From vegetable oils to waste streams —
we process them all.
AT pioneers biodiesel production through its MULTI-FEEDSTOCK technology, enabling the efficient conversion of a wide spectrum of renewable oils and fats into high-quality biodiesel. Our process flexibility allows the use of both conventional and advanced feedstocks in line with RED III, including materials listed under Annex IX Part A and Part B.
