In the past decade the UK has had controversy over incinerating municipal solid waste (MSW), alongside efforts towards moving up the waste hierarchy. These pressures have offered opportunities for Advanced Thermal Treatments (ATTs), e.g. pyrolysis and gasification. Long ago gasifiers were designed to convert homogeneous feedstock, so the technology has needed significant development to treat MSW and recover more energy. In the past couple years, some contracts between UK local authorities and waste-management companies have included a gasifier, usually with an on-site MBT plant to remove recyclables and pre-treat the feedstock. Such facilities have been promoted as ‘not incineration’.
Questions: What are the prospects to improve and commercialise ATTs for MSW, to move up the waste hierarchy, and to take waste management beyond incineration? How do decision-makers compare various options for thermal treatment? Within an EPSRC project, the socio-economic study analysed such decision-making; the results will be discussed in the first part of this seminar. The overall project tested synergies between waste-conversion technologies; its experimental results will be discussed in the second part.
