Mercury release from municipal solid waste in the thermal treatment process

Adsorption Behaviors of H2S and CO2 on the Synergistic Removal of HCl and Hg0 in Pyrolytic Waste Plastic Gas on 4Ca-1Co/CA

“…However, organic solid wastes containing elements such as chlorine and mercury (such as polyvinyl chloride and biomass) would generate various pollutants such as HCl and gaseous mercury during pyrolysis. HCl would corrode equipment, pipelines, and valves, causing huge risk. , High Hg 0 concentrations could destroy aluminum compression and purification devices through metal embrittlement.…”

Sustainable Plasma Gasification Treatment of Plastic Waste: Evaluating Environmental, Economic, and Strategic Dimensions

“…Thermal plasma is used in waste processing, which is characterized by very high temperatures and energy densities. High-temperature plasma jets can be produced by passing an electric current through a gas . During high-temperature plasma heat treatment, the starting material is completely decomposed into simpler material compounds in a process called plasma gasification, which occurs in a partially oxidizing environment.…”

“…High-temperature plasma jets can be produced by passing an electric current through a gas. 26 During high-temperature plasma heat treatment, the starting material is completely decomposed into simpler material compounds in a process called plasma gasification, which occurs in a partially oxidizing environment. The organic partial conversion of solid feedstocks produces high-quality syngas that can be used as fuel for power generation or to manufacture chemicals.…”

Uncaptured mercury lost to the environment from waste electrical and electronic equipment (WEEE) in scrap metal and municipal wastes

“…For example, fluorescent lamps constituted about 20% of mercury input in the municipal solid waste in China and because of this contamination mercury emissions from incineration in waste-to-energy plants increased (Hu et al, 2018). Emission inventories such as those produced under the CLRTAP or Mercury Inventory Toolkit (UNEP, 2019) are limited in their assessment of these releases as they are not derived from primary fossil fuels (Dziok et al, 2022). These concerns are beginning to be addressed in Europe through tighter measures to control mercury emissions within the best available techniques documents for both the waste treatment and waste incineration sectors under the Industrial Emissions Directive (Joint Research Centre (European Commission) et al, 2019, 2018.…”
