Environmental problems have been considered as a serious situation in construction. Waste management is pressing harder with the alarming signal warning the industry. Reuse, recycling and reducing the wastes are considered as the only methods to recover the wastes generated, Many construction waste materials can also be recycled like wood, drywall, cardboard, metals,plastics, etc., what methods we can implement in a cost effective way for waste recycling. I want more and more ideas and thoughts from you................

Usage of Flyash based, slag based cement contributes to cost - effective  waste recycling.

Wood

idea posted by Pradeep Khanna Construction-Heavy, DLF
I could say wood will account for 40-50% of the construction waste stream, it can be used in composting operations, animal bedding, landfill cover, some building products, and as an industrial fuel source. For many of these applications, however, there is concern with regard to the adhesive content of engineered wood products such as plywood, oriented strand board, or wood I-beams. Up to half of job site wood waste can be engineered wood product waste.This is a good example of how a local forum would be helpful in identifying recycling obstacles and opportunities.

yes pradeep scrap wood and drywall have low market value. You will generally not find outlets willing to pay for these materials, but you may find outlets that charge less per ton or cubic yard than landtills. The best markets for scrap wood tend to be as a fuel for power generation and as an ingredient for mulching and compost. Recycling drywall into new wallboard is something many gypsum manufacturers are working on over the long term.

A few suggestions

idea posted by KALIYAMOORTHY Oil & Gas Area Coordinator, Undisclosed
  • Waste papers can be used to make toys, statues, baskets etc as part of Handicraft art. Baskets made out of paper pulp is very durable & its simple too.
  • Waste plastics can be recycle as PVC.
  • Food waste can be used for producing biogas.
  • Degradable waste can be used for compost (manure).
  • Tyres can be chipped & recycled(its a small industry business).
  • Used batteries returned to supplier for their disposal.
  • Used oil can be used for Concrete works, cleaning purposes.
  • Items that are not recyclable, is to be disposed of by Landfill.
  • Waster water treatment plant for treating waste water.
  • Waste plastic treatment plant for treating plastics(burning plastics at higher temperature yield gas that can be used).
  • Incineration is also a technique but not advisable because it is against Global warming. But the heat so produced can be used domestically / industrially.

Metals and Vinyl

idea posted by Abhik Datta Construction-Heavy, Sobha Developers
I think Metals and vinyl have good market value but the small amounts generated per job make cost-effective recycling more difficult. Some type of stockpiling or backhauling to a supplier by the subcontractors generating the metal or plastic waste can work.....

Carboard

idea posted by Anjali Sinha Construction-Heavy, Sobha Developers
I think carboard's market value is better than that for wood and drywall but highly variable. Cardboard recycling is widespread, outlets are usually easy to find. This is a good material to keep out of your dumpster, particularly if you pay by volume

"Construction and demolition debris needs proper disposal & use of recycled Material"

idea posted by Brajesh Mishra Construction / Contract Management, UPSSCL
Such waste requires focus primarily in view of its potential to save natural resources, the space it occupies at the sanitary landfill site and its potential for spoiling processing of biodegradable as well as other recyclable waste. On the other hand, it has potential use after processing and grading. So far in India there is very little effort to manage and utilise construction and demolition waste. Each city needs to have its own mechanism for collection and disposal of waste from bulk waste producers and construction debris. It would be necessary to evolve a system in which the generator of the such waste, whether small or large, pays for appropriate disposal. Not much effort has been made in this sector.
