What should used oil be collected by?

1. Sold as fuel oil

2. Collected by a local environmental service

3. Pumped into the nearest sewer

4. Burned

The correct answer is: Collected by a local environmental service

Used oil should be collected by a local environmental service because this ensures that it is handled properly in accordance with environmental regulations and safety practices. Local environmental services are equipped to manage hazardous waste appropriately, preventing contamination of land and water resources. They typically have the necessary processes for recycling or disposing of used oil in a safe manner, which can prevent potential harm to the environment or public health. Using options like selling used oil as fuel could contribute to improper use if the oil does not meet quality standards. Pumping used oil into the nearest sewer poses a serious risk of environmental contamination and violates regulations. Burning used oil may release harmful substances into the air without proper equipment to manage emissions, leading to air pollution and health hazards. Therefore, the most responsible and regulatory-compliant option is to have used oil collected by a local environmental service.
