Algae Based Polymers, Blends, and Composites


Book Description

Algae Based Polymers, Blends, and Composites: Chemistry, Biotechnology and Material Sciences offers considerable detail on the origin of algae, extraction of useful metabolites and major compounds from algal bio-mass, and the production and future prospects of sustainable polymers derived from algae, blends of algae, and algae based composites. Characterization methods and processing techniques for algae-based polymers and composites are discussed in detail, enabling researchers to apply the latest techniques to their own work. The conversion of bio-mass into high value chemicals, energy, and materials has ample financial and ecological importance, particularly in the era of declining petroleum reserves and global warming. Algae are an important source of biomass since they flourish rapidly and can be cultivated almost everywhere. At present the majority of naturally produced algal biomass is an unused resource and normally is left to decompose. Similarly, the use of this enormous underexploited biomass is mainly limited to food consumption and as bio-fertilizer. However, there is an opportunity here for materials scientists to explore its potential as a feedstock for the production of sustainable materials. - Provides detailed information on the extraction of useful compounds from algal biomass - Highlights the development of a range of polymers, blends, and composites - Includes coverage of characterization and processing techniques, enabling research scientists and engineers to apply the information to their own research and development - Discusses potential applications and future prospects of algae-based biopolymers, giving the latest insight into the future of these sustainable materials




Polytrimethylene Terephthalate Production - Cost Analysis - PTT E11A


Book Description

This report presents a cost analysis of Polytrimethylene Terephthalate (PTT) production from terephthalic acid and propanediol. The process examined is similar to Degussa (now Evonik) process. This report was developed based essentially on the following reference(s): (1) US Patent 7223830, issued to Zimmer in 2007 (assigned to Lurgi Zimmer GmbH in 2008) (2) EP Patent 0859020, issued to Zimmer and Degussa (now Evonik) in 2006 (3) US Patent 68007, issued to Zimmer and Shell in 2004 (assigned to Lurgi Zimmer GmbH in 2008) Keywords: 1,3-Polypropylene Terephthalate, TPA, PDO, Dimethyl Terephthalate, DMT




Toxicity Testing in the 21st Century


Book Description

Advances in molecular biology and toxicology are paving the way for major improvements in the evaluation of the hazards posed by the large number of chemicals found at low levels in the environment. The National Research Council was asked by the U.S. Environmental Protection Agency to review the state of the science and create a far-reaching vision for the future of toxicity testing. The book finds that developing, improving, and validating new laboratory tools based on recent scientific advances could significantly improve our ability to understand the hazards and risks posed by chemicals. This new knowledge would lead to much more informed environmental regulations and dramatically reduce the need for animal testing because the new tests would be based on human cells and cell components. Substantial scientific efforts and resources will be required to leverage these new technologies to realize the vision, but the result will be a more efficient, informative and less costly system for assessing the hazards posed by industrial chemicals and pesticides.




Polytrimethylene Terephthalate Production - Cost Analysis - PTT E31B


Book Description

This report presents a cost analysis of Polytrimethylene Terephthalate (PTT) production starting from raw sugar and terephthalic acid. The process examined combines a process similar to DuPont process for generating propanediol and a process similar to Degussa (now Evonik) process for producing PTT. In this process, raw sugar (sucrose) is diluted and sucrose is hydrolyzed into glucose and fructose (invert sugars). The invert sugars are then fermented to produce Propanediol. This report was developed based essentially on the following reference(s): Keywords: 1,3-Polypropylene Terephthalate, TPA, Dimethyl Terephthalate, DMT, Bio-PDO, Trimethylene Glycol, PTT, Aerobic Fermentation
