Biodiesel produced from waste vegetable oil

Description of the problem:

Vegetable oil is commonly used in households, restaurants, and hotels, but, when used for frying, it undergoes certain changes and chemical alterations that make it necessary to treat and dispose of it correctly.

Waste vegetable oil treated properly serves as the raw material necessary to produce mainly biodiesel, thus generating economic activity and reducing the use of fossil fuels.
Pouring waste vegetable oil down the sink or flushing it down the toilet contributes to the pollution of rivers and lakes: one liter of waste vegetable oil is 5,000 times more polluting than sewage. In addition, waste vegetable oil can pollute approximately 40,000 liters of water.

General purpose:

To tackle the disposal of cooking oil and the subsequent pollution wastewater causes to the environment by recycling it to produce biodiesel, soaps and other products in the chemical industry (waxes, varnishes, etc.)

Resolution strategy:

In order to achieve the purpose described above, it will be necessary to perform certain specific activities, which will essentially consist of:
• Receiving the raw material (WVO)
• Storing WVO in appropriate tanks
• Conducting the thermal treatment of waste vegetable oil in order to obtain biodiesel and other products, such as liquid soap, methylated oils, and repellent.
