Special Issue Information

Dear Colleagues,

This Special Issue has as its main goal to discuss the current situation and perspectives for waste-to-energy using MSW, as well as those for wastes and the circular economy, focusing mainly on developing and least-developing countries. Current situation, synergies, existing barriers, and perspectives for WtE and the circular economy should be our main subjects.

The environmental and social benefits of WtE for the circular economy are well known, and they have been extensively discussed before. In the current proposal, the idea is to go more in depth, considering the interface of WtE with the bioeconomy, mainly in developing countries.

In fact, as the figure below shows, MSW collection and treatment, as well as WtE systems, have already become a reality, though mostly in high and upper-middle income countries.

The use of WtE systems has also been growing worldwide, as shown in the figure ahead, but it is well known that this is unfortunately not the case in developing and least-developing countries, where MSW collection is reduced, and adequate treatment is almost impossible in many cases.

In addition, the figure below illustrates the current situation of MSW disposal worldwide, showing the existing difficulties related to an adequate disposal process.

Therefore, the main objective of this Special Issue is to discuss this in the context of developing and least-developing countries, and we are inviting high-quality submissions on this topic. Please note that we expect the Special Issue to be completed by December 2021. I look forward to receiving your contributions.

Sincerely yours

The growth of the economy in urban centers is invariably accompanied by an increase in human activities and environmental interference, mainly related to waste generation. Due to the nature of these activities, large volumes of varied waste are generated daily without the establishment of compatible and adequate collection, logistics, and final disposal systems, bringing relevant impacts to society on health, the environment, and the economy itself. In Brazil, in 2019 alone, almost 30 million tons of MSW were not collected and the total collected, of approximately 44 million tons, went to landfills, with little or no energy use. There is therefore a great opportunity for energy use using this source, aiming not only to adapt to current legislation, but also to reduce GHG emissions, reduce the population’s exposure to sanitary landfills and open air, and use the energy contained in these wastes. The purpose of this study is to analyze the main conditions and challenges of current technologies for harnessing the energy potential of biomass from urban solid waste (USW) to enable the insertion of mini thermal plants connected to distributed generation.
