Description

Recently, some local governments have refined biodiesel fuel from waste cooking oil for waste volume reduction and recycling. In this study, the recycling system which refining of biodiesel calculated CO2 emissions based on data measured by LCA method. We compared CO2 emissions when cooking oil was recycled into BDF and when it went through sewage treatment or was incinerated. The calculated CO2 emission factor was 1.34～1.65kgCO2 /L when cooking oil was recycled. The CO2 emission by refining cooking oil was 41~52% less than that obtained by disel oil. The reduction for a year per capita was calculated as 265gCO2 /year.
