The garment that comes back to you on a hanger looks the same whether it was cleaned with a solvent that contaminates groundwater or one that breaks down safely without leaving a toxic footprint. That difference is invisible at pickup. But it is significant in ways that extend far beyond the fabric of a single suit jacket, affecting the health of dry cleaning workers, the air quality in surrounding buildings, and the groundwater beneath the city.
The solvent a dry cleaning facility uses, how it manages chemical waste, and what operational choices it makes around energy and packaging all contribute to an environmental profile that varies dramatically from one operation to the next. In San Francisco, where environmental standards are among the most demanding in the country, the dry cleaner you choose is a genuine environmental decision.
The Problem With Traditional Dry Cleaning Solvents
For most of the twentieth century, the dry cleaning industry operated on a single solvent: perchloroethylene, universally shortened to perc. Perc became the industry standard because it dissolves oil-based soils effectively, does not react with most fabrics, and evaporates quickly after the cleaning cycle. The problem with perc is not its cleaning performance. The problem is everything else about it.
The United States Environmental Protection Agency classifies perc as a probable human carcinogen. The California Environmental Protection Agency goes further, classifying it as a known carcinogen under Proposition 65. The documented risks include:
- Elevated cancer risk, neurological effects, and reproductive harm from long-term occupational exposure for dry cleaning workers
- Measurable perc levels in indoor air for residents living in buildings above or adjacent to perc-using dry cleaners
- Groundwater contamination that persists for decades when perc enters soil through improper storage or disposal, spreading through aquifers far beyond the original contamination site
California has been systematically phasing out perc-based dry cleaning operations for years. San Francisco has been among the most aggressive jurisdictions in enforcing that transition. A dry cleaner in San Francisco that still uses perc is not simply behind the times. It is making an active choice to continue using a substance that poses documented risks to its workers, its neighbors, and the groundwater beneath the city, when alternatives that clean just as effectively are available.
What Eco-Friendly Dry Cleaning Actually Uses
The transition away from perc has produced several viable alternatives, each with a different environmental and performance profile.
Hydrocarbon solvents, derived from petroleum, are the most widely adopted perc replacement. They are gentler on fine and delicate fabrics than perc, produce softer hand feel in wool and cashmere, and break down in the environment more readily than chlorinated solvents. Their toxicological profile is significantly better than perc and they do not persist in groundwater in the same way.
Liquid carbon dioxide dry cleaning uses CO2 pressurized to a liquid state as the cleaning medium. The CO2 is recaptured industrial CO2, sourced from existing emissions rather than newly generated, and recovered and reused in a closed-loop system after each cleaning cycle. Liquid CO2 cleaning is exceptionally gentle on delicate fabrics and produces no solvent residue in the garment or the environment.
Silicone-based solvents, marketed under trade names including GreenEarth, use a silicone fluid that is chemically inert, non-toxic, and biodegradable. It breaks down in the environment into sand, water, and carbon dioxide, leaving no persistent chemical residue. Like liquid CO2, silicone-based cleaning is particularly well-suited to delicate fabrics and produces a soft, gentle result that perc-based cleaning cannot match for fine fibers like cashmere and silk.
At Laundre in San Francisco, eco-friendly solvents are the standard across all dry cleaning orders. This is not a premium add-on or a special service tier. It is the baseline process applied to every garment, at every price point, for every customer.
Closed-Loop Solvent Recovery and Waste Reduction
The solvent a dry cleaner uses is only part of the environmental equation. How that solvent is managed through the cleaning process and what happens to it afterward matters just as much.
Professional dry cleaning machines designed for eco-friendly operation use closed-loop solvent recovery systems. After each cleaning cycle, the solvent is extracted from the drum, filtered to remove dissolved soiling and particulates, and returned to the reservoir for reuse. The filtered residue, which concentrates the removed soiling from garments, is collected and disposed of as regulated waste rather than being allowed to enter drainage systems or evaporate into the air.
A dry cleaner operating a closed-loop system is reducing the volume of chemical input required for each cleaning cycle. That reduction has direct cost implications that make the investment in proper equipment economically rational as well as environmentally sound. It is not an environmental responsibility in the abstract. It is a structural operational choice with measurable consequences.
Packaging, Energy, and the Broader Operational Footprint
Environmental responsibility in dry cleaning extends beyond solvent choice. The packaging used to return garments, the energy consumption of cleaning and pressing equipment, and the logistics of pickup and delivery all contribute to the overall environmental footprint of a dry cleaning operation.
Conventional dry cleaners return garments in single-use plastic bags that go directly into landfill after a single use. The cumulative volume of single-use plastic generated by a busy dry cleaning operation across a year is substantial. A dry cleaner committed to sustainability looks for alternatives including reusable garment bags, recyclable packaging materials, or reduced packaging for garments that do not require individual covering. That choice reflects whether sustainability is a genuine operational value or simply a marketing position.
Energy consumption comes primarily from the cleaning machines, the pressing and finishing equipment, and climate control in the facility. Modern eco-friendly cleaning equipment is generally more energy-efficient than older perc-based machinery, in part because closed-loop solvent recovery systems require less heat input than open-cycle perc machines.
Why This Matters Specifically in San Francisco
San Francisco has a particular relationship with environmental accountability. The city has been at the forefront of sustainability policy for decades, from its aggressive recycling and composting programs to its early adoption of single-use plastic restrictions and its leadership on air quality regulation. Residents who recycle, compost, choose sustainable products, and support local businesses with strong environmental practices bring those same expectations to the services they use.
A dry cleaner operating in San Francisco that has not made the transition to eco-friendly solvents is out of step with the values of the community it serves. A dry cleaner that has made that transition is not doing something exceptional. It is meeting the standard that San Francisco residents reasonably expect from a local service provider. Laundre’s commitment to eco-friendly dry cleaning is the operational foundation of the business, built into the equipment, the solvent choices, the waste management practices, and the overall approach to running a dry cleaning facility in a city that takes environmental responsibility seriously.
Making an Informed Choice
The next time you bring a garment to a dry cleaner, the question worth asking is simple: what solvent do you use? A dry cleaner confident in its environmental practices will answer that question directly and without hesitation. One that deflects, gives a vague answer, or cannot explain the difference between its current solvent and perc is telling you something important about its operational priorities.
