Proper refrigerant disposal is essential in preventing ozone layer depletion. Many refrigerants, particularly older ones like chlorofluorocarbons (CFCs), contain chemicals that can break down ozone molecules in the stratosphere when released into the atmosphere. The depletion of the ozone layer increases the amount of harmful ultraviolet (UV) radiation that reaches the Earth, which can lead to health and environmental issues, including skin cancer and damage to ecosystems.

Disposing of refrigerants correctly involves recovering and recycling them rather than releasing them into the atmosphere. This practice aligns with regulations established by entities like the Environmental Protection Agency (EPA), which aim to protect the environment and public health. By ensuring that refrigerants are handled responsibly, the risk of contributing to ozone depletion is minimized, thereby contributing to the preservation of the stratospheric ozone layer.
