Biomass Treatment and Pyrolysis Processes

Dear Colleagues,

The treatment of biomass treatment and the pyrolysis process are important aspects in the context of waste management and energy production. Biomass is organic material that is produced by living organisms. Biomass treatment involves various methods to convert it into useful products, including energy, nutrients or raw materials. Basic biomass treatment methods include:

Composting: The process of breaking down organic matter by microorganisms in the presence of oxygen, resulting in the production of compost that can serve as a natural fertilizer.

Fermentation: This is a biological process in which microorganisms (bacteria, yeasts) break down organic matter, producing alcohols, gases and other products. For example, methanation is fermentation that produces methane that can be used as energy.

Gasification: This invovles the treatment of biomass at high temperatures in the presence of limited oxygen, resulting in the production of synthetic gas (gasification), which can be used for energy production.

Modern technologies: This includes hydrolysis, hydrothermal carbonization and biodiesel production.

Pyrolysis is a thermal process that aids the decomposition of organic matter in the absence of oxygen or at very low concentrations of oxygen. It usually takes place at high temperatures (300–900°C). The basic components of pyrolysis are as follows:

Solids (Char): Thhis is the residue after pyrolysis that can be used as carbon material in various industries or as a soil improver.

Liquid components (pyrolysis liquid): These can contain a wide range of chemicals that can be further processed into various chemical products or as biofuel.

Gaseous products (pyrolysis gas): These contain methane, hydrogen, carbon dioxide and hydrocarbons. These gases can be used as a source of energy or as raw materials in the chemical industry.

Pyrolysis is used to process different types of waste, including organic waste and plastic materials, and can be useful in the context of sustainable waste management and energy production. Understanding these processes is important to understanding how we can effectively manage resources and waste in our environment.

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.
