19. Recycling is a process to convert waste materials into
reusable material to prevent waste of potentially useful
materials
Why we choose this idea?
We've taken our idea because we found that Qatar spent annually 2.5
million tons of garbage a year, including glass , plastic , metal and
paper.
The significance of the project is to:
1-Help Qatar to get rid of the garbage.
2-concrete industry a powerful but cheap cost.
3-If those concrete excessive can be exported to developing countries it is
not capable of high concrete industry cost or imported.

20. Material we used:
 120(g) cement 120(g) Powder paper
 120(g) glasses 33(g)water
 Metal and plastic at the reinforcement.
The project uses:
1- build houses and
walls .
2-make roads.
Product benefits:
1-garbage disposal and environmental protection.
2-existence of cheap concrete.
3. Contribute to the external economy by exporting
these concrete to developing countries.
