Analysis on Influence of Utilization of Waste Cooking Oil as Bio Diesel Fuel in Regional Area :

A Case Study in Wakayama Prefecture

Abstract

In this paper, quantitative environmental effects of utilization of waste cooking oil as bio diesel fuel (BDF) were analyzed using waste input-output table of Wakayama prefecture. The result revealed that: i) prefecture-wide collection of waste cooking oil could reduce direct and indirect carbon dioxide of 1692ton-CO₂; ii) on the other hand, transportation-derived carbon dioxide emission greatly increases associated with expansion of the oil collection area; iii) carbon dioxide reduction cost could reduce by nearly 8% in the case of limited collection of household-derived oil by comparison of prefecture-wide oil collection.
