The SummerFolk Festival is held at Kelso Beach Park, during August in Owen Sound Ontario. For this year’s 43rd SummerFolk, organizers partnered with the Grey Bruce Sustainability Network and Busch Systems to assist with a waste audit at the festival. The audit was performed during the festival with the primary goal of establishing a baseline of the current diversion rate and stream composition. During the entire festival 4,014 lbs. of refuse was generated. The SummerFolk Festival baseline diversion rate was 38%. This report reviews how much refuse was produced, where in the festival grounds and at what time. This report provides recommendations on how SummerFolk can work to achieve an 80% diversion rate or higher similar to other successful festivals.
