Report – Tackling contamination: Improving the quality of household recycling in London

ReLondon ran a variety of projects with individual London local authorities looking at how to improve the quality of recycling being collected from households. 

These projects, their methodology and their results, are described in this report.

About the Tackling contamination project

Contamination in the household recycling stream is one of the most common issues London’s local authorities face with their household collection services, affecting budgets, recycling performance and the quality of recyclate. 

In this research project, ReLondon worked with London’s authorities to help them understand the true cost of reactively dealing with contamination in recycling at the kerbside and in flats, and tested interventions to reduce contamination and improve the quality of the recycling being collected.
