Yes, significant progress is being made, both from a policy perspective in terms of developing that end-of-life requirement for recycling and also, from a technological perspective. There's been a lot of research going on in universities around the world, including here in Canada, looking at how we can actually be harvesting metals and minerals from electronic waste, including lithium-ion batteries used for electric vehicles, which accomplishes two ends.
One is that it prevents that waste stream from going into landfills and causing issues with contamination.
Second, it can prevent the same extent of new mining and extraction activity to make sure that we have the metals and minerals we need for producing these vehicles. Whether it's electric car batteries or solar panels, the clean energy sector is acutely aware of the life-cycle impacts of their products from extracting the metals and minerals required for them through to their end of life. For the clean energy sector, much of their reputation is built on environmental credibility, so it's something that they're looking at very closely. The European Union, in particular, and now also China, are moving very aggressively at looking at how to close that loop with the end of life of electric vehicle batteries.
