Liquid Ion Solutions LLC (DBA RoCo)

RoCo, officially known as Liquid Ion Solutions, LLC, is an advanced materials company based in Pittsburgh, Pennsylvania, that specializes in the design, synthesis, and application of ionic liquids. Founded in 2014, the company utilizes these versatile compounds—often described as tunable liquid salts—as environmentally friendly alternatives to hazardous solvents for diverse industrial uses, including energy storage, polymer processing, and functional materials. Their technical capabilities are supported by in-house synthesis, rigorous testing, and a distribution partnership with IoLiTec, enabling them to provide both custom-engineered solutions and a commercial portfolio of ionic liquid products. The firm’s research and development efforts are frequently conducted in collaboration with academic institutions and supported by public funding from agencies such as the U.S. Department of Energy, NASA, and the USAF.

RoCo applies its chemical expertise to address complex global environmental challenges, specifically focusing on the circular economy and sustainable manufacturing. Key innovations include the development of ionic compatibilizers that facilitate the upcycling of plastics, such as polypropylene, by overcoming traditional mechanical property limitations. Furthermore, the company is engaged in CarbonTech initiatives, including the development of water-lean solvents for carbon capture and utilization, as well as research into recyclable, high-barrier packaging films and polyurethane waste reclamation. By providing consulting, feasibility studies, and cutting-edge materials technologies, RoCo helps corporate partners and industrial clients integrate sustainable, performance-driven solutions into their operations across sectors like packaging, clean energy, and waste management.
