GROWS North Landfill

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.

There is one detail to clear out. Landfills and dumps sound the same but are not. A landfill is engineered to maximally reduce the effect on the environment of the waste. The advantages of landfills over dumps are that landfills are managed with more care and landfills can even recycle the waste to produce other compounds or to even produce energy. Dumps are almost nonexistent today as they do not manage the waste and just leave things in the open.

Each landfill has a different cost to use its services. The price depends on many factors, such as type of waste ( hazardous, construction and demolition waste, municipal solid waste, and inert waste ), location of the landfill, and the individual charges of the landfill. According to statistics, the USA average price per ton is $53.72. The costs tend to be higher in the Pacific area, where they reach an average of $72.02 per ton of waste. The prices are averagely the cheapest in South Central, where they reach $39.66 per ton. From statistics, we see that the highest populated areas, the Pacific and the northeast are the costliest, while the other areas of the USA tend to have cheaper prices per ton.

There is a lot of waste generated in the USA. In 2018, there were 292 million tons of waste generated. Averagely that is 4.9 Lb. of waste per person. The waste from municipalities is recycled the most. The data says that in 2018, there was a recycling rate of 32%. Some of the waste is reprocessed not other means such as bio-chemical management.The largest categories of waste pertain to paper, food plastics, yard trims, and metals. Food, plastics, and paper make are the main resources for energy production from waste.

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.
