Specialists from Tomsk Polytechnic University have developed a cost-effective method for disposing of coal mining waste. The new technology is based on the use of microwave pyrolysis with organic waste as a catalyst.
Unlike traditional, costly methods of accelerating pyrolysis, Tomsk scientists have proposed a more economical solution. They found that adding biomass, such as cedar nut shells or cow manure, to coal dust significantly improves the process. Leading researcher Roman Tabakaev explained that the developed raw material compositions are based on studying the dependence of product yield on time. One of the components of the mixture acts as a catalyst, increasing the yield of liquid products. It has been experimentally proven that 10% manure doubles the rate of pyrolysis, and cedar shell reduces energy consumption by 47.5%, making waste processing more profitable and solving the problem of biomass disposal.
