Most families in Singapore improperly dispose of used cooking oil by dumping it down sinks or toilets, totaling thousands of kilograms daily. The document then discusses converting used cooking oil into biodiesel, an environmentally friendly fuel that reduces greenhouse gas emissions and pollution.

5. What are we going to study and research on? We are finding a simple way to convert used cooking oil into biodiesel which is environmentally friendly and easy.

11. How to judge the quality of biodiesel? Main factors : Density, Heating Capacity, Lubricating Property, PH Value, etc. Our experiment : testing on toy cars

12. Assume that a household(4 people) produces 2 Kg used cooking oil weekly. The amount of used cooking oil per year ≈ 100 Kg
