Which material is commonly repurposed as landfill cover in beneficial use practices?

Concrete debris is commonly repurposed as landfill cover in beneficial use practices due to its density, durability, and structural properties. When concrete is processed and crushed, it creates an aggregate material that can effectively provide a stable and effective cover over waste layers in landfills. This layer helps to minimize odors, control pests, and mitigate environmental hazards by preventing exposure of the waste to the elements.

Moreover, using concrete debris as cover aligns with sustainable practices by diverting materials from landfills that would otherwise contribute to waste accumulation. It also reduces the need for natural resources, as it allows for recycling within the waste management system. Other options like metal scraps, textile waste, and oil waste may have potential environmental concerns or do not provide the same structural benefits needed for effective landfill cover.
