FIELD: biotechnology.
SUBSTANCE: biodegradable composite material comprising a polymeric matrix based on waste formaldehyde resin and a filler comprising starch, yeast, casein glue, characterized by the filler containing sodium hydrogen carbonate in the following component ratio, by weight: waste phenol-formaldehyde resin SF-010 50.8-55.5, sodium bicarbonate 15.0-16.5, starch 11.0-13.0, casein glue 11.0-16.0, yeast 6.0-6.5.
EFFECT: biodegradable composite material is proposed that efficiently utilizes phenol-formaldehyde resins and their wastes by biodegradation with the aim of reduction of the hazard class of the disposed substances, without adversely affecting the soil.
