Do you have a drawer or box filled with old laptops and smartphones? Or  perhaps your electric vehicle is reaching the end of its life and you're  shopping for a new one? What happens to the lithium batteries powering  each of these machines? Ajay Kochhar has an answer. He and fellow battery expert Tim Johnston launched Li-Cyle — a startup devoted to  recover critical materials from lithium-ion batteries and reintroducing  them back into the supply chain. That way, they're not just sitting  around in landfills — or worse — seeping materials into the earth. Also,  they're reducing the need for mining, which takes a devastating toll on  human lives.

Tune in to learn how University of Toronto alum Ajay  wields his clean tech company to not only solve the global battery  problem, but recycle those important battery ingredients back to the  manufacturers that need them. And discover what you can do to help!
