It’s Time to Get Toxic Chemicals Out Of Dry Cleaning

Perchloroethylene, a probable human carcinogen, remains the most frequently-used solvent for dry cleaning. It's time to help the industry change—and our county is doing just that.


When perchloroethylene (PERC) was introduced to the dry cleaning industry in the 1930s, it must have seemed like a miracle solvent.

It cleans clothes well and – most importantly – it is nonflammable. This is in contrast to the previous solvents, like Stoddard solvent, gasoline, turpentine, and even benzene. Because the use of these flammable solvents resulted in catastrophic fires and explosions, government regulations forced dry cleaners to move out of highly populated areas. With the advent of PERC, dry cleaners could move back to population centers, where the customers were.


The dry cleaning industry provided a unique opportunity for a whole generation of immigrants. A 2011 survey indicated that in King County, Washington, for instance, more than 80% of dry cleaning business owners emigrated from South Korea. For many of these immigrants, dry cleaning was the ideal business. They readily grasped the complexity of the dry cleaning process and were able to build successful businesses through hard work.


Unfortunately, very few are aware of the health risks associated with a lifetime of using a hazardous chlorinated solvent.


Old machines, hazardous exposures 


The earliest dry cleaning technology used "transfer machines," where fabrics washed in PERC were manually transferred to dryers while still wet. The exposures to PERC were massive, and several epidemiological studies suggest excess risk for cancer and adverse effects on the nervous system, kidneys, liver, immune system and the hematologic (blood) system.


Although transfer machines are now banned in the United States and replaced with enclosed "dry-to-dry" machines, we still see PERC exposures. In King County, most PERC machines are more than 20 years old, which is past their operational lifespan of 15 years. These old machines are leaking. We have measured hundreds of parts per million of PERC in the ambient air of dry cleaners.


Workers are also exposed to PERC when they remove fabrics from the machine, handle their hazardous waste, and deal with accidental spills.


Here in King County, the Local Hazardous Waste Management Program has provided technical assistance to the dry cleaning community for more than 20 years.


When we considered the legacy of PERC's effects on health and the environment, we realized that we needed to get PERC out of dry cleaning.


There are almost 200 sites in King County contaminated with PERC. In addition, some of our local communities draw their drinking water from shallow aquifers, which contain detectable levels of PERC. The U.S. Environmental Protection Agency (EPA) is currently evaluating PERC for possible restriction, so we recognized an opportunity to help dry cleaners switch to safer alternatives – and avoid "regrettable substitutes" – ahead of potential federal regulations.


Making the switch


Several jurisdictions have already taken steps to remove PERC dry cleaning machines from circulation. The California Air Resources Board (CARB) passed a regulation in 2007 phasing-out PERC dry cleaning by 2023. The Cities of Philadelphia and Minneapolis have also passed phase-outs.


Other jurisdictions have given tech and financial support to help dry cleaners switch to safer alternatives, including Massachusetts (via the Toxics Use Reduction Institute), New York State, the South Coast Air Quality Management District, and the City of Minneapolis.

We engaged our dry cleaning community to find out what it would take to help them switch. We worked with leaders in the Korean-American community to host meetings of the local dry cleaning association, facilitated focus groups, and conducted numerous interviews with dry cleaners – all in Korean. We learned that cost was the single greatest barrier to replacing old PERC machines with safer technology.


In 2018, we began offering $20,000 equipment reimbursement grants to help dry cleaners replace their PERC machines with professional wet cleaning, which relies on water and detergent, rather than an organic solvent.


The latest generation of professional wet cleaning is an integrated system, comprised of a programmable washer, a moisture-sensing dryer, and specialized detergents and conditioners that allow any "dry clean only" fabric to be washed in water.


So far, we have provided grants to seven dry cleaners — and all seven are no longer inhaling PERC. Some workers are reporting significant improvements in their health. Shop owners are also saving money because they no longer generate hazardous waste and their utility bills are much lower.


Our goal is to make King County PERC-free by 2025 by offering 10 grants of $20,000 per year.

Providing grants to small businesses is a positive step in helping eliminate dangerous chemical exposures that impact the health and environment in our communities.

