When poured down a gutter or a drain, oil can find its way to oceans, lakes, and rivers. It contains metal particles and other toxic substances, meaning it’s hazardous for plants and wildlife.
If motor oil is poured down a drain, it can contaminate 1 million gallons of fresh water, which is enough drinking water for 50 people for one year, according to the Environmental Protection Agency.
The recycled oil can power furnaces or be used to fuel power plants that supply electricity. The re-refined oil is even safe to place back into car engines.
Pennsylvania Department of Environmental Protection Agency encourages auto parts stores and service stations to collect their collection sites on a daily occurrence, as well as inspecting the disposition of the oil.
