Construction and demolition waste

Give Waste a New Life

The City defines construction and demolition waste as non-hazardous, non-contaminated solid waste resulting from construction, remodelling, repair or demolition projects. Construction and demolition waste may include:

  • Bricks, concrete, rock and other masonry materials
  • Wood
  • Scrap metal
  • Drywall
  • Plumbing fixtures and piping
  • Roofing shingles and other roof coverings
  • Reclaimed asphalt pavement
  • Glass, porcelain, ceramics

Guelph residents are encouraged to reuse and recycle construction and demolition waste, whenever possible.


Remove materials such as architectural features, fixtures, cabinets, doors, windows and wood flooring from a building prior to demolition. These materials may be reused in another project or consider repurposing materials through the Waste Wizard.


Can’t reuse these materials? Bring them to the Waste Resource Innovation Centre for recycling. Recycling materials gives them new life. Recycling involves the collection and processing of certain materials to become new products (e.g. metal, glass, bricks).

Tips to divert construction and demolition waste from landfill

  1. Be creative. Think of ways to reuse construction and demolition waste waste. Consider reusing materials from an old building in a new building on the same site.
  2. Plan ahead. It’s important to estimate the quantity and type of materials that will be generated during construction. Consider repurposing materials through the Waste Wizard.
  3. Consider recycling materials that can’t be reused. Recyclable materials include clean wood, metals, gypsum drywall and cardboard/paper.
  4. Sort it out. Sort and bring construction and demolition waste to the Waste Resource Innovation Centre or choose a waste and recycling service provider, if needed.
