We compost over 400,000 tonnes of green and organic wastes each year from local authorities and businesses of all sizes. 

We manage and operate a number of facilities that, under strict control procedures, transform organic wastes to produce high quality compost.

Windrow Composting uses garden waste - grass cuttings, leaves, weeds and hedge trimmings - from Household Waste Recycling Centres (HWRCs) and kerbside collections. Over 12 weeks it is shredded, mixed and placed into huge windrows, or elongated piles. The material is turned regularly to let oxygen circulate. Bacteria break down the material to produce heat which transforms and sanitises the product, turning it into rich, dark compost. Once the material is sorted and shredded, it is processed in an enclosed building where optimum temperatures and oxygen supply are maintained to accelerate the composting process.

We also operate a number of In-Vessel Composting (IVC) facilities in partnership with local authorities in the UK. An IVC is essentially like a home compost bin, but on a much larger scale. It harnesses the natural composting process, in enclosed tunnels to accelerate the cycle to recycle mixed organic garden and food waste into a compost product. The product is screened and graded and can then be used in horticulture and agriculture as a soil improver. 

We are an experienced compost producer and much of our Revive compost is certified to the national BSI PAS 100 quality assurance standard, accredited by the Renewable Energy Association's Organics Recycling Group (ORG). 

We produce Revive soil conditioner compost from garden waste that has been used to win medals and awards at the Chelsea and Hampton Court Flower Shows. Our Revive compost can also be used for a range of applications and end markets including horticulture, agriculture, sports facilities, landscaping and domestic gardening. 

Each site operates under the highest quality, environmental, energy efficiency, and health and safety standards – certified to ISO 9001, ISO 14001, ISO 50001 and OHSAS 18001 respectively.
