Deconstructing Vancouver’s Green Demolition Bylaw

Home owners and property developers in the city of Vancouver will follow new demolition waste recycling requirements for houses built before 1940 thanks to the Green Demolition Bylaw which went into effect on September 1, 2014. From now on, a minimum of 75% of the demolition waste from these older homes will be recycled; and that number increases to 90% for character houses from the same era.

We had the opportunity to interview Senior Sustainability Specialist Hugo Haley from the City of Vancouver to find out more about the Green Demolition Bylaw and what it means for home owners and developers. Here’s what he was able to share with us:

Q:  What led the City of Vancouver to establish these new recycling requirements for pre-1940’s houses?

Traditional demolition sends tonnes of waste to our landfills.

A: Metro Vancouver’s regional solid waste plan requires all municipalities to do more to encourage recycling of construction and demolition waste. Also, the City of Vancouver’s Greenest City Action Plan’s Zero Waste goal is to reduce the amount of solid waste disposed to landfill by 50% by 2020. To achieve this goal, the City intends to improve demolition waste recycling performance, and put in place policies to achieve 50,000 tonnes additional recycling from the demolition and construction waste sector.

Q: What is the difference between a pre-1940’s home to one that was built later that prompted this policy? Will newer home demolitions become subject to similar recycling requirements in the future?

A: Homes built before 1940 often have valuable architectural features … built with old growth timber and other valuable materials. The City would like to discourage older character homes from being demolished … if they are going to be demolished, the City wants to ensure that a high percentage of demolition materials are reused or recycled. In the future, the City would like to include recycling requirements for all ages classes of homes to make sure valuable and usable materials are kept out of the landfill.

Q: What is “deconstruction” and why is it being used to demolish these older homes?

A: Deconstruction is an alternative to traditional demolition. Deconstruction is a more systematic and careful approach to taking apart the house where more of the materials are kept intact and can then be separated for reuse and recycling.

Deconstruction techniques allow higher recycling rates.

Q: Is this new bylaw unique in Metro Vancouver, perhaps even in North America?

A: These requirements are not unique in North America. There are numerous municipalities in the United States that require demolition waste recycling, with California’s requirements applying state wide. Cities with similar policies include Chicago, Seattle, San Fransicso and Boulder. In Metro Vancouver, the city of Port Moody has such a policy.

Q: Do you have any relevant statistics you can share including how many demolitions and how much material you think will be diverted from the landfill each year?

A: There are about 1,000 homes demolished in the city of Vancouver every year. About 350 of those are from the pre-1940 era and subject to the new requirements. We expect about 12,000 tonnes of additional reuse and recycling to be achieved in the first year … This amount will increase as the requirements extend to more homes.

Green Coast Rubbish President & CEO Eamonn Duignan wrote a letter to Council in support of the new bylaw saying “we whole heartily support this policy initiative … far too often we see reusable or recyclable material landfilled, simply because there is no regulatory framework in place.”
