In this ppt you are going to see some waste management staratergies

2.  UO (Unit outcomes)/LO(Learning outcomes)
1.e Describe various environmental issues.

3.  4R
 It is waste management strategies
 1.Reduse
 2.Reuse
 3.Recycle
 4.Recover

4.  Applying 4R means questioning our daily
acts, the things we do mechanically, without
thinking of consequences without thinking of
the environment.
 Applying the 4R means consuming
intelligently thus making substaintial
savings(in terms of money, time, pollution,
waste and energy)

6.  1.If we avoid making garbage we need
not worry about disposing of waste.
 2.Changing the habits of shopping ,
working and playing can reduce our
waste.
 3.We should use paper bags instead of
polythene bags.

7.  4.Reducing and recycling can save
natural resources and reduce waste
management cost.
 5.By designing manufacturing
,purchasing or using materials in
ways that generate less waste ,fewer
natural resources are used.

8.  1.Saves natural resources.
 2. Reduce toxicity of waste.
 3.Reduce cost.

9.  Reuse means thinking before deciding that
we are missing a product/object. the process
of reusing started with the assumption that
the used materials that flow through our lives
can be resource rather than refuse.
 Don’t I have something similar that I forgot I
have.
 Do I really need it.
 Can a friend or someone in my family lend it
to me.

10.  Containers can be reused at home or for
school projects.
 Reuse wrapping paper plastic bags , boxes.
 Buy beverages in returnable containers.
 Try repair before you consider replacing tools ,
TVs etc.
 Donate broken appliances to charity sheets .
 Offer furniture and household items no longer
needed to people in need, friends or charity.
 Old tires can be used in garden.

11.  By recycling waste objects are brought back
in to a state of raw material . like waste paper
becomes pulp , plastics are melted and
molded in to new products and so on.
 Collecting used bottels,cans and
newspapers and taking them to collection
facility.recycling of a material may produce a
fresh supply of same material.
 Sometimes recycling is difficult or too
expensive

12.  1.Recycling reduces the consumption of fresh
raw materials.
 2.It reduce energy usage.
 3.It reduce air pollution.
 4.It reduce water pollution.
 5.It lowers greenhouse gas emissions

13.  1.The costs and energy used in collection and
transportation.
 2.The jobs produced by the recycling industry
can be poor trade for the jobs lost in logging,
mining and other Industries.
 3.Materials such as paper pulp can only be
recycled a few times before material
degradation prevents further recycling.

14.  Recover is to convert waste in to resources
through thermal and biological means.
Resource recovery occurs after reduce , reuse
and recycle .
 Recovery is when most of the mterial thrown
as garbage is used and processed in ways
other than being destroyed.
 When it is not possible to reuse or recycle
objects such as mobile phones , computers,
televisions and other electronic gadgets,
recovery is the last option.

15.  The waste is sent to scrap dealers can be a
source to recover gold and silver from the
contacts , copper from PCBs .all the metal
from castings, plugs, and sockets which can
all be reused.

16.  Concerned with day today interaction with
surroundings.
 It is interdisciplinary field.
 It is concerned with the importance of wild
life its protection.
 It explains the significant role of biodiversity
in establishing ecological balance.
 It deals with different types of ecosystems ,
biotic and abiotic factors their role in
ecosystem

17.  It is concerned with different types of food
chains food webs,productivity.
 It explains the coexistence of both living and
non living organism and their contribution to
nature.
 It gives information about water
conservation,watershed management and
importance of ware as universal solvent.
 It explains importance of sustainable
development

18.  4R
 Reduse-Advantages
 Reuse
 Recycle-Advantages,disadvantages.
 Recover.
 Importance of EVS
