METHOD FOR PROCESSING ORGANIC WASTES IN ENVIRONMENTALLY FRIENDLY RAW MATERIALS Russian patent published in 2019 - IPC C05F3/00 

FIELD: waste processing and disposal.

SUBSTANCE: invention relates to methods of processing organic wastes. Method involves preparation and treatment of organic material. Preparation is carried out by grinding and mixing of organic wastes to obtain homogeneous mass with size of solid particles of 0.1–5.0 mm and relative humidity with coefficient of liquid module of not less than 0.1. Treatment is carried out by disinfection and subsequent neutralization of the obtained homogeneous mass of organic wastes. Disinfection is performed by adding a solution of hydrogen peroxide and nitric acid and/or orthophosphoric acid. Total pH of the pH solution is 0.5–6.0. Mixing is then carried out, oxidizing potential of the mixture is measured and stirring is continued until the oxidative potential is changed by more than 0.1 V from the initial one. Neutralization is performed by addition of ammonium bicarbonate or food chalk into disinfected mixture with stirring till mixture pH is 6.0–7.0.

EFFECT: invention enables to obtain environmentally clear safe raw material from organic wastes for production of fertilizers, fodder or fodder additives.
