FIELD: biotechnologies.
SUBSTANCE: sub-standard carbamide-formaldehyde resin after its service life with the help of composting in mixture with waste waters sludge - poultry manure, swine manure, cattle manure and wood chips can be used at the plants producing resins for chemical, wood-processing, furniture and construction industries.
EFFECT: possibility to utilise three types of wastes simultaneously: waste waters sludge, wood chips, resin obtained at production of resin-bonded chipboard and simplify, make cheaper the technology of obtaining organic-mineral fertilisers and improve the fertilising value of the end target product.
