While biodiesel has been around for almost one hundred years, until the past two decades, biodiesel has not demanded the attention it does now as a viable major alternative, both as a money-making opportunity and as an environmental silver bullet.
While biodiesel has been around for almost one hundred years, until the past two decades, biodiesel has not demanded the attention it does now as a viable major alternative, both as a money-making opportunity and as an environmental silver bullet.The trouble is that as in most environmental questions, there are two (or more) sides, and they are a little like nitro and glycerin. Thus, while some crops are capable of producing tomorrow’s industrial fuels, there is the potential cost, in starvation and the planet’s survival.This sample environmental science research paper explores the importance and significance of biodiesel production methods that will enhance ecological security.Tags: Social Norms EssaysThe Term Paper ArtistComputer Repair Business PlanFinished Research PaperMcat Essay Score RangeCreative Writing MagazineEssays On The InfluenceProfessional Paper WritingOhio U Creative WritingEssay On Should Animals Be Used In Research
But it seems that no matter in which direction a step is taken, there is peril and some objections from some interested group.
Since biodiesel can be made from, among other things, food crops, there are those who believe producing them does not meet ecological, environmental, and human needs.
It is more likely that land-use constraints will limit the amount of new land that can be brought into production leading to a “food-versus-fuel” debate.
Moreover, land use will be driven by the net private benefit owners can derive from their land.
While some developing countries with vast geography may see biodiesel as a future export industry and domestic solution to oil dependence, it often comes at the expense of using those same fields to grow food, or at the cost of clear-cutting trees which are essential to the earth’s supply of oxygen.
Sorting out the multitude of competing claims is never easy.
On the other hand, biodiesel does have some low temperature performance issues, having to do with the formation of wax crystals, resulting in clogging, and this is generally worse for yellow grease biodiesel than soybean biodiesel. Traditionally, in colder climates, this could pose performance challenges.
However, there are additives and strategies (such as heaters, parking vehicles inside in Winter, using engine block or fuel filter heaters) that can be utilized to reduce the effects of cold weather. There are also limitations on some of the sources of biodiesel feedstocks, as for instance with yellow grease, which in the United States is insufficient to meet transport fuel requirements. On the other hand, China produces enough yellow grease annually (44 billion gallons, over twenty times as much as the United States) to satisfy a larger portion of its lower biodiesel requirements. Another downside, as described in Liu, et al, and Table 3 therein, is that for plant oils, enormous tracts are land would be needed, monopolizing too much of a country’s arable land for non-food production, and resulting in cutting down far too many trees. currently limit the number of trees removed and require equal number replanted in another location.
(Radich 1) Diesel’s engine differed from the engine created by Nicklaus Otto in that Diesel’s system did not require a spark.
Ignition was based on compression of the fuel until it ignited. Diesel foresaw being able to use vegetable oil to run his engines, making it easier to produce fuel wherever his engines were available.
