The ETI commissioned AEA to provide an up-to-date assessment of current development and demonstration activities in EfW technologies, including both Advanced thermal Treatment (ATT) and Anaerobic Digestion (AD) technologies This document is the Executive Summary of AEA’s review. It concludes that Advanced thermal Treatment and Anaerobic Digestion are at quite different levels of development with respect to the treatment of waste. It identifies four potential opportunities for disruptive or step-change innovations in the market: Biogas cleaning and compression (for gas grid or vehicle use) for Medium Scale AD plant applications generating around 300kW and 1500 kW of biogas (Type 2) applications Multi-stage AD plant for Type 2 applications Thermo-chemical pre-treatment of wastes to increase biodegradability of feedstock Single stageAD plant for dairy farms (Type 3)Overall, few noteworthy examples of ATT processes handling waste well for the production of energy were found, but there are many AD processes that are doing fine, and might, with more investment, do even better. This document is Appendix B1 (of 3) of the Energy from Waste UK Benefits Case (Deliverable 2 of 2 in Work Package 4).. Appendices B2 and B3 are the full reports for each technology family, and are separate documents. |
