostable Nespresso compatible capsules.
Available in Intenso and Decaffeinato, it’s the same great ethically-sourced Novell coffee with added peace of mind.
Our capsules are made from 100% compostable materials that decompose over 12 weeks, meaning you can look after the planet as well as your conscience.” Read moreReportedly the North American brands Purpods and G-Pak have also been certified 100% compostable.
Halo do something similar.
I dont have a coffee making machine so cannot compare taste… but Which have done a survey that you can access here.
Compostable Plastics
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. You can find out more here.
Composting Plastic At Home
While most agree that some plastics are indeed compostable, many say that it can only composted in large scale municipal schemes. As we don’t have many large scale municipal schemes this they say is a pointless advantage. I say the days of large scale municipal schemes is fast approaching as governments aim to divert biodegradable rubbish from landfill sites.
But more to the point, I have been composting my compostable plastic at home for years now, including Biobags, deli pots and disposable cutlery. Read more about that HERE.
It does take longer than other products and sometimes I have found shreds of it in my compost but I dig it into the soil where it quickly disappears.Read more about compostable plastics here

Gels
Xanthan Gum
Xanthan gum is a polysaccharide with many industrial uses, including as a common food additive. It is an effective thickening agent and stabilizer to prevent ingredients from separating. It can be produced from simple sugars using a fermentation process, and derives its name from the species of bacteria used, Xanthomonas campestris.
Wikipedia
It can be used in lieu of gelatine. Measure out half the amount of xanthan gum. ie for i 2 tbsp. of gelatin, use 1 tbsp. of xanthan gum. For baked products, add around 1 tsp. for every cup of flour added.
Hyaluronate Acid
Sodium hyaluronate is the sodium salt of hyaluronic acid, a glycosaminoglycan found in various connective tissue of humans.Wikipedia
Hyaluronate Acid is
A white powder with no aroma. Commercially, much of it is sourced from poultry (rooster combs) which we refuse to stock. The type we have sourced is made by producing enzymes from a bacteria based biofermentation process. It is guaranteed to be animal free.
1 gr Sodium Hyaluronate
98,4 gr Distilled Water
If you have an air conditioning system or an electric dehumidifier, you can use the water which accumulates during their use as well. The dehumidifier usually has a container the water is collected in. Household air conditioners have an external compressor water tends to fall under, so place a bucket underneath and collect the water that way. https://thewatergeeks.com/how-to-distill-water/She suggests adding a preservative but I don’t as preservatives react with my skin.
weigh the Sodium Hyaluronate and the water
Pour the Sodium Hyaluronate on top of the water“At this point some people like to mix it and some people like to let it be.
I have actually tried both ways and here is my experience: if you try to mix it at this stage, part of the SH will stick to the spoon. This means that a precious part of your gel will get lost (and SH is not exactly cheap, so you’d want to mind this).
IMO it is better to let the SH hydrate by itself on top of the water for a while, and stir later.4) Cover the glass with plastic film and let it rest in the fridge for few hours.
5) After few hours the SH will be hydrated. Now you can stir it with a spoon so to make the gel more smooth (there will be harder parts and softer parts).
6) Add your preservative, stir again and put in a bottle 🙂
You can use this Gel by itself, for its great hydrating properties!
If you have a very dry skin you could like to use it before applying your cream 🙂
You could also make a more luxurious gel by substituting part of the water (or the entire water) with Rose water!As you might have noticed in the market we can find creams or serums that say “40% Hyaluronic Acid”.
Well, as you can see I am using 1% of Sodium Hyaluronate and this is the highest concentration I can use.Check out all our home made make here

Water Bottled
Yes I know many of us consider tap to be the only option but for those of you who love bottled water there are choices. But before we begin lets remind ourselves why water in plastic bottles is an abomination
Why Not Bottled Water
Some articles on the subject
here
And here
And this about PET plastic bottles
So much so that water bottle bans are becoming more commonPlastic Free Bottled Water
But what to do if you don’t like tap? You can of course get water in glass bottles from shops and supermarkets. Buts its heavy and glass comes with its own environmental impact. Really glass bottles are only sustainable when they can be refilled. Read more here
So this is very good news… water in returnable, refillable bottles!
Returnable Bottles
“Crag water are the only bottled spring water company in the North of England that reuses its glass bottles. By that we mean that we will deliver and collect then send back to be washed, sanitised and refill the bottles. The only part of what we supply that isn’t reused is the aluminium cap. This is a security thing. Each cap has a use once only breakable seal.We sell both still and sparkling spring water in 330ml and 750ml bottles. The sparkling water has a natural soft taste and is carbonated lightly.”
You can get them delivered to your doorstep along with your milk in bottles!
To find out more visit the website.Compostable Bottles
We are always on the look out for new and greener plastics and these PLA bottles caught our eye. Personally I think bottled water is a scam. Why pay good money for that you can get for free? But if you should choose to go down that route, it seems a shame that such a decision should also result in a landfill site of non-biodegradable, plastic bottles.
There are of course compostable, biodegradable plastics – one such is PLA. But for years PLA was not considered up to the job of beverage bottle. You can read more about PLA plastic here.
The following would seem to disprove that theory….
From the website… Eco for life bottles are made from Polylactic acid, PLA for short.
During the production process, we produce 60% less greenhouse gases and use 50% less fossil fuels.Will bio-degrade ✘ No, takes up to 1000 years Yes, in an industrial composter Made from ✘ Oil Annually renewable plants Leaches harmful chemicals into water ✘ Yes No Can be recycled ✘ Yes, but down-cycled and always ends up in landfill Yes, and can be re-cycled into a whole new bottle, never ending in landfill Releases harmful toxins when incinerated ✘ Yes No Greenhouse gases savings during production ✘– Approx. 60% Oil saved ✘– Approx. 1 litre for every 24 bottles N.B. I still don’t know if the screw top lids are PLA plastic.
Composting PLA Plastic
Back to me…. While most agree that PLA plastic is indeed compostable, many say that it can only composted in large scale municipal schemes. As we don’t have many large scale municipal schemes this they say is a pointless advantage.
I say the days of large scale municipal schemes is fast approaching as governments aim to divert biodegradable rubbish from landfill sites.
Moreover I have been composting my PLA plastic for years.
We have used and composted the following PLA plastic products ( including Biobags , Deli pots and disposable Cutlery )
Useful stuff to know
Remember, not all bio- plastics can be composted and some are not as green as they sound

