Applications for biodiesel
- Urban vehicles：garbage trucks, buses, ships, and shipping on surface.
Biodiesel is better replacement fuel for diesel
- It is compared with CNG (condensed natural gas) and methanol.
- It is conclusion from fuel cost, vehicle cost, cost of basic facility, safety, reliability, and fuel accessibility.
Emission reduction estimation
- It is applied TEDS5.0, the database of air pollutant emission in Taiwan from EPA to calculate the average emission parameters of pollutant in Kaohsiung followed by the overall amount estimation.
- Biodiesel is replaced and used by all garbage trucks and buses.
Emission reduction estimation
Economy analysis
environmental benefits
pollutant reduction（MT/yr）* environmental cost（NT$/MT）
Environmental benefits of all types of biodiesel：
- Environmental benefits of BD9505 = NT$9,075,241/yr
- Environmental benefits of BD8020 = NT$8,005,721/yr
- Environmental benefits of BD5050 = NT$8,211,997/y
- Environmental benefits of B100 = NT$9,838,942/yr

conclusive estimation of economy
- The pollutant emission reduction of 94MT/yr of using BD9505 is the most significant. The biodiesel price of NT$20/liter of BD9505 is the lowest.
- The fuel consumption of BD9505 is the closest to that of premium diesel.
- From the aspects of economy, chemical property of fuel, fuel consumption, engine function, and pollution reduction performance, BD9505 is better than the other fuel and the feasibility is highest.
