Bioethanol

Bioethanol is currently the most commonly produced and used biofuel in the world, with global production of fuel ethanol accounting for 54% of all cumulative biofuel investment in 2010, with a major concentration in the United States and Brazil (sugarcane ethanol). Ethanol blends improve engine combustion and reduce emissions of carcinogens such as carbon monoxide, sulfur dioxide, unburned hydrocarbons, and soot. As a result, a growing number of countries have explicitly required a certain amount (10-15%) of ethanol to be added to gasoline as a transportation fuel to ease the pressure on oil consumption while reducing the release of air pollutants.

Our Solution

The process of producing ethanol from sugar and starch raw materials is well established, but because its raw materials are mainly food, it is easy to cause a situation of competition with food for land, and it is difficult to meet the demand for energy in the long term, so the production is greatly restricted. Cellulose, which is rich in resources and a renewable energy source, is the most important biomass resource and has become the main raw material for fuel ethanol production.

• Sugar, from sugar cane, sugar beet, etc.
• Starch, from corn, grain, etc.
• Wood fiber, from straw, bagasse, etc.

Feedstock	Background	Process
Corn	Corn germ is an important source of fat and protein High waste lees treatment load and energy consumption with the residue fermentation process Thick mash fermentation of lees mash is rich in nutrients Reduce the average time of continuous fermentation, increase the production intensity of the equipment and reduce pollution	Supercritical extraction process Research on thick mash fermentation, a high proportion of waste lees direct recycling technology or use of solid fermentation For the production of chemical and pharmaceutical products, enzyme preparations, etc. Clear liquor fermentation with self-flocculation of yeast cells
Molasses	Improvement of wine production rate Improving the quality of molasses pretreatment Reduction of emission pollution Shorten fermentation cycle and increase fermentation rate	Continuous fermentation technology for flocculated yeast Immobilized yeast production technology
Straw	Degradation of straw Cellulase is expensive Improvement of cellulase properties Only some microorganisms in nature can use pentose for fermentation or ethanol production Disinhibition of enzyme products	Pretreatment with dilute acid + cellulase hydrolysis Use of liquid fermentation method Enzyme design and directed evolution techniques Construction of genetically engineered bacteria with multiple advantages Simultaneous saccharification and fermentation process

Bioethanol production from cellulosic feedstock

• Reduce the cost of cellulase production.
• Research new and efficient methods of cellulase recovery and reuse.
• Increase the yield of cellulose glycolysis and the conversion of sugar fermentation to ethanol.
• Select and cultivate microorganisms through genetic engineering to increase enzyme yield and improve enzyme activity.
• Develop new microorganisms to solve the problem of difficult fermentation of pentose.
• Develop advanced ethanol fermentation and distillation processes and equipment.

Our Focus

As early as July/August 2000, the Futurist magazine published a projection by experts from George Washington University that within the next 10 years, the market for the mass production of ethanol from plant-based raw materials for fuels, etc. will form a large industry, currently at a stage similar to that when the petrochemical industry was poised to boom and oil replaced coal as the main energy source. That is why Lifeasible is also actively seeking to maximize the use of bioenergy, especially in bioethanol.
