From Lubricants to Packaging Materials: ARS Scientists Just Say "No" to Petroleum
At the NCAUR lab in Peoria, chemist Sevim Erhan (now center director at the Eastern Regional Research Center in Wyndmoor, Pennsylvania) formulates a biodegradable lubricant using an ARS patented biobased antiwear additive. Few sounds are more nerve-wracking than the scraping of metal on metal

The push toward lifetime lubes
, distillation separates hydrocarbon molecules by boiling point and their respective molecular size and viscosity. Added solvents selectively extract aromatics and other impurities such as sulfur, nitrogen, and oxygen compounds. These extracts are an environmental concern and are often burned as fuel
