Which term describes wastes that take decades to thousands of years to break down in the environment?

• A. Non-biodegradable Wastes
• B. Slowly Degradable Wastes
• C. Liquid Hazardous Waste Disposal
• D. Safe Drinking Water Act

Answer: (B)

Wastes that take decades to thousands of years to break down in the environment are described as slowly degradable wastes. These materials do degrade eventually, but at an extremely slow rate, so their presence persists for a very long time under natural conditions. This places them between truly biodegradable wastes, which break down relatively quickly by microorganisms, and non-biodegradable wastes, which do not break down appreciably through natural processes and can persist for very long periods, sometimes indefinitely. The concept helps explain why plastics and some synthetic materials accumulate in landfills and ecosystems despite being subject to natural weathering and microbes. The other options describe regulations or disposal concepts rather than how fast a material breaks down, so they don’t fit the idea of slow degradation.
