Question

in terms of waste management, which of the following management options are the most useful/desirable?
reuse (reusing chemicals for other experiments)
prevention (reducing the amount of waste generated, ideally to zero)
recycling (recycling chemicals for other experiments)
disposal

Explanation:

In waste management, the waste hierarchy (or similar frameworks) prioritizes options based on environmental and resource efficiency. Prevention (reducing waste generation, ideally to zero) is the most desirable because it eliminates waste at the source, avoiding the need for reuse, recycling, or disposal. Reuse and recycling are secondary, and disposal is the least desirable as it often involves landfilling or incineration with environmental impacts.

Answer:

B. Prevention (reducing the amount of waste generated, ideally to zero)
