Dry cleaning, a common practice for maintaining delicate fabrics, has raised environmental concerns. It is less eco-friendly than people may think. The chemicals used in the process are toxic and can cause harm to the environment if not disposed of properly. 

Most laundry services use chemicals that threaten air quality, water, and soil.

It relies heavily on chemicals, notably perchloroethylene (PERC), a solvent that efficiently removes stains. The use of PERCs raises significant environmental and health concerns. For instance, according to the US Environmental Protection Agency (EPA), approximately 36,000 (70%) professional garment care facilities in the United States use PERC as their primary cleaning solvent.

The adoption of eco-friendly practices in dry cleaning can be a game-changer, significantly mitigating its environmental impact and offering a glimmer of hope for a more sustainable future.

The UK dry cleaning industry, worth a staggering £1.4 billion as of 2023, underscores its economic significance. However, with the industry projected to reach a value of approximately £57.8 billion by 2027, the need for a swift shift towards more sustainable practices is becoming increasingly urgent for the sake of our environment and economy. 

This article delves into the environmental footprint of dry cleaning, supported by statistics, trends, and expert insights. By providing a well-rounded discussion on the environmental implications regarding garment care, the article will explore innovative and eco-friendly alternatives emerging in response to environmental concerns.

What Do We Mean By Dry Cleaning Exactly

Dry cleaning is a cleaning process for clothing and textiles using a chemical solvent rather than water. Despite its name, dry cleaning is not actually "dry"; the clothes get wet but with a solvent that performs the cleaning action. The solvent used is typically tetrachloroethylene (perchloroethylene), which the industry calls "PERC".

This method cleans delicate fabrics that cannot withstand the rough and tumble of a washing machine and dryer. It helps prevent damage like stretching or shrinking and is ideal for delicate fabrics such as silk, wool, and velvet.

Moreover, it also eliminates the need for more time-consuming hand washing. Most dry cleaners also offer services like laundry for items like shirts and household textiles such as drapes and area rugs. 

A dry cleaner can reduce perchloroethylene use by 70% by converting from transfer equipment to a closed-loop dry-to-dry system.

Historically, solvents like gasoline and kerosene were used, but more sustainable options have been developed due to safety and environmental concerns. These include silicone-based solvents, liquid carbon dioxide, and hydrocarbon solvents, which aim to reduce the environmental impact of traditional dry cleaning practices.

However, the improper disposal of PERC and other chemicals has resulted in widespread environmental contamination at many dry cleaning sites.

The Environmental Impact of Dry Cleaning

The traditional dry cleaning solvent, perc, is a volatile organic compound (VOC) that can contribute to air pollution and has been associated with various health risks, including cancer and neurological effects. 

Notably, it uses chemicals like perchloroethylene (PERC), a solvent linked to various environmental and health issues. Annually, the industry emits substantial amounts of PERC into the atmosphere, contributing to pollution and health risks.

The industry also generates hazardous waste, including contaminated water and sludge, requiring careful disposal to prevent further environmental damage. This is characterised by its steady demand, attributed to the essential nature of the services it provides, which remain in constant need regardless of economic conditions.

What is so bad about Dry Cleaning for the environment?

Dry cleaning involves chemicals that are dangerous not only to the environment but also to human health. The primary solvent used, PERC, is a toxic chemical with extensive, harmful impacts:

  • Air and Water Pollution: PERC releases volatile organic compounds (VOCs) into the atmosphere, contributing to smog and air pollution. It also contaminates groundwater and soil, posing risks to wildlife and human populations.
  • Non-Biodegradable Waste: The waste products from dry cleaning, including used solvents and contaminated packaging, are challenging to dispose of and often non-biodegradable, leading to long-term environmental damage.
  • Energy Consumption: Dry cleaning facilities are energy-intensive, contributing significantly to carbon emissions and climate change

What is the impact of Cleaning?

The environmental impact of dry cleaning is multifaceted, affecting air, water, and soil quality. Annually, the industry contributes to significant pollution levels, with perc being a primary culprit.

To provide a clearer picture of the environmental toll of dry cleaning, we analyse its impact from various perspectives:

Total Impact per Year

Globally, dry cleaning releases over 160,000 tonnes of PERC annually. Each year, the UK releases thousands of tonnes of VOCs into the air, consumes millions of kWh of energy, and generates hazardous waste affecting land and water systems. In addition, one ounce of PERC can contaminate 2.5 million gallons of water above regulatory limits and over 650 gallons of hazardous waste per year on average. This contributes significantly to air and water pollution.

Impact per Day

Daily operations across the UK can emit hundreds of kilograms of harmful chemicals and use substantial energy. These activities emit about 438 tonnes of PERC into the environment, accumulating harmful effects over time.

Impact per Usage

Each dry cleaning cycle, on average, releases 15 grams of PERC per garment. Frequent use increases the personal and environmental health risks significantly.

The industry must move towards greener alternatives, such as professional wet cleaning, to mitigate these effects. Switching to greener alternatives like wet cleaning and liquid CO2 is crucial to reducing this £1.5 billion UK industry's massive ecological footprint. Regulatory action and public awareness are needed to drive this transition for a sustainable future.

Environmental Impact Compared to Everyday Things

Globally, the textile care industry contributes millions of tonnes of CO2 annually. In the UK alone, water-related CO2 emissions from laundry activities account for 6% of the total. When you consider the global scale, the impact is staggering. For instance, dry cleaning a suit emits more CO2 than driving a car for approximately 15 kilometres.

To put it into perspective, let's compare the CO2 emissions from dry cleaning and laundry services to everyday activities like driving a car, using a smartphone, and even eating a hamburger.

ActivityCO2 Emissions (kg CO2e)
Dry Cleaning (per garment)5.3kg CO2e
Laundry (per load)3.3kg CO2e
Driving a Car (per km)0.27kg CO2e
Using a Smartphone (per year)1.25kg CO2e
Eating a Hamburger2.5kg CO2e
One hour of television watching0.034 kg CO2e

These figures reveal that dry cleaning a single garment emits more CO2 than driving a car for 26.5 km. Similarly, doing a load of laundry is equivalent to consuming over a hamburger and a half in terms of CO2 emissions.

The comparison of CO2 emissions of laundry services to everyday activities highlights the importance of choosing eco-friendly options.
