TL;DR: In this article, the options of converting sewage sludge to energy and fuel via three main thermochemical conversion processes namely pyrolysis, gasification and combustion are reviewed, and various alternative approaches deserving further consideration, such as the incorporation of pre-processing and co-utilization, are discussed.

TL;DR: The compositions, characteristics and dehalogenation methods during the pyrolysis recycling process of WEEE plastics were reviewed in this paper and can, to some degree, avoid the problem of oil value decline due to the use of catalyst, but obviously, this strategy may increase the cost of whole recycling process.

TL;DR: The relationships between gas composition/char properties and pyrolysis temperature under high heating rate conditions were revealed and carbon skeleton shrinkage increased by more than 23% when the temperature increased from 600 to 1000°C.

TL;DR: In this article, the authors summarized the current techniques of brominated flame retardant (BFR)plastics recycling with a view to solving energy crisis and the environmental degradation of BFR-plastics.

TL;DR: In this article, a detailed characterization of five samples of different type of ashes, collected from two types of municipal solid waste incinerators located in Shenzhen (southern China), was carried out in terms of chemical composition, morphology, mineralogy and leaching behavior.
