When waste arrives in a landfill it needs to be sorted out first. Therefore, we have waste sorting stations. These are specialized for municipal waste and not for other types of landfills. Garbage trucks dump their municipal waste. Then the waste is separated into recyclable waste and non-recyclable materials. The non-recyclable garbage is then separated into hazardous waste, energy recyclable waste, landfill waste, or incinerator waste. Afterward that it has been sorted out, it is then loaded onto garbage trucks, and this deposits the waste onto their designated places.

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.

A landfill has very detailed business operations. The waste arrives at the facility in garbage trucks on a section called the Cell. The cell is made of an isolated layer, that prevents any waste or liquids from leaking. In the cell, the waste is sorted out. This unit is enclosed, as the sun and the atmospheric conditions can interact with the waste. Afterward, the garbage is compressed in the smallest volume possible. The cell will accept new waste until it is full. When it reaches, it is further reinforced on top with various materials and dirt. The idea is that the area on top of the cell is reused and to support vegetation.

The important part of this process is the base of the cell. It must prevent liquids and other pollutants from reaching the soil. For this reason, the cell is isolated below with layers of plastic and clay, to create a strong isolation system.

Regarding liquids, they are collected onto a unit called the sump. In this unit, the liquids are processed, and when they are cleaned on pollutants, they are reintroduced onto the environment. Each landfill has groundwater monitoring, which means they collect the quality of groundwater before it reaches the landfill and afterward it exits the landfill. Regarding gasses generated by the waste, they are collected via a special system that ends up reusing the methane generated and the gases to produce energy.

When a landfill reaches the point that all the cells are full, then the landfill stops operations. This doesn’t mean that the owners of the landfill have no responsibilities. They must be monitored for 30 years after closure, and that means assuring the quality of groundwater and preventing leakage to the soil of any type of 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.

The schedule of each landfill differs and they different hours of operation. To find the opening hours regarding a specific landfill, you use the above site. After you have located the desired landfill to use, the operating hours can be seen on current page of site after clicking into the “Opening hours” section. There you will be able to locate the opening hours and any other facts about the business services of the landfill.
