GFBiochemicals, an Italian start-up producing the biobased intermediate levulinic acid, has acquired Segetis, a U.S. firm that makes levulinic acid derivatives. The purchase, for an undisclosed sum, provides GF with access to the fledgling levulinic acid market in the U.S. plus Segetis’s portfolio of more than 250 patents. Segetis operates a plant in Minnesota. GF opened a plant in Italy last year.
