Global awareness of environmental issues has resulted in the emergence of economically and environmentally friendly bio-based materials free from the traditional side effects of synthetics. This book delivers an overview of the advancements made in the development of natural biorenewable resources-based materials, including processing methods and potential applications in green composites. Biorenewable polymers are a special class of natural material found in nature, such as natural fibers, wheat straw, rice husk, and saw dust. In addition to offering renewable feedstocks, natural biorenewable materials are compostable, recyclable, edible, and more energy efficient to process than plastic.
Green Composites from Natural Resources covers various kinds of cellulosic biofibers, such as:
hemp fibers
jute
saccaharum cilliare fibers
pine needles
grewia optiva fibers
sisal fibers
eulaliopsis binata
flax fibers
coconut fibers
eulaliopsis binata
baggase fibers
rice husk
saw dust
wood flour
straw
With scopes for the utilization of natural resources-based materials as potential replacements for traditional petroleum feedstocks on the rise, more scientists and researchers are exploring new composite materials based on biorenewable resources. This book provides information on more eco-friendly and sustainable alternatives to synthetic polymers and discusses the present state and growing utility of green materials from natural resources.

A comprehensive introduction to the design, synthesis, characterization, and catalytic properties of nanoporous catalysts for the biomass conversion
With the specter of peak oil demand looming on the horizon, and mounting concerns over the environmental impact of greenhouse gas emissions, biomass has taken on a prominent role as a sustainable alternative fuel source. One critical aspect of the biomass challenge is the development of novel catalytic materials for effective and controllable biomass conversion. Edited by two scientists recognized internationally for their pioneering work in the field, this book focuses on nanoporous catalysts, the most promising class of catalytic materials for the conversion of biomass into fuel and other products.
Although various catalysts have been used in the conversion of biomass-derived feedstocks, nanoporous catalysts exhibit high catalytic activities and/or unique product selectivities due to their large surface area, open nanopores, and highly dispersed active sites. This book covers an array of nanoporous catalysts currently in use for biomass conversion, including resins, metal oxides, carbons, mesoporous silicates, polydivinylbenzene, and zeolites. The authors summarize the design, synthesis, characterization and catalytic properties of these nanoporous catalysts for biomass conversions, discussing the features of these catalysts and considering future opportunities for developing more efficient catalysts. Topics covered include:
Resins for biomass conversion
Supported metal oxides/sulfides for biomass oxidation and hydrogenation
Nanoporous metal oxides
Ordered mesoporous silica-based catalysts
Sulfonated carbon catalysts
Porous polydivinylbenzene
Aluminosilicate zeolites for bio-oil upgrading
Rice straw Hydrogenation for sugar conversion
Lignin depolymerization
Timely, authoritative, and comprehensive, Nanoporous Catalysts for Biomass Conversion is a valuable working resource for academic researchers, industrial scientists and graduate students working in the fields of biomass conversion, catalysis, materials science, green and sustainable chemistry, and chemical/process engineering.

The magneto luminous chemical vapor deposition (MLCVD) method is the perfect example of the "front-end green process." It employs an entirely new process that expends the minimum amount of materials in gas phase, yields virtually no effluent, and therefore requires no environmental remediation. Unlike the "back-end green process," which calls for add-on processes to deal with effluent problems, the newer MLCVD approach is a completely different phenomenon that has never been adequately described, until now.
Dispelling previous misconceptions and revealing new areas for investigation, Magneto Luminous Chemical Vapor Deposition describes the key process of dielectric breakdown of gas molecules under the influence of a magnetic field. It emphasizes behavioral distinctions between molecular gasses that cause plasma polymerization (such as methane and trimethylsilane) and mono-atomic gases (e.g., helium and argon) when dealing with the dielectric breakdown of the gas phase under low pressure. The author also reveals his minimum perturbation theory of biocompatibility. This is based on the realization that nanofilms prepared using MLCVD have unique, stable interfacial characteristics necessary to achieve a surface that can be tolerated in various biological environments.
The author presents alternating views based on NASA's recent discovery that a magnetic field burst from the earth triggers the inception of the aurora borealis. Detailing similarities between this phenomenon and the inception of the magneto luminous gas phase described in this book, the author proposes that proof of the one occurrence could shed light on the other. Expanding on the author's previous works, this book introduces new discoveries, highlights the newfound errors of previous assumptions, and juxtaposes many cutting-edge alternative views and anomalies associated with the field.

The "greening" of industry processes - i.e., making them more sustainable - is a popular and often lucrative trend which has seen increased attention in recent years. Green Chemical Processes, the 2nd volume of Green Chemical Processing, covers the hot topic of sustainability in chemistry with a view to education, as well as considering corporate and environmental interests, e.g. in the context of energy production. The diverse team of authors allows for a balance between these different, but interconnected perspectives.
