Puralube Germany GmbH operates two refineries according to the innovative UOP HyLube process. Total throughput is 150,000 metric tons per year with used oil as feedstock. The plants are located in the Zeitz industrial park, approximately 40 km south of Leipzig, Germany. Since beginning production at the world's first refinery of this type in mid-2004, the Zeitz site has been producing high-quality API Group II and III base oils. In late 2008, a second plant was brought on line at the same location. Each year, the two plants consume approximately 150,000 metric tons of feedstock. They produce about 90,000 metric tons of base oils and another 50,000 metric tons of other mineral oil products. Currently approximately 110 employees work in production, quality assurance, sales, and administration at this location.
