This document discusses converting used cooking oil into biodiesel. It describes how most families improperly dispose of used cooking oil by dumping it down sinks or toilets. It then outlines a simple process to convert the used oil into biodiesel through a chemical reaction involving methanol and potassium hydroxide. The procedures involve heating the oil, adding the chemicals, and separating the biodiesel layer from the glycerin layer. The resulting biodiesel is then washed and dried. The document suggests testing the biodiesel on toy cars to evaluate its quality. Producing biodiesel from waste oil has environmental benefits over disposal since biodiesel burns cleaner and produces fewer emissions.

1. How Do You Deal With Your Used Cooking Oil? Most of the families dump cooking oil, poultry fat and grease into the kitchen sinks or the toilet bowls directly. It is reported that each day, thousands of kilograms of oil is directly disposed in Singapore.

2. How About Converting It Into Something USEFUL And NOT HARMFUL To The Environment

4. Positive Environmental Effects of Biodiesel Biodiesel fuel reduces carbon dioxide emissions by up to 80%. Biodiesel reduces the formation of acid rain because it produces no sulfur dioxide, which is the key element in creating acid rain. Biodiesel burns much cleaner, so the black smelly smoke one usually sees puffing from vehicles which use diesel engines can be eliminated. Biodiesel fuel takes considerably less time to degrade in the event of a spill, usually about twenty eight days, which is about four times faster than gasoline or regular diesel fuel.

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 by adding chemicals.

7. Potassium hydroxide

9. Hotplate stirrer (Denvile)

11. Measuring cylinder

12. Electronic scale

13. Glass stirrer

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