Green Chemistry: From Wastes to Value-Added Products (2nd Edition)

Dear Colleagues,

The predominant linear mentality that is maintained in modern society has only advanced the serious environmental crises, such as the rampant deposition of waste in our environment, the regulated accumulation in landfills, and the mismanagement of waste through incineration, resulting in harmful substances which are detrimental to both human health and ecosystems. An urgent paradigm shift towards circular thinking is imperative, in which the conventional concept of “waste” is dissipated, giving way to its reclassification as “raw material”. This transformative approach not only mitigates environmental degradation, but also promotes resource efficiency and sustainability. Adopting this ethic opens avenues for innovative recycling technologies and closed-loop systems, underpinning a sustainable future in which waste is no longer a burden, but rather a valuable asset in the resource ecosystem.

A previous edition of this Special Issue on “Green Chemistry: From Waste to Value-Added Products” has described different methods of waste recovery processes to produce value-added products. This second issue “Green Chemistry: From Wastes to Value-Added Products (2nd Edition)” aims to continue to cover advances in the development and application of processes in this field. Topics include, but are not limited to, the following:

• Production of medium and small chain fatty acids from organic waste;
• Production of bioplastics from waste;
• Production of biofuels and biogas from organic waste materials;
• Production of hydrogen from waste materials;
• Production of fuels from waste plastics by cracking, hydrocracking and pyrolysis;
• Recovery of monomers from plastic waste;
•  Application and optimization of pyrolysis processes for waste recovery (biowaste, MSW...);
• Biochar applications (in agriculture, biochar and carbon sequestration...).

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 submissions that pass pre-check are 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. Processes is an international peer-reviewed open access monthly 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 2400 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.
