The use of thermal technologies for the recovery of value-added products from household solid waste: A brief review

Abstract The amount of household solid waste (HSW) has been significantly increasing due to a rapid population growth and economic development. HSW management is immensely sensitive and complicated problem not only in rapidly developing countries like Uzbekistan but also in developed countries with advanced economies.The accumulated waste has been causing a number of serious environmental problems such as release of the most dangerous greenhouse gases (CO 2 , N 2 O, CH 4 ) in the atmosphere which misbalance radiation in a planet’s atmosphere causing a global warming. However, this waste can be friendly in terms of its potential to be used as energy source. HSW into energy conversion technologies has been playing a vital rolein order to successfully address global challenges suchas fossil fuel dependency, emission control and waste management issues.The most promising technology for conversions can be performed using thermochemical processes (e.g., pyrolysis or gasification).These thermochemical technologies can be used to convert solid waste into liquid and gaseous fuels, and this has already been studied sufficiently by other researchers. This article recommends a novel concept for intensification of value-added solid and liquid products recovery from HSW using hydrothermal carbonization and plasma treatment.
