This paper reviews an analysis of land use change impacts of expanded biofuel production with GTAP-BIO computable general equilibrium (CGE) model. It describes the treatment of energy substitution, the role of biofuel by-products, specification of bilateral trade, the determination of land cover changes in response to increased biofuel feedstock production, and changes in crop yields – both at ...

Sweet sorghum is a promising target for biofuel production. It is a C4 crop with low input requirements and accumulates high levels of sugars in its stalks. However, large-scale planting on marginal lands would require improved varieties with optimized biofuel-related traits and tolerance to biotic and abiotic stresses. Considering this, many studies have been carried out to generate genetic an...

Lignocellulosic hydrolysate (LCH) inhibitors are a large class of bioactive molecules that arise from pretreatment, hydrolysis, and fermentation of plant biomass. These diverse compounds reduce lignocellulosic biofuel yields by inhibiting cellular processes and diverting energy into cellular responses. LCH inhibitors present one of the most significant challenges to efficient biofuel production...

Biofuel and biochemical production by photosynthetic microorganisms such as cyanobacteria and algae is attractive to improve energy security and to reduce CO2 emission, contributing to the environmental problems such as global warming. Although biofuel production by photosynthetic microorganisms is called as the third generation biofuels, and significant innovation is necessary for the feasibil...

When tens of thousands of people staged demonstrations in Mexico last year to protest a 60 percent increase in the price of tortillas, many analysts pointed to biofuel as the culprit. Because of US government subsidies, American farmers were devoting more and more acreage to corn for ethanol than for food, which sparked a steep rise in corn prices. The diversion of corn from tortillas to biofue...

Oils of a significant value both as fuels as well as for cosmetic applications can be extracted from the fruits of the jojoba plant. After extracting the oil, the remains of the fruit can still be further utilized as a solid fuel in furnaces or feedstock to animals. In the present work, the solid waste jojoba remains have been processed chemically to extract more biodiesel oil. The physical and...

We develop a two-region partial equilibrium model of the global market for liquid fuel and analyze different policies, such as biofuel mandate, emission standard, and fuel carbon tax. We rank these policies under different criteria, such as greenhouse-gas (GHG) emissions, expenditure on fuel imports, the impact on fuel consumers and producers, the quantity of biofuel, etc. Our analysis suggests...

Problem statement: In today’s scenario, microalgae are widely recognized as a promising source for biofuel production as a renewable source of energy. They are exceedingly rich in oil, which can be converted to biofuel. This paper deals with one of the method to enhance the lipid content in microalgae. Approach: Microalga, Chlorella pyrenoidosa, was grown autotrophically in batch culture and th...

Microalgae have gained enormous consideration from scientific community worldwide emerging as a viable feedstock for a renewable energy source virtually being carbon neutral, high lipid content, and comparatively more advantageous to other sources of biofuels. Although microalgae are seen as a valuable source in majority part of the world for production of biofuels and bioproducts, still they a...

Fossil fuel depletion and attempts of global warming mitigation have motivated the development of biofuels. Several feedstock and transformation pathways into biofuel have been proposed as an alternative to usual fuels. Recently, microalgae have attracted a lot of attention because of the promise of reduced competition with food crop and lowered environmental impacts. Over the last years, sever...
