FIELD: chemistry.
SUBSTANCE: method for producing compost based on sewage sludge includes wastewater treatment with actinomycete Str. chromogenes sg 0832, mixing the resulting sediment with sawdust tree species and keratin waste - bird feather, further aerobic composting of the mixture. Sizes of sawdust are 2–5 mm, and keratin wastes are 5–10 cm. Mass ratio of sawdust, keratin wastes and sewage sludge is 2:0.5:1, respectively.
EFFECT: invention provides a reduction in composting time and an increase in the fertilizer value of the final target product.
