Transcript of GREEN CHEMISTRY
Bio fuels are a wide range of fuels which are in some way derived from biomass. The term covers solid biomass, liquid fuels and various bio gases. Bio fuels are better for the environment as they are renewable and release less CO2 in the Earth's atmosphere. BIO FUELS What is Green Chemistry? Green Chemistry is chemical research and engineering that encourages the design of the products and processes that minimize the use and creation of hazardous substances that affect animals and environment! Start using Bio Fuels Mr. Arnold!!!!!!! However, Bio fuels can also cause problems for the rainforests due to high demand. This video will give a better explanation. The European Environment Agency does not believe that Bio fuels help the environment! But are they really Helpful? Facts on Bio Fuels! According to the International Energy Agency, Bio fuels have the potential to meet more than a quarter of world demand for transportation fuels by 2050.
The world's largest bio diesel producer is the European Union, accounting for 53% of all bio diesel production in 2010.
Bio diesel is made from vegetable oils and animal fats.
By 2020, 10 per cent of the energy used in UK road and rail transport must come from renewable sources – this is the equivalent of replacing 4.3 million tonnes of fossil oil each year. The 12 Principles! It is better to prevent waste than to treat or clean up waste after it is formed.
Synthetic methods should be designed to maximize the incorporation of all materials used in the process into the final product.
Wherever practicable, synthetic methodologies should be designed to use and generate substances that possess little or no toxicity to human health and the environment.
Chemical products should be designed to preserve efficacy of function while reducing toxicity.
The use of auxiliary substances (e.g. solvents, separation agents, etc.) should be made unnecessary wherever possible and innocuous when used.
Energy requirements should be recognized for their environmental and economic impacts and should be minimized. Synthetic methods should be conducted at ambient temperature and pressure.
A raw material or feedstock should be renewable rather than depleting wherever technically and economically practicable.
Catalytic reagents (as selective as possible) are superior to stoichiometric reagents.
Chemical products should be designed so that at the end of their function they do not persist in the environment and break down into innocuous degradation products.
Analytical methodologies need to be further developed to allow for real-time, in-process monitoring and control prior to the formation of hazardous substances.
Substances and the form of a substance used in a chemical process should be chosen to minimize potential for chemical accidents, including releases, explosions, and fires.
Bio fuels support these laws however the European Environment Agency believes that Bio fuels require us to cut down forests that a necessity to our existence. Bibliography! http://en.wikipedia.org/wiki/Biofuel
