Historically, pyrolysis technologies occupied a niche, producing materials with useful chemical functionality from wood, by the continuous application of heat. In the 2181 century pyrolysis is promoted as an advanced technology for the extraction of heat from municipal refuse, at the same time as claiming sustainable and efficient credentials. This paper examines the concept of pyrolysis, and the potential for a phenomenon which demands energy to be considered as something which can be engineered to provide energy. Using literature review and case study methods, along with civil permit applications and experimental results, it shows that a pyrolysis plant for self-sustaining Energy from Waste is thermodynamically unproven, practically implausible, and environmentally unsound. A linkage between widespread commercial failures and a lack of focus on thermodynamic fundamentals is also identified, along with an environment of indifference or ignorance towards energy balances and sustainability when these technologies are presented, assessed and financed. Though proposals to build machines which violate physical laws is not new, in a modem context this phenomenon is found to be stimulated by competitive financial rewards. The situation presents a high risk to investors and has the potential to adversely impact on societal transitions to a more sustainable future.
