This deliverable is number 3 of 3 in Work Package 3 and describes the findings and outputs from the technology system modelling work carried out by the consortium. It draws on the outputs from WP1 ? Waste Assessment and WP2 ? Assessment of EfW technologies. It combines the arising data from each work package into an economic, mass and energy model which takes into account the changing availability of wastes in the UK and aligns technology choices with the likely waste arisings.
