UCSB Study: Low-Shed Detergent Slashes Textile Microfiber Emissions

In a groundbreaking study published in ‘Cleaner Materials’, a journal that translates to ‘Cleaner Materials’, researchers led by Dong Li from the Bren School of Environmental Science & Management at the University of California, Santa Barbara, have uncovered a significant breakthrough in reducing synthetic textile fiber fragments (sFFs) emissions during laundering. This discovery could reshape the textile industry’s approach to sustainability and have far-reaching implications for the energy sector, particularly in waste management and environmental impact mitigation.

The study, which involved four institutions, compared the effects of a conventional detergent with a novel “low shed” detergent on sFF emissions. The results were striking: the low shed detergent consistently reduced sFF emissions across different washing conditions and institutional methodologies. “The masses of sFFs per mass of textiles averaged, for each of the four institutions, 0.08 ± 0.06, 0.07 ± 0.07, 0.05 ± 0.04, and 0.08 ± 0.04 g/kg when using the novel detergent, versus 0.23 ± 0.13, 0.16 ± 0.11, 0.14 ± 0.05, and 0.11 ± 0.05 g/kg for the conventional detergent,” Li explained. This significant reduction highlights the potential of detergent formulation as a key factor in mitigating sFF emissions.

The implications for the energy sector are profound. As the world grapples with the environmental impact of microplastics, reducing sFF emissions from laundering could alleviate the burden on waste management systems and decrease the energy required for waste treatment. This could lead to more efficient and sustainable practices in the textile industry, aligning with broader environmental goals.

The study also explored the effects of the low shed detergent on whole garments comprised of mixed synthetic and cotton fibers. The results were equally compelling: the novel detergent resulted in significantly less FF (0.37 g/kg) than the conventional detergent (0.50 g/kg). Although the dryer emissions did not vary significantly by detergent type, the overall laundering process emitted relatively decreased FF masses with the low shed detergent.

Li’s research underscores the importance of intentional detergent formulation in reducing sFF emissions. This finding could pave the way for new detergents specifically designed to minimize fiber fragmentation, offering a practical solution to a pressing environmental issue. As the textile industry continues to evolve, the adoption of such detergents could become a standard practice, driving innovation and sustainability in the sector.

The study, published in ‘Cleaner Materials’, opens up exciting possibilities for future developments. As researchers and industry leaders delve deeper into the science of detergent formulation, we can expect to see more eco-friendly products that not only clean effectively but also protect the environment. This research is a testament to the power of interdisciplinary collaboration and the potential for scientific breakthroughs to shape a more sustainable future.
