Microfibers Capture: How to Reduce Laundry Pollution

Microfiber pollution is an environmental challenge that begins with everyday textile care. During washing, friction and mechanical action release small fibers from garments, towels, sheets, and other textiles. These particles are carried away in wastewater, where conventional treatment processes may not capture all of them.

Synthetic microfibers contribute to microplastic pollution, while fibers from natural textiles can also carry dyes, finishes, or chemical residues.

Once released into hydric environments, these particles may be ingested by organisms and potentially enter the food chain. Reducing their discharge at the source helps limit the amount of textile-derived material entering the environment and its potential exposure to people and wildlife.

For professional laundries processing large volumes of textiles every day, microplastics filtration provides a practical opportunity to reduce pollution before it leaves the facility. Rather than relying exclusively on downstream wastewater treatment, laundries can take action directly within their own operations.

Girbau Zero Microfibers is a centralized rotary filtration solution designed to capture microfibers, including microplastics, directly from washing wastewater. It is part of Girbau’s Zero Platform, a range of sustainable laundry solutions designed to address water consumption, energy efficiency, microfiber pollution, and packaging waste.

The system uses a rotating cylindrical mesh and tangential filtration to separate fibers from the water. Its filtration process combines rotation, continuous water flow, and fiber aggregation to capture particles while maintaining stable filtration performance.

The captured fibers are collected in a dedicated drawer as nearly solid waste, making them easier to remove and dispose of without creating an additional liquid waste stream.

The system uses a 50-micron mesh. Laboratory tests reported filtration efficiencies of 83–96% under the tested conditions, including the capture of some particles smaller than the nominal mesh size. Actual performance may vary depending on wastewater characteristics and operating conditions.

By capturing synthetic and organic fibers before wastewater is discharged, Zero Microfibers helps laundries reduce their contribution to microfiber pollution. This is particularly relevant for businesses looking to move beyond broad sustainability commitments and demonstrate concrete improvements in their environmental performance.

Environmental requirements are evolving, and microplastic pollution is receiving increasing attention from policymakers, customers, and the wider textile industry. For laundry operators, waiting until new requirements become mandatory can create additional pressure to adapt equipment, processes, and investment plans.

Introducing microplastics filtration proactively allows laundries to prepare for potential future requirements while gaining practical experience with the technology. It can also help organizations respond to customer requests for more environmentally responsible textile care services.

Although installing a filtration system does not automatically guarantee compliance with future regulations, it provides a foundation for adapting to changing expectations and demonstrating a proactive approach to environmental management. Definetly, it keeps laundries ahead of upcoming regulation. For laundries, greater resilience means being better prepared for what comes next—not simply reacting when requirements change.

Customers increasingly expect sustainability claims to be supported by concrete actions. For commercial laundries serving hospitality, healthcare, and industrial customers, environmental performance can become an important part of the value they offer.

Microfibers filtration creates an opportunity to demonstrate that sustainability is being addressed within the laundry process itself. By capturing microplastics and other textile fibers before they enter wastewater, laundries can show how they are working to reduce a specific environmental impact associated with textile care.

This can strengthen relationships with customers that have their own sustainability objectives and are looking for service providers capable of supporting them. It also provides a tangible example of how investment in technology can contribute to more responsible operations.

Rather than treating sustainability exclusively as a communications message, laundries can make it part of their everyday production processes. At Girbau, this approach is reflected in our commitment to sustainability , which connects environmental responsibility with innovation and operational performance.

One of the main challenges of introducing environmental technologies is ensuring they fit into existing operations without requiring major changes to equipment or production workflows. ZM is designed to address this challenge through a compact, centralized configuration that can be integrated into different laundry environments.

Unlike solutions installed individually on washing machines, its centralized design allows wastewater from multiple machines to be directed to a single filtration unit. This makes the system suitable for different washing processes and equipment configurations, including existing laundries looking to introduce microfiber filtration without replacing their washing machines.

Its modular design also allows the solution to be adapted to different production requirements. Depending on the facility layout, wastewater can be collected through a common drain pit, a shared collector, or a direct-feed configuration. An optional buffer tank helps regulate incoming wastewater flow where required.

The system supports a maximum water flow of up to 5,760 liters per hour, with the appropriate installation configuration determined by each laundry’s wastewater volumes and hydraulic requirements. For operators, this flexibility reduces the barriers to introducing microplastics filtration and allows the technology to be incorporated into existing infrastructure.

Environmental improvements must also be practical for the people responsible for running the laundry. Zero Microfibers combines automatic operation with a self-cleaning filtration system designed to minimize manual intervention.

Integrated nozzles periodically clean the rotating mesh using filtered water, helping maintain consistent filtration performance without chemical cleaning. A visual LED indicator shows the system’s operating status and alerts employees when the solid waste collection drawer needs to be emptied. The collected fibers can then be removed from the drawer for appropriate disposal, simplifying waste handling and routine maintenance.

Together, these features help laundries introduce microfiber filtration without adding unnecessary complexity to their daily operations.

A more sustainable laundry is not defined by a single technology. It is built by continuously improving how water, energy, equipment, and operational processes work together. Microplastics filtration addresses an environmental impact that can be overlooked when sustainability efforts focus exclusively on resource consumption.

By integrating Zero Microfibers into their existing operations, laundries can reduce microfiber discharge, prepare for evolving environmental expectations, and demonstrate meaningful progress toward more responsible textile care.

Its compact, centralized, and retrofit-ready design makes this possible without requiring laundries to replace their existing washing equipment.
