It will probably amount to recycling credit schemes I am sure. But that would definitely boost lithium recycling efforts.
From memory over 1million disposable vapes are thrown away each day, from 500 of the bigger cell vapes a Youtuber was able build a home battery to power his house. I don't think 100% recycled makes sense but there sure is a lot of lithium getting thrown into the bin. Incentives to recapture that are good.
That's 730k households in a year. Cool but since these batteries will probably die within a year, then you are only able to cover 1.5 million people or so. I am not against it, but 1.5m in 8b is a drop in the ocean.
500? thats just 5x10x10, even the bigger cell vapes would result in a tiny battery to power a house...
