Reprocessing is often very rudimentary; techniques include filtration（过滤）, boiling, （精炼）and the removal of adulterants（掺杂物）. It is then packaged and resold as a cheaper alternative to normal cooking oil. Used kitchen oil can be purchased for between 859 and 937 dollars per ton while the cleaned and refined product can sell for 1,560 per ton. Thus there is great economic incentive to produce and sell illegal cooking oil. It is estimated that up to one in every ten lower market restaurant meals consumed in China is prepared with illegal cooking oil.
