Thermal treatment involves the application of heat to treat and decompose waste materials through different approaches ( Sivaramanan, 2013). Meththika Vithanage, in Handbook of Electronic Waste Management, 2020 7.2.3 Thermal treatment The results of this study seem to justify emphasis on the role of iron and clay minerals in thermally treated soil and on the conditions of thermal treatment which affect the behaviour of these constituents in soils. However, further work is necessary to determine the capabilities and limitations of these technologies for soils contaminated with both heavy metals and organic pollutants. The results presented in this paper and other work suggest that thermal technologies in the intermediate temperature range offer an opportunity to destroy simultaneously organic contaminants and to immobilize heavy metals in soil in one unit operation. In the present study the effects of thermal treatment on heavy metal leaching from soil have been examined. Thermal treatment also alters the physical and chemical properties of the soil, and thus affects the leachability of co-contaminants such as heavy metals. Average operating temperatures of commercial soil treatment systems generally vary between 500 and 650☌. Thermal treatment at intermediate temperatures is widely considered as an effective technology to remove organic contaminants from soil by volatilization and/or destruction. van Hasselt, in Studies in Environmental Science, 1997 Abstract More information about waste prevention programmes is available in individual country/region fact sheets.C. This is also likely to affect national target setting and indicator development. The report also raises data quality issues, and highlights that changes in waste classification and definition of hazardous waste cause reporting and interpretation problems and may affect the accuracy and comparability of national data. Prioritisation at the EU level is one of the drivers for better prevention at national or regional levels, the report says. However, prevention of hazardous waste appears to have lower priority than management aspects, and limited financial support. Most of the measures are linked to curbing production and including bans on toxic materials. More than half of the reviewed waste prevention programmes include measures to reduce the generation of hazardous waste. Total hazardous waste generation has increased slightly since 2008, according to the report. The predominant types of hazardous waste were mineral and solidified wastes, chemical and medical wastes, with the waste management, construction, mining and quarrying, and household sectors as the top sources. It provides an overview of waste prevention objectives, targets, indicators, and measures.Īt a reported 100 million tonnes, hazardous waste accounted for close to 4% of the 2.5 billion tonnes of waste generated across the European Union in 2012. The assessment looks at current trends in the amounts of hazardous waste generated both in Europe and in individual countries, based on the latest data available. This year’s review focuses on the prevention of hazardous waste that is one of the priorities of environmental policies in Europe. The EEA report ‘ Prevention of hazardous waste in Europe – the status in 2015,’ is the third annual review of waste prevention programmes done by the EEA.
