Resource Futures evaluated the performance of WRAP’s separate food waste collections trials, carried out in 19 local authorities in England and Northern Ireland. A high profile report was published by WRAP, along with six case studies examining particular aspects of the trials in greater depth.
Food waste is the largest part of the waste householders throw away, causing huge environmental damage and financial burden. Before WRAP ran their trials, separate food waste collections in the UK were few and far between. It was necessary to understand how separate collections would perform in a range of settings and using a variety of operational approaches.
On behalf of WRAP, we evaluated groundbreaking trials with 19 councils, collecting food waste separately for composting. Our job was to analyse the performance of the trials, in terms of weights collected, participation, set out and captures rates. We analysed attitudinal survey data to understand challenges in proving public behaviour and participation in the collections. In addition, we carried out several workshops with WRAP and the participating local authorities to draw out key practical lessons for implementing and managing separate food waste collections.
We analysed all performance data from the trials and produced a strong evidence base for predicting collection yields and participation rates for separate food waste collections in different settings. This resulted in the production of a high profile report detailing how the trials performed and providing guidance to councils across the UK on how to implement collections of food waste.
Since the guidance was published, numerous councils and practitioners have used the guidance to help them implement separate food waste collections. When planning how to collected food waste, local authorities need to understand how much food waste they are likely to collect and how many containers they will need to service in order to build a business case for implementation.
