Himalaya Foods Ltd's sustainability committee wants to rank its waste handling options by environmental preference under the waste hierarchy. Which ordering runs from most preferred to least preferred?

The waste hierarchy ranks options from most to least preferred as prevention, reuse, recycling, recovery and finally disposal. Avoiding waste in the first place has the lowest environmental impact, while landfill disposal sits at the bottom. Other sequences either reverse or scramble this order.

  1. ADisposal in landfill, recovery, recycling, reuse, prevention
  2. BRecycling, prevention, landfill, reuse, recovery
  3. CPrevention, reuse, recycling, recovery, disposalCorrect
  4. DReuse, disposal, prevention, recovery, recycling

Explanation

The standard waste hierarchy places prevention or reduction at the top, followed by reuse, recycling, other recovery such as energy recovery, and finally disposal. The first option reverses this order; the other two jumble it.
