Platform Chemical Biorefinery: Future Green Chemistry provides information on three different aspects of platform chemical biorefinery. The book first presents a basic introduction to the industry beneficial for university students, then provides engineering details of existing or potential platform chemical biorefinery processes helpful to technical staff of biorefineries. Finally, the book presents a critical review of the entire platform chemical biorefinery process, including extensive global biorefinery practices and their potential environmental and market-related consequences.

Platform chemicals are building blocks of different valuable chemicals. The book evaluates the possibility of renewable feedstock-based platform chemical production and the fundamental challenges associated with this objective. Thus, the book is a useful reference for both academic readers and industry technical workers. The book guides the research community working in the field of platform chemical biorefinery to develop new pathways and technologies in combination with their market value and desirability.

Offers comprehensive coverage of platform chemicals biorefineries, recent advances and technology developments, potential issues for preventing commercialization, and solutions Discusses existing technologies for platform chemicals production, highlighting benefits as well their possible adverse effects on the environment and food security Includes a global market analysis of platform chemicals and outlines industry opportunities Serves as a useful reference for both academic readers and industry technical workers

Selenium contamination of air, aquatic environments, soils and sediments is a serious environmental concern of increasing importance. Selenium has a paradoxical feature in bringing about health benefits under the prescribed level, but only a few fold increase in its concentration causes deleterious effects to flora and fauna, humans and the environment. Environmental Technologies to Treat Selenium Pollution: principles and engineering:- presents the fundamentals of the biogeochemical selenium cycle and which imbalances in this cycle result in pollution. - overviews chemical and biological technologies for successful treatment of selenium contaminated water, air, soils and sediments.- explores the recovery of value-added products from selenium laden waste streams, including biofortication and selenium based nanoparticles and quantum dots. This book may serve both as an advanced textbook for undergraduate and graduate students majoring in environmental sciences, technology or engineering as well as a handbook for tertiary educators, researchers, professionals and policy makers who conduct research and practices in selenium related fields. It is essential reading for consulting companies when dealing with selenium related environmental (bio)technologies.

This book presents an introduction to biohydrogen production and the recent advances and developments of the cleanest biofuel produced from bioresources.Biohydrogen has the highest energy content relative to weight and burns cleanly – generating just water. It is the best choice for fuel cells, where it generates electricity directly, in its reaction with oxygen. Biohydrogen occurs naturally as part of digestive gases from mammals and can be produced in specially designed anaerobic biodigesters, or through photocatalysis with microalgae. The gas is also easy to purify and use. The economic production of biohydrogen is still full of challenges: From the efficient and rapid conversion of the substrate to storage, transportation, and safe use, there are several aspects that need to be developed.Research in this field is addressing the issue of efficient large-scale production from several directions: Substrate pretreatment to enhance digestibility, metabolic networks analysis, microbial diversity and succession to highlight constraints in production, bioreactor, and downstream design to improve throughput and reduce costs, to name a few.The ideas and technologies presented in this book contribute to achieving the UN Sustainable Development Goal 7: Affordable and Clean Energy.The book is written for researchers and students interested in biorefinery and biofuel technologies.
