Has this fat been rendered?


Find out what temperature it turns sold at and keep it 10 to 20 degF hotter.

The grease should be without water in it. I do not know what equipment you have. You can try a one stage reaction. If it has very little water in it it should work. Maybe try reacting 500 millilitres of grease with 110 millilitres methanol plus sodium hydroxide or potassium hydroxide at about 55 degrees centigrade for an hour or more with enough mixing during the hour. That might produce a well reacted crude biodiesel for you. Thanks
