The collaboration will combine CleanKore’s patented low-impact dyeing technology with HMS’ sludge-free washing and finishing process.

The two clean-tech innovators plan to pilot a joint programme with the goal of introducing a “fully integrated, planet-positive solution” across global markets.

CleanKore’s dyeing process is claimed to remove the need for Potassium Permanganate (PP) and cuts down on water, chemical, and energy consumption across the supply chain. This method also manages dye penetration and maintains fabric performance.

HMS CEO and founder Beyza Baykan said: “This collaboration brings two innovation engines together. CleanKore is transforming the beginning of the denim journey, and HMS is transforming the end. By combining our technologies and vision, we will be able to offer the denim world a comprehensive concept to significantly reduce their environmental footprint while saving on time & cost.”

HMS contributes a composite washing stones designed to replace both pumice stones and conventional washing chemicals, thereby eliminating sludge production, reducing water use, and supporting consistent results in finished textiles.

The combined technologies will enable mills and laundries to reduce environmental impact from the dyeing stage through to garment washing.

The companies have outlined that this partnership forms the initial phase of a larger collaboration, with plans for further initiatives, pilot outcomes, and commercial launches to be shared in the coming months.

CleanKore CEO Darryl Costin Jr. said: “We are honoured to partner with an innovative and like-minded company in HMS that shares our passion in providing transformational, eco-advanced solutions to the global denim community. HMS’ breakthrough stone alternative to pumice is the perfect counterpart to CleanKore and we look forward to a bright future together.”
