Cirql is touting its new midsoles as a sustainable material that can achieve significant reduction in carbon emissions.
In a new report, Cirql said its rTPU50 material delivers a “39 percent reduction in total carbon footprint versus the virgin TPU baseline,” the company said.
Cirql offers finished components and premium materials that are either industrially compostable or biodegradable or fully recyclable made in the Cirql factory. The brand’s mission is to keep shoes out of landfills. Materials such as its Cirql rTPU30, Cirql rTPU50, Cirql Zero and Cirql Zero36 give brands material options to enable them to meet their own climate goals.
Carbonfact, which focuses on product life cycle assessments, partnered with Cirql to assess actual factory performance data using a carbon-accounting platform in line with standards such as the Greenhouse Gas Protocol.
Instead of relying on proxies and generic datasets for life cycle assessments, amidst an increasingly complex global regulatory landscape, Cirql vice president and general manager Matt Thwaites said that working with Carbonfact “allows us to measure the footprint of Cirql’s materials solutions with a level of detail and rigor that matches our ambitions for impact and transparency.”
A top initiative at Cirql is to serve as a trust and transparent strategic partner for brands facing new and existing regulations across the globe. In partnering with Carbonfact, Cirql will generate third party-verified, granular environmental data for its circular materials. That will give its brand partners a clearer, science-base view of impact from raw materials through end-of-life. The midsole brand said it and Carbonfact “achieved unmatched accuracy for midsoles made with supercritical injection foaming.”
All life cycle assessments shared through Carbonfact’s supplier platform are verified by its in-house science team, ensuring that the data is credible and comparable for the brands that evaluate and adopt new materials such as those from Cirql.
Cirql is a subsidiary of insole maker OrthoLite. The two were acquired last year by Coats Group plc in a $770 million deal. The acquisition was completed in October 2025.
