HOW WE GENERATE WASTE

We humans love buying things. We buy things for our daily needs like food, clothing, home including health care. However, most often we buy things that we don't really need. Once the object is no longer of any use, we simply discard them for not being useful like food packaging, bottles and even left over food directly to trash bins without proper segregation. These discarded materials are called waste.

When do we consider something as waste?

Material is considered waste if the object is no longer of any use. There are even cases where waste are left cluttered on the streets. Waste may differ in size but nevertheless, waste is still waste. Example of waste may include, candy wrapper, plastic container or old rusty vehicle.

  • mixed with another waste material - the whole mixture will be waste
  • deliberately and illegally abandoned or dumped, for example fly-tipping
  • accidentally, unknowingly or involuntarily discarded, for example when a fuel is leaking from a service station storage
  • tank into the ground beneath and the producer or holder is unaware of the leak
  • required to be discarded by law

What Are The Sources of Waste?

There are several sources of waste and they are classified into 4 different sources.
