Students from IES Comarcal made a research about the waste generated at the school. COMENIUS project 2013-2015

1. Waste production
at the school
A research made by students from
IES Comarcal, Burjassot (Spain)

3. How much
waste do we
produce in our
school?

4. A collaborative
work:
● Comenius team
● Students from
2nd A,B

5. Let’s get down to work!

6. Students from 2A and 2B picked up all the
waste produced in one day.
Waste was collected in classrooms, corridors, teachers’ offices,....

7. ….and also in the playground

8. Bags were emptied

9. ...and the waste
was separated.

10. Paper, plastic, aluminium and organic matter.

11. Then, they weighed...

12. ...all the different types of waste

13. These are all the bags of the different types of waste that
were collected in our school in one day

14. This is what
we found out

21. How do we produce so much paper waste at
our school?
● When we use paper for notes and then throw it away.
● When we don’t use both sides of each sheet of paper.
● When we use cardboard and other
paper materials in subjects like
art and technology.

22. What is paper made of?
Paper is made of cellulose fibers, wood
(trees), filler, water and chemicals.

23. In response to the results from our school
1 tree 58.85 kg of paper
17 trees 1 ton of paper
IES Comarcal survey results
969.68 kg of paper waste/58.85kg = 16.48 trees in one year

24. This means that all the
paper we throw away in
one school year amounts
to 16,5 trees!!

25. What can we do?
● We can reduce the consumption of paper.
● We can re-use paper for notes or we could re-use it
to make funny arts and crafts.
● We can recycle paper by
throwing it to into the
correct container.

26. Advantages of recycling
● We will save some trees from being cutted down.
● Energy consumption is reduced by 65%
● If we recycle 1 kg of paper, we will
save 270L of water.

PLASTIC 2,80 498,4 22,88%

29. How do we produce so much plastic waste at
school?
We produce plastic when we throw bottles,
snack bags, pens, tipex, etc... into the bin

30. What is plastic made of?
Plastic is made:
● directly from oil
● by using residues of recycled plastic containers
● from renewable biomass sources
(corn and pea starch)

31. Impacts on the environment due to the
production of plastic
Factories pollute
● water (liquid residues)
● air (by emitting CO2 and other gases)

32. The time it takes for plastic to be destroyed
by nature
Plastic dolls:
300 years
Plastic bags:
500 to 1000 years
Plastic bottles:
100 to 1000 years
Yogurt pots, plugs
and straws:
100 years

33. What is saved by recycling plastic?
1 kg of recycled plastic saves
● 1 kg of Ethylene
(a petroleum derived substance)
● 39.3 L of water
● 2.5 kg of CO2
● 5 kw of energy

34. In response to the results from our
school
If we reduce the use of plastic or we use
recycled plastic, in one school year we will
save:
● Almost 500 kg of Ethylene
● 19.500 L of water
● 1.250 kg of CO2
● 2.500 kw of energy

35. What can we do?
● Use reusable bags
● Replace our plastic water bottle
for metallic ones
● Bring our snack in plastic lunch boxes
instead of in plastic bags or tin foil.

38. How do we produce aluminium waste at our
school?
We produce it with
the tin foil we wrap
our sandwiches in.

39. What is the tin foil made of?
It is mainly made of a mineral called Bauxita
Bauxita

40. Impacts on the environment due to tin foil
production
Mining Bauxita greatly impacts
● our landscape
● the ecological balance
(by damaging species)
● water in rivers and lakes
● human being’s health

41. The time that nature needs to destroy
aluminium waste
Nature takes 10 years
to convert a can into iron oxide.

42. What is saved by recycling aluminium
1 Kg of aluminium = 4 Kg of bauxita
1 Kg of aluminium = 6.9965 Kg of carbon dioxide
1 Kg of aluminium = 16.0 Kw of energy

43. Following the results of our school
If we reduce the use of aluminium we would
save:
● 342 kg of bauxita
● almost 600 kg of CO2
● 1.370 kw of energy

44. What can we do?
● Reduce the consumption by using other
packagings for snacks
such as re-usable plastic
containers.
● Reduce the consumption
of canned products.

47. How do we produce organic waste at our
school?
We produce organic waste at school when we
throw our un-eaten sandwiches into the bin.

48. What can we do?
Bring a smaller sandwich or
have a bigger breakfast.

49. CONCLUSIONS
As you have seen, we must use these materials
more wisely, because little by little we are
destroying the environment.
For this reason we must use the three Rs rule:

50. educe

51. e-use

52. ecycle
