Ask HN: Is recycling lithium virtue signaling or greener/cheaper than mining?

8 pointsby brntsllvnover 2 years ago
The price of lithium carbonate is skyrocketing in response to demand for EVs (especially following the Inflation Reduction Act&#x27;s EV tax incentives): https:&#x2F;&#x2F;www.axios.com&#x2F;2022&#x2F;09&#x2F;21&#x2F;lithium-prices-electric-vehicles-evs. Solid state batteries may reduce but not eliminate demand.<p>Ridwell is the only startup I can think of offering battery recycling as a service and it&#x27;s just a fraction of their overall model.<p>Is lithium recycling from consumer electronics viable? &quot;Green&quot; in both senses of the word.

Redwood Materials (Founded by Tesla’s ex-CTO &amp; cofounder JB Straubel) has agreements with Ford, Volvo, and Toyota and currently recycles 6GWh of cells annually [1] [2]<p>Sourcing from recycled cells is cheaper than mined inputs. With that said, batteries last much longer than anticipated [3] [4], so while it’s environmentally responsible to recycle end of life cells (versus landfilling or them ending up in an incinerator), they won’t be a significant material stream for some time.<p>[1] <a href="https:&#x2F;&#x2F;www.redwoodmaterials.com&#x2F;news&#x2F;redwood-materials-creates-the-first-pathways-for-end-of-life-electric-vehicles-kicks-off-in-california" rel="nofollow">https:&#x2F;&#x2F;www.redwoodmaterials.com&#x2F;news&#x2F;redwood-materials-crea...</a><p>[2] <a href="https:&#x2F;&#x2F;www.autoweek.com&#x2F;news&#x2F;green-cars&#x2F;a40613774&#x2F;redwood-materials-recycling-vw-ev-batteries&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.autoweek.com&#x2F;news&#x2F;green-cars&#x2F;a40613774&#x2F;redwood-m...</a><p>[3] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=32758881" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=32758881</a><p>[4] <a href="https:&#x2F;&#x2F;www.forbes.com&#x2F;sites&#x2F;carltonreid&#x2F;2022&#x2F;08&#x2F;01&#x2F;electric-car-batteries-lasting-longer-than-predicted-delays-recycling-programs&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.forbes.com&#x2F;sites&#x2F;carltonreid&#x2F;2022&#x2F;08&#x2F;01&#x2F;electric...</a>

Unless we can find a technology that seriously reduces or eliminates the need for lithium, recycling it will be mandatory or we&#x27;ll simply run out.<p>How long it will be before we&#x27;ve used up the earth&#x27;s lithium supply is very much in debate. It depends on how large the demand will be, which is a thing we can only speculate about.<p>But current estimates range from 20 to 200 years.

I don&#x27;t know about whether lithium recycling supply chains are better or worse than lithium mining supply chains from an environmental or GhG perspective but there is no doubt a great deal of academic literature on the topic, as there is for all other economically significant metals. I do however know that the numbers for steel production are heavily in favor of recycling, if that helps.<p>Prices, being social constructs, have very little to do with the green attributes (or lack) of any traded commodity.

Lithium is not viable long-term. In the short term it is, and the great fallacy of our time is that it is renewable. There are even memes on TikTok of people charging their Teslas with a petrol generator if you care to look.<p>The only real way to solve this is mining space asteroids which contain <i>much</i> more (rare) precious metals than our earth can provide.

Nothing is &#x27;virtue signaling&#x27;.<p>It&#x27;s not a real thing.<p>If you can rephrase the question without using that phrase then you should. If you can&#x27;t rephrase the question without that phrase then you&#x27;re not asking anything that can be answered.
