What is Waste Oil
Waste oil is any petroleum-based or synthetic oil that has been rendered unusable for its original purpose due to contamination or degradation. Common sources of liquid waste include oils from vehicles, industrial machinery, and commercial kitchens. As these oils are used, they accumulate impurities such as dirt, metal shavings, water, or chemicals, which degrade their performance and can cause significant harm if not managed properly.
Waste Engine Oil
This type of oil comes from:
- Used motor oil from cars, trucks, and motorcycles.
- Hydraulic fluids from heavy machines.
- Transmission fluids from vehicles.
- Industrial oils used in manufacturing equipment.
These oils collect contaminants such as metal shavings, dirt, and chemical residues, which degrade their quality and can damage engines and machinery if reused without treatment.
Waste Cooking Oil
Cooking oil becomes waste after being used in food preparation. Sources include:
- Vegetable oils like canola, sunflower, and olive oil.
- Animal fats such as lard and tallow.
- Grease collected from commercial kitchens.
High cooking temperatures and food particles degrade these oils, making them unsuitable for further cooking.
