Many agro-industrial companies grow amaranth for subsequent production of amaranth oil, flour, cereals, flakes and bran. After the grain is extracted, waste in the form of inflorescences remains, which can be used to obtain new useful products. This work investigated the use of pyrolysis to recycle amaranth inflorescence wastes (AIW). Thermochemical conversion experiments in an inert medium were carried out on a laboratory setup at 550 °C and a heating rate of 10 °C/min. It was found that the AIW pyrolysis produced 37.1 % bio-oil, 35.8 % pyrogas and 27.1 % biochar. The tar fraction of the obtained bio-oil contains 41.8 % of hydrocarbons. Thermogravimetric analysis of AIW was performed in the temperature range from 40 to 1000 °C at heating rates of 10, 15, and 20 °C /min in argon medium (75 ml/min). The kinetic parameters were determined by the model-free Friedman, Ozawa-Flynn-Wall, and Kissinger-Akahira-Sunose methods. The average activation energy values are in the range of 208.44 - 216.17 kJ/mol, they were used to calculate the thermo-dynamic parameters. The results indicate that the pyrolysis application will allow efficient con-version of AIW into value-added products.
