Which waste is suitable for disposal in a class 3 landfill?

Choosing farm and landscaping waste as suitable for disposal in a class 3 landfill aligns with the classification system used for landfills based on the types of waste they can accept. Class 3 landfills are typically designed to handle non-hazardous, solid waste.

Farm and landscaping waste generally consists of materials like grass clippings, branches, leaves, and other organic matter that can decompose over time. This type of waste does not contain harmful substances or pollutants that could leach into the environment.

Household waste may also be non-hazardous but can include a mix of organic and inorganic materials, some of which may not be permissible in a class 3 landfill, depending on local regulations. Hazardous waste is specifically prohibited from class 3 landfills due to its potential to harm human health and the environment, necessitating specialized handling and disposal methods. Construction waste may contain materials that are not allowed in class 3 landfills, such as certain types of concrete, metals, or large amounts of non-decomposable waste.

Thus, farm and landscaping waste is the correct choice as it fits the criteria of what class 3 landfills are intended to accept: organic, non-hazardous waste that can be managed responsibly.
