Sustainability in professional laundries has traditionally been measured in liters and kilowatt-hours. But a new indicator is quickly gaining relevance: what leaves the process through the wastewater stream. Among the issues drawing increasing attention, microplastics stand out as a specifically defined environmental topic with growing regulatory, operational, and reputational implications. For commercial and industrial laundries, the conversation is evolving. As awareness increases around the impact of textile washing on water systems and ecosystems, microplastics are becoming a critical part of the sustainability agenda—alongside water and energy efficiency.
What are microplastics and why do laundries matter?
Microplastics are tiny plastic particles, typically smaller than 5 millimeters, released from synthetic materials. In the context of laundries, they mainly originate from synthetic textiles such as polyester, which shed microfibers during washing.
These particles enter wastewater streams and, if not properly treated, can end up in rivers, oceans, and ultimately in the food chain. Microplastics are now present in water, soil, and even human bodies, raising concerns about long-term environmental and health impacts.
From emerging pollutant to defined risk
Microplastics were once considered part of a broader category of “emerging contaminants,” alongside substances such as pharmaceuticals or cosmetic residues transferred from textiles during washing.
Today, that has changed.
Microplastics are now clearly identified, measured, and increasingly regulated, reflecting a growing understanding of their environmental impact.
Regulatory pressure is increasing
Regulation around microplastics is evolving rapidly, especially in Europe. The European Union is already taking steps to restrict intentionally added microplastics in products, improve wastewater treatment requirements, and promote filtration solutions in washing equipment.
Although these substances originate upstream in textile production, laundries may still be part of the value chain where these compounds are released.
For laundry operators, this means one thing: environmental compliance is becoming more complex and more demanding.
A business issue, not just an environmental one
Addressing microplastics is not only about sustainability, but also a business consideration. Clients—especially in sectors like hospitality and healthcare—are paying more attention to environmental practices across their supply chains. Sustainability requirements are increasingly part of procurement criteria, and laundries are expected to demonstrate responsible operations.
Laundries that are not prepared may face higher costs, compliance challenges, or competitive disadvantages.
The role of filtration and water treatment
One of the most direct ways to address microplastics in laundries is through filtration technologies.
A solution is to add microparticle filters designed to capture microfibers before wastewater is discharged. These systems allow laundries to retain a significant portion of microplastics generated during washing, preventing them from entering the environment.
This approach should also include water reuse systems, wastewater treatment solutions, and filtration of emerging contaminants. By combining these elements, laundries can reduce both water consumption and pollutant discharge.
From an operational perspective, this represents a shift from simply using water to actively managing water quality and environmental impact.
Towards a more controlled and sustainable process
The challenge of microplastics reflects a broader transformation in the laundry industry. Operations are no longer evaluated only by efficiency or output, but also by their environmental footprint.
The goal is not just to reduce consumption, but to control the entire process, including what is discharged into the environment. Microplastics are part of that equation.
Ultimately, addressing microplastics is about staying ahead of change. As regulation evolves and customers demand greater transparency across the supply chain, laundries that begin assessing their wastewater streams, exploring filtration options, and strengthening water treatment strategies will be better prepared to protect both the environment and their business—while reinforcing trust with the industries they serve.
