This article discusses the use of olivine in the gasification of plastic waste. Olivine acts as a catalyst to reduce the hydrocarbon presence and increase the thermal efficiency of synthetic gases (syngas). Syngas is produced from plastics using a bubbling fluidized bed air-gasification process. A laboratory gasification plant for polyethylene pellets was used to measure the effect of olivine in carbon mitigation. The chemical stages of this mitigation process are described. The significance of developing new gasification technologies for waste management purposes is noted.

This investigation examined the predictors of the acceptance of waste incineration facilities. A survey was conducted of a random sample of the residents in two sites where an incinerator was planned (450 participants in Study 1 and 300 in Study 2). Attitudes towards the incinerator were mainly predicted by the perception of the risks as dread, positive expectancies about the project, trust in social actors involved in the process, perceived distributive justice, and distance of residence to the site. The relationship between distance of residence and attitude towards the incinerator was partially mediated by perceived risk, perceived justice, and expectations. As expected from the elaboration likelihood model, substantive peripheral cues were better predictors of attitudes for involved than for noninvolved dwellers. [ABSTRACT FROM AUTHOR]
