What might indicate the need for cell closure in landfill operations?

The need for cell closure in landfill operations is primarily indicated by regulatory mandates or environmental issues. Regulatory agencies enforce rules and standards that dictate when a landfill cell must be closed to protect public health and the environment. Various factors can trigger such mandates, including contamination concerns, violations of environmental laws, or exceeding permitted capacity. Environmental issues, such as groundwater contamination or air quality concerns, can necessitate closure to prevent further environmental degradation and ensure compliance with the law.

In contrast, while resource depletion and increased operational costs may impact the overall management of landfill operations, they are not direct triggers for closing a landfill cell. Public demand for higher recycling can influence waste management practices but does not typically lead to immediate cell closure.
