Redwood Materials integrates recycling and manufacturing

The real line between old school recyclers and integrated players is where the chemistry stops. Companies like Li-Cycle and ABTC are built to turn spent batteries into black mass, metal salts, lithium carbonate, or mixed hydroxide products, which are useful feedstocks but still need another manufacturer to turn them into cathodes or anodes. Redwood pushes one step further by making battery components like cathode material and copper foil, which lets it capture more margin and plug more directly into cell factories.

• Hydrometallurgy and pyrometallurgy are extraction steps. In practice that means shredding or smelting batteries, separating out nickel, cobalt, lithium, copper, and graphite, then selling those outputs as intermediates rather than as finished battery parts ready to go into a new cell.

• Li-Cycle is the clearest example of the traditional model. Its Spokes produce black mass, then its Hub is designed to refine that into products like lithium carbonate and MHP. That closes the metals loop, but not the battery component manufacturing loop.

• The category is starting to blur. Ascend Elements explicitly positions itself beyond recycling by making pCAM and lithium carbonate, and ABTC has said it plans to move from selling black mass toward battery grade metal products. The market is shifting from waste processing toward domestic materials manufacturing.

Going forward, the winners in battery recycling are likely to look less like scrap processors and more like specialized materials plants. As North American cell factories scale, more value will sit with companies that can take in battery scrap and ship out battery ready components, not just recovered metals.
