As a result of a 2016 Corporate Plan Initiative the City contracted S-Cubed Environmental to conduct two audits, one in summer and another in fall of 2016. Two audits were completed to account for the seasonal differences in quantity and composition of the materials, and to allow annual comparisons to be made from a wider source of data.
A sample of 100 houses were selected from several neighbourhoods representing City demographics and were classified as declining (18), status quo (23), single family (25), multi-housing (9) and growth (25). Single and row houses, as well as mobile homes, were included in the sample. The sample also included houses with the 120 litre garbage cart.
The material received was sorted and audited, with the contents of each bag being weighed and recorded. This data was used to determine the City's current waste diversion as well as to compare the City's diversion and programming with neighbouring municipalities.
