1. Definition of hazardous waste
A Hazardous waste is waste that has a
potential threats to public health or the
environment.
The remnants of the various activities and operations or

that have no subsequent original uses, such as clinical
waste, and waste resulting from the manufacture of any
of pharmaceuticals and drugs, solvents or inks, and
Paints.
Sources of hazardous waste: Domestic activities agricultural - commercial - industrial.
Improper management of industrial
plants..
May lead to the presence of hazardous waste
.... have a detrimental effect on health and
the environment.
So, there is a need for actions to be taken
during the various stages of wastes
generation to get rid of them.
