As a raw material for production of biodiesel with our equipment EXON you can use waste deep-fat frying oils. Tha main required characteristic for this oil is to have acid number (up to 1,5%). Do you have some questions? Do not hesitate! Write to us right now! If the acid number of oil is higher than 7% you need to refine the oil before use it for the process. If characteristics of the raw material meet the requirements then at the end of the EXON working process you get biodiesel which meets european standard EN 14214.
