This deliverable is number 2 of 3 in Work Package 1 and presents the initial results of waste sampling, including physical composition of waste materials and the detailed laboratory analysis. The report is intended to enable the reader to understand the main energetic waste flows over the initial 2 seasons of analysis of the project (November 2009 to January 2010 and February 2010 to May 2010). In all 4 seasons of sampling will be carried out. The information is based on the assessed sites only and at this stage only a preliminary attempt has been made to aggregate the derived results over the UK. The initial conclusions of the analysis undertaken for season 1 and 2 are presented in this report.
