The chemical name of "industrial mixed oil" is fatty acid triglyceride. It is refined from restaurant waste oil (commonly known as geo-oil) and brine oil as raw materials. It can be used as raw material for biodiesel, plasticizer, and oleic acid. Raw material oils such as oils and anti-caking (lubricating) agents are widely used in the production and processing industries and comply with the sustainability requirements of the EU Directive on the Promotion of the Use of Renewable Energy issued in 2009.
