Campuses Fight Microplastic Pollution

CLEANR has launched a new offering that will enable U.S. universities to reduce their microplastic emissions significantly. Under the program, CLEANR will deploy its breakthrough microplastics filter to on-campus washing machines to prevent microplastics from going down the drain and entering the environment.

CLEANR first debuted its filters at Case Western Reserve University (CWRU) as part of its sustainability efforts.

Ahlstrom Leading the Way in Lignin-Based Filtration Solutions

Ahlstrom, a global leader in fiber-based specialty materials, enhances its offering for its patented lignin-based filtration media. A proven, high-performance alternative to traditional filtration materials further supports customers in making sustainable choices.

“By focusing on washing machines, U.S. universities can join in stopping up to a third of microplastics from entering our waterways,” said Max Pennington, Co-Founder & CEO of CLEANR. “Our filtering technology makes the job almost as simple and easy as removing lint from a dryer for university communities and makes a measurable impact on microplastic emissions.”

According to the International Union for Conservation of Nature, washing machine wastewater is the world’s largest source of microplastic pollution. CLEANR’s filter – based on its core VORTX technology – was recently certified by the prestigious Shaw Institute to remove over 90% of microplastics as small as 50 microns. www.cleanr.life

Rensa Filtration, a leading manufacturer and distributor of consumable, mission-critical air filtration solutions, announced that its SuperFlo HEPA V-Bank and HEPA Deep Pleat filters have been evaluated by UL Solutions to meet the requirements of the UL 900 Standard for safety for Air Filter Units. The UL Mark underscores Rensa’s commitment to providing safe, high-quality filtration products and confirms that these filters have undergone rigorous third-party testing and verification by UL Solutions.

Brandon Ost, CEO and Founder of Rensa Filtration, said, “We’re excited that our

SuperFlo HEPA V-Bank and Deep Pleat filters now have UL 900 Classification. These filters are essential for critical industries like data centers, healthcare, and advanced manufacturing, where high-performance air filtration is critical. Our ongoing investment in our offering of HEPA filters helps us stay at the forefront of the air filtration industry.”

Rensa SuperFlo HEPA V-Bank and Deep Pleat filters are engineered to perform in adverse, critical, and sensitive conditions. These filters provide superior performance with high dust-loading capacity and low resistance to airflow, offering 99.97% and 99.99% efficiency at 0.3 microns. Constructed with a 40% lighter high-impact plastic frame and Rensa Filtration’s proven mini-pleat technology, they deliver superior filtration, resulting in enhanced performance, improved energy efficiency, and a lower total cost of ownership. www.rensafiltration.com

Ahlstrom ECO™, introduced in 2023, combines a proprietary lignin-based impregnation, replacing fossil-based resin with a renewable, bio-based cellulose filtration media. This innovation significantly reduces reliance on non-renewable resources while maintaining exceptional durability, mechanical strength, and filtration performance.

Designed for liquid and air filtration, Ahlstrom ECO™ is ideal for engine oil and engine air intake filtration, as well as for industrial filtration systems operating under challenging conditions. Delivering superior filtration performance helps optimize equipment protection while contributing to a lower environmental impact.

Ahlstrom estimates that the lignin-based impregnated filter media displays a lower carbon footprint than a standard fossil-based resin media. Additionally, the lignin-based impregnation significantly reduces 50–70% of formaldehyde emission during the curing process. This makes the filter media an industry-leading choice for manufacturers seeking to improve sustainability without compromising performance or reliability. A flame-retardant version is also available for air filtration applications requiring enhanced fire safety. www.ahlstrom.com
