Waste management includes the activities
and actions required to manage waste
from its inception to its final disposal.

Waste can be solid, liquid, or gaseous
and each type has different methods of
disposal and management.

Waste management deals with all types
of waste, including industrial, biological
and household. In some cases, waste
can pose a threat to human health.

Health issues are associated throughout
the entire process of waste management.
Health issues can also arise indirectly or
directly. Directly, through the handling of
said waste, and indirectly through the
consumption of water, soil and food.

Waste is produced by human activity, for
example, the extraction and processing
of raw materials. Waste management is
intended to reduce adverse effects of
waste on human health, the environment,
planetary resources and aesthetic.

Waste management practices are not
uniform among countries (develop and
developing nations); regions, and
residential and industrial sectors can all
take different approaches.

Proper management of waste is important
for building sustainable and livable cities,
but it remains a challenge for many
developing countries and cities.
