Some of your questions answered
 
Q: What are Bioplastics
A: Bioplastics are a new generation of compostable and biodegradeable plastics made from natural, renewable materials such as corn and potatoes
Q: What is the difference between biodegradable and compostable?
A: A biodegradable material is one that can break down safely and quickly, through a natural biological process, back into one of natures raw materials and seemlessly into the environment, this can take upto to 10 years and still leaves small particles of plastic that can easily get inot the food chain. A product that is compostable is one that can be mixed into a composition of decaying biodegradeable materials and eventually turns into a useable material such as fertiliser.
Q: What is EN 13432
A: Standard EN 13432 – Proof of compostability of plastic products
Plastic products can provide proof of their compostability by successfully meeting the harmonised European standard, EN 13432. The European Packaging Directive 94/62 EC makes reference hereto with regard to compliance with recovery directives.
Scope of testing under EN 13432
Chemical test: Disclosure of all constituents, threshold values for heavy metals are to be adhered to.
Biodegradability in watery medium (oxygen consumption and production of CO2): Proof must be made that at least 90% of the organic material is converted into CO2 within 6 months.
Disintegration in compost: After 3 months’ composting and subsequent sifting through a 2 mm sieve, no more than 10% residue may remain, as compared to the original mass.
Practical test of compostability in a semi-industrial (or industrial) composting facility: No negative influence on the composting process is permitted.
Compost application: Examination of the effect of resultant compost on plant growth(agronomic test), ecotoxicity test.
The maximum material gauge of a plastic is determined by its compostability in standard practice composting operations. All tests must be passed. Success in individual tests will not be sufficient. The EN standard test methods are based on the scientific definitions of the ISO standards 18451, 18452 (aerobic degradability in water), 18453 (anaerobic degradability in water) und 18455 (aerobic composting). The tests must be conducted by recognised test laboratories (address list is available from certifying bodies).
Q:  Can I use Compi Sax liners for my kerbside collection in Somerset?
A: How can I keep my food waste container clean?
You can use newspaper to wrap food waste or line the caddies.You can also purchase compostable liners from local shops. These must be certified for composting and be printed with the 'looped seedling' logo shown.

Please do NOT line your food waste bins with plastic bags, even if they are biodegradable as these do not rot down in the composting process and we will be unable to collect your food waste. Only compostable liners with the 'looped seedling' certification logo can be used.
