Environment in Humanitarian Action Practice Test

The waste management hierarchy emphasizes preventing waste and extracting value at every opportunity, ending with a safe disposal as the last resort. The reasoning is that we should first reduce how much waste is produced, then reuse items, then recycle materials, and where possible recover energy from waste. Only when none of these options are feasible do we move to safe disposal, which means disposing of waste in a controlled, engineered manner to minimize environmental and health risks. In short, safe disposal is the final step because it is the last option after all reduction, reuse, recycling, and energy recovery possibilities have been pursued.
