Abstract: The article deals with a thermal decomposition of vineyard pruning waste. The samples were tested by means of thermogravimetry and differential scanning calorimetry in the flow of air and nitrogen. Thermal gravimetric analyses were performed up to a temperature of 650°C and differential scanning calorimetry up to a temperature of 600°C. The heating rates were 2°C.min−1, 5°C.min−1, 10°C.min−1, 15°C.min−1 and 20°C.min−1 in both cases. Values of activation energies were subsequently calculated from the obtained results using various methods. The maximum mass loss of the samples was observed in the temperature range from 297.5°C to 319.3°C in the case of test with air and in the case of test with nitrogen in the range between 330°C and 367.3°C. The values of activation energy of thermal decomposition in the air were higher than the values in the case of nitrogen atmosphere.
