Ethanol and biodiesel production have become important industries worldwide. For example, ethanol production in the United States has increased exponentially from 6.0 billion liters in 2000 to 49 billion liters in 2010, an increase of 800% (RFA, 2011). Similarly, biodiesel production increased in the U.S. from 424 million liters in 2005 to 1,191 million liters in 2010 (NBB, 2011). These booming...

s: Background: Several studies have reported the hypoglycemic property of Fenugreek seeds (Trigonella foenum graecum), a commonly used condiment in Indian homes, due to its high dietary fiber content. Method: A total of 25 NIDDM patients were given control diets orally consisting of (i)milled rice(boiled rice),(ii) whole wheat (chapati) experimental diets consisting of (iii) boiled rice with fe...

Biodiesel is a low-emissions diesel substitute fuel which is made from renewable sources that consists of the simple alkyl esters of fatty acids. Research and development in the field of biodiesel showed that one way of reducing the biodiesel production costs to compete economically with petroleum diesel fuels is by use the less expensive feedstock containing fatty acids such as inedible oils. ...

Present process of transesterification faces various challenges. The most challenging is to obtain high conversion rate when using high free fatty acid (FFA) feedstock. The aim of this study is to investigate transesterification process of rubber seed oil (RSO) through direct-ultrasonic irradiation (UI) with addition of waste material based heterogeneous catalyst. The waste material based heter...

Increasing global concern over the environmental issues and depletion of fossil fuels, significant interest has been shown by the researchers to develop alternate energy technologies like biomass, biogas, solar to meet the future energy demand. The prediction of the performance of different biomass energy sources in gasifiers is needed for the implementation of this technology to fulfil the nee...

Revalorization of the winery industry residue, grape seed is studied for the production of an oil and defatted meal with nutraceutical properties. Conventional grape seed oil extraction process is carried out by pressing at high temperature affecting the product quality. Oil extraction by cold pressing improves product quality, but it gives a low oil yield. Oil extracted is increased at the pre...
