Recycling of batteries and air bags.
Some chemicals are highly reactive or explosive at ambient temperature. Safe recycling of products containing these chemicals is of utmost concern. By cooling to cryogenic temperatures, such products are rendered relatively inert or desensitised.
SHEARING AND CRUSHING
Afterwards they can be sheared or shredded. The materials can be separated and recycled. Typical examples can be found in recycling of batteries and of the trigger component of air bags.
