Special Issue Information

Dear Colleagues,

Biomass will play a vital role in transitioning to a circular economy, which is an integral strategy to attain the Sustainable Development Goals (SDGs). Biomass resources such as agricultural and forestry residues, food wastes, or dedicated energy crops can be used as feedstocks within biorefinery schemes. At biorefineries, different thermochemical and biochemical processes allow the conversion of biomasses into valuable products such as biofuels, bioenergy, and other platform and specialty biochemicals. These bio-based products can replace other fossil-based products in the economy, potentially providing environmental benefits across different sectors.

This Special Issue aims to collect innovative research on state-of-the-art technologies, novel processes, and assessment tools to support the deployment of sustainable biorefineries. We welcome the submission of articles and reviews on topics including, but not limited to:

  • Valorization of biomass using green solvents.
  • Design of biorefining processes for energy, fuels, and platform chemicals.
  • Innovative techniques (e.g., green chemistry) for the extraction, separation and purification of bioactive compounds.
  • Characterization of extracts and the identification and potential uses of bioactive compounds.
  • Cascading biorefinery strategies for the integral valorization of biomass resources.
  • Techno-economic and environmental analysis of bio-based production systems.

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.

The development of a biorefinery is described based on rapid polishing of partially treated sewage with three different species of macrophytes in the recently developed SHEFROL® bioreactor which functions almost entirely on solar and gravitational energy, requiring no chemicals. It was seen that at a hydraulic retention time (HRT) of just 2 h, suspended solids, COD, BOD, total Kjeldahl nitrogen, soluble phosphorus, zinc, copper, nickel, and manganese are reduced to the extents of 92–95%, 76–78%, 77–81%, 56–61%, 60–66%, 43–46%, 45–48%, 30–35%, and 31–33%, respectively. The treated water meets the water quality standards set for the discharge into surface water bodies. M. quadrifolia was seen to be most effective of the three macrophytes, followed by P. stratiotes and S. molesta, as a sewage cleansing agent, but the difference in the performance of the macrophytes was only marginal, and not highly significant statistically (p ≥ 0.5). The paper also shows that it is possible to extract energy precursors in the form of volatile fatty acids (VFAs) from the harvested macrophyte biomass and then convert the biomass into organic fertiliser. All the steps associated with the closed loop circular biorefinery occur at ambient temperatures and pressures, requiring little consumption of energy and materials, and leaving negligible footprints.
