When having to wonder how the environment is fairing with all the global warming and climate changes on going in the world. There are more of the renewable fuels to use like biofuels and biomass we have to wonder how all of this will affect the ever changing of the environment. There are several different environmental problems of biofuels and biomass in the world. We often wonder about the comparison of energy security by biofuels and biomass combined together, because these items are being used for energy and the future of our environmental issues and science.
Most of the biofuels and biomass are combined to be used in agricultural situations that are continuing to affect our environment through energy security. It seems that biomass come from bioenergy and are efficient to our environment to contain wood. “Bioenergy, the energy from biomass, has been used for thousands of years, ever since people started burning wood to cook food or to keep warm, and today, wood is still our largest biomass resource from bioenergy. Many countries in the developing world still use wood as their primary fuel (Demirbas and Demirbas, 2007). Wood is one of the carbonaceous fuels. The carbonaceous fuels are responsible for over 80% of the worlds energy production (Demirbas and Demirbas, 2007).” This is crazy with so much of comparisons of how biofuels and biomass are so close together in this environment.
Biofuels are derived from bioethanol which is used as gas for different vehicles like from corn and other agricultural items. With all the agricultural problems of food these environmental problems help for our country there is carbon dioxide and carbon monoxide that is trying to make the environment a better place to live. “Agricultural residues such as straws, nut shells, fruit shells, fruit seeds, plant stalks and stoves, green leaves, and molasses are potential renewable energy resources. Current disposal methods for these agricultural residues have caused widespread environmental concerns (Demirbas and Demirbas, 2007).” We do not realize the advantages of having the biofuels and biomass dealing with agricultural items and other renewable energy resources that affect our environmental world. With all the talk about renewable energy resources that are being tried to incorporate renewable fuels into our future plans for the world and country (Easton, 13th ed., 2010, pg. 207).
With all the talk about making the environment go green campaign we forget about how power plants are trying to use other resources like biofuels and biomass. We also don’t realize that electricity and other essentials are used from biomass. “The electricity is produced by direct combustion of biomass, advanced liquefaction, gasification, and pyrolysis technologies, which are almost ready for commercial-scale use (Demirbas, 1998). Residues remaining after the harvest of crop and forestry products are being proposed as a substantial energy source for generation of electrical power.” No one ever realizes that a lot of biomass and biofuels depend on the agricultural development of crops and other organisms.
Biomass or waste is a part of the pyrolysis that can be converted by using different waste to make the environment a better place. “Pyrolysis of biomass generates three different energy products in different quantities: coke, gas and oils. Flash pyrolysis gives high oil yields, but the technical efforts needed to process pyrolytic oils mean that this energy generating system does not seem very promising at the present stage of development. However, pyrolysis as a first stage in a two-stage gasification plant for straw and other agricultural materials does deserve consideration. efforts needed to process pyrolytic oils mean that this energy generating system does not seem very...
