Report by Priyabrata Nayak, New Delhi: Waste materials sourced from construction and demolition is posing threat in a larger way to the cities especially metros. Cities are chocking with the pile of wastes which is causing serious threats to our environment. Stakeholders from the urban development sector have urged the government to find-out an immediate solution in terms of recycle these waste materials and minimize the its generation. This was said at a seminar “Waste to Resource: Addressing Construction and Demolition Waste in Cities” jointly organized by advocacy group Centre for Science and Environment (SCE) and Environment Pollution Control Authority (EPCA) at India Habitat Centre here.
Sunita Narain, Director General of SCE said keeping pace with the fast expansion of the cities, demolition and construction are also soaring, resulting in the outburst of the solid waste. This is matter of concern as we would be confronted with a situation related to the scarcity of dumping yards in the outskirts.
“Prior to the situation gone worst, the authority need to amend existing Municipal Solid Waste Management Rule for effective handling and management of C&D waste as well as the master plans for the cities to be revised, which will provide us well managed waste treatment plants. These plants will be able to collect, store and recycle the construction and demolition (C&D),” said Ms Narain.
“Due to the C&D, rivers are being dug enormously for the procurement of sand and waste materials being dumped there, which is causing a serious threat to our eco-system. The treatment plant will be helpful for the reuse of the sand after proper segregation,” Ms Narain added.
Stressing upon the minimum use of natural resources Bhure Lal, Chairman, Environment Pollution Control Authority (EPCA) said everybody related to urban development should realize that the availability of resources is limited.
“We should concern about the hazards of the rampant construction and demolition. The stakeholders must be responsible for the protection of our ecology and environment. The need of the hour is to put strict guidelines for the use of natural resources and their use,” said Lal.
Sunil Soni, Director General, Bureau of Indian Standars said C&D waste should be looked as an opportunity. “BIS is not in favor of ban or obstructing the recycling of C&D waste. We only want to ensure quality product for the reuse in construction.
Pointing out the use of recycle products Surya Kakani, an architect from Ahemedabad said we can minimize the hazards by using fly ash, recycled sand, broken bricks at the construction. We can also come up with the treatment plant inside the city by using the abandoned land.
