‘Eureka’ IIT researcher develops a new technology to yield Biofuel from weed.

Biofuel: – Fuel that is produced through contemporary biological processes, such as agriculture and anaerobic digestion.

General process of manufacturing biofuel.

  • 2gm bioethanol can be produced from various naturally available ligno-cellulosic components (dry plant matter).
  • To do so it needs to be treated chemically. Because of chemical treatment the process contributes to polluting the environment
  • Lignin is a complex organic polymer deposited in the cell walls of many plants, making them woody .
  • These waste products do no degrade easily in environment.

Changes in the process.

  • It is soil-to-soil technology, an integrated process where natural resources are used to extract gaseous and liquid biofuel and then
    converting the wastes into bio fertilizer
  • The chemical treatment is replaced with enzymes which degrade the lignin specifically there by making the manufacturing process pollution free
    .
  • Since the waste material are degraded easily can be used as fertilizers in farms.

Benefits.

  • Cost effective.
  • Pollution free.
  • Consumes less time in production.
  • The green leafy part of corn and sugarcane plants, the waste part of paddy straw, bamboo, banana plant, pineapple and cotton plants, kans grass (kassh phool), castor plant and even non-edible weeds that grow in dry and waste land and a mix of all has been used by IIT-Kgp to produce biofuel.
  • An alternate to the other fuels which cause pollution, fossil depletion, greenhouse gas emission.

Targets.

  • The National Policy on Biofuel had set the target at 20% blending of bio-fuel with petrol by 2017.
  •  The government is expecting bio-fuel business in India to touch Rs 50,000 crore by 2022.
