“…The MISCANMOD estimates yields of miscanthus and Cave-in-Rock variety of switchgrass using GIS data, at a 1 o by 1 o scale, on climate, soil moisture, solar radiation and growing degree days as model inputs, as described in Jain et al (2010). The Cave-in-Rock switchgrass cultivar studied here is an upland variety that originated in Southern Illinois and is cold-tolerant and well-suited for the upper Midwest (Lemus and Parrish 2009;. Lowland varieties of switchgrass, like Alamo, are most suited for southern US (Lemus and Parrish 2009).…”

Biofuel production is being promoted through various policies such as mandates and tax credits. This paper uses a dynamic, spatial, multi-market equilibrium model, Biofuel and Environmental Policy Analysis Model (BEPAM), to estimate the effects of these policies on cropland allocation, food and fuel prices, and the mix of biofuels from corn and cellulosic feedstocks over the 2007-2022 period. We find that the biofuel mandate will increase corn price by 24%, reduce the price of gasoline by 8% in 2022, and increase social welfare by $122 B (0.7%) relative to Business As Usual scenario. The provision of volumetric tax credits that accompany the mandate significantly changes the mix of biofuels produced in favor of cellulosic biofuels and reduces the share of corn ethanol in the cumulative volume of biofuels produced from 50% to 10%. The tax credits reduce the adverse impact of the mandate alone on crop prices and decrease the price of biofuels. However, they impose a welfare cost of $79 B compared to the mandate alone. These results are found to be sensitive to the rate of growth of crop productivity, the costs of production of bioenergy crops, and the availability of marginal land for producing bioenergy crops.

“…The discrepancy was mainly due to biomass not recovered by current harvesting equipment, while slope and site‐specific soil conditions had secondary effects . Likewise, results seen with two or three years of some management strategies may not continue over longer terms …”

“…In both the USA and the EU, most energy cropping studies have been carried out in small‐scale field trials, testing adaptation, productivity, and management practices across diverse sites. Various European and US projects have determined that switchgrass, reed canary grass, miscanthus, and giant reed are among the more promising perennial grasses for second‐generation feedstocks . Forage or biomass sorghum, an annual grass, has also been identified as a very promising feedstock in the USA and the EU .…”

A concise and up‐to‐date review has been undertaken to summarize consistent or diverging agronomic points of view on dedicated energy crops for advanced biofuels in the USA and the EU‐27. The main purpose of this review is to discuss those crops where many agronomic constraints have been resolved, bringing them closer to large‐scale production and commercialization. Where possible, examples of crop management practices that would enhance sustainability and energy yields are provided. The most promising crops and agronomic strategies for their production in the EU‐27 and the USA are discussed. We also provide discussion of what the theoretically ideal characteristics of advanced biofuel crops might be. On both continents, understanding of management practices for switchgrass (Panicum virgatum L.) and miscanthus (Miscanthus x giganteus) as energy crops appears to be at an advanced stage. Two other widely considered energy crop candidates – sorghum (Sorghum bicolor (L.) Moench) and reed canary grass (Phalaris arundinacea L.) – have production and management guidelines that were developed for forage uses, but can be easily applied to biomass feedstock production. Giant reed (Arundo donax L.) has been developed as a bioenergy crop mainly in Europe. In the USA, giant reed is considered a noxious weed in many states, and its planting is prohibited. Establishing crop management practices that will be successful at a large scale and for the long term will help attract growers and investors to produce advanced biofuels, i.e. second‐generation biofuels, which can help reduce our dependence on fossil energy sources. © 2013 Society of Chemical Industry and John Wiley & Sons, Ltd

“…The enzymatic hydrolysis of lignocellulosic materials to produce biofuels or other products through their depolymerization into fermentable sugars has been investigated extensively . For this purpose, herbaceous crops were initially identified as among the best raw materials because of their renewable nature, high growth yield and suitable chemical composition . However, there are many other different alternatives to herbaceous crops for this.…”

A kinetic model considering the heterogeneous nature of the enzyme hydrolysis of lignocellulosic materials

In this work, a mathematical model is proposed to predict the kinetic behaviour of the enzymatic conversion of various types of lignocellulosic biomass into fermentable sugars. Digestion of the cellulosic polymers is carried out using enzymatic hydrolysis under different conditions. Unlike other kinetic models, published previously for this process, this one considers the heterogeneous nature of the process by which a solid, in the form of small particles, is decomposed to monosaccharides by the action of a diverse set of enzymes in solution. The effect of the particle size on the hydrolysis rate has also been taken into consideration. To assess the model's goodness of fit to any general situation, the experimental data obtained in the hydrolysis of three different lignocellulosic residues have been analysed. Thus, the hydrolysis data of wheat straw, rice husks and exhausted sugar beet pellets have been compared with the theoretical values calculated by the model. The results obtained show that this model predicts the enzyme's hydrolysis of lignocellulosic substrates under different conditions very accurately and it could therefore be used efficiently in the optimization of the hydrolysis processes implemented in the bio-refinery industry. is a lecturer in the Department of Chemical Engineering and Food Technology at the University of Cádiz, with a background in chemistry and a PhD in chemical engineering from the same university.
