Methodology
The Citizen Satisfaction survey is a telephone survey conducted with a randomly selected sample of Calgarians aged 18 years and older. The survey is conducted on an annual basis.
The data are weighted to ensure the overall sample’s quadrant, ward, and age/gender composition reflects that of the actual Calgary population aged 18 or older according to Municipal and Federal Census data. Weights are included in the dataset.
Annual Waste Volumes provides the number of tonnes of material managed at City of Calgary landfills, through the residential Black (garbage), Blue (recyclables), and Green (food and yard waste) Cart programs, and Household Hazardous Waste program.
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. For more information please visit: Green cart composting
Annual Black Cart Waste Collected per Household is the average amount (in kilograms) of garbage collected by residential collection crews from each single family household.
Per cent of Residential Waste Diverted from Landfill Through Blue and Green Cart Programs represents the per cent of residential waste that is diverted from landfill through the Blue Cart and Green Cart programs, out of the total waste generated by single-family households. Since the Blue Cart Program was first implemented in 2009, the program continues to receive less material as packaging types change and printed materials decline. The Green Cart Program was implemented in the second half of 2017, and was completed in conjunction with a change from weekly to every other week Black Cart collection.
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 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. The weight per cent composition is provided for a number of material categories and subcategories.
