Dear Colleagues,

For many years, environmental biotechnology has engaged in the fight against climate change and has succeeded in improving the sustainability standards of multiple human activities. Within the current circular bioeconomy framework, new opportunities arise from the application of emerging environmental biotech innovations to existing industrial processes, as well as to the management of overabundant waste and residual side streams (e.g., agri-food waste, animal waste, excess sewage sludge). This Special Issue invites research papers, critical reviews and feature articles that critically examine biological resource recovery and valorization through processes such as carbon capture and utilization (CCU), nutrient recovery and upcycling or wastewater treatment and reutilization. To unlock their real circular bioeconomy potential, the investigated processes should be aimed at sourcing added-value products that can find real-life applications and that are appealing for the market. A non-exclusive list of such products comprises single-cell protein for feed and food applications, biofertilizers and biostimulants for agriculture, as well as bio-based polymers for renewable materials. Besides the mere scientific research aspects, the invited studies will have to also embrace multidisciplinary considerations and analyses of the environmental, economic and social implications of the proposed research and innovations.

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. Sustainability is an international peer-reviewed open access semimonthly 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.
