TL;DR: In this article, a systematic analysis of organic waste sorting and recycling/composting practices in several countries: the UK, US, Japan, and China is presented, focusing on their generation and control strategies, in an effort to identify barriers hindering waste composting.

TL;DR: Analysis of lab-scale artificially weathered and 10-year landfilled bottom ash samples revealed that secondary mineralization/alteration of the bottom ash constituents principally carbonation and glass evolution substantially decreased the potential risk of the heavy metals to the surrounding environment.

TL;DR: Leaching experiments indicated that the mobility of heavy metals in the landfill was generally low under normal neutral conditions, however, release of heavy metal release can be increased greatly when medium conditions become more acidic and aerobic.

TL;DR: This work investigated the phase transformation of the collected bottom ash particles, neoformation processes as well as the behavior and distribution of certain heavy metals in the neoformed phases using optical microscopy, SEM-EDX, and bulk examinations.

TL;DR: The experimental results showed the total Cl content in the MSWI bottom ash was reduced by 55.46% after a 4-h heating process at 1000°C, and the removal of the soluble Cl by the thermal process was found to be more effective.
