An estimated 6.7 million tonnes of food waste is collected by UK Local Authorities and sent to landfill.
This is approximately 150-250 Kg per household per year (ref. WRAP, 2010). Around 7m UK homes already home compost, but they compost as little as 35% of their total food waste. Typically adding vegetable peelings and tea bags, but not plate scrapping, meat, fish, cooked food, rice, pasta, leftover bread, cakes, etc. The main reason food waste is not composted at home is smell, vermin, yuck and mess (ref Defra funded, Brook-Lyndhurst 2008).
Home composting of all food waste has environmental benefits as it reduces fuel used to collect and transport waste to landfill, prevents methane release in landfill, [methane is a potent greenhouse gas] and reduces the number of new industrial composting / anaerobic digestion plants required in the UK.
