Sanitary landfills are designed to accept only non-hazardous solid waste, such as household waste, commercial waste, and non-hazardous industrial waste.

The primary purpose of a leachate collection system in a landfill is to collect and remove leachate, which is a liquid that contains dissolved contaminants from the landfill, to prevent it from contaminating groundwater.

Construction and demolition landfills are designed to accept only construction and demolition debris, such as wood, concrete, drywall, and asphalt.

The primary purpose of a gas collection system in a landfill is to collect and remove methane gas, which is a greenhouse gas produced by the decomposition of organic waste in the landfill.

Hazardous waste landfills are designed to accept only hazardous waste, which is waste that poses a threat to human health or the environment due to its toxicity, corrosivity, ignitability, or reactivity.

The primary purpose of a daily cover in a landfill is to prevent the formation of vectors, such as flies and rodents, which can spread disease.

Industrial landfills are designed to accept only industrial waste, which is waste generated by industrial processes, such as manufacturing, mining, and chemical processing.

The primary purpose of a final cover in a landfill is to prevent the formation of leachate, which is a liquid that contains dissolved contaminants from the landfill, to prevent it from contaminating groundwater.

Asphalt liners are not commonly used as landfill liners due to their limited effectiveness in preventing the migration of leachate.

The primary purpose of a leachate treatment system in a landfill is to remove solids, organic matter, and heavy metals from leachate to make it safe for discharge or reuse.

Passive gas collection systems are not commonly used in landfills due to their limited effectiveness in collecting methane gas.

The primary purpose of a landfill gas utilization system is to generate electricity, heat, and fuel from methane gas collected from the landfill.

Leachate collection is not a common type of landfill closure method, but rather an ongoing process that continues after closure to prevent leachate from contaminating groundwater.

The primary purpose of a post-closure care plan for a landfill is to monitor the landfill for leaks, maintain the landfill cover, and prevent the formation of vectors.

Landfarming is not a common type of landfill remediation method, but rather a method used to treat contaminated soil.
