(2006). Characterisation of treated wastes to support an evidence base for sustainable waste management. Proc. Waste 2006: Sustainable Waste and Resource Management Conf., Stratford-upon-Avon, UK, 19-21 September 2006, 447-456.0-9539301-3-0http://www.waste2006.com/http://hdl.handle.net/1826/2563Defra must consider policies and strategies to manage environmental challenges such as climate change and sustainability. At a basic level the strategies need good quality data on waste characteristics. The dataset for UK wastes, in particular the new generation of treated wastes, is not fit for this purpose. This paper outlines the gaps in knowledge needed to underpin policy development and initial findings from a new project funded under Defra’s Waste and Resource Management Research Programme. The project team from WRc, Open University and Cranfield University aims to improve understanding of the characteristics of treated organic and inorganic wastes, methods of testing and knowledge of treatment process performance. Potential opportunities from the research are also described. New data will be collated into the presentation.enConference paper
