Quantitive and qualitative analysis of household waste - comparison of official data and results of case study

Statistical data of household waste management and relevant data found by one year long direct survey at five households were compared. While the composition of residual (mixed) household waste is determined by sieve analysis and manual aftersorting to predetermined groups (and the material composition of waste that passes through a sieve mesh of 8x8 mm openings is not detected by this analysis), during the direct survey in households all the household waste is sorted to predetermined groups. Official information systems report that average total amount of household waste is 301 kg per person and just less than 4 % of it is sorted to usable fractions. The direct survey shows that avarage total amount of household waste is just 164 kg per person and it is possible to sort 63 % of it.
