6. Waste management refers to the practice of proper
waste disposal. Wastes refer to used or consumed
product or materials. A very good sample of this is
garbage. Waste management is implemented
anywhere in order to clean the environment and
make everyone healthy. Surely, you do not want to
leave a place full of garbage and wastes. Aside from
their foul smell, we do not want to get sick cause by
them. A kind of waste management we follow
nowadays is the 5R’s of waste management.
