A research team at IIT Kharagpur has developed a technology called Hydro Thermal Carbonization (HTC)that can generate energy from solid waste with high moisture content.

About Hydro Thermal Carbonization (HTC) Technology

  • The new technology can convert municipal solid waste to biofuel, soil amendment and absorbents.
  • This technology is already in use in Japan and Germany. 
  • And the development has led to India having its own technology.
  • The technology is aimed at conversion of wet biomass into hydro-char (a coal like fuel) under suitable temperature and pressure conditions.
  • The moisture in the waste is used to the advantage of the process which uses water for the reaction. 
  • Use of byproducts
    • Once the organic waste is entered into the process, the "outputs generated are all usable.
    • Including the water which can be converted to biogas or methane.
    • Byproducts include ash which can be applied as a plant nutrient enhancer because of its phosphorus content
    • Potassium loaded liquid can be used for watering plants.
  • The biofuel generated as the recovered output can help curb air pollution.
  • The technology can be used by the civic bodies to effectively manage solid waste.
