||This deliverable forms part of Deliverable 2.2 in Work Package 2 and provides information on the thermal waste material conversion rig scale testing. The testing programme reviewed in this summary report was originally intended fill in gaps in available data in the public domain relevant to the technologies which could be employed at each stage of an advanced energy from waste system. However, it was found that only very limited suitable data were available on the operation of Gasification technologies using the mixed wastes, and so it was necessary to carry out a more fundamental study to determine the suitability of these technologies for use with highly variable mixed waste feedstocks.
For reliable system operation, it is essential to have an understanding of the properties of the fuel gases produced and their contaminants, as well as information other process products/residues and any operational problems which would need to be overcome. The novel test work conducted for the ETI Energy from Waste (FRP) project has provided valuable insight into the use of these technologies with mixed waste streams and empirical data to inform the development of computer-based models of advanced waste processing technologies.
The findings from the testing programme, in relation to the processing and gas utilisation technologies, reinforce the well-known critical nature of gas cleaning in enabling successful utilisation of the fuel gases produced in high efficiency systems. Although not a distinct area of investigation within the current project, it is expected that the key development opportunities required to enable the efficient use of waste materials would be in the area of gas cleaning, as further detailed in report 3.3 of this project.
