Calculation and Evaluation of Carbon Dioxide Emissions from the Refining of Biodiesel Fuel with Waste Cooking Oil

The Production Rate in the Case Study is 100L/day

Abstract

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.
