A roll of compost-a-bag, a 100% biodegradable bin liner handed out to residents by Bournemouth Borough Council in 2014 for the weekly collection of food waste. Designed to fit into the small, brown coloured caddies issued to local households, the liners are made from cornstarch polymers that break down in approximately 45 days into carbon dioxide and water. They are printed with soy-based inks and certified to EN13432 as being compostable. The intention of the scheme was to separate both raw and cooked food from normal rubbish streams in order to boost recycling rates. The food waste was sent to Eco Sustainable Solutions in Dorset, where it was broken down through anaerobic digestion to create biofertiliser.
