Colorado has drawn a line. With the stroke of a pen in early June 2026, Gov. Jared Polis turned what had been a growing headache for auto recyclers and scrap yards into a formal obligation for the companies that build electric vehicles. The new statute, Senate Bill 26-003, expands the state’s existing Battery Stewardship Act to cover propulsion batteries. Those are the large packs that power EVs and hybrids. Automakers must now collect, manage, reuse, repurpose or recycle them. No more leaving the mess for someone else.
The law prohibits disposal of these batteries in landfills after July 1, 2029. It sets concrete recovery targets that recyclers must hit by 2031: 90 percent for cobalt and nickel, 50 percent for lithium. That lithium figure climbs to 80 percent by 2035. These aren’t suggestions. They come with reporting requirements, labeling rules and fees paid by the manufacturers themselves. And the measure passed with bipartisan support. Even the auto industry backed it.
Why now? More than 200,000 EVs already cruise Colorado roads. Battery packs can weigh over 1,000 pounds. They contain valuable materials but also pose fire risks and storage problems. A salvage operator in Commerce City put it plainly to CPR News. “You have got to do something with these batteries,” said Norman Wright of Stadium Auto Parts. “If they can’t be reused or remanufactured, it ends up here. And what do we do with it?”
Before this law, the answer was often uncertain. Smaller operators lacked the scale to ship heavy packs economically to specialized recyclers. Larger players could absorb costs. The imbalance left some batteries lingering in yards or, worse, heading toward improper disposal. That ends here. The statute shifts the burden upstream. Manufacturers must create a statewide collection system. They pick up unwanted batteries from dismantlers, mechanics and solid-waste facilities at no charge to those handlers.
The Union of Concerned Scientists called the measure historic. In a post signed June 11, 2026, researcher Jessica Dunn wrote that it “will set the standard for the rest of the country.” The blog post on the UCS site details how the law requires third-party documentation of a battery’s state of health. This transparency helps decide whether a pack should power a second-life application such as grid storage before materials get recycled. Labeling must include manufacturer, chemistry, capacity and safety data starting in 2029. Those details matter. They reduce risks during handling and improve sorting for reuse.
Recovery targets focus on intermediate processing steps. Recyclers must achieve the percentages at the black mass stage rather than final refined products. This approach, according to the UCS analysis, discourages high-emission smelting methods that recover less lithium. Instead it favors processes that preserve more material value. Redwood Materials, a major U.S. recycler, praised the outcome-based standards in a June 11, 2026 post on X. The company noted the law prioritizes repurposing before recycling and preserves direct relationships between manufacturers and recyclers.
Producers register with the Colorado Department of Public Health and Environment by July 1, 2027. They submit stewardship plans by early 2029. Annual reports follow, covering collection volumes, recovery rates, reuse percentages and explanations for any uncollected batteries. The state compiles this data and surveys program effectiveness. Manufacturers cover oversight costs through fees scaled to their share of registered vehicles in Colorado. Those details come straight from the bill text on the Colorado General Assembly site.
Compare that to other efforts. New Jersey passed battery management rules but stopped short of specific mineral targets. A similar California bill in 2024 faced a veto. Colorado now leads. Waste Dive reported on May 28, 2026, with an update after the June 3 signing, that the statute marks the first EV-specific extended producer responsibility law with numeric recovery rates for nickel, cobalt and lithium. Danielle Spalding of recycler Cirba Solutions told the outlet the requirements align well with existing processes. The Automotive Recyclers Association highlighted improved safety for its members and clearer market signals for second-life batteries.
Economics play a central role. Lithium, nickel and cobalt prices fluctuate. Some packs cost more to recycle than the recovered metals fetch. NPR examined this tension in a July 2026 piece on EV battery economics. Without mandates, profit-driven decisions might favor landfilling or export. The Colorado framework removes that option after 2029. It also creates demand for better recycling technologies. The International Energy Agency has projected that recycled materials could supply 20 to 30 percent of future lithium, nickel and cobalt needs by 2050. Keeping those atoms domestic reduces reliance on new mines and vulnerable supply chains.
