Alternative daily covers play an important role in limiting access by vectors such as birds, insects, and rodents. By sealing the waste each day, they remove food sources and reduce open areas where pests can feed, nest, or breed.
Synthetic liners and tarps create a physical barrier that is difficult for animals to penetrate, while dense organic or shredded materials make it harder for insects and rodents to reach the waste. Controlling vectors is essential for public health because these animals can spread disease and carry debris outside the landfill. Effective coverage also helps prevent birds and other animals from scattering waste, reducing litter in surrounding areas.
