This is due to the increased environmental impacts of petroleum and the desire to reduce the use of petroleum. Potential substitutes include cellulose from fibrous plant materials as a substitute for oil-based products. Plastics can be created by cellulose instead of oil and plant fat can be substituted for oil to fuel cars. In order for ...
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]
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 ...
Tailpipe emissions of CO 2 also decrease due to the lower carbon-to-hydrogen ratio of these alcohols, and improved engine efficiency. Methanol and ethanol fuels contain soluble and insoluble contaminants. [5] Halide ions, which are soluble contaminants, such as chloride ions, have a large effect on the corrosivity of alcohol fuels. Halide ions ...
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 ...
Exposure to these substances can result in health effects such as skin irritation, respiratory problems, organ damage, neurological effects, and cancer. [4] Physical hazards are factors within the environment that can harm the body without necessarily touching it. They include a wide range of environmental factors such as noise, vibration ...
