Which term refers to the use of source reduction and/or environmentally sound recycling methods prior to treating or disposing of hazardous wastes?

• A. Waste minimization
• B. Recycling
• C. Reuse
• D. Recovery

Answer: (A)

The main idea here is reducing hazardous waste at the source and using environmentally sound recycling methods before any treatment or disposal is needed. This is waste minimization: it focuses on preventing waste from being created in the first place, through changes in processes, material substitutions, and careful recycling that minimizes generation of hazardous waste. By addressing the problem before it becomes waste, you avoid the need for treatment or disposal later. Recycling, by contrast, generally refers to processing materials after they have become waste to recover usable material. Reuse means using the same item again, often without significant processing. Recovery usually means extracting energy or materials from waste after it’s generated. These are important practices, but they describe steps taken after waste has already been created, not the preventive approach emphasized by waste minimization.
