Harris County Inert Landfill & Transfer Station

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.

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.

The first step onto the waste stations is to weigh the incoming garbage trucks. These sites are also open to the public and they help the community. The work of waste sorting stations is very important, and it helps to optimize the process of waste management. Transfer stations pre-compact the waste thus it is easier for the bulldozers to manage the waste at the sanitary landfills.

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.

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.
