CONSTRUCTION WASTE GENERATION….
Central Pollution Control Board has estimated current quantum of solid waste generation in India to the tune of 48 million tons per annum of which waste from Construction Industry accounts for 25%. Management of such high quantum of waste puts enormous pressure on solid waste management system.

REDUCE….REUSE….RECYCLE
• REDUCE – Debris Generation on site
• REUSE – Debris generated on-site / Use salvaged M aterials
• RECYCLE – Use Materials with a Recycled Content

Approach to Resource Reuse involves:
• Separation of Debris at source
• Preparation of separated fractions for reuse
• Reuse on site
• Reprocessing and remanufacturing
APPROACH TO RESOURSE RECOVERY- SEGREGATION OF DEBRIS

WOOD – A SUSTAINABLE MATERIAL?
Wood has a Wide spread use in Construction
Certified Wood
• Environmental
– Reduces impact on forestry
• Destruction of forest, loss of wildlife
habitat,
• Wood – sustainable resource
– Renewable, biodegradable, non-toxic,
energy efficient & recyclable
• Community
– Responsive forest management

Conclusions…….
RESOURCE REUSE
• Segregate debris at source
• Reuse debris generated on site within the site
• Find Creative ways to Reuse salvaged Materials
• Encourage the Use of Local Materials
• Specify Materials with a Recycled content
• Careful and Educated use of Wood
