The Renewable Energy Association (REA) has launched a best practice guide to help reduce plastics and other physical contaminants in feedstock for composting.
The Feedstock Quality Package, which is published by the REA’s Organics Recycling Group and supported by the National Association of Waste Disposal Officers and the Local Authority Recycling Advisory Committee, sets out guidance for composters and councils to work together to improve the quality of feedstock collected and delivered to composting sites.
The three-part package comprises a position statement outlining measures compost producers and waste suppliers can take to minimise problems arising from physical contaminants, an updated input specification template for garden wastes and commingled garden/food waste, and a visual assessment guide to help site operators identify whether a load requires rejection or cleaning up before it is shredded and composted.
Kiara Zennaro, REA senior technical officer, said: “By working collaboratively to improve feedstock quality, local government and the composting industry will be able to guarantee the production of quality composts, while reducing processing and disposal costs. Quality is imperative to secure markets for composts, maintain end users’ confidence in these products and maximise their value.”
The REA is also working with the Anaerobic Digestion and Bioresources Association and Environmental Services Association to put together a similar package for AD feedstock.
