the needs of industrial ecology
To reduce
environmental stress
caused by industry
whilst encouraging
innovation, resource
efficiency and
sustained growth.

Improved
environmental
protection
Cost savings
(materials purchasing,
licensing fees, waste
disposal fees
Avoid resources
depletion for future use
Enhanced

the source of water
surface water
groundwater
catchment area
An extent of land where water from rain or snow melt
drains downhill into a water body, such as a river, lake,
reservoir, sea or ocean.
amount of water reaching the river
depends on
The size of the area.
The amount of precipitation
The loss through evaporation and absorption by the
earth
hydrological cycle :
1. Precipitation :
that falls from the atmosphere in the forain or
snow: :
2. Reaches the land surface
and recharges rivers, lakes,
wetlands, and other surface water bodies directly;
3. Infiltrates
(seeps into) the ground and eventually reaches the
ground water; or
4. Evaporates
back into the atmosphere.
Mass Balance Approach
:<3:
Accumulation of mass = Input of mass - Output of mass
What is EIA :lock:
A study to
identify, predict, evaluate and communicate information
about the
impacts on the environment of a proposed project
