According to Environment Canada, approximately half of the mercury in the environment originates from natural sources and processes; the other half is from human activities.
Due to its unique properties, mercury is used in a variety of applications. It is the only metal that, when in pure form, is liquid at room temperature. Mercury conducts electricity and expands evenly in response to pressure or temperature changes. These properties have made mercury a widely used material in household, commercial, medical and industrial applications.
However, mercury is of concern because it is a toxic, bioaccumulative and persistent heavy metal that can have impacts on the environment and human health.
For this reason, Switch Out is dedicated to the removal, collection and management of mercury-containing convenience lighting switches and ABS sensors from end-of-life vehicles. The switches recovered through the national program are counted, documented, retorted and recycled.
