  Introduction • Construction andDemolition (C&D) waste refers to materials produced during construction, renovation, and demolition. • Management is essential to reduce environmental impact. • C&D waste forms a significant part of global solid waste.
• 3.
  Sources of C&DWaste • Construction activities: new buildings, roads, bridges • Demolition: old structures, infrastructure • Renovation: residential and commercial modifications • Maintenance: ongoing repairs • Examples: concrete, wood, metal, bricks, glass, plastics
• 4.
  Environmental Impact • Landfillspace consumption • Soil and groundwater contamination • Dust and air pollution • Depletion of natural resources
• 5.
  Objectives of WasteManagement • Reduce waste generation • Maximize reuse and recycling • Protect the environment • Promote sustainable development
• 6.
  Waste Management Hierarchy •Reduce • Reuse • Recycle • Recover • Dispose Emphasis on minimizing waste at the source.
• 7.
  Strategies for C&DWaste Management • Pre-construction planning • Material audits and inventories • Selective demolition (Deconstruction) • Use of sustainable and recyclable materials
• 8.
  Recycling and Reuseof Materials • Concrete: crushed and reused as aggregate • Wood: repurposed for furniture or bioenergy • Metal: melted and recast • Bricks: cleaned and reused in new constructions
• 9.
  Technologies in Waste Management •On-site and off-site recycling • Mobile crushers • Waste tracking apps and software • Automated sorting equipment
• 10.
  Challenges in ManagingC&D Waste • Lack of public and industry awareness • High initial costs for recycling setups • Insufficient regulatory enforcement • Technical difficulties in material separation
• 11.
  Government Policies and Regulations •Construction and Demolition Waste Management Rules (2016) - India • International standards (e.g., EU Waste Framework Directive) • Incentives for green construction and recycling
• 12.
  Case Studies • Majorcity project reused 70% of demolition materials • Sustainable demolition project saved 60% cost in waste disposal
• 13.
  Future of C&DWaste Management • Adoption of smart construction practices • Increase in green building certifications (e.g., LEED) • Innovation in recycling technologies and materials
• 14.
  Conclusion • C&D wastemanagement is crucial for sustainability. • Cooperation among governments, industries, and individuals is essential. • Move towards a greener, cleaner construction industry.
