How Can We Make Landfills Safer for the Environment?

For years, garbage has been a major problem. Before, we simply throw our garbage out of our windows—literally overlaying the streets with our dirt, trash and filth. This method toiled when there’s several lands and a few people. However, the moment the cities and the populations grew, the problem about garbage grew tantamount also. From years 1920’s up to 1970’s, people have taken their trashes to the garbage dump—a huge hole in the ground where garbage and trash are buried—rather than throwing garbage out of their windows. Still, this system is not a long-standing resolution for the environment. In the year 1976, the U.S Congress approved the Resource Conservation and Recovery Act and it basically altered how we process and store our trashes and garbage.

Landfill governments and cities are trying their best to be more environmental friendly in terms of handling their waste and trash. Since 1993, federal regulations have obliged substitute daily covers—rain covers, ADCs or landfill cap covers in an act to enhance safety and health nearby the landfills. ADCs cover the landfills to uphold the sanitary conditions and avoid disease and vermin. Although garbage dumps were merely holes in the ground, landfills are now needed to be planned carefully, engineered, and monitored closely to be more efficient and environmental friendly. City planners and engineers should now focus into its long-term advantages before assigning an area to be made into a landfill; garbage dumps are no longer permitted for environmental, safety, and health reasons.

Moreover, a landfill is needed to be engineered and planned meticulously to separate the garbage from the surrounding environment like the groundwater supply. This is realized through utilizing a bottom liner also as a daily covering of day or soil. Scientists and engineers are aware that the long-term aftereffect of placing massive amounts of trash in one area could be devastating, thus, they are acting toward greater environmental alternatives to the issue about garbage. The EPA has been an instrument in making rules and regulations for landfill utility and design, needing the following layers for each landfill:

  • Layer of geotextile like synthetic preamble membrane, which is responsible for filtering out the trash from the water.
  • Layer of soil.
  • Water collection system.
  • Water-resistant clay to prevent any water that passes through the plastic layer.
  • Layer of plastic liner to stop leachate from moving towards the groundwater.
  • Special capping methods, which closes off the landfill from seeping dangerous gasses into the air.

The geotextile layer is beneficial for the efficient function and filtering of a landfill. A geosynthetic membrane cover similar to those manufactured by Western Liner could be critical in controlling dust, odor, lessening windblown litter, vermin and discouraging pests, enhancing the entire function and appearance of the landfill and peeling surface water more rapidly.

The federal government also found another way to try to create landfills safer for the environment. This is through being updated on the trends in energy generation from waste processes, recycling and composting and using that knowledge to state and city landfilling.

Recycling

With its higher focus of composting and recycling, the FDA is determined to mitigate the entire amount of solid waste accumulated through landfills. Now, our scientific advances and fervent commitment to preserve the environment, our rules and laws can simply enhance the country’s landfills and their construction.

We should keep on striving to make the best of our abilities so that we can preserve and protect our planet Earth and reimagine better means of handling our natural resources from the start to end.
