Answer explanation

The most effective way to reduce waste is to exercise wise buying. Buy only what is

important and needed.

If the production of waste is unavoidable, find another way for some of it to be useful again. Instead of throwing the garbage right away, you can use them again for a different purpose, donate, or sell them.

If a material is not reusable, recycle it by turning it into another useful material. It is like giving a new purpose to a material that is supposedly meant to be thrown away.

Materials that are reusable sometimes wear out and become broken. If that happens, those materials should be repaired and not thrown away.

If materials cannot be reused, recycled, or repaired, then they may be recovered in the form of energy. All wastes that go straight to the landfill possess energy that may be retrieved with the help of technology.

is a facility where garbage and other waste materials are burned. In this

facility, the burnt garbage is converted to ash, heat, and gas.

It is giving a new purpose to a waste material instead of throwing it right away.

This is minimizing the number of waste materials produced by buying only what is important and needed.
