Converting Plastic and Biomass to Manure
Researchers at the University of Agricultural Sciences, GKVK, Bengaluru, India installed a pyrolysis unit to convert plastic and biomass into valuable manure and pesticide. The results were surprising as the pyrolysis process yields a range of useful products. When applied to plastic waste, it produces char, a key material in asphalt and brick manufacturing.
It generates syngas, a clean-burning gas that fuels the pyrolysis unit itself, and bio-oils that can be used for various energy applications. Processing biomass through pyrolysis also produces biochar, often referred to as “black gold” by the by the agro fraternity. The experiment started in 2016 with 25 kg of plastic and biomass. It was later scaled up to a 200 kg capacity combustion chamber, fuelled by plastic, biomass, and locally made bio-briquettes.
