Clariant said it expects to complete the purchase of the assets of BASF'S U.S. attapulgite business--one of the largest miners and producers of the clay material, which Clariant said can help remove contaminants in renewable fuel production--in the summer of 2022.

"This acquisition fits very well with our growth strategy to grow through sustainability-focused innovations and bolt-on acquisitions," Clarient Chief Executive Conrad Keijzer said in a statement, adding it would improve its position in renewable fuels purifications.
