PRODUCTION OF COMPOST FROM TOWN WASTES IN POLAND
Lately by the Institute for Municipal Economy in Warsaw a modern technology of accelerated composting of town wastes was worked out and the construction of the necessary special equipment developed.
The technological process of compost production consists in a fully mechanized preliminary treatment of the wastes and in an acelerated controlled biochemical process in piles. The preliminary treatment comprises: segregation, crushing and two-stage cleaning from remainders of plastic foil, rags, glass, slag, etc.
Biochemical process leads to:
- sanitary neutralization of mechanically processed wastes under influence of high temperatures 65–70°C and of the formed antibiotic substance;
- decomposition of organic compounds and their transformation into humus.
The compost ready for use as a fertilizer is obtained after about 1.5 month while the heating compost - as early as after 3 weeks.
