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.
Phytotoxicity describes any adverse effects on plant growth, physiology, or metabolism caused by a chemical substance, such as high levels of fertilizers, herbicides, heavy metals, or nanoparticles. [1] General phytotoxic effects include altered plant metabolism, growth inhibition, or plant death. [2]
Current corn-ethanol technologies are much less petroleum intensive than gasoline however have the GHG emission levels similar to gasoline. [77] The literature is mainly unclear what the GHG emission changes would be by adopting corn-based ethanol for biodiesel. Some studies report a 20% increase in GHG emissions and some report a 32% decrease.
Since the 1970s, the U.S. has subsidized ethanol produced from food crops, especially from corn, thus providing a homegrown, alternative fuel source for our automobiles. But for multiple reasons ...
Food vs fuel is the debate regarding the risk of diverting farmland or crops for biofuels production in detriment of the food supply on a global scale. Essentially the debate refers to the possibility that by farmers increasing their production of these crops, often through government subsidy incentives, their time and land is shifted away from other types of non-biofuel crops driving up the ...
Cellulosic ethanol is ethanol (ethyl alcohol) produced from cellulose (the stringy fiber of a plant) rather than from the plant's seeds or fruit. It can be produced from grasses , wood , algae , or other plants.
The problem, DeCarlo said, is that storage in the cannisters appears to alter the concentration of the gas. DeCarlo said that current regulatory figures on ethylene oxide levels are based on ...
A dish of ethanol aflame. Various alcohols are used as fuel for internal combustion engines.The first four aliphatic alcohols (methanol, ethanol, propanol, and butanol) are of interest as fuels because they can be synthesized chemically or biologically, and they have characteristics which allow them to be used in internal combustion engines.
