The main feedstocks for bioethanol are sugarcane (Saccharum officinarum) and maize (Zea mays), both of which are C 4 grasses, highly efficient at converting solar energy into chemical energy, and both are food crops. As the systems for lignocellulosic bioethanol production become more efficient and cost effective, plant biomass from any source may be used as a feedstock for bioethanol production. Thus, a move away from using food plants to make fuel is possible, and sources of biomass such as wood from forestry and plant waste from cropping may be used. However, the bioethanol industry will need a continuous and reliable supply of biomass that can be produced at a low cost and with minimal use of water, fertilizer and arable land. As many C 4 plants have high light, water and nitrogen use efficiency, as compared with C 3 species, they are ideal as feedstock crops. We consider the productivity and resource use of a number of candidate plant species, and discuss biomass 'quality', that is, the composition of the plant cell wall.Byrt CS, Grof CPL, Furbank RT (2010) C 4 plants as biofuel feedstocks: Optimising biomass production and feedstock quality from a lignocellulosic perspective.

“…Due to these limitations, industries are pushing their plants to run on higher DS (dry solids) from 15-20 % to 25-35 % to save water and save up to 40-50 % energy consumption. In this process, the maximum backset or thin slop is recycled through liquefactions (Pohit et al 2009 ;Grafelman and Meagher 1995 ;Gohel and Duan 2012a ). The use of concentrated dry solids requires appropriate processes for plant optimization depending on the feedstock.…”

This chapter reviews recent advances in technology developments in biorefi nery industries through enzymatic approaches where various starchy materials have been used as feedstock for biofuel and various syrup productions. It further discusses the enzymes discovery, industrial challenges, and how enzymatic-based approaches help different industries to develop environmentally sustainable and cost-effective solutions by making industrial process into more simplifi ed without compromising the product and by-product yields and their qualities.

“…Consider a feedstock supply system with n different sources of biomass (j=1, 2, 3, …, n), where the variance of annual supply of individual feedstock j is j 2 , its biomass cost is Ej , and biomass from n sources is mixed in a proportion wj for biomass source j such that ∑wj = 1 for all j's to form a feedstock portfolio. The effective cost of the diversified feedstock portfolio is then (1) and the expected supply variance of the diversified feedstock portfolio is ,…”

Several studies have highlighted that one of the largest risks with cellulosic biorefinery investments are year-to-year variability in cellulosic biomass quantity available. Yet, strategies to mitigate these risks in biofuel development are less understood. In the absence of strategies to minimize the impact due to these variations, both biorefineries and farmers venturing into the cellulosic biofuel arena will be significantly exposed. Studies have been done on using engineering approaches, such as biomass pretreatment and storage to address biomass supply variations. Recent studies have provided market structure and contracting strategies to manage biomass supply risks. However, storage, pre-treatment and similar engineering approaches lead to higher costs and has other limitations such as additional infrastructural requirements. There is a gap in understanding the use of feedstock (biomass) diversification and portfolio strategies to mitigate such risks. In this study a portfolio approach is developed and applied to the case of the US Corn Belt, considering various types of cellulosic biomass including corn stover, wheat straw, and switchgrass. It is found that feedstock diversification mitigates up to 40% of feedstock supply variations, while biorefinery diversification can mitigate up to 70% of feedstock supply variations although it is constrained by current cropland use patterns in the region. Overall, diversification and portfolio strategies present an effective way for mitigating risks associated with feedstock supply variations.
