 1. Scientists at IIT Kharagpur Develop New Technology to Manufacture Biofuel.

The new technology makes use of natural resources to extract gaseous and liquid biofuel and then converts the wastes into bio fertilizer. At present 2gm of bioethanol can be manufactured from various naturally available ligno-cellulosic components.

However, this process requires chemical treatment that results in polluting the environment. Lignocellulose refers to biomass. The new technology has replaced this chemical treatment with enzymes which degrade the lignin thereby making the manufacturing process totally pollution free. 

Lignins are complex organic polymer deposited in the cell walls of  plants. In this process, the residual biomass can be used as organic fertilizer. 

The Project is funded  by the Ministry of Petroleum and Natural Gas, Department of Science and Technology and the Ministry of Human Resource Development.  

The scientists used corn, sugarcane plants, the waste part of paddy straw, bamboo, banana plant, pineapple and cotton plants, kans grass (kassh phool), castor plant etc to produce biofuel.
