This paper describes how to produce a biodiesel from the oil in the waste soup of ramen noodles, and especially clarifies an amount of oil in waste soup, the energy profit ratio (EPR) of the production of biodiesel from the oil in waste soup of ramen noodles and the engine performance of the biodiesel from waste soup of ramen noodles. As a result, from the waste pig bone (ton-kotsu) soup the recovered tri-glyceride was about 11g per a soup. The biodiesel produced from the oil in the waste soup of ramen noodles by using ordinary alkyl catalyst method has low cold flow properties, due to the high content of the saturated fatty acid methyl ester such as C16:0, C18:0 and so on. And it is estimated that the amount of BDF from a ramen noodle restaurant is about 2.4L if the customers are around 300 per day, and this means that the 9.9 kW co-generation system is able to be operated for an hour per day. About energy profit ratio analysis, if the oil separation process is improved, EPR from the waste soup to biodiesel will become higher than 5.0. Furthermore, engine test is performed by using BDF from the waste soup of ramen noodles as B5. As a result, it is shown that fuel consumption rate and emissions are almost the same as the case of using gasoil.
