Wiltshire County Council is encouraging householders to get rid of their food waste by trialling out a food waste digester system. The Green Cone has been subsidised by the council for distribution to Wiltshire residents. It is used in the garden, and reduces food waste to its natural components of water and carbon dioxide, leaving only a small residue at the bottom of the unit. In a bid to divert waste from landfill, the council thinks that up to a third of the contents of an average household bin could be recycled in this way. It plans to trial 2,000 Green Cones, of which over 1,000 have already been sold at a cost of £15-£20. Councillor Toby Sturgis said: People are keen to be green, that is why we already recycle nearly 40% of our household waste, but we know people want to do more. I was appalled to find out that surveys show the average Wiltshire household throws £400 worth of food away a year. It is not sustainable to keep on burying this rubbish in the ground. It is expensive and it produces greenhouse gases. The Green Cone comprises a four-part injection moulded unit featuring a lower basket below ground and forming the base for an upper assembly consisting of a black inner cone and a green outer lidded plastic cone. The unit utilises a solar heating effect between the inner and outer cones to promote air circulation, which facilitates the growth of micro-organisms and the aerobic digestion process. Green Cone managing director John Cockram said: Implementing an efficient and affordable waste management strategy is at the top of every local authoritys agenda. By installing a Green Cone, these objectives will be met but with pressure on society to reduce greenhouse gas emissions, due to our solar powered unit no additional energy consumption is necessary. Its a win-win situation.
