Waste management firm Donarbon officially opened its new £4.5 million in-vessel composting plant, which forms part of its 28-year PFI contract with Cambridgeshire County Council to manage the countys household waste.
Located at its Waterbeach site, the new IVC plant designed and turn-key installed by technology provider Wasteology Systems, will take the countys mixed kitchen and garden waste that is collected at kerbside. It replaces a system that had been in place at Donarbons waste park since 2001.
Donarbon managing director Mark Davenport said: We are very pleased with the progress that has been made in developing these new facilities to treat Cambridgeshires waste to ensure that as little is sent to landfill as possible. We have been impressed with the operation of our existing Wasteology in-vessel plant and this new composting facility will ensure that green waste is properly treated so that the County Council meets all its landfill diversion and recycling targets.
The composting plant will initially treat over 75,000 tonnes of organic waste each year but has been built to take account of Cambridgeshires predicted population increase of 100,000 during the course of the PFI contract.
In-coming waste will be shredded and then composted inside enclosed concrete clamps at temperatures over 60ºC for two weeks, followed by six weeks of maturation, to produce around 40,000 tonnes of final compost. This will meet PAS 100 standard and will mainly be used by local farmers, residents and allotment holders.
Cambridgeshire County Council councillor Tony Orgee called the plant a fantastic addition to the waste facilities the county was building and one that would further improve the countys recycling performance nationally.
