HRS pasteurisation system helps Shanks achieve PAS 110 certification

Pasteurisation technology supplied by HRS Heat Exchangers has helped international waste-to-product business Shanks Group plc, gain PAS 110 certification for its Westcott Park anaerobic digestion (AD) facility in Buckinghamshire.

Publicly Available Specification 110 (‘PAS 110’) is a demanding industry specification which verifies the quality of digestate (the organic biofertiliser output from the AD process) and covers the product quality, standards for input materials and the management system for the AD process.

This important development, which was achieved in April this year, means that the digestate produced by Westcott Park is of a consistent high quality which can be sold and applied as an agricultural fertiliser. The facility also received a Certificate of Compliance by Organic Farmers & Growers Ltd, meaning that the digestate can be used by both conventional and organic farmers to provide nutrients and valuable organic matter to their crops.
