FIELD: environment protection.
SUBSTANCE: invention relates to a method for obtaining a sorbent for collecting oil and petroleum products by grinding Sosnovsky hogweed, drying the crushed raw materials at a temperature of 270-350°C, a pressure of 1.1-3.5 atm for 2.5-3.0 hours and subsequent thermal carbonization of the drying product in the open air at a temperature of 300-600°C for 10-15 minutes to obtain the target product with the particle size of 0.3-5.0 mm.
EFFECT: expansion of the range of solutions for waste treatment.
