Royal Roads waste diversion at 72%


An updated waste audit was completed on campus between Thursday, April 25 and Thursday, May 16 to determine Royal Roads’ waste diversion, i.e., the amount of waste diverted from landfill.

During the audit, a total of 340 bags of garbage, mixed paper, recyclables, refundables, soft plastics and compost were weighed. Of those bags, a total of 94 bags were opened, sorted and analyzed. With the data gathered from this, the overall waste diversion rate is 72%. This signifies a 3% improvement from 2016.

Compost comprises the majority of the waste produced on campus at 51%, followed by garbage at 28% and recycling at 21% (Figure 1).

A high level of contamination (where items are incorrectly disposed) was observed during the audit. Specifically, the garbage stream had only a 37% proper disposal rate, while the mixed paper stream had 83% proper disposal and recyclables had 49% proper disposal.

A big thank you to all who helped with the collection, sorting, weighing and analyzing of the waste during the audit.
