摘要:The subject of the studies were waste generated in suburban households, in 3-bag system.The sum of wastes generated during the four analyzed seasons (spring, summer, autumn, winter – 1 year), in the households under study, per 1 person, amounted to 170,3 kg (in wet mass basis).For 1 person, most domestic waste was generated in autumn – 45,5 kg per capita and the least in winter – 39,0 kg per capita.The analysis performed of sieved composition (size fraction) showed that fractions: >100 mm, 40–100 mm, 20–40 mm constituted totally 80% of the mass of wastes (average in a year).The lowest fraction (<10 mm), whose significant part constitutes ashes, varied depending on the season of year: from 3.5% to 12.8%.In the morphological composition of the households analyzed (on average in 4 seasons), biowastes totally formed over 53% of the whole mass of wastes.A significant part of waste generated were also glass waste (10,7% average per year) and disposable nappies (8,3% average per year).The analysis of basic chemical components of biowastes showed that in case of utilizing them for production of compost, it would be necessary to modify (correct) the ratios C/N and C/P.Analysis of the chemical composition showed that the biowastes were characterized by very high moisture content and neutral pH.
