## Description

This project aims to improve our knowledge of the material composition of residual municipal waste by obtaining estimates of its material composition at residual end-of life treatment sites over a 12-month period \(representative of the 2024 calendar year\), estimates of the material composition and origin split of waste that has been identified as a chapter 19 waste code, and the biodegradability of municipal waste sent to landfill\. The project should account for seasonality in material composition or be able to robustly defend why seasonality should not be a consideration with recent \(within the last five years\), high-quality \(peer-reviewed or agreed as robust by Defra analysts\) published evidence\.
