Best practice strategies to reduce the waste produced during construction, refurbishment and demolition of buildings include:
Designing for material optimization:
- Design flexible spaces to serve multiple functions
- Optimize structural systems and reduce number of finish materials.
- Reversible attachments allow disassembly of materials and components at the end of their useful life.
- Coordinate dimensions and standardize similar elements to encourage repeatability to avoid scrap.
- Provide material information in BIM model
- Consider providing furnishings and fixtures as a service so they can be maintained, upgraded and taken back by supplier at end of useful life.
Selecting Materials for Circularity
- Reclaimed and reused buildings, materials and components
- Specifying materials with recycled content.
Waste Management Planning On-site
- Ensuring that procedures on the construction site facilitate waste segregation and recycling.
Planning for reduced C&D waste must happen at a project’s start and be part of an integrated design approach. For more strategies and considerations per phase, see Zero Waste Design Guidelines Best Practice Strategies for Construction and Demolition Waste.
