Hi, I am Chonghwa Jon, CEO of Bizel Corporation, a licensed biodiesel producer in Korea. I wonder what the specification of used cooking oil & available quantity per month by ton, payment terms (We prefer L/C basis) are. We are in particular keen on spec including free acid value, melting point (below 0 degee C, moisture content, iodine value. It will be even better if it is refined used cooking oil. Can you kindly provide?
