Strategies for
Sustainable Use of Resources
The world's
natural resources have conflicting demands upon them and can be difficult to
manage. To conserve natural resources for future generations,
sustainable management of the natural environment is necessary. Alternative
resources might be developed in order to ease the strain on finite resources.
However, alternative resources can be expensive and take time to develop.
Existing resources could be used more efficiently, to prevent finite resources
being used up so quickly.

How to apply the strategy
|
Steel
|
Reduce:
|
Can be reduced by the use of concrete constructions
|
Reuse:
|
Certain materials are reused which are used in the
steelmaking process. Water used in steel plants is often processed and
converted to steam to generate electricity. The byproduct gas produced in
blast furnaces and coke ovens are also reused, that would otherwise be wasted
in the place of natural gas.
Steel is 100% recyclable and is highly recycled. Steel
products can be recycled over and over without losing any strength.

Water
|
Reduce :
|
We should reduce the usage to the minimum. Although we
cannot stop the necessary use of water, wastage of water can be eliminated.
We tend to waste water in many ways; over flushing, long baths, running taps
while filling buckets or simply leaving the taps open while we are busy doing
some other activity. These are some very generic scenarios that we do in our
day today lives.
|
Reuse:
|
Instead of letting the used water go down the drains we can
redirect it for reuse. The used water from bath, laundry or sinks is known as
greywater. This can be treated at different levels for removing chemicals
from them and can be used again. The water from the sink or bath can be used
for mopping, car washing, irrigation of plants, and other non-potable
activities. This will decrease the pressure on the fresh water required for
these activities.
|
|
Recycle:
|
Rainwater, which is a source of fresh water, is drained
down the sewer lines making it unusable. This rainwater can be harvested to
balance the underground tables to combat drought situations. Farms and
gardens can be irrigated with this water. It can also be used for non-potable
activities of our daily routines.
|
|
Timber
|
Recycle:
|
Timber recycling or wood recycling is the process of turning waste timber into usable
products. Recycled timber most commonly comes from old buildings,
bridges and wharfs, where it is carefully stripped out and put aside by
demolishers. At the same time any usable dimension stone is set
aside for reuse.
|
Glass
|
Reduce:
|
Since we do not generate very much glass waste, reduction
isn't a big priority. The only alternative for glass is plastic, which is
certainly less desirable than glass.
|
Reuse:
|
Much of the glass waste that we do have ends up being
reused. In the past this has been especially true for larger containers, such
as pickle jars.
|
|
Recycle:
|
The glass that we don't use is always recycled. This is
mostly bottles, such as those that essential oils come in, although those
might soon get used for tinctures as well. Unlike many other materials, particular
glass item can be recycled.
|
|
Lime Stone
|
Reuse :
|
Use them to dust off out-of-season
shoes and out-of-favor stuffed animals stored in the closet. Make
parachutes for action figures to heighten the adventure at playtime. Cut out
a square from a bag, and poke a hole in each corner. Cut four pieces of
string at least a foot long and loop one through each hole, tying a knot to
secure it; tie the other end of each string around the toy.Keep bags
in the glove compartment to use as trash bags on road trips―or, if you have
kids, trips just down the road.
|
Recycle :
|
Plastic recycling is the process of recovering scrap or waste plastic and
reprocessing the material into useful products.
