Value-added biofuels

There is a new McCauley on the scene in this new millennium. Brad McCauley finished his education at Kansas State University in 2001. He has acquired land and equipment in Doniphan County. While the previous generations of his family must be part of his desire to return to his roots, Brad knows that the wonder of agricultural technology for him is only beginning. A new twist for the McCauley s is their investment in value-added agriculture, including both biofuels and food.

Drs. Martin Koller and Gerhart Braunegg suggest that facilities for the production of biopolymers, biofuels and biochemicals should be integrated into existing production lines, where the feedstock directly accrue as waste streams, to save costs on transportation. They point out that the utilization of waste streams for production of value-added products not only enhances the economics of such products, but also provides the industry with a strategy to overcome disposal problems. 

Currently, lignin is being utilized as a low grade boiler fuel, but several studies have been done to convert lignin to value-added products. These efforts are beneficial for biofuel production, whereas less attention has been paid to the separation of lignin. Main pathways for the utilization of lignin are ...

Pyrolysis is a thermochemical conversion option that can play an important role in hybrid biorefrnery concepts because it offers a flexible way to convert biomass and/or biomass residues into (a precursor for) value-added chemicals and products that enhance the profitability of the biorefrnery. Separation/purification/upgrading of pyrolysis oil into biofuels and/or individual chemicals is challenging and poses a broad area of research that may require the development of a whole new type of chemistry, specifically devoted to the physicochemical characteristics of biomass pyrolysis oils.

Industrial processes cmivert low-value carbon into high value-added products. To be economically viable, the cost of the overall bioprocess must be significantly less than the selling price of the product. Many variables contribute to bioprocess costs, but for bulk biochemicals such as biofuels and industrial chemicals (which many isoprenoids are used for), the price of the feedstock is the primary cost driver (Rude and Schirmer 2009 WUlke and Vorlop 2008). Currently, carbohydrates from plant biomass are the most important carbon feedstock for fermentation. Plants accumulate simple sugars, cellulose or lipids, which bacteria can convert into energy, biomass and products. Popular model organisms exploited in industry (such as... 

With the growing industrial interest in the production of biofuels, the most important areas that need attention and research seem to be (i) scale-up, (ii) cost efficiency, (iii) better fuel properties, (iv) norms and standards for producers and end-users, (v) environment health and safety issues in biomass io el handling, transportation and usage, (vi) encouragement to implement thermo-chemical processes and applications, (vii) efficient utilization of byproducts for value-added chemical or material production, and (viii) information dissemination. The biomass conversion process can be economically viable if used in an integrated manner for generation of other marketable co-products in addition to the primary biofuel product, thus contributing to sustainable development.
