Special Issue "Heterogeneous Catalysts for the Valorization of Biomass Derived Compounds"
Deadline for manuscript submissions: 31 January 2024 | Viewed by 4460
The anthropogenic emissions caused by the use of fossil fuels prompt demand for sustainable renewable alternatives. Biomass plays an important role in mitigating climate change, as it is the most abundant renewable source of organic carbon available on Earth. It can be found in terrestrial agriculture, such as in forestry, food and other solid residues, or aquatic biomass, such as in the form of algae residues. The valorization of these residues is possible due to the components present therein, such as cellulose, hemicelluloses, lignin and starch. These components can be converted to important biofuels and chemicals, such as organic acids, furanic aldehydes, furanic ethers, levulinates, aromatics and amino acids with applications in several sectors of the chemical industry. Homogeneous catalysts can be very efficient in several conversion processes, but they present several drawbacks such as difficult recovery and separation from the target products, with increased costs. The use of multifunctional heterogenous catalysts is important to enhance the productivity of the processes and allow multiple steps to be carried out in only one reactor. Hence, the development of suitable heterogeneous catalysts for biomass valorization is crucial. This issue covers all aspects of heterogeneous catalysis applied to the valorization of vegetable biomass and derived compounds for producing useful chemicals, biofuels or fuel additives.

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. Molecules 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 2700 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.

Title: Autocatalytic oxidation of municipal biowaste

Abstract: Autocatalytic oxidation of municipal biowaste is performed in the presence a photosensitizer (PHTS) as reaction product, using water as solvent/reagent, solar light as energy source, and hydrogen peroxide and ozone as alternative auxiliary oxidants. The process allows obtaining biopolymers (BPM) for the production of bioplastics, biosurfactants (BPS) and other building blocks (BBB) molecules for the chemical industry. The expected environmental and economic benefits of the above process and products are discussed in comparison with other known technologies for the valorization of biomass derived compounds.