Supermarkets
Some time you have to use them.
Morrisons is to become the first supermarket chain to remove packaging from its fruit and vegetables.
The company said customers would be able to choose from up to 127 varieties of fruit and veg in many of its stores, buying them loose or putting them in recyclable paper bags.
However, there will continue to be a neighbouring section where customers can still buy packaged veg, if they choose
The move follows a ten-month trial in three English stores where the amount of loose fruit and veg bought by customers increased by an average of 40 per cent.

Elastine
I wear mostly natural fibres but occasionally have problems with elasticine. I thought this referred to elastic. So when the label said 95% cotton 5% elasticine I thought the article of clothing contained elastic. I was kind of confused to find my jeans contained elastic but considered it essential in my knickers. Obviously more research was needed.
What is elasticine? also called Spandex or Lycra
elastane is a synthetic fiber known for its exceptional elasticity. It can be stretched up to 7 times it’s own length and snaps back into shape. So yes like elastic in that sense.
BUT rather than a stretchy piece of white stuff threaded through your waistband, it is used in a blend with other fibres. It is often mixed with natural fibres such as cotton to help them keep their shape.
There are two principal methods used in processing elastane. One is to wrap the elastane fibre in a non-elastic thread – either natural or man-made. The resulting yarn has the appearance and feel of the outer fibre used. The second method involves using pure elastane threads, which are worked or woven into fabrics made from other fibres. The added elasticity makes such fabrics more comfortable to wear. Blends with elastane depend on the type of fabric and the end use.
On care labels elastane is often designated as “EL”.
For cotton clothes that need a lot of stretch like socks and knickers it is almost impossible to find them elasticine free.
Why is this a problem?
It is a polyether polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPonts Wikipedia
Basically it is a non biodegradable plastic. The problem with non biodegradable plastic fibres is that they shed when the fabric containing them is washed. They are then swooshed into the drains in the waste water and, too fine to be filtered out, they end up the rivers and sea. Once there, being plastic, they don’t biodegrade. They are now amongst other problems, being eaten by plankton with worrying effects.
And then there is this….”Spandex is made from several chemicals that are known sensitizers. TDI and MDI (Toluene-2,4-diisocyanate; Methylene bisphenyl-4,4-diiisocyanate) are precursors of the polyurethane used to make spandex. TDI, a toxic chemical, has proved carcinogenic and can cause severe dermatitis. MDI is also toxic. Manufacturers of spandex products must use strict quality control procedures to ensure that no residual unreacted MDI or TDI exists in the final product.
Why I boycott….
Seemingly, wherever scientists look, they’re finding plastic fibers contaminating the environment. Often, plastic textile fibers are the dominant source of plastic pollution found in surveys. Plastic fibers have been found in the sediment surrounding beaches, in mangrove groves, and in Arctic ice — even in products we eat and drink. “The average person ingests over 5,800 particles of synthetic debris” a year, a recent paper in PLOS finds. And most of those particles are plastic fibers.

Cork
Flexible Rubber cork
Nitrile rubber is synthetic rubber. it can be used to bond cork to make a flexible sheet
like Klinger NI27 Rubber Bonded Cork
Klinger rubber bonded cork is bonded with synthetic rubber, it provides the compressibility of cork with the resilience of rubber. This material has high mechanical strength.
Manufactured from high quality cork oak bonded with synthetic rubber
Rubber cork sheets are made from cork aggregate and different rubber mixes, neoprene, silicone and polyurethane. The final product is incredibly elastic, durable and resistant against grease, oil, fuels, gases and many other chemical substances. It is used as a seal material for cars, agricultural machines and industry seals. Read more.But you can get expanded cork boards that don’t use synthetic binders.
Expanded insulation cork sheets are natural, balanced and unbeatable cork products that, with this special type of agglomerated cork, do not contain polyurethane or any other fillers or additives. Due to the high temperature processing treatment it expands (similarly to popcorn) and suberin that is releases during is a natural adhesive that binds the expanding grains. This way we produce a wonderful, natural and sustainable material that offers a perfect vibroisolation, thermal insulation and acoustic isolation.

