Search efforts continue to be renewable energy, particularly renewable energy is environmentally friendly. Some countries and industrial policies in the energy sector in the past five years is to strengthen the development of biofuels. So far, development efforts have been made in various ways, including the use of biomass for alternative energy in biofuels.
Biofuel donate products in an environmentally safe energy, also contribute to the procurement of renewable energy. Today, the world is racing to provide renewable energy. Among the developed technology to produce biofuel and bioethanol.
Bioethanol is generally made from starchy crops such as cassava, sweet potato, sago and sorghum. Can also be made from sugary crops such as sugarcane, sweet sorghum, and others. A variety of fibers such as straw and bagasse can also be processed into alternative fuel called bioethanol.
In fact, with a simple technology of waste separation and household waste, it can also be obtained material for bioethanol processing. Former waste any fire, bioethanol can be used as material.
Cellulose Technology
Cellulose, derived from sebulir foliage with the help of the sun and rain to produce sugar for conversion into cellulose.
During this time, the process of formation of sugars is by polymerization. However, in bioethanol technology under development process can be reversed. sample material from selulosanya sugar. Source of the fibrous ligno cellulosic biomass that is separated from lignin (a binder fiber) and will get the fiber.
Fiber is then undergo hydrolysis to obtain silanase enzyme that produces sugar. Then, the sugar is fermented to produce ethanol. In the extractive process, will be a lot of polyphenols. For example contain tannins, such as from sewage treatment plants are a lot of paper. Only, for biomass from cellulose is a problem, namely the separation lignin.
