Special Issue Information

Dear Colleagues,

The waste-to-energy sector represents a major opportunity to improve the waste cycle, include circular economy principles and reduce the environmental impacts associated with waste management practices. This sector has become even more important during the SARS-CoV-19 pandemic with increased waste from hospital masks and gloves and other health-related items. The energy sector in general could also benefit from the integration of waste-to-energy in the energy mix.

The valorization of wastes (municipal, industrial, raw materials, sludge, etc.), their reuse and the possibility of generating energy from their disposal represents a more practical and potentially sustainable path to reducing pressures on landfill and decreasing the environmental impacts associated with these forms of waste products.

The potential for using waste at its end-of-life in energy production is increasingly being investigated. This Special Issue will look at the many issues facing successful waste to energy production, including the role of waste distribution, environmental and economic efficiency, the variety of waste-to-energy technologies being developed and the policy approaches being considered to increase interest in this developing sector. This issue will include a multi-disciplinary review of the challenges and benefits of international waste-to-energy production—the challenges and the opportunities.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Recycling is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Biosolids’ use in agriculture is an example of industrial symbiosis. The application of biosolids (BS) in agriculture is considered one of the most sustainable sewage sludge (SS) management options, but the quality of biosolids has to meet certain requirements regarding the characteristics of the sludge, those of the land and of the type of crop. Web of Science database has been used to search for the relevant literature. The review of studies undertaken in order to determine the economic effects of the use of biosolids in agriculture shows, in the majority, an increase in crop yield and the reduction in costs, due to the reduction in the requirements for the application of chemical or synthetic fertilizers. If the entire sewage sludge production in Romania for 2019 had been used as fertilizer, the estimated cost reduction for farmers would have been almost 3 million Euros—considering the 230.59 thousand tons of dry matter produced in 2019. The estimated savings for 2019 of the sewage and water utilities, if the sewage sludge had been used in agriculture instead of depositing it at the landfill, would have been about 3.9 million Euros. However, the limits of the symbiosis are due to the size of the farms, the type of plants cultivated, pH, slope inclination, heavy metal content and social acceptance. It is impossible to use all the sewage sludge in agriculture, but these figures are a good estimation of the economic effects. Full article
