IIT-KGP develops Hydro Thermal Carbonization technology for Waste Management

IIT-KGP (Indian Institute of Technology Kharagpur) researchers develop new technology- Hydro Thermal Carbonization (HTC) for solid waste management. This Hydro Thermal Carbonization Technology can convert municipal solid waste to biofuel, soil amendment and absorbents.

About Hydro Thermal Carbonization (HTC)

Need: At present India has adopted waste incineration processes from developed nations which are primarily focused on treating drier waste content. These processes require high energy input to combust municipal solid waste generated in India which has high moisture content due to tropical weather, open collection systems and mixed waste thus by using existing processes, only 20-30% of organic fraction of municipal solid waste is being recycled to biofuel. This lack of India suited technology led to develop a technology which can address the challenge indigenously.

Process: Moisture in waste is used to the advantage of process which uses water for reaction. The biofuel generated as recovered output can help curb air pollution.

Benefits:

Technology can be used by civic bodies to effectively manage solid waste.

Once organic waste is entered into process, the outputs generated are all usable.

All outputs can be used for one purpose or the other, including the water which can be converted to biogas or methane.
