Waste Biorefinery Technologies for Sustainable Development: Volume 2: Biological Processes

Waste Biorefinery Technologies for Sustainable Development: Volume 2: Biological Processes deals with the intersection of circular economy principles and biorefinery innovation, exploring how biorefineries can play a central role in closing the loop of resource use and promoting sustainable development. Through a comprehensive examination of circular economy concepts and biorefinery technologies, it illustrates how waste streams can be valorized and transformed into valuable products through efficient and sustainable processes. From organic wastes to agricultural residues and industrial by-products, it covers how diverse biomass feedstocks can be utilised within circular biorefinery systems to produce bioenergy, biochemicals, biomaterials, and bioplastics. The volumes cover the basic components of biorefineries and various approaches required for the valorization of versatile feedstocks which make an indispensable resource for (under)graduate students. The discussion of role of biorefineries in addressing global challenges such as climate change and resource depletion, current research trends, and future directions offers valuable guidance for researchers seeking to deepen their understanding and identify opportunities for further investigation. Volume 2 of this two-volume set deals with biological processes, and includes biochemical paths for converting biomass into bioproducts and biofuels, model refinery processes, recent trends and future prospects of circular biorefinery and their life cycle analysis, and future perspectives.

Dr. Ponnusami is at present working as Associate Dean in the School of Chemical and Biotechnology, SASTRA Deemed University, India. He did the doctoral research on textile effluent treatment at SASTRA Deemed University, India. His post-doctoral research includes wastewater treatment by physico-chemical treatments, lignocellulose degradation, bioprocessing for the production of enzymes and microbial polysaccharides, and biodiesel production. Towards achieving the goals of sustainable development his team is exploring the uses of green methods in biorefining of biomass. In particular, bioconversion of biomass into microbial exopolysaccharides such as levan, xantham gum, dextran, cellulose that are suitable for food and medical treatments are investigated. As far as renewable fuels are concerned we mainly work on process development for biodiesel and bioethanol from various agricultural and industrial waste products. The group is interested in developing chemical and biocatalysts for above-mentioned conversion processes. Prof. Ponnusami is included in the list of top 2% highly cited researchers’ published by Elsevier, consecutively for the past two years (2021 and 2022).
