The document discusses the reuse and recycling of construction and demolition (C&D) waste, highlighting the composition of this waste in India, which is estimated at 24 million tonnes in 2010. It emphasizes the importance of waste sorting and the environmental benefits of reducing concrete waste, including cost savings and resource conservation. Additionally, the document notes that while developed countries recycle C&D waste into materials for new construction, many developing countries continue to dump this waste.

4. INTRODUCTION
o Construction waste recycling is the separation and recycling of
recoverable waste materials generated during construction and
Demolition (C & D).
o C&D waste in India in 2010 may be estimated as 24 million
tones.

8. Waste generated from construction industry
Inert material
Rocks, Concrete, Bricks, Stone, Earth.
Non inert material
Plastic, Packaging waste, Paint.
On site waste sorting
• segregate inert and non-inert materials
• segregate materials such as Paper, plastic, timber, metals, masonry, concrete
and excavated soil

9. Benefits of reducing of Concrete waste
– Reduce cost of aggregates
– Reduce disposal cost
– Environmental degradation prevented
– Reduce consumption of natural resources
– Life span of landfill area will increase
Concrete
Concrete is a mixture of sand, cement, aggregate, water, & admixtures

11. Stone/Marbles
How the waste is generated ?
The stone/marble which came from the quarry was not of a perfect size
and shape which is likely to be used in work, so we have to cut the
stone/marble in desired shape and size as per our requirement. After
cutting the excess portion has no further use hence waste is generated .
11

12. Reuse of the waste
oIn most cases the stone waste is used as filler material in road construction.
oThe marble waste sometimes used in terrazzo flooring.
oIf there is no reuse of stones/marbles they are dumped/sell to other agencies.
12

13. Timber
How the Waste is generated?
•Timber is generally used as framework for building concrete structures,
with passage of time it become soft due to contact with moisture of
concrete.

14. 14

15. Reuse of the waste
oIt is mostly crushed into chip & used as fuel.
oIt can be utilized to manufacture wood-chip concrete by injecting
cement grout into voids of compacted wood-chips in moulds.
oWood-chip concrete can be used as building material.
15

16. Sand
How the waste is generated ?
o The sand which came from the quarry was not of a perfect size which is
likely to be used in work, so we have to sieve as per our requirement.
o After sieving the remaining sand has no further use hence waste is
generated.
16

17. Steel
How steel waste generate ?
o Most of steel waste is generated during demolition, around 70% to
80% of all steel waste.
o Due to corrosion.
o Waste in terms of bent Nail.
o Small Pieces of G.I. pipes.

19. Brick
How waste generate?
o The Brick Waste is generated in the form of Bats and Small Pieces
o While loading from the manufacturing unit to the unloading at the Site,
there is possibility where the Bricks get broken and turn into bats and
the small pieces

21. Plastic
How plastic waste Generate?
• Cement bag
• Cover material for flooring
• Pieces of pipe.
P.O.P
How P.O.P waste generate?
• During ceiling work.
Ceramic
How it generate?
• During transport .
Reuse of plastic waste
• Joint the plastic bags of cement & use as
curtain for protection of neighbour property.
Reuse of P.O.P waste
• It only use as filler.
Reuse of it
• For flooring of terrace as a china mosaic.

23. Summary:
o It has been established that materials & components from demolished
buildings are being reused for new construction works as well as
renovation projects, especially by low-income communities in developing
countries like India.
o In developing countries most of the demolition rubble is dumped, the
developed world has now started to recycle it into aggregate for non-
structural concrete.
23

24. o Reducing consumption of natural resources like energy & reduces
usage of landfills.
