Redwood has been getting a lot of press lately over their potential $2 billion dollar loan (https://www.forbes.com/sites/alanohnsman/2023/02/09/redwood-...), but what shocks me with this is how low volume their process is now. I talk a lot about scale and volume in recycling - but 250NT of material is nothing. Some large car shredders generate that much in fluff/ADC in a day, and there are dozens of them operating around the country.

We recycle about 12 million cars a year in the US - https://en.m.wikipedia.org/wiki/Vehicle_recycling - this is 1,268 cars worth of batteries. We have a long way to go!

I think this says a lot about how exaggerated the discussion around EV battery failure rates is.

Older Nissan Leafs are still on the road: https://cleantechnica.com/2022/09/21/surprise-nissan-leaf-ba...

Nissan’s CEO said the batteries are outliving the cars. Old battery packs are usually repurposed as stationary storage versus being shredded and recycled.

Redwood spinning up when the need is low is better than waiting until the need to dispose of packs and for manufacturing feedstock is high.

When they talk about Damage Defective Return being under 5% - that is major failures. When it’s not DDR - it’s in the same form it was from the OEM
