WRAP guidance on management of liners for food waste at AD sites

WRAP have published some industry guidance focused on dealing with household food waste at AD Facilities – Management of Liners. This guidance will help AD operators to limit the amount of plastic that ends up in digestate as a result of food waste caddy liners. 

WRAP has consulted with relevant stakeholders to produce guidance that will ensure food waste collection and treatment systems are more closely aligned. Standard Operating Procedures have been developed to assist AD operators in limiting the amount of plastic and compostable liners that end up in digestate. They include:
  • Contractual specifications
  • Pre-waste acceptance procedures
  • On-site waste acceptance procedures
  • Identification of contamination prior to treatment
  • Removal and management of contamination

There are also recommendations for increasing collaboration between those producing the waste, those collecting it, and AD operators; and for staff training to ensure that any measures introduced to improve the quality of food waste are sustained. 

The guide has been produced as part of the Food Waste Recycling Action Plan, an industry-led plan to improve the capture, supply and quality of household and commercial food waste.
