This dataset is for Black Cart and garbage bin waste from residential dwellings. The single family sector results represent the pooled average of samples of 20-25 residences collected in 18 communities in each of the four seasons of 2019 (72 samples). The communities sampled were selected to collectively represent the range of housing types and demographics in Calgary. The multi-family results represent garbage bin waste from multi-family complexes, and represents the pooled average of samples in each of the four seasons of 2019 (40 samples). The multi-family developments sampled included both low rise and high rise types, and all were customers of The City’s Commercial Collections service.
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.
