About the Practice
Problem Statement:

There is no question that the construction sector massively contributes to global warming. In India itself, the industry emits 22% of the total annual CO2 emissions. And then there is agricultural waste—the country produces more than 500 million tons of it every year. While some of the waste is used as fodder, approximately 141 million tons are burnt every year. Clay bricks not only use up fertile topsoil, but their manufacturing process also emits significant amounts of carbon dioxide into the atmosphere. Bio-bricks are not only more sustainable than clay bricks, but are also carbon sinks because they fix more carbon dioxide than they produce during their lifecycle.


Architects Priyabrata Rautray, who is also a PhD scholar in IIT Hyderabad’s Design Department, and Avik Roy, an Assistant Professor at the KIIT School of Architecture, Bhubaneshwar, have developed bio-bricks for construction from agricultural waste products. This innovation addresses both waste management and development of eco-friendly, sustainable building materials. Guidance for the project came from Prof Deepak John Mathew, Head, Design Department, IIT Hyderabad and Dr Boris Eisenbart from Swinburne University of Technology, Australia. The process of making bio-bricks starts with careful selection of the dry agro-waste like paddy straws, wheat straws, sugarcane bagasse and cotton plant. The team decided to use dry sugarcane bagasse for the first sample. The bagasse is first chopped to the desired size. A lime-based slurry is prepared, and the chopped agro-waste is added to the slurry and mixed thoroughly by hand or mechanical mixer, to create a homogenous mixture. This mixture is poured into molds and rammed with a wooden block to make a compact brick. These molds are left to dry for a day or two, after which their sides are removed, and the brick is allowed to dry for fifteen to twenty days. It takes approximately a month for these bio-bricks to attain its working strength by air drying.

Practice Details

Link: It can properly turn and mix the compost ensuring that no lumps remain in it It helps in reducing the disease of Yellow mold in Mushroom It can add moisture and fungicide as well to control diseases It can be operated on all the surfaces easily - hard (pakka like cemented floor) and soft (kachcha like farmer’s field) Efficiency: Machine can heap mushroom compost of 200 ft. in length, 4 feet width and 4 feet height in 25 minutes. Using this machine, the time required for compost preparation is reduced considerably Production of mushroom is about 5-10 % more than that through the conventional manual process
