This analysis of the Government of India’s National Policy on Biofuels argues that while the policy of ethanol blending in petrol is in the right direction, it is fraught with several problems which are rendering the approach ineffective. The most critical ones are the lack of sugar cane for producing ethanol and the policy on pricing of it.

This study presents bioconversion of water hyacinth (Eichhornia crassipes) to bioethanol using two-sequential steps of acid hydrolysis (10% sulfuric acid) and yeast (Candida intermedia) fermentation. A maximum ethanol yield (coefficient, 0.21 g g-1; productivity, 0.010 g l-1h-1) was comparable to predicted value (0.23 g g-1) obtained by CCD (Central Composite Design). Two colorimetric methods (phloroglucinol and dichromate assays) were used for determination of xylose and ethanol using UV-Vis spectrophotometer.

The greenhouse gas emissions of biofuels have been under discussion for years. Now studies commissioned by the European Union are putting pressure on biodiesel in particular.
