Question

Why do we need to provide escape vents in the case of a sanitary landfill ?

Answer 1

sanitary landfill is a pit with a protected bottom where trash is buried in layers, compacted (pressed down to make it more solid), and covered. A sanitary landfill can reduce harm from waste that has collected, and is safer than an open dumping site. But even the best sanitary landfill will fill up and, after many years, probably start to leak. To solve our waste problems, we still need to prevent waste in the first place.

It is difficult to turn open dumps into sanitary landfills. Instead, a community can build a new sanitary landfill and clean up the old site by transporting trash to the new one. A sanitary landfill protects community health when:

it is built away from where people live.it is covered to prevent insects and other disease-carrying animals from breeding.it has a lining of hard-packed clay soil or plastic to prevent chemicals and germs from contaminating groundwater.

Because building and maintaining a sanitary landfill is a lot of work, it usually needs to be done in partnership with the community, local government, and other organizations, such as churches or businesses.

A landfill protects community health only if it is well managed. Good management includes training and support for landfill workers, and working together with resource recovery centers, toxic waste collectors, and local government.
