BIOLOGICAL DECOMPOSABILITY OF RAPESEED OIL AND RYE FLOUR PRODUCTIONWASTE IN THE MODELING EXPERIENCE

Abstract

The search for effective ways to dispose of waste of plant origin and the study of the processes accompanying their decomposition expand the prospects for reducing the negative impact of crop waste on the environment and contribute to the creation of new biodegradable materials and products from them that will be able to replace traditional, practically non-biodegradable polymers. The purpose of the model experiment was to study the processes of decomposition of waste of plant origin in a
soil substrate under the action of effective microorganisms (EM). The object of the study was waste from the production of rapeseed oil (husk) and rye flour (of complex
morphological composition). The characteristics of the fractional and morphological composition of rapeseed and rye waste, data from elemental and spectral analysis,
which showed significant differences in the chemical composition of waste samples before and after contact with soil, are presented. In the conditions of the model
experiment, it was found that after contact with a soil substrate containing effective microorganisms, the decrease in the mass of rapeseed and rye waste averaged 31,8% and 60,2%, respectively.
