As part of waste reduction, which action should be taken with cardboard?

• A. Dispose of cardboard with regular trash
• B. Recycle cardboard
• C. Burn cardboard for energy
• D. Store cardboard indefinitely

Answer: (B)

Recycling cardboard supports waste reduction by diverting material from landfills and conserving natural resources. Cardboard can be turned into new paper products, and this use of recycled fiber generally requires less energy and water than producing virgin paper. It also frees up space in waste streams and reduces emissions from landfill decomposition. In a grooming or shop setting, flattening and recycling boxes helps keep the workspace tidy and ensures more cardboard gets recycled. Other options—disposing with regular trash, burning for energy, or storing indefinitely—do not reduce waste as effectively and can have negative environmental impacts.
