According to some estimates, expansion by Indonesian palm oil plantations caused the vast majority of that nation's deforestation in the late '80s and '90s. : Premium Gasoline Delivers Premium Benefits to Your Car. Potential drawbacks include changes to land use patterns that may increase GHG emissions, pressure on water resources, air and water pollution, and increased food costs. #1 Land use changes and land grabbing However, this is not the only reason to encourage the use of biofuels. In addition, biofuels are biodegradable, which reduces the risk of contamination of and underground water during transportation, storage, or use. According to studies, the levels of carbon dioxide emissions and particulate matter are reduced with biofuels, however, the nitrogen oxides are slightly higher than at fossil fuels [1]. Therefore, the use of biofuels is less of a drain on the wallet. Long-time monoculture farms have to use much more artificial fertilizer than their more sustainable peers, increasing water pollution.

In fact, the 468 million metric tons of trash produced in North America each year could provide 47 billion liters of ethanolor roughly the same amount as produced from corn, which presently supplies 10 percent of U.S. gasoline demand. Given the expense of converting this mix of dirt and heavy oils to more usable petroleum products, the province is not keen on alternative fuels. Similarly, BlueFire Ethanol turns waste into ethanol by using sulfuric acid to release the cellulose in the trash and then adds enzymes and microbes to ferment it into fuel. Waste tires based biorefinery for biofuels and value-added materials They are found in liquid, solid or gas states. Most of the waste generated worldwide is biodegradable. References: Ann, Ngee. The regional nature of high-producing plants such as palm oil means that certain parts of the world are agricultural gold mines: Biofuel demand motivates plantations to expand quickly.
