Every demolition job produces a pile, and what happens to that pile says a lot about the contractor. Debris planning is one of the less visible demolition processes, but it affects cost, schedule, neighbours and how much ends up in landfill. In a city as dense as Toronto, it’s also a logistics puzzle.
A typical interior strip-out produces drywall, steel studs, ceiling tile, carpet, wood, wiring and packaging. A house demolition adds brick, concrete, roofing, framing lumber and soil. Some of it recycles well. Metal has scrap value, and clean concrete and brick can be crushed into aggregate. Drywall, clean wood and cardboard can often be diverted too, depending on the receiving facility.
There are two broad approaches. Source separation means sorting material into separate bins as it comes out. Mixed loads go to a transfer station that sorts them afterwards. Source separation takes more space and discipline, but it usually gives better diversion and lower disposal costs. On a tight downtown site, it may only work for one or two main streams, like metal and concrete.
Whichever approach you take, sorting works best when it’s planned as one of the core demolition processes rather than an afterthought. Decide the streams before the first bag is filled, label the bins and tell the crew which materials go where. A contaminated bin is hard to fix later.
Ontario sets specific requirements for large demolition projects. Under Ontario Regulation 102/94, anyone demolishing one or more buildings with a total floor area of at least 2,000 square metres must carry out a waste audit, write a waste reduction work plan and put that plan into action. Both documents have to be ready before demolition begins, and the plan, or a summary of it, must be posted where workers will see it. A companion rule, Ontario Regulation 103/94, requires a source separation program on those same projects.
Smaller jobs fall outside those rules, but the same habits still make sense.
In a tower, debris leaves through the freight elevator and loading dock, on the building’s schedule. Carts have to fit the elevator, loads have to respect weight limits and corridors need protection along the way. Book those elevator slots well ahead. At street level, a bin on a City road or sidewalk generally needs a street occupation permit, and where it sits affects pedestrians, cyclists and traffic.
For houses, the bin usually goes on the driveway. Homeowners demolishing a house can also temporarily opt out of City garbage and recycling collection while work is under way.
Before demolition starts, it’s worth asking what could be reused. Doors, hardware, light fixtures, cabinetry, stone and some architectural details can have real value. Salvage takes longer than straight removal, so decide early and write it into the scope rather than asking the crew mid-job.
