Chemours Titanium Technologies, aside from colour and opacity, plastics industry customers are looking for efficiency in processing and energy management, including thermal management and light protection. She says the company has several grades of TiO2


that meet these demands in


different applications, including a grade for film and sheet that is certified by DIN Certco for use in compostable resins. Circularity is also a concern, Stancik says. “To

value chain in an initiative called Remove2Reclaim to develop an efficient, cost-effective, and sustain- able process for recovering TiO2


, other additives,


and polymers from plastic products at their end of life, such as post-consumer plastic waste. The goal is to create a completely new recycling strategy that could enable reclaimed TiO2


and polymers to


be returned to high-value applications, contribut- ing to the circular economy while yielding signifi- cant benefits to society and the planet.” Chemours also announced in August this year the commissioning of a new mineral sand mine in Florida that will expand its supply in the US of the minerals it uses to make its Ti-Pure brand of TiO2
