A brief description of programs, policies, infrastructure investments, outreach efforts, and/or other factors that contributed to the diversion rate for construction and demolition waste:

For LEED projects, recycling construction and demolition debris is a priority and Columbia has had success with rates as high as 84% for LEED construction recycling. Operations manages all recycling for small projects. General contractor hired for medium projects (pay lump sum so don’t track and don’t divulge hauler info or recycling). Struggle for 0-10,000 GSF projects. Regardless of the size of project sustainability practices are followed when pursuing LEED certification or following LEED guidelines for new projects with a minimum of 50% for one credit and 75% for second credit recycling.

Apartment renovations are minimized as the majority are historic buildings. Renovations that are made reuse the infrastructure-walls, ceilings, flooring except when it’s not structurally possible or for health and safety reasons. For instance if a floor is replaced it’s because the floor is usually rotted out and it’s over 100 years old.
