The ever increasing population of our earth has lead to an enormous production of trash trough residential, institutional, commercial, and industrial waste. Therefore, the education and awareness in the area of waste and waste management is increasingly important. It is critical and challenging for us to help save the earth’s environment from pollution through waste management and recycling programs by using innovative ways to keep the trash out of the landfills.
What is Waste management?
Waste management is the processing and recycling of waste collected, which may include solid, liquid, gaseous or radioactive materials. Landfills are generally used to dispose the waste by burying the waste material. To be hygienic, the landfill must be well-constructed and managed otherwise the landfills can create odor problems, kill surface vegetation, and is a greenhouse gas.
First, garbage trucks enter the facility and are weighed on a platform. They are inspected to make sure that only solid waste is within the truck. Next, the trucks enter a large garage and empty the waste into a giant pit. Air is constantly circulating into the pit and is used as combustion. The pit is sealed so that air is not able to leave, which prevents harmful gases, dust and allergens from escaping. Above the pit are cranes that lift the waste into hoppers. From there the hopper hydraulic shelves move the trash onto reciprocating shelves in a furnace. Overhead and below fires provide complete combustion to the waste. When exiting the furnace, farce metals such as iron and silver are separated from ashes of other items. The ash is safely placed in a nearby landfill.
