A producer of quality compost for the mushroom industry since 1988, the Agricultural Supply Company (ASC) owns and operates a six hectare site, formerly a limestone quarry, in Sunhill, Gloucestershire.

One of only three of its kind in the UK, ASC employs 17 people and invests around £450,000 per year into the local economy. ASC's state-of-the-art 'in-vessel' composting system represents a capital investment of more than £5million and features stainless steel, computer controlled and vented tunnels – some of the most technically advanced in the composting industry and operating to rigorous performance standards.

With the aim of diversifying its business, against a backdrop of an urgent need to divert biodegradable household waste from landfill sites, ASC is currently in the process of putting forward a new, change of use planning application to Gloucestershire County Council.
