8 Oct 05:

The 49 page MCGM Construction and Demolition and De-Silting Waste (Management and Disposal) Guidelines - September 2005 are in the Cleanliness Section in . The direct link is
Suggestions have been received by the NGO Council from Bejoy Davis, Almitra Patel, and Kisan Mehta. These along with those recommended by the NGO Council Cleanliness Group in the Policy Framework Guidelines are given below as recommendations to MCGM to incorporate in the Guidelines.
Overall comment: The document developed is a good document for category -1 and category -2 waste generators and will at least regulate the disposal of debris, but not for waste generators of housing societies and offices some more control mechanism still needs to be developed.
1. PART E: Point 22, Role of MCGM     page 14 of 49.

Even after the waiver is approved the EE (Env.) of that Zone should have to put on record where the disposal took place and the waiver should not include the waste generator using their own vehicles to cart the C&D waste.

2. Point 70, Dial-up Services            page 29 of 49

The token amount of fees is not mentioned. It should be specified and should be linked to quantity by volume.
The document also needs to add a component of the penalties to be charged to the individuals who would not pay the operators to pick the waste created due to remodeling, renovation, repairs.
The document doesn't mention much about the specific issues of collection in Slums. The collection can't be general and same for the societies and slums because paying for disposal C&D waste is going to be difficult. Non payment will end up in the waste lying in the open areas and roads which even the licensed operators are not going to pick up as the economics doesn't work. How will this be monitored?
A suggestion is to have a bin for debris collection in the areas where Datak vasti Yogana is in place so that it could be
monitored by the responsible CBO.
3. Annexure 1: Designated Disposal Sites                               Page 30 of  49

The designated disposal sites viz. Hariyali village and Dahisar/Gorai seem to come under no-development zone and Coastal regulation Zones where under the regulations it clearly mentions no dumping of debris is allowed. As per high court notification, even dumping at Gorai has been discontinued, so how can it be restarted? It is also not clear which part of Hariyali village and which part of Dahisar/ Gorai are contemplated.
The disposal technique seems to be only dumping in low lying areas which is not sustainable in the long run as not many low lying areas are left in Mumbai. A suggestion is to look into the disposal option in much broader way of creating more space at the disposal locations by ensuring that the dumped waste is recycled. Recycling Operators could recycle the C& D
waste at the disposal sites which will help to create more space for future wastes and disposal sites never get exhausted. Options are available for recycling.

The system mentioned in the document will only run if the end disposal is managed properly otherwise the EE (Env) will find it difficult to search for new spaces for disposal.
A suggestion is to create a small hill in the Mulund disposal site where only C&D debris & silt to be put. This will enable 25 years of C&D waste disposal to be undertaken. Ultimately, this should be landscaped with grass, garden, trees, etc. and be converted into a picnic spot.
A suggestion is that since Kanjur Marg is a low lying marshy area, it will need to be raised at least 2-3 meters above highwater mark to comply with landfill conditions.  This can be an opportunity for disposal of clear debris to raise the level sufficiently for accepting municipal waste.
4. Annexure -8: Specifications of typical containers to be used for storing C & D waste     page 38 of 49

Please consider the possibility of designating a special color for all the vehicles carrying C&D waste so it becomes very easy to differentiate. This will also help citizens to quickly identify illegal waste dumpers, if any.

5. Permissions should be needed:
The system will work only if permissions are needed to be got from MCGM but as per the section 342 the housing societies need not get any permissions for their repairs then what is the control mechanism by MCGM? Similarly for Shops and Establishments.
6. Segregating C&D waste from earth :
The guidelines needs to  ensure that the waste from construction site and building repairs are not mixed with earth as that renders the debris totally improper to use for recycling and will just add to the load on the disposal sites.

7. Salvaging & Recycling of Debris: 
MMRDA's  MUIP has a unique feature ,the rocks excavated from the widening of roads are taken to a site which breaks it down into aggregates . These aggregates are then used in the subgrade of the new  roads  which are done. The site where the stone crusher plant has been set up is next to the highway between Kandivali and Borivali close to Thakur complex well in the vicinity of the residential area. A suggestion is to have these kind of crushers at the disposal sites for large quantity recycling, these disposal sites if equipped with these crushers then the salvaging of debris is possible and will be sustainable and also provide a long term solution for the MCGM.

Tenders could be floated for the conversion of debris to private bodies  who could  work out all the possible ways to market their products. MCGM should formulate a clause in all the tenders that all their contractors should use more and more environment friendly and recycled materials this will also ensure the success of the debris disposal plans. All the machinery is
available in the Indian Market right from crushers to interlocking pavers making hydraulic machines.
MCGM road specifications should be mandated to favour specified recycled aggregate for laying subgrade e.g. tiles, marble, are ok; bricks and plaster are not.

If  a developer wishes to salvage the waste produced in situ, then smaller machines ( e.g. CIDCO -YUVA plant models ) are available which could convert the waste to useful products like bricks and interlocking pavers. The machines will stay till the time the construction is over then the machine could be moved to another location this will ensure that no constant plant is operational and any nuisance is created to the residents in that vicinity.
A pilot project should be worked out and the location could be the defunct pelletisation plant situated very close to the Deonar dumping ground which is a MCGM property as there are sheds which are already built for the pelletisation machinery. The other location for pilot plant could be Gorai dumping ground.

Depending on the change of the nature of debris ten years from now as there are going to be more and more cessed buildings the concrete recycling is a must e.g. in Toronto.
Recycling technologies should be explored.
8. Solutions: for disposal of silt

Silt should be disposed / utilised as landfill cover for garbage or compost rejects. Vegetation should grow well on drain silt. Drain silt should never be transported along with 'kooda' in the same vehicle as this makes composting impossible at the waste-processing and disposal point.

9. Collection of construction and demolition waste

From Report of the Supreme Court Committee on 'Solid Waste Management in class 1 cities in India, 1999'
To facilitate the collection of small quantities of construction and demolition waste generated in the city, suitable debris banks to be created in, say 25 (ward-wise), different areas throughout the city;  and notified people to deposit small quantities of construction and demolition waste. Containers could be provided at such locations and small collection charge levied for receiving such waste at such sites and for its onward transportation. Rates may be prescribed for such collection by the local body. Contracts could be given for managing such sites.
YUVA / NGO Council is willing to identify such sites along with BMC officials.
Generally speaking, the locations where C&D waste is being illegally thrown currently are usually suitable locations to be used as local debris banks, so these should be explored first. Mangrove areas, water bodies, etc. are naturally to be not considered.

It is one of the beautiful compensations of this life that no one can sincerely try to help another without helping himself. --Charles Dudley Warner
