Measurement and Modelling of Waste Composition in England

Defra wishes to update its data on the composition of mixed waste and use the updated information, as well as wider insights, to develop a predictive model. The waste composition fieldwork will cover mixed municipal and non-municipal wastes from up to 50 waste and recycling streams. Representative samples of waste from each stream will be sampled and sorted into materials/items using a category list supplied by Defra. Each material category sampled and sorted will be weighed. Data will be scaled up to tonnages using the EWC/LoW codes. A model will be developed using this data and a package of work investigating the drivers of waste composition.
