Biorefinery Co-Products
Phytochemicals, Primary Metabolites and Value-Added Biomass Processing
Wiley Series in Renewable Resources
1. Edition March 2012
382 Pages, Hardcover
Handbook/Reference Book
Short Description
Part of the Wiley Series in Renewable Resources, this book is a comprehensive reference source devoted to the recovery of valuable phytochemicals from biomass. Following introductory chapters which discuss the concepts of phytochemicals and of biorefineries, the reader is presented with specific examples of phytochemicals that can be extracted from biorefinery-destined feedstock. The book concludes with chapters which discuss the uses of phytochemicals in the developing natural product industry, and phytochemical extraction from sustainability and compound separation perspectives.
Further versions
In order to successfully compete as a sustainable energy source, the value of biomass must be maximized through the production of valuable co-products in the biorefinery. Specialty chemicals and other biobased products can be extracted from biomass prior to or after the conversion process, thus increasing the overall profitability and sustainability of the biorefinery.
Biorefinery Co-Products highlights various co-products that are present in biomass prior to and after processing, describes strategies for their extraction , and presents examples of bioenergy feedstocks that contain high value products.
Topics covered include:
* Bioactive compounds from woody biomass
* Phytochemicals from sugar cane, citrus waste and algae
* Valuable products from corn and other oil seed crops
* Proteins from forages
* Enhancing the value of existing biomass processing streams
Aimed at academic researchers, professionals and specialists in the bioenergy industry, Biorefinery Co-Products is an essential text for all scientists and engineers working on the efficient separation, purification and manufacture of value-added biorefinery co-products.
