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.
