Monroe County / Ridgeville Landfill

After all the cells in a landfill are used and are full, then we start the process of reclaiming. The idea is that the space on top of the landfill can be used for other purposes. Whatever is the type of landfill, the space on top of it is covered by layers of dirt, to recreate reusable soil. The space is compacted, and it is made sure to be leakproof so that there is no spillage onto the environment.

There are specific laws that regulate the use of landfills after being full and there are specific measures to be taken and to assure compliance. For chemical and garbage that is hazardous, there is a synthetic material that covers it. There is an intricate drainage system. For general garbage, there is a liner system at the bottom area of the cells. The top is covered by topsoil, clay, and synthetic materials.

After this has been done, the space on top of the landfill can support various uses. It can be used to create parks, As of right now, there are more than 1000 parks in the USA that originated from landfill places. The area on top can be used to generate electricity and attach solar panels. This idea is a bit dangerous as the ground below can shift during the years. The area on top of a landfill can even support wildlife habitats, as the layers of clay and dirt that cover the landfill can support and grow trees.

Chemical landfills are a variation of sanitary landfills. Chemical landfills are made to secure and hazardous waste. This type of landfill is made on top of a nonporous bedrock. The idea is to create a place that is specialized to reduce the likelihood of hazardous waste reaching the environment. This type of landfill has a pit with a heavily protected bottom that does not allow hazardous materials to reach the soil. These landfills are operated by specialized personnel, and they have strong monitoring systems. To deposit materials in a chemical landfill, it is mandatory to research the local applicable laws and any federal laws that pertain to the type of waste that you intend to dispose of.

Sanitary landfills offer a more advanced waste management approach that further reduces the chances of environmental contamination. The basic unit of a sanitary landfill is still the cell. The idea is to create soil tranches. The garbage is deposited onto layers 1 to 3 meters high and then compacted by bulldozers to reduce the volume. Then the garbage is covered by a layer of dirt. Multiple of these layers are piled together until they reach maximum capacity and thus, we form a cell. The cell is then reinforced on all sides to prevent leakage to the soil.

There is an interesting type of landfill, inert landfills. This type of landfill receives sand, concrete, and other waste related to construction. This type of waste does not have any biohazards nor decomposes, or it does so very slowly. These types of waste neither produce liquid waste. In this category, we mostly have asphalt, rocks, bricks, yard leaves. In this category, we do not include demolition waste.
