California, Florida, Nevada, Washington, and Massachusetts all tried — and failed — to pass comprehensive EV battery recycling laws. Colorado quietly succeeded where they couldn’t. Governor Jared Polis signed SB 26-003 on June 3, 2026, making Colorado the first U.S. state to adopt a comprehensive extended producer responsibility (EPR) framework for EV battery propulsion batteries — a structure that makes manufacturers legally responsible for what happens to their products at end of life. With no federal standard on the horizon, that’s not a small thing.
Automakers Pick Up the Tab – Literally
The law compels manufacturers to collect spent battery packs from scrap yards, mechanics, and dismantlers at zero cost to those businesses.
Landfill disposal is banned starting July 1, 2029. Batteries must be reused or repurposed first — stationary energy storage is one practical second life — with recycling as the last resort. Automakers must also make battery state-of-health data accessible to third parties while the pack is still in the vehicle, so downstream businesses can decide whether a battery is worth salvaging or ready for processing. That transparency requirement alone reshapes how the used-battery market functions.
What the law actually requires:
- Manufacturers register with Colorado’s Department of Public Health and Environment by July 1, 2027
- Landfill disposal of propulsion batteries banned July 1, 2029
- By 2031: recyclers must recover 90% of cobalt and nickel, and 50% of lithium
- Lithium recovery target rises to 80% by 2035 — steering investment away from traditional smelting toward hydrometallurgical processes, which use water-based chemistry to extract metals at higher recovery rates
- Annual reports due each June starting 2030, covering collection numbers, recovery rates, and reuse versus recycling share
Western Resource Advocates frames the stakes plainly: the framework will “reduce the demand for mining and prevent unnecessary damage to habitats and landscapes.”
Those recovery targets carry real technical weight. The Union of Concerned Scientists notes that the 80% lithium threshold by 2035 effectively rules out traditional smelting, which tends toward lower recovery efficiency and higher emissions for certain elements. That steers capital toward better technology. Meanwhile, Wood Mackenzie projected that enough used batteries won’t exist for large-scale recycling until around 2030 — Colorado’s mandatory collection system directly attacks that feedstock problem.
Automakers like Audi, BMW, Ford, Toyota, and Volkswagen already have recycling deals with Redwood Materials. But contracts without a collection mandate behind them remain aspirational. Colorado closes that loop.
A Blueprint, Not Just a State Law
Colorado’s real value is as a replicable template — complete with manufacturer-funded oversight and public reporting requirements.
The Automotive Recyclers Association calls the framework a “no-cost, turnkey solution” for recyclers holding batteries they can’t reuse or repurpose — reducing fire risk and liability for small businesses in the process. Manufacturers fund state oversight through fees tied to their share of registered propulsion-battery vehicles in Colorado. The Colorado Department of Public Health and Environment will survey program effectiveness and publish results, giving every other state real-world data on whether an EPR-based EV line battery system actually performs.
The compliance timeline runs to 2035. The reporting data Colorado generates will be the first state-level evidence of this model in practice. Other states will be watching. So will automakers.