Stress levels are high for CPG companies and packaging groups as extended producer responsibility programs unfold in multiple states. This was on display at three recent Boston events hosted by the Sustainable Packaging Coalition, How2Recycle and the Northeast Recycling Council, with questions flying about costs, policy harmonization and relationships with regulators. Paul Nowak, executive director of GreenBlue, adopted the role of support group leader for a room full of representatives from many of the world’s largest CPG companies in his opening talk at SPC Advance. He reminded them that “you are not alone” and urged them to take the long view on this major industry shift. “What you see at the end of the change is not what you see during the change,” said Nowak, drawing on examples from prior industry shifts as well as other major life events. “You are in this uncomfortable period right now where it’s not moving as rapidly as you would think and you don’t have the historic perspective yet of where it could go.” Sticker shock While CPGs are familiar with EPR costs from programs in other countries, the complexity and scale of the U.S. rollout in seven states is presenting its own unique challenges. Oregon is the only state that’s begun collecting fees, and already the costs are high. Circular Action Alliance, the producer responsibility organization selected for the majority of state programs to date, estimates a budget of $188 million in the program’s first year, with that figure growing in the years ahead. Charlie Schwarze, board chair for CAA and senior director of packaging stewardship at Keurig Dr Pepper, said the costs are starting to resonate with major companies. KDP, for example, has been working to sort out different aspects of its packaging in terms of licensing arrangements, private label manufacturing partnerships and other factors. This requires a close relationship with the company’s finance, R&D and procurement teams to gather data and make cost projections. “It’s been a bit of a slow-moving process because the dollars, at least in 2025, are not extremely notable. But they’re going to get bigger pretty quickly,” he said, citing Colorado and California’s programs on the horizon. Shane Buckingham, chief of staff at CAA, said it will be months until companies have a better sense of the true costs. The group set initial fees for California, which won’t be invoiced until August 2026, but those fee levels are expected to change once SB 54 regulations are finalized . “Please don’t take our early fee schedule of being indicative of what your cost will be in 2027, it’s just a drop in the bucket,” he said. “The fees are going to go up significantly in California because we have to fund a $500 million [plastic] mitigation fund, we’re going to have system funding to improve recycling, source reduction, reuse, refill.” SPC Director Olga Kachook encouraged attendees to think about these fees as motivation to innovate rather than a burden. In her view, avoided fees through ecomodulation could be viewed as “possible new investment capital” for covering the costs of material switches, R&D, MRF testing, consumer education campaigns and more. “We can innovate to those lower fees by switching to incentivized materials and formats and then we can reinvest the savings back into sustainable materials and infrastructure that seemed out of reach,” she said. Searching for harmony All three events also featured ample discussion about if or how aspects of current EPR programs could be better aligned. While regulators are working to align certain definitions where possible, they also noted that certain state programs were uniquely designed for a reason. David Allaway, senior policy analyst at the Oregon Department of Environmental Quality, said during NERC’s Rethink Resource Use Conference that he sees a potential benefit to harmonizing ecomodulation approaches in some cases. But at the same time, he said, “I fear that the push for harmonization will lead to a race to the bottom” by potentially limiting the ability for states to craft policies based on their respective needs. As for those who critique other unique aspects of Oregon’s law, such as responsible end market requirements , Allaway said “that’s not negotiable for us,” as market issues were a leading motivation for the law in the first place. Allaway said Oregon’s system was established based on specific regional priorities, such as putting an end to exporting certain types of material that led to dumping in other countries. The state’s approach to ecomodulation and life cycle analysis is also informed by years of work on greenhouse gas inventories and consumption-based accounting, which challenges many commonly held assumptions about recyclability . Each state has its own unique factors in terms of collection access and market infrastructure. Colorado, for example, has many areas that will be getting recycling service for the first time. Maine also has many rural areas that previously had access to recycling but lost it in recent years. Meanwhile, in Maryland, collection service may be more common but local end markets are lacking for certain commodities. Jason Bergquist, vice president of consulting firm RecycleMe, said during the NERC event that he hears concerns from clients about where this is all headed. “If we get to a couple years down the road and we’ve got, let’s just pretend, 25 states with EPR, with different deadlines, different [covered material] lists, different definitions, different ecomodulation — my concern as a fan of EPR is that the pushback will be so significant that it could get existential for the producers,” he said, in terms of costs and compliance management. At the same time, Bergquist said the experiences of packaging EPR in Europe and Canada show it may take years to get toward any kind of harmonized system. Back at SPC Advance and the co-located How2Recycle Summit, California loomed large throughout the week when it came to these questions. Karen Kayfetz, chief of CalRecycle’s product stewardship branch, said regulators from different EPR states try to talk to one another as much as possible but in some cases they’re limited by the statutes that created these programs. “We each have our own legal frameworks we have to work within,” she said. “So harmonization starts with the legislatures, and that is not our responsibility, but it is something that we could see change and evolve over the coming years.” As all of these complex questions get worked out, Kayfetz reminded attendees that CalRecycle may currently be “the face” of the program but that’s not the long-term goal. “What would make me the happiest is if you leave here thinking ‘let’s go talk more to CAA.’ Because EPR is a policy mechanism that is meant to be a public-private partnership where the public entity ... is overseeing the PRO,” she said. “They are your partner and we are their police.” In a separate session, CAA’s Buckingham described the work of ramping up different state fee and reporting programs as building a plane while flying it. The group is working to streamline its own reporting processes as much as possible, but they and others anticipate things will only get more complicated in the near term. “2026 will bring with it a new set of EPR laws and recycled content laws,” predicted KDP’s Schwarze, “and they’re going to be different than what we have right now.” Read on Packaging Dive.

In the Northeast, recycled commodity prices continued to decline in April-June, with MRFs experiencing an average decrease of nearly 6% compared to the first quarter of 2025, according to the Northeast Recycling Council’s (NERC) second-quarter MRF Values Survey Report. NERC’s 25th quarterly report analyzed data from 19 MRFs across 12 states, excluding two facilities from the average blended value “because they did not market enough commodities within Q2 to provide a representative comparison with other MRFs.” Compared to the previous quarter, the responding MRFs reported average values per ton for blended recyclables with residuals at $82.68, a decrease of 7.74%, or $96.21 per ton, a 5.99% decline without residuals. Thirteen of the 17 MRFs contributing to the weighted average were single-stream, while four operated on a dual-stream/source-separated basis. In the Northeast, dual-stream facilities reported a blended value of $99.74 without residuals and $86.52 including residuals, experiencing decreases of 7% and 7.16% from the previous quarter, respectively. Single-stream MRFs recorded blended values of $95.08 without residuals, down 5.7%, and $81.28,down 8.3%, with residuals. Factors such as tariffs and weak demand have led major waste haulers to adjust their forecasts, anticipating challenges due to economic uncertainty for the remainder of 2025. This dip in commodity prices was reflected in second-quarter earnings reports, with four companies reporting an average year-over-year decrease of 15% in commodity values. Houston-based WM projected a $15 million decline in earnings before interest, taxes, depreciation, and amortization due to softening demand. However, the emergence of new and upgraded polymer facilities is enhancing processing capabilities, driven by the expectation of high demand for recycled PET.
