…..And when does a waste cease to be a waste? Such simple questions to ask but often challenging to answer. There is an inherent conflict in waste managment legislation where on one hand there is a need to control wastes to protect human health and the environment and on the other hand the need to be more sustainable from preventing waste to adopting a circular economy approach.
Last week saw the Enviroment Agency publish a series of research reports to characterise 15 non-waste materials as comparators for waste-derived materials. This included construction, and soil improvement materials applied to land as shown in the table below.

- natural limestone aggregate
- non-waste wood used in construction and manufacturing
