Recycling matters
Recycling concrete waste helps reduce the negative
environmental impacts of construction activities.
“In India, concrete recycling rates and available
applications of recycled concrete vary largely, but
they also offer useful strategies for government and
industry to work together for expediting the concrete
recycling progress,” adds Kumar.
Concrete recycling is known to everyone majorly but
not adopted very often by the customers. According
to our view, if the customer is getting some of their
volume base structure demolished, and if this is being
done at one or multiple construction sites, then
the customer should opt for debris recycling of the
structure to be demolished. This is because the client
can use the recycled debris in their other construction
site locations at the areas for finishing, road making
and non load bearing locations which will allow them
to save cost by reducing the cost of concrete purchase
for the respective work replaced with debris recycling.
Precious recycling concrete is wasted due to not being
used wisely in recycling. Back filling work, paver blocks
or roads can be made out of the material recovered
from demolition.
“Annually, India produces around 10 to 12 million tonnes
of construction, demolition, and excavation waste and
this waste is either disposed in illegally in non-engineered
landfills, rivers or water bodies,” says Guizzetti.
Guizzetti further adds, “The Ministry of Urban
Development has directed states to setup a Construction
and Demolition (C&D) waste facility in all the cities with
a population of more than 1 million. But unfortunately,
only few such facilities are presently working in India
and most of the C&D waste ends up in the ridge areas
considering the amount of infrastructure development
which is at its peak.”
Challenges in recycling
Demolition, processing and the recycling of the resulting
materials are often analysed separately. High quality
recycling of concrete waste does not always correspond
to production or use of the product with the highest
value, rather to the most feasible product in a specific
project or region. “It is by analysing the whole disposal
or supply-chain, including the substituted material, that
the best effects of recycling can be achieved. Issues
regarding the handling of polluted materials should be
discussed from a practical point of view,” adds Kumar.
Moreover, some aspects to consider regarding future
demolition when producing new concrete products are
presented.
The challenge for growth is to provide timely delivery
of volume base quantity with respect to cost. Need for
recycling in the other projects by client is of foremost
importance. “The Government should make a law to
make use of recyclable concrete material in their projects
and compulsory use of it in different manufacturing
industries - the common dumping yard for all the
demolition debris disposal material. This will help the
industry and environment and control the cost in every
way,” adds Gandhi.
Need to heed
There are challenges in recycling of demolition waste
so there is need to have greater supervision and actual
penalties should be imposed on those who violate
government directives and policies. The growth of
construction is very high; hence the recycling market
needs to grow at an even greater speed to catch up.
Today, most of the demolition waste is disposed of
by dumping it in the landfills. This is causing a huge
shortage of dumping places in the already choked urban
areas. With limited number of C&D facilities currently
in operation, and shortage of dumping places in the
urban areas, recycling becomes imperative. There needs
to be greater incentivisation on the demand and better
control on adherence of these new policies which have
actually been put in place by the Government. n
Always do a final sweep before
the demolition process begins.
It is absolutely recommended
to go into each and every room,
including closets, bathrooms
and hallways, to ensure that
everyone and everything is out
of the building.
