METHOD FOR MAKING A BIODEGRADABLE PLANT GROWING CONTAINER Russian patent published in 2022 - IPC A01G9/29 

FIELD: crop production.

SUBSTANCE: invention relates to the field of crop production and can be used for growing seedlings of various plants. A method for manufacturing a biodegradable container for growing plants is as follows. sewage sludge, sawdust and a binder - a polysaccharide, such as wheat flour, are mixed in the following ratio, wt.%: sewage sludge - 65-70, sawdust - 15-20, polysaccharide - 15. Then water is added to the resulting mixture in an amount that ensures the final moisture content of the mixture is 55-60%. The mixture is placed in a mold, cold pre-pressing is carried out for 2-3 minutes, and then it is dried in an open mold at a temperature of 65°C in an oven to a moisture content of 6-8%.

EFFECT: invention provides a container that quickly decomposes in the soil, retains moisture well, preventing plants from drying out, while the organic composition of sewage sludge accelerates seed germination, and also serves as an additional source of nutrients for plants, in addition, the use of sewage sludge and sawdust as the main components for the production of a biodegradable container also solves the environmental problem of their disposal.
