Crops like Jatropha, used for biodiesel, can thrive on marginal agricultural land where many trees and crops won't grow, or would produce only slow growth yields. [51] [52] Jatropha cultivation provides benefits for local communities: Cultivation and fruit picking by hand is labour-intensive and needs around one person per hectare.
An Austrian company, Gaskoks, obtained the technology from the South African Agricultural Engineers; the company erected the first biodiesel pilot plant in November 1987, and the first industrial-scale plant in April 1989 (with a capacity of 30,000 tons of rapeseed per annum).
Brazilian cerrado Amazon rainforest. The indirect land use change impacts of biofuels, also known as ILUC or iLUC (pronounced as i-luck), relates to the unintended consequence of releasing more carbon emissions due to land-use changes around the world induced by the expansion of croplands for ethanol or biodiesel production in response to the increased global demand for biofuels.
The RFS acts as a boost to the US agricultural sector by providing an additional source of demand for U.S. agricultural products, and increases rural incomes and rural employment opportunities. Supporters argue that renewable biofuels go unrecognized for the full extent of their environmental benefits.
Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and esterification. [1] This process renders a product (chemistry) and by-products. The fats and oils react with short-chain alcohols (typically methanol or ethanol). The alcohols used should be of low molecular weight.
Biodiesel is produced from the oils in for instance rapeseed or sugar beets and is the most common biofuel in Europe. [citation needed] Second-generation biofuels (also called "advanced biofuels") utilize non-food-based biomass sources such as perennial energy crops and agricultural residues/waste.
There is also an added incentive to develop the bioenergy sector which is to increase the development of the rural agricultural sector. As of 2005, bioenergy use has reached more than 20 million households in the rural areas, with methane gas as the main biofuel.
The following table shows the vegetable oil yields of common energy crops associated with biodiesel production. Included is growing zone data, relevant to farmers and agricultural scientists. This is unrelated to ethanol production, which relies on starch, sugar and cellulose content instead of oil yields.