Some notes on insulation
The green van. You can see all our related posts here
Thermal conductivity, often denoted by the greek symbol λ ,measures of how easily heat flows through a material, independent of the thickness of the material in question.
The lower the thermal conductivity = the slower heat will move across a material= good
It is measured in Watts per Metre Kelvin (W/mK).
0.008 W/mK for vacuum insulated panels = very good = retains heat
0.061 W/mK for certain types of wood fibre = not so good looses heat
R-Values
The R-value is a measure of resistance to heat flow through a given thickness of material.
The higher the R-value the better its insulating properties.
The R-value is calculated by using the formula
Where:
l is the thickness of the material in metres and
λ is the thermal conductivity in W/mK.
The R-value is measured in metres squared Kelvin per Watt (m2K/W)
“The R-value is therefore a relatively simple way to compare two insulating materials if you have the thermal conductivity for each material. It also allows you to see the impact of adding thicker layers of the same insulating material.”
But ” R-values only take into account conduction. It does not include either convection or radiation.”
so on to
U-Values
takes into account all factors and is the most reliable method of measuring but it is more difficult to calculate.
“The U value of a building element is the inverse of the total thermal resistance of that element. The U-value is a measure of how much heat is lost through a given thickness of a particular material, but includes the three major ways in which heat loss occurs – conduction, convection and radiation.”
To Conclude
- Thermal Resistance = how fast heat passes through a material independent of thicknessshown as λ / W/mK .The higher the number the better
- R-Values takes the thickness of the material into account – so thermal resistance in more detail. (m2K/W) Again higher is better.
- U-Values.
- The U-Value is the most accurate measurement of a material’s insulating ability, In this case THE LOWER the number the better.
Very good read HERE
Why should I insulate and where?
A useful ARTICLE HERE.
For our van, we used Elephant Bark 1/4″ rubber (also called Stall Mats) as an MLV-type layer on the floor. We isolated it from the stock wooden van floor using a layer of LowE foil-faced closed cell foam. The full stack of materials gives us a good combination of heat and sound damping.
On the walls, we used DB2-4walls. It’s a .75lb/sf. product, 1/8″ thick. We didn’t use it throughout the van, but we did put sheets of it behind the door panels before we re-applied them.
(thats 6.35mm thick!)
From a useful ARTICLE.
used rubber on the floor
- Rubber rolls can be installed in minutes with 2-sided carpet tape, no messy adhesive needed
- Rubberized flooring made from abrasion and wear resistant 100-Percent USA produce recycled rubber
- Extremely durable which makes this product ideal for deck flooring or dog mats for kennels
- This rubber flooring roll is an excellent way to turn your concrete floors into comfortable, warm, and protective rubber surfaces

Why can insulation cause damp?
As you’ll know, insulation is designed to slow down heat transfer, keeping warm air in and cold air out. However, the more airtight your house is, the less natural ventilation it gets – and airflow is key for maintaining a healthy level of humidity indoors.
What people are often not told by insulation installers is that warm air holds more moisture, and this has got to go somewhere. If insulation means this water vapour cannot escape through walls or ceilings, it sinks into the fabric of the building, or its contents. It is important therefore to counter increased humidity with increased ventilation. Make sure to use extractor fans and/or open windows – especially when you’re doing something that creates a lot of steam, such as showering or cooking.
Damp after loft insulation
So you only “decided to insulate the floor of the space, rather than the roof. This is because there is very little point paying to heat your attic – and the nature of heat rising means that a lot of heating escapes up there! Insulating this space effectively will keep warm air in the main body of the house below, and your loft will get pretty cold as a result. As long as it is dry up there, this shouldn’t be an issue if you’re only going up now and then to grab boxes. Potential problems can arise when damp air gets into the space and reaches its dew point in the low temperature, condensing on surfaces, (and in some cases, the insulation material itself). Damp can set in and lead to mould, which can be tricky to get rid of. This is why it’s important to have adequate ventilation in the roof, and make sure any insulation doesn’t cover the vents. Something else you should consider carefully is the material you choose, as their abilities to resist damp vary hugely. If you use an insulation material that is not breathable, it soaks up water and keeps it there. Fibreglass, for instance, is easily soiled – and once it’s wet, it stays that way. Pure sheep wool, in comparison, helps regulate humidity in the air wherever it is. It can be more easily dried out, and its thermal performance is not affected when it holds water vapour.

HOW TO CALCULATE HOW MUCH YOU NEED:
Using the thermal conductivity of this product (0.0385), you can work out either the thickness you require or the U-Value you will achieve. Simply divide the thermal conductivity by the thickness to work out the U-Value, or divide it by the U-value you want to reach to work out the thickness required.
0.0385 / Thickness = U-Value0.0385 / U-Value = Thickness
