Abstract

Within the Canadian federation, provinces and territories are often thought of as labs for incubating new ideas and policies. With regards to waste management, this appears to be the case as some provinces and territories have vastly different systems and outcomes when compared to others. Further understanding these waste system differences and similarities as well as outcomes can help to spread best practices within Canada and abroad. Therefore, this study introduced a novel waste diversion indicator called the Diversion Size Indicator (DSI) and applied it to analyze waste systems across Canada. As a possible measure of efficiency in a waste system, results from the analysis show that Nova Scotia has the highest DSI of all jurisdictions studied at 16,316%, a rise of 17% from 1998 to 2014. All other jurisdictions had lower DSI from during the same period, with percentage decreases ranging from 44% to 73%. Using the coefficient of variation we found the greatest variability in the DSI in the Prairie Provinces of Manitoba, Saskatchewan, and Alberta, who all had a greater than 60% decrease in DSI. Median values of the DSI from 1998-2014 showed Prince Edward Island having a high DSI along with Nova Scotia and British Columbia, possibly revealing highly efficient waste management systems in the provinces. Utilizing this indicator can help improve the efficiency of waste systems, reduce the costs to citizens, and provide the impetus for waste firms to innovate and find ways to further reduce costs.
