From the garbage bins and dumping sites, garbage is collected by municipality workers. They use a huge garbage truck for this. The garbage is then taken to a landfill site.
A landfill site is usually made away from residential areas. The garbage often contains some useful items and some non-useful items. Items which can be recycled are separated and sent for recycling. Other items are left on the landfill site. Once the landfill site fills with garbage, it is covered with soil. It is left for at least 20 years before any construction can be allowed on the landfill site. Landfill site is ideal for making parks and playgrounds.
