GreenMantra Technologies, Sun Chemical Partner to Develop Polymers from Polystyrene Waste

GreenMantra Technologies, a clean technology company that produces polymer products from waste plastics, and Sun Chemical, a producer of printing inks, have agreed to partner to jointly develop polymers from recycled polystyrene waste for use in ink formulations.

The agreement combines Greenmantra’s new patent-pending process for converting waste polystyrene into useful polymers with Sun Chemical’s experience in inks formulation. The goal is to develop sustainable styrenic polymers as a replacement for fossil fuel-based materials in certain ink applications.

“Our team of scientists has had great success in the lab applying our technology and process to achieve depolarization of waste polystyrene, both rigid and foam, into styrenic polymers suitable for inks and other applications,” Domenic Di Mondo, GreenMantra’s senior director of research and business development, said in a statement. “We are looking forward to working with Sun Chemical’s experts to further refine these materials for commercial use.”

As part of the joint development project, GreenMantra will construct a pilot plant at its manufacturing complex in Brantford, Ontario, with an annual capacity of 1,000 metric tons. This will provide a supply of converted material for trialing in inks and other end-use applications and for initial commercial sales. Earlier this month, Sustainable Development Technology Canada (SDTC) announced it was providing $2.2 million in funding toward construction of the pilot plant.

 “This work is part of Sun Chemical’s ongoing efforts to develop new ink products that couple beneficial environmental profiles with improved performance,” said Russell Schwartz, chief technology officer, Sun Chemical, said in a statement. “We believe these new polymers may provide enhanced physical properties in select ink applications, while diverting polystyrene from the waste stream.”
