Waste Composition studies are periodically conducted by Waste and Recycling Services to help assess the performance of diversion and education programs and inform improvements and new program design. This dataset is for Green Cart waste from residential dwellings, and represents the weighted average of samples of 20-25 residences collected in 22 communities in each of the four seasons of 2020 (88 samples). The communities sampled were selected to collectively represent the range of housing types and demographics in Calgary. The weight per cent composition is provided for a number of material categories and subcategories.
