What thickness of plastic is recommended for disposing of carcasses in a landfill?

• A. 1-mm
• B. 3-mm
• C. 5-mm
• D. 7-mm

Answer: (B)

Choosing the right plastic thickness is about getting a dependable barrier that stays intact during handling and disposal. A liner that’s too thin often tears or punctures when the carcass is moved, which can lead to leaks, strong odors, and exposure to workers and the environment. While thicker plastics do give more protection, they also add cost and can be harder to manage without delivering proportional benefits for typical landfill disposal.

A 3-mm thickness provides a practical balance: it’s strong enough to resist tearing and puncture from ordinary handling and the weight of carcasses, while remaining affordable and easier to handle. This level of thickness reduces the risk of leaks and contamination, supporting safer and more sanitary disposal. Always check local landfill guidelines, but 3-mm is commonly recommended as an effective standard.
