Prospects of Processing Buckwheat Нusk into Biochar
https://doi.org/10.18412/1816-0395-2025-12-40-45
Abstract
The possibility of recycling buckwheat husks by pyrolysis is considered. It was found that at a temperature of 550 °C and a heating rate of 5 °C/min, the yield of biochar, bio-oil and gas obtained by thermochemical conversion amounted to 33.92, 40.34 and 25.74 % of the used raw materials (by weight) accordingly It was revealed that the heat of combustion of biochar is equal to 7404–7593 kcal/kg, which is comparable to the calorific value of hard coal. The break-even point of an enterprise processing 30 tons of husk per day and producing 3,154.56 tons of biochar annually was determined. It is noted that this technology will also reduce greenhouse gas emissions by 7,486 tons per year, which will help reduce the carbon footprint.
