What type of fluid should be avoided in garbage disposal practices?

Oil should be avoided in garbage disposal practices because it can create significant environmental issues when it enters the wastewater system. Oil doesn't break down easily in water and can lead to clogs in pipes and blockages in treatment facilities. Additionally, it can contaminate water supplies, harm aquatic life, and contribute to pollution. Proper disposal methods for used oil, such as taking it to recycling centers or special collection events, are not only environmentally friendly but also often required by local regulations. By managing oil responsibly, individuals can help protect public health and the environment.
