Integrated waste management components include landfilling, composting, and waste combustion; which of the following is NOT considered a component?

• A. Process modification
• B. Landfilling
• C. Composting
• D. Waste combustion

Answer: (A)

The main idea is to distinguish between concrete waste-handling options and a preventive change in production. Integrated waste management groups practical options for dealing with waste into categories like disposal, biological treatment, and energy recovery. Landfilling fits as disposal, composting as biological treatment, and waste combustion as energy recovery. Process modification, however, is a preventive approach aimed at reducing waste at the source by changing how products are made or used, not a specific waste-handling option after waste is generated. That’s why it isn’t considered a component of the integrated waste management set described here.
