I did hear on the radio this week that there is to be a funding boost to develop more anaerobic digestion plants within the UK. Something like £10m was mentioned. Trouble is I can find nothing about this on the internet. So, if anyone can help with this story, please do. (and EP now has; see comments below).
Scotland does have help with a £6m funding programme called The Organics Capital Grant Scheme. It’s spread over 3 years – £0.9 million in 2007-08, £2.15 million in 2008-09 and £3 million in 2009-10. This is part of an ongoing programme started in 2003, to look at different methods of dealing with waste and avoiding using landfill. See more here.
WRAP will provide up to 30 per cent of the capital cost of in-vessel composters (IVCs), anaerobic digesters (ADs) and thermophilic aerobic digesters (TADs). These plants are capable of treating organic waste (garden waste and food waste). By 2011, WRAP aim to have established an additional 125,000 tonnes of capacity in Scotland to treat organic waste.
Premier Waste Management and CiViC Environmental Systems have developed the Premier Advanced Recycling Centre (PARC), an integrated system which uses bio-processing technology to process MSW, recycling metals, glass, plastic and aerobically-digesting biodegradable materials into a compost/compost-like output which is used to manufacture a range of products including a topsoil called Parc-gro.
Based in Thornley, Durham this advanced biological treatment Demonstrator uses aerobic digestion to process up to 20,000 tonnes of Municipal Solid Waste (MSW) per year through a vertical in-vessel composting tower.
How PARC works.
The process starts with the loading of MSW into a shredder for size reduction. Shredded waste is then loaded by conveyor into the top of three
composting compartments. Each composting compartment contains a large 3 limbed aeration and mixing assembly and a set of ‘bomb’ doors
down which the processed material drops as it moves from one level to the next.
Waste spends two days sealed in each level, its temperature being controlled between pre-set thresholds by the addition of air, agitation and the rate of extraction of compartment atmosphere through the bio-filtration system. After approximately 9 days the bio-waste fractions have been substantially stabilised and composted. The mixed stabilised material is unloaded and goes through a multi-stage segregation process, incorporating trommels, air-knives, ferrous and eddy current segregation.
Premier Waste Management even have podcasts for you to watch about the PARC system.
