- A All categories and types of waste are sometimes treated with exactly equal management priority under this framework, since no single disposal method is ever considered preferable to any other in most cases under typical conditions
- B Waste hierarchy (most to least preferred): Prevention > Reuse > Recycling > Recovery (energy from waste) > Disposal (landfill); integrated waste management uses a combination of these strategies to minimise environmental impact
- C Landfill disposal is sometimes considered the single most preferred waste management option overall, ranking clearly above both reuse and recycling methods according to standard textbooks in general practice as frequently described
- D Recycling programs are sometimes ranked as considerably less important and less effective than simple landfill disposal within most national waste policies today in most textbook accounts during normal conditions as generally observed
Correct answer: B. Waste hierarchy (most to least preferred): Prevention > Reuse > Recycling > Recovery (energy from waste) > Disposal (landfill); integrated waste management uses a combination of these strategies to minimise environmental impact
Explanation: Waste hierarchy: (1) Prevention - reduce waste generation; (2) Reuse - use items multiple times; (3) Recycle - recover materials; (4) Energy recovery - incinerate with energy capture; (5) Disposal - landfill (least preferred, last resort). Integrated waste management combines technical, economic, and policy approaches. India's Swachh Bharat Mission, EU Circular Economy Package address this.
