extraction. Sulzer Chemtech’s technology will allow us to produce high-quality circular aromatics from cata- lytically converted oil products derived from plastic waste. This collaboration will drive up sustainable prac- tices in industry.” Sander van Donk, Head Global Technology Business at Sulzer Chemtech, concludes: “We are pleased to sup- port Encina’s mission of enabling circularity in plas- tics recycling by providing our SuRe BTX technology downstream of its catalytic conversion process. This novel value chain builds on Sulzer Chemtech’s com- mitment to circularity and opens up an entirely new market for ultra-pure circular benzene and toluene pro- duced from waste plastics.”
787/tr-oz in May 2021 and, for a short period in March 2022, even exceeded $3300/tr-oz. Over the same period, market pricing of platinum has increased by 41%, from $756/tr-oz in April 2020 to an average March 2022 value of $1069/tr-oz. In response, W. R. Grace & Co. developed optimised versions of both its palladium and platinum based CO promoters. These optimised CO promoters incorpo- rate advances in alumina technology that allow CO promotion activity to be maintained at lower metals levels, resulting in more cost-effective products for our customers. The process Grace uses to incorporate palladium and platinum onto the combustion pro- moter naturally leads to a particle where the majority of the metals are located at the surface. However, the

As recent inflation hit many Western economies, prices for key raw materials such as palladium became more volatile. The average monthly palladium price increased by 30% from $2097/tr-oz in April 2020 to an average March 2022 value of $2656/tr-oz.* The aver- age monthly price peaked at $28
