Ethanol fuel is ethyl alcohol , the same type of alcohol found in alcoholic beverages , used as fuel. It is most often used as a motor fuel , mainly as a biofuel additive for gasoline. The first production car running entirely on ethanol was the Fiat , introduced in in Brazil by Fiat.

Potato peel waste-its nutraceutical, industrial and biotechnological applacations

E-mail s : ugaekon yahoo. Production of ethanol fuel from organic and food waste has been carried out with the singular aim of converting the waste to useful material. This was then converted into ethanol by fermentation process using Sacchromyces ceverisiae. Fermentation Kinetic parameters were evaluated. Considering the percentage fermentable sugar yield from the biomasses in study, it is more economical to produce ethanol from food waste maize than old organic waste old newspaper. Studies [] have revealed that there are attempts to develop alternative source of energy so as to conserve the dwindling reserves of crude oil and fossil fuels. The world population and increased urbanization have directly or indirectly influenced the energy demand.

A Review on Ethanol Production from Agricultural Waste Raw Material

Citation: Kuan-Chen Cheng et al. DOI: Inclusion of bioethanol in the transportation fuel by displacing part of the petroleum-derived energy has become an emerging trend due to limited availability of fossil fuel and its potential association with global warming. In this study, a conceptual design of ethanol production by Saccharomyces cerevisiae converting the byproducts from sweet potato processing was proposed based on experimental data and previous publications. The fermentation section of the plant consists of two feed tanks, in which sweet potato peel is pre-treated, diluted and standardized, one batch aerobic reactor for microbial culture enrichment, and two parallel systems each consisting of two continuous an aerobic and an anaerobic respectively reactors for further culture enrichment and ethanol production. As the world economic growth and technological advancement are both highly rely on the sufficient energy supply, which currently are mainly based on the non-renewable energy sources. When the most world utilized energy source [1] , fossil fuel, imposes serious environmental stress through generating excessive polluting gases, the renewable biomass energy is now widely regard as the most promising alternative for humankind to meet their increasing energy need with lower environmental cost [2].

Organic waste are a potential source of biofuels. On average, The control samples without addition of enzymes showed amounts of reducing sugars similar to samples subjected to enzymatic hydrolysis with The results showed that among the varieties tested, there were no significant differences in reducing sugars and ethanol parameters: however, the blanca variety exceeds the chola one with the highest concentration of ethanol and reducing sugars after the enzymatic hydrolysis, surpassing the chola veriety with Adina, C.

Industrial wastes are of great interest as a substrate in production of value-added products to reduce cost, while managing the waste economically and environmentally. Bio-ethanol production from industrial wastes has gained attention because of its abundance, availability, and rich carbon and nitrogen content. In this study, industrial potato waste was used as a carbon source and a medium was optimized for ethanol production by using statistical designs. The effect of various medium components on ethanol production was evaluated. Using response surface methodology, a medium consisting of In conclusion, this study demonstrated that industrial potato waste can be used effectively to enhance bioethanol production. Alternative fuels are of great interest due to the price fluctuations of petroleum-based fuels, government regulations on carbon dioxide emissions, and future depletion of petroleum reserves.

Metrics details. China is the largest sweet potato producer and exporter in the world. In China, more than 2 million tons of SPRs cannot be utilized, and the unutilized SPRs are perishable and result in environmental pollution. Thus, an environmentally friendly and highly efficient process for bioethanol production from SPRs should be developed.

Это единственное решение. Единственное, что остается. Нужно было думать о долге - о стране и о чести. Стратмор полагал, что у него еще есть время.

Она металась между дверцами кабинок и рукомойниками. Потеряв ориентацию, двигалась, вытянув перед собой руки и пытаясь восстановить в памяти очертания комнаты. Споткнулась о мусорный бачок и едва не наткнулась на кафельную стенку.
