Based on an efficient Construction and Demolition Waste (CDW) management it's possible to minimize the irregular deposition of these residues and also to increase their recycling and reuse as material for civil construction. However, there are several aspects that can be used in CDW management. The development of a CDW management model will assist municipalities in adopting actions that bring economic, environmental and social benefits.
Using success cases from some cities makes it possible to understand some aspects that optimized the CDW management in those places. The challenge is to create a model that has broader applicability. In this research, two tools will be used: Multicriteria Decision Analysis (MCDA - AHP) and Geographic Information System (GIS).
At this point, it is necessary to raise (your help is fundamental) the aspects that are relevant in the CDW Management. Thanks for support!
Dear Rafael,
I'm currently engaged with the same challenge in my hometown, Isfahan. Here, the problem is to provide an integrated CDW management plan to allow managers to track it from the very beginning (generation) to very end (final disposal). We did the following process. That might be hint for you as well:
- A wide literature review and studying experiences of other similar cities
- Doing a broad study regarding the current situation (statistics, dumping site conditions, illegal procedures, current key players, etc).
- Developing a modified process in Isfahan Municipality
- Developing a system to help managers monitor the process
-Approval of required bills in city council
- Running a pilot in selected regions of the city
- Organizing the dumping site
Considering the market situation for recycled aggregate products
- Enforcing regulations for using recycled aggregates in constructions where applicable
- Preparing the situation for establishing a CDW recycling plant (especially concrete wastes to recycled aggregates).
I hope this could be useful for you.
Dear Ali Ferdowsi,
Thank you very much for your support. I think that Isfahan's challenge is the same problem that we have in Brazil cities. Good luck with CDW challenge and thanks for answer.
Dear Pankaj Kumar ,
Thanks for answer! The transportation causes much impacts in CDW management.
