Zhodnocení aktuální kvality biologicky rozložitelného komunálního odpadu tříděného občany města Kroměříž

Abstract

In an effort to meet the requirements for maximum material utilization, which is set forth in the Act No. 185/2001 Coll. on Waste and amendments to other Acts, and to achieve the objectives of the Waste Management Plan of the Czech Republic to reduce biodegradable waste going to landfill, a proposal for widespread deployment of separate collection and processing of biodegradable municipal waste in municipalities has become part of the amendment Act prepared by the ministry. In many places of the country pilot projects have been launched to test the technology and logistics of sorting, collecting, processing and utilizing biodegradable municipal waste separated by residents.Separate collection of biodegradable municipal waste in Kroměříž was launched as a pilot project in 1992. Despite all the residents’ education, the management of Biopas is not satisfied with the quality of biodegradable waste separation; problems occur especially in the residential area. Biodegradable waste separated by residents, due to its unacceptable amount of impurities, is transported to the landfill Kuchyňky near the village Zdounky 10 km distant but detailed data on the amount of impurities in separate biodegradable municipal waste were missing.Therefore an analysis of separate biodegradable municipal waste has been carried out. Individual samples were collected within two days of separate waste delivery, without any modifications (scattering, compaction). The sample size was at least 200 kg, the sample was manually sorted according to the Catalogue of Waste into biodegradable waste (200201), other non-biodegradable waste (200203) and biodegradable waste unsuitable for composting (e.g. animal by-products). It was found that the amount of unacceptable impurities in separate biodegradable waste considerably varies from 1 to 9 %wt.It can be concluded that the amount of unacceptable impurities in biowaste is too large to allow composting and compost production (in 2009).
