This study addresses a gap that exists in studying waste business characteristics and the performance of a waste management system (WMS). Temporal and spatial analyses of the WMS in four Western Canadian provinces are systematically assessed over a 16-year period. The average waste business size in Canada ranged from 13.4 to 22.1 employees per business. Jurisdictions with lower disposal rates generally have larger waste companies. An average employee handled 1098 to 1426 t of waste annually. The diversion rates tended to be higher when less waste is managed per employee, suggesting total employee count may be important to improve WMS sustainability in Canada. Waste transfer costs are substantial during the study period, totaled $1276 million annually, or about 40.7% of the total government waste spending. BC only spent an average of 2.5% of the budget on operation of recycling facilities, but has the highest waste diversion rate. Expenditure distribution alone is unable to explain BC's superior waste diversion performance. Capital expenditures have been increasing from $15.7/t to $26.2/t. In this study, a business with more full-time employees correlates well with higher operating revenues. Part time workers were more predominant in SK, and may be responsible for the subpar diversion rate and operating revenue. More research is needed to determine waste business characteristics given increasing interest in circular economy and WMS efficiency. • Waste management systems (WMS) in Canada are examined over a 16-year period • Capital expenditures increased gradually, with an average of $22.7/t • Total employee count may be vital to improve WMS sustainability in Canada • A business with more full-time employees correlates with higher operating revenues • Studies on business characteristics and their effect on WMS performance are limited [ABSTRACT FROM AUTHOR]