Yet challenges remain. Collection infrastructure must scale. Fire safety protocols become mandatory in plans submitted for 2030. Remanufacturers and entities that repurpose batteries for non-vehicle uses face their own compliance steps. The law spells these out explicitly. Commercial handlers who take possession of a pack for sale, repair or recycling must follow documented procedures. No one slips through easily.
Supporters see broader ripple effects. Jessica Dunn at UCS noted in the group’s analysis that widespread adoption of similar rules could meet roughly half of U.S. lithium demand for EVs in 2050 through recycled content. That figure assumes steady progress in recovery efficiency. It also assumes batteries returned from the road match the chemistry of new packs coming off assembly lines. Chemistry shifts toward lithium-iron-phosphate in some models complicate recovery economics since those packs contain no nickel or cobalt.
The Engadget article published on the day the law took effect laid out the stakes. Author Will Shanklin described the legislation as a potential blueprint. Automakers shoulder responsibility because they designed the product and profited from its sale. State Sen. Lisa Cutter, a co-sponsor, offered a straightforward explanation to NPR. “Producer responsibility just means that the people making the trash — or whatever we’re considering the trash, the thing we’re disposing of — have to take responsibility for recycling it and for taking care of end-of-life. There’s not a magic trash fairy. We have to plan for these things.”
Industry voices echoed measured approval. Nick Steingart of the Alliance for Automotive Innovation told UCS the bill supports supply chain resilience. Redwood Materials emphasized that end-of-life batteries represent assets, not waste. They can store energy or yield critical minerals. The law’s emphasis on documentation and health metrics should accelerate second-life markets. That extends battery usefulness before any material recovery begins.
Implementation will test the framework. The Department of Public Health and Environment must review plans, enforce targets and manage the fee structure. Battery stewardship organizations, already operating for smaller cells under the 2025 law, will adapt to handle these far larger and more complex packs. Retailers cannot sell non-compliant vehicles or batteries after certain deadlines. The system aims for accountability at every link.
Critics might argue the targets arrive too late or prove too modest. Lithium recovery starts at 50 percent. Some advanced hydrometallurgical processes already exceed 90 percent across metals. But the law sets a floor that applies statewide. It forces investment. And it creates data. Annual reports will reveal exactly how many batteries return, how many get repurposed and where material losses occur. Policymakers elsewhere can study those numbers.
Other states watch closely. Earthworks published an update on July 14, 2026, noting Colorado’s approach surpasses prior efforts by requiring mineral recovery reporting and easing reuse barriers. Western Resource Advocates helped shape the bill alongside UCS. Their collaboration produced a measure that balances environmental goals with practical industry needs. Bipartisan passage suggests the formula can travel.
Battery fires at recycling facilities and waste sites have made headlines in recent years. The law’s safety planning requirement from 2030 directly addresses that risk. Detailed labeling helps first responders and handlers. Third-party health assessments reduce guesswork about whether a pack still holds value. These provisions accumulate into something larger than a simple recycling mandate. They build a transparent, traceable system for an entire product category that barely existed two decades ago.
The carbon math favors action. Battery manufacturing remains the dominant emissions source for EVs over their lifetime. Recycling closes the loop. It cuts the need for virgin materials whose extraction carries its own environmental costs. The IEA data on future supply potential underscores the scale. If Colorado’s model spreads, national impacts could compound quickly.
Of course, success depends on execution. Automakers must invest in collection networks that reach rural dismantlers as well as urban ones. Recyclers need capacity to meet rising volumes as early EV fleets age. Technology must advance to hit the lithium targets economically. But the statute creates the incentives. It removes the free-rider problem that let some actors avoid costs while others bore them.
Colorado didn’t wait for Washington. It acted while national policy debates continue. The result stands as the most comprehensive state-level attempt yet to manage EV batteries from cradle to grave, or at least from road to refinery. Other legislatures will cite it, copy it or improve upon it. For now, the responsibility sits where proponents say it belongs. With the companies that put those heavy, valuable, complicated packs on the road in the first place.
