The resultsshowed that residual household waste mainly contained food waste (42 ± 5%, mass per wet basis) and miscellaneous combustible (18 ± 3%, mass per wet basis).
The residual household waste generation rate in the study areas was 3–4 kg per person per week. Statistical analyses revealed that the waste composition was independent of variations in the waste generation rate.
Both, waste composition and waste generation rates were statistically similar for each of the three municipalities. While the waste generation rates were similar for each of the two housing types (single-family and multi-family house areas), the individual percentage composition of food waste, paper, and glass was significantly different between the housing types.
This indicates that housing type is a critical stratification parameter.
Separating food leftovers from food packaging during manual sorting of the sampled waste did not have significant influence on the proportions of food waste and packaging materials, indicating that this step may not be required.
