OP-24: Construction and Demolition Waste Diversion

Construction and Demolition(C&D) waste comes from four key sources: minor renovations, workshops, new building demolition and construction, and major renovations. Contractors are responsible for diverting material from the landfill for major renovations and new construction. In the last four years, the university has opened on average a new building per year. Dalhousie has a green building policy that supports LEED gold certification or higher. C&D waste diversion is targeted to reach high levels of diversion. For the last four buildings built between 2010-2014, 80-93% of C&D waste was diverted from the landfill. The local municipality also has a minimum C&D bylaw for 75% diversion from the landfill.

The period of comparison used in the STARS calculations is for 2013-2014. It includes tonnage from internal projects and workshops as major renovations and new construction is managed by external contractors but must meet Dalhousie and Halifax diversion goals. This comparison includes tonnage from the main C&D bins on campus where C&D is brought for recycling from internal renovations and workshops. The directive is all C&D should be brought back to the dumpster for recycling. It is hard to determine what is the total C&D tonnage exactly for materials brought back to the C&D bin as the remainder would be included in general dumpsters on campus. However, the hauler and landfill monitor C&D in dumpster loads to meet the 75% diversion rate and mixed loads of C&D and garbage are rejected at the landfill. Given this, we are anticipating at least an 80% diversion rate on the conservative side
