GS Paper - 3 (Agriculture)

The Indian Institute of Technology (IIT) in Hyderabad inaugurated India’s first building made of bio-bricks from agro-waste. Calling it a perfect illustration of ‘Wealth from Waste’, IIT-H Director BS Murthy said the institute will submit a proposal to the Ministry of Agriculture to promote its wider adoption by the rural community.


  1. Researchers at the IIT demonstrated that agricultural waste can be converted into sustainable materials which, in turn, can be used to build eco-friendly, cost-effective structures. In April this year, the team secured a patent for the bio-brick material and its manufacturing technology.
  2. It is part of the Bold Unique Idea Lead Development (BUILD) project to demonstrate the strength and versatility of the material.
  3. This innovation is going to be a game-changer for rural village farmers as their agricultural waste will become an income generator for them.
  4. Burning of agro-waste after harvest is a major cause of air pollution. The bio-brick technology was developed to counter such pollution caused by stubble burning.
  5. Bio-bricks are economical and are found to be 1/8 and 1/10 of weight for similar volume compared to burnt clay bricks and concrete blocks, respectively.
  6. According to the researchers, the material exhibits excellent thermal insulation and fire-retardant properties. When used in roofing and wall panelling, it can effectively reduce heat gain by 5 – 6 degrees.
