Construction industry is one of the biggest sector in India with increasing demand. We need to take certain actions and precautions on site to reduce construction waste. Metro cities like Pune, Mumbai and Bangalore etc. are most congested cities. So, the need of flats, apartments, row houses etc. is increasing with higher rate. We need to demolish the existing old structures and build new structures to have the maximum space for environmental purpose. So, there is increasing in demolition waste as compared with construction waste. There should be certain provisions for the checking of this waste management cycle to prevent its impact on environment. Construction and demolition waste can be classified into 2 components; major components include cement concrete, bricks, cement plaster, steel from RCC, doors & windows, roofing support systems, rubble, stones, timber etc. and minor components includes conduits, GI pipes/Iron pipes/Plastic pipes, electrical fixtures, panels, glass etc. Please view presentation for detailed report.

3.  Construction industry is one of the biggest sector in India with an
increasing demand.
 However with huge construction in process, Construction and
demolition waste is the area which face major problem now a days.
 In India, rate of construction and demolition waste goes on increasing
due to oblesence, demolition for new construction etc.
 The rules and regulations laid down by local bodies to reduce waste
amount are present and it is necessary to reduce to the amount of waste,
 There is need of waste segregation, recycling and reuse. There should be
certain provisions for the checking of this waste management cycle to
prevent its impact on environment.

Sr.No. Author Conclusion
1 Markandeya Raju
Ponnada and
Kameswari
It suggests improved methods of
recycling/reuse/disposal of demolition waste
and modifications required in regulations in
vogue for demolition waste disposal.
2 Job Thomas And
Wilson P. M.
Waste minimization and waste management
programs are in its infancy in India. It is
possible to minimize the volume of C&D
waste generated by identifying the potential
waste early in the design.
3 Mr. M.
Sankarnarayanan
C&D wastte can be effffecttiivelly used in
severall ways:
As inert fill materiel for low-lying areas,
landscaping
Processed C&D wastte can be used for road
and
embankment construction

4 Sandeep Shrivastava
and Abdol Chini
3Rs policy and use of waste minimizing technologies
e.g. design for deconstruction and
reuse of materials should be adopted to minimize C&D
waste.
5 Vilas Nitivattananon Currently, existence of regional and national policies,
laws and regulations governing 3R principles
for C & D waste is minimal in Asia.

To optimize proper functioning and formulation of a
project, C & D Waste Management Plan must start at
the earliest possible stage of the project.

The paper has established that unauthorized siting of
buildings is primarily the result of socio-economic,
political,
institutional and physical factors.

6. Aim
 To understand present scenario of construction and
demolition waste management cycle.
 To analyze the construction & demolition waste
generated on site using Relative Importance (RI) index.
Scope
 Economy in waste management cycle.
 Useful in research work under construction and
demolition waste management project.
 More importance to waste reduce, reuse and recycle.

8. Present Scenario of C & D Waste in
India
 Construction industry is one of the fastest growing industry in India.
 Presently, awareness of resource-efficient construction practices is lacking
in most countries.
 The wastes are being disposed off improperly and illegally in order to
avoid transportation and tipping costs.
 As per report submitted by Dr. K. N. Satyanarayana to the Chennai
Municipal Corporation, about 12 million tonnes waste is generated per
annum.

Parameters
Sr. No. Parameters
1 - Efforts to reduce waste
2 - Waste segregation
3 - Achieve economy in waste management
4 - Steel reused
5 - Wood reused
6 - Bricks reused
7 - Concrete reused
8 - Waste disposal on land
9 - Use of remaining waste
10 - Use of waste material compared with fresh material
11 - Aware about C & D waste management rules
12 - Taken the help of local authority for waste management

12. RI Index
12
Relative Importance Index or weight is a type of relative importance analyses.
RI is used for the analysis because it best fits the purpose of this study.
Particular variable makes to the prediction of a criterion variable both by itself
and in combination with other predictor variables.
In the calculation of the Relative Importance Index (RI), the formula below
was used:
RI = ∑ W / A.N
Where,
W—weighting given to each statement by the respondents and ranges from 1
to 5;
A—Higher response integer (5); and
N—total number of respondents.

13. 13

14. Conclusion
 As we have seen that parameter no. 12 got the
maximum RI index. Means currently most sites don’t
take the help of local body for waste management.
Similarly for other parameters we have determined
the RI index for analysis.
 Parameter no. 11 got 0.81 RI index stating that most
sites are unware about C & D waste management
rules.
 So as far as all parameters are concerned, the present
condition of C & D waste management is critical with
lots of efforts must be planned.
 This analysis gives the idea about priority given to the
particular parameter. There is a need for effective
planning and disposal of waste. There is a lack of
communication between local authority and
construction body.
