Proper disposal of flares is important as they cannot be thrown in the regular trash due to their safety hazards. The only real safe way to get rid of them is through someone licensed for explosives disposal.
Unlike other consumer products with special disposal procedures like tires or paint, there’s a lack of support from manufacturers to take in flares. C-I-L, the Canadian chemicals manufacturer, is one of the only companies accepting old flares, but only at select facilities in Eastern Canada.
Pacific Blasting, a Burnaby firm has been recycling expired pyrotechnic flares since 2009.
