After finishing your popcorn and cold drink, you throw away the paper bag and the crushed drink cup into the trash can. Have you ever thought where all the waste will go? Every time we throw away our uneaten food, food wrappers, used napkins, we are increasing the level of our trash. Americans gather trash at an amazing rate of 4.6 pounds per day per person. And all this trash goes to our landfills.

So, what is the definition of landfill? A landfill is a site used for the disposal of the waste material by burial or other methods. Landfills are the most common and traditional way to organize the waste disposal. As the overall level of waste disposal increases, some landfills are transferred into waste management plants. Waste management process includes temporary storage of the waste material, merging and transfer, and processing of waste material like recycling, treatment, etc. In some modern liquid waste management plants, liquid wastes are also used to generate power. In order to manage the waste disposal ground in the above mentioned processes, some technical operations are performed there. These operations are:

  • Keeping the waste confined in a smaller area.
  • Wastes are compressed to reduce their volume.
  • Cover up the waste on a daily basis using soil layers.

A waste disposal ground can cause various problems. It can damage a road so that no heavy vehicle can use it. It can pollute the soil or ground water by any leakages. Also, unmanaged landfills can grow viruses or bacteria that carry diseases. It can increase pollution to the surrounding environment.

Every landfill has a certain capacity. Above that it can’t store waste. And an unattended landfill with waste material will only cause problems. So, what will people do with a full landfill? When a waste disposal ground is full, it is generally capped with layers of resistant clay or plastic or soil. Using certain methods, full waste disposal ground is used for vegetative growth or creating landscape garden or parks.

Now, with the advancement of technology, the traditional way of covering a landfill with soil has gone, because this system is costly, and has weather related issues. Currently, to close a landfill, artificial or synthetic closure systems can be used. These systems are less costly, require fewer resources, are easy to maintain and offer better protection than the previous one.

One of the synthetic systems is called LiteEarth. LiteEarth landfill capping composite is made up of an EPDM geomembrane and synthetic grass. The EPDM is an impermeable membrane which protects the landfill, and they artificial grass provides aesthetic benefits. This fake grass needs no trimming, planting or watering.  LiteEarth also provides air space benefits because it is a thinner, more light weight alternative than soil landfill caps. Due to the above advantages, it is commonly used for landfill capping. Using this artificial grass and EPD<, we can convert a waste disposal ground into a landscape garden or a sports complex or park, and can keep the environment clean and beautiful.
