2. background Municipal Solid Wastes (Management and Handling) Rules, 2000 published on 25th September, 2000 which provided a regulatory framework for management of Municipal Solid Waste generated in the urban area of the country. A draft rule, namely, the Solid Waste Management Rules, 2015 with a separate chapter on construction and demolition waste were published by the Central Government in the Ministry of Environment, Forest and Climate Change on 3 rd June, 2015 inviting objections or suggestions from the public within sixty days from the date of publication of the said notification. The objections or suggestions received within the stipulated period were duly considered by the Central Government. Thereafter, in supersession of the Municipal Solid Wastes (Management and Handling) Rules, 2000, the Central Government notified rules for Management of Construction and Demolition Waste and these rules are called the Construction and Demolition Waste Management Rules, 2016.

4. what is C&D Waste? Renovation 40% Demolition 50% New Construction 10%

5. Definition of C&D Waste “ C&D Wastes means the waste comprising of building materials, debris and rubble resulting from construction, re-modelling, repair and demolition of any civil structure “D e-construction” means a planned selective demolition in which salvage, re-use and recycling of the demolished structure is maximized “Demolition” means breaking down or tearing down buildings and other structures either manually or using mechanical force (by various equipment) or by implosion using explosives

6. Activities which generate C & D waste in cities / towns are mainly from: Demolition of existing, old dilapidated structures; Renovation of existing buildings (residential or commercial); Construction of new buildings (residential or commercial or hotel etc.); Excavation/ reconstruction of asphalt/ concrete roads; Construction of new fly over bridges/ under bridges/ sub-ways etc.; and Renovation/ Installation of new water/ telephone/ internet/ sewer pipe lines etc. Present collection and disposal system. Activities which generate C&D wastes

8. WHAT DOES C & D WASTE CONSISTS OF? Concrete Brick Timber Sanitary ware Glass Steel plastics

9. Main Issues for C & D Waste Management Absence of segregation of waste at source Lack of appropriately located recycling facilities Indifferent attitude of citizens toward waste management due to lack of awareness. Illegal landfill practices done by contractor for saving money.

10. Key Requirement of C&D Waste Management Plan Types, quantities and qualities of wastes Measures for reducing waste generation On-site waste sorting On-site and off-site reuse Areas for waste storage Quantities of wastes requiring off-site disposal Monitoring and auditing program

11. Hierarchy for C & D waste management

12. Environmental Impacts of C&D Wastes Landfill leaks (plasterboard release H 2 S) C & D makes municipal waste heavy Degrade the quality of municipal waste & makes it difficult for further treatment like composting 10-20% finds its way into surface drains, choking them Other toxic elements such as lead, asbestos & radioactive materials that can leak and pollute the water bodies Air pollution

15. WASTE GRENERATOR – Meaning “Waste generator” means any person or association of persons or institution, residential and commercial establishments including Indian Railways, Airport, Port and Harbour and Defence establishments who undertakes construction of or demolition of any civil structure which generate construction and demolition waste. Duties of the waste generator – (1) Every waste generator shall prima-facie be responsible for collection, segregation of concrete, soil and others and storage of construction and demolition waste generated, as directed or notified by the concerned local authority in consonance with these rules.

16. DUTIES OF WASTE GENERATOR (2) The generator shall ensure that solid waste does not get mixed with this waste and is stored and disposed separately. (3) Waste generators who generate more than 20 tons or more in one day or 300 tons per project in a month shall segregate the waste into four streams such as concrete, soil, steel, wood and plastics, bricks and mortar and shall submit waste management plan and get appropriate approvals from the local authority before starting construction or demolition or remodelling work and keep the concerned.

17. Duties of the Waste Generator Every waste generator shall keep the construction and demolition waste within the premise or get the waste deposited at collection centre so made by the local body or handover it to the authorised processing facilities of construction and demolition waste; and ensure that there is no littering or deposition of construction and demolition waste so as to prevent obstruction to the traffic or the public or drains.

18. Duties of the Waste Generator Every waste generator shall pay relevant charges for collection, transportation, processing and disposal as notified by the concerned authorities; Waste generators who generate more than 20 tons or more in one day or 300 tons per project in a month shall have to pay for the processing and disposal of construction and demolition waste generated by them, apart from the payment for storage, collection and transportation.

19. Estimation of C&D Waste Technology Information, Forecasting and Assessment Council's (TIFAC) has developed some estimations on C & D waste generation which recognizes that the generation is project specific as follows: Range 40-60 kg per sq.m of new construction, Range 40-50 kg per sq.m of building repair, Range 300-500 kg per sq.m for demolition of buildings. FIVE categories of existing C & D waste quantification methodologies are reported: Site visit method, Waste generation rate method, Lifetime analysis method, Classification system accumulation method and Variables modelling method

20. TIFAC Assessment In India, when old buildings are demolished the major demolition waste is soil, sand and gravel accounting for bricks (26%) & masonry (32%), Concretes (28%), metal (6%), wood (3%) others (5%). Excavations, concrete, masonry and wood together constitute over 90% of all C & D waste.

21. Criteria for storage, processing or recycling facilities for construction and demolition waste Construction and demolition waste shall be utilized in sanitary landfill for municipal solid waste of the city or region. Residues from construction and demolition waste processing or recycling industries shall be land filled in the sanitary landfill for solid waste. The processing or recycling shall be large enough to last for 20-25 years (project based on-site recycling facilities). The processing or recycling site shall be away from habitation clusters, forest areas, water bodies, monuments, National Parks, Wetlands and places of important cultural, historical or religious interest.

22. Provisions at the storage sites Utilities such as drinking water and sanitary facilities (preferably washing/bathing facilities for workers) and lighting arrangements for landfill operations during night hours shall be provided. In order to prevent pollution from processing or recycling operations, the following provisions shall be made, namely: Provision of storm water drains to prevent stagnation of surface water; Provision of paved or concreted surface in selected areas in the processing or recycling facility for minimizing dust and damage to the site. Prevention of noise pollution from processing and recycling plant: provision for treatment of effluent if any, to meet the discharge norms as per Environment (Protection) Rules, 1986.

23. Fines from construction and demolition processed waste having size up to 2 mm shall be used for daily cover over the fresh waste. During hot windy days in summer months, some fugitive dust problems may arise. These can be minimised by mixing with local soil wherever available for limited period. Use of construction and demolition fines as landfill cover shall be mandatory where such material is available. Fresh soil (sweet earth) shall not be used for such places and borrow-pits shall not be allowed. Exception – soil excavated during construction of the same landfill. storage, processing or recycling Practices

24. The following project shall be exempted from the norms of pollution from dust and noise as mentioned above: For construction work, where at least 80 percent construction and demolition waste is recycled or reused in-situ and sufficient buffer area is available to protect the surrounding habitation from any adverse impact. Work Zone air quality at the Processing or Recycling site and ambient air quality at the vicinity shall be monitored. The measurement of ambient noise shall be done at the interface of the facility with the surrounding area, i.e., at plant boundary. MONITOING FACILITIES at storage sites

25. Accident reporting by c & d waste processing facilities In case of any accident during construction and demolition waste processing or treatment or disposal facility, the officer in charge of the facility in the local authority or the operator of the facility shall report of the accident in Form-V to the local authority. Local body shall review and issue instruction if any, to the incharge of the facility.
