A biofuel is made from a biological process known as carbon fixation. These biofuels are gotten from the conversion of biomass, solid biomass, liquid fuels as well as biogases. The biofuels are continued to be known because of the high prices of fossil fuels and also for the purposes of ensuring fuel security in various countries. (Caye, D. & Terry W.2008). The biofuels are produced from two distinct ways; that is through metabolic by-products or from living organisms. Examples of biofuels include; bioethanol which is an alcohol made from fermentation process. Another example of biofuels is biodiesel which is made from vegetable oils as well as animal fats. Biofuels have got several ways in which they are made. Therefore in this essay I am going to analyze few methods.
Biofuels are made from materials known as feedstock. This comprises mostly of crops or products mainly waste vegetable oil. (Mitchell, D. 2010). These materials are converted to biofuels or bioenergy. These feedstocks have got merits and demerits depending on what percentage of biofuel can be gotten from them.
Feedstocks can further be classified as first and second generation. The former refers to those which are widely grown by people and at the same time used for some other purposes. They are mostly used for food and feed production. (Lane, J. 2010). Hence, they serve the purpose of being used as food as well as to produce biofuels. The examples of first generation feedstock include maize and vegetables.
Second generation feedstocks are those which produces high percentage of biofuel but they are not widely grown. They are at times referred to conventional crops and they produce a lot of biofuels. Examples of second generation feedstock are mustard and cellulosic feedstocks. ( Lane, J. 2010).
Gasification
This is a process which relies entirely on organic or fossil based carbonaceous materials and converts them into carbon dioxide,
