suggestion No.1
- Biodiesel can certainly improve the emission pollution for diesel vehicles in urban so it is suitable for use. Particularly the sulfur content and aromatic hydrocarbon content is considerably low thus significant improvements on SOx and PAH in urban is also made.
- Further tests on vehicles driving less distance and better conditions can be studied for driving on roads to confirm the pollution reduction effects of the types of biodiesel in the study.
suggestion No.2
- The price of biodiesel is still more expensive than that of premium diesel. However, if there is 25% diesel to be replaced by biodiesel, there is market competiveness for BD9505.
- Biodiesel is the trend for environmental development in the future. All countries are making efforts on research and development. For the environmental protection, it should be encouraged that the vehicles in urban of other cities and counties to use biodiesel.
- It is observed that leakage in garbage trucks. It is thus recommended that the oil fuel dilution can be analyzed for leakage evaluation on all of the old garbage trucks. In addition, proper major maintenance should be made to lessen the emission pollution and protect the vehicles.
