Construction waste needs to be reused, say experts
With a spurt in urbanisation, cities
are facing serious environmental consequences due to construction and
demolition waste which needs to be recycled and reused, experts said here
At a seminar "Waste to
Resource", experts pointed out ways and means to reuse construction
material to build buildings which are sustainable.
"India needs urgent intervention
to protect its land, water, public space and environment from the egregious
construction expected to explode with the urban boom," said Sunita Narain,
director general of the Centre for Science and Environment (CSE).
"The country is running out of
natural sand, which is used in construction, but we have to keep on with our
building activity and for that a very good option would be using construction
and demolition waste material," Narain said.
Surya Kakani, an architect from
Ahmedabad, who has built buildings using rubble, fly ash and broken bricks,
said: "If we can identify small areas in cities where rubble can be
recycled, it would save time and energy and make such recycled products
N.B. Mazumdar, chief technical
advisor, IL and FS Environment Infrastructure and Services, a leading company
in the waste-management sector, said: "Standards (for building) should be
changed with time as new building norms are coming up."
Listing steps needed for ensuring
quick recycling of building material, the CSE said the first and foremost need
was for a change in rules of municipal bodies to push for optimised use of
building space and materials and waste prevention.
It also favoured tax policies for
waste generation and reuse to minimise waste and prevent unsafe disposal.
