Presentation of PhD work
The treatment of municipal solid waste (MSW) has become a major problem in many countries, especially, where the population density is high and the landfill space is limited. MSW has caused a series of social, economic and environmental impacts and its treatment posed serious problems. Incineration is known to be a new strategy to dispose of these waste with as much as 90% volume reduction and without further problems such as leachate and odor. However, incineration requires high energy consumption and results in a large amount of fly and bottom ash waste. In addition, ash treatment remains unsolved. In fact, ash must be detoxified or decontaminated because of its significant concentrations of heavy metals, such as lead, chromium, copper, zinc, as well as organic pollutants such as dioxins. Therefore, his PhD aims to find an efficient way to solve these issues by producing original aggregate using municipal solid waste incineration ( MSWI) and other binders. This solution allows the disposal and reuse of these waste in an eco-friendly way.
