The Challenge:

Vancouver is Canada's 3rd largest metropolitan region, with an estimated population base of 2.5 million people. It operates the 3rd largest Port in North America and is a significant infrastructure owner as it manages approximately $25 billion of capital assets encompassing facilities, parks, streets, and underground infrastructure. Since 2011, the City has adopted a service-based capital planning framework to drive accountability, increase transparency, and enhance a holistic, city-wide approach to long-term capital investment decision-making.

It is estimated that the Greater Vancouver Regional District (GVRD) and its residents, businesses, and institutions generated about 1,247,500 tonnes of garbage in 2021-2022. The GVRD has improved its recycling rate in the last few years, from about 40 percent in 1995 to over 60 percent in 2018. Concrete, yard, and food waste (organics) are some of the most recycled materials in the metro region.

Key Facts & Figures

  • Approximately 2.6 million tonnes of municipal solid waste was disposed of in B.C. in 2020. While there has been a decreasing trend in municipal solid waste disposal rates since the 1990s, much of the garbage disposed of could be reduced (by not being generated in the first place), repurposed, composted, or recycled.
  • Waste reduction efforts have become increasingly important as the B.C. population continues to increase, landfills approach their capacity for receiving new waste, and the imperative to reduce greenhouse gas emissions from waste disposal grows.
  • Tracking waste disposal across B.C. is essential as it provides historical trend information and the current status of waste disposal, which inform and guide efforts to reduce the waste we create.
  • In 2020, British Columbians disposed of an average of 499 kg of municipal solid waste per person, down 70 kilograms per person since 2012, though higher than the low of 473 kg/person in 2016.
  • Provincial initiatives supporting decreased waste disposal rates include the CleanBC Plastics Action Plan, organics diversion, food waste prevention, extended producer responsibility (recycling) programs, and organics infrastructure and collection funding.
  • Variability in disposal rates from one region to the next is influenced by factors such as population density, economic activity, tourist and transient population fluctuations, distance to recycling markets, the role of various stewardship agencies operating in an area, and the capacity and infrastructure in place in a region. While disposal rate data do not tell the whole story, they help set the stage for continuous improvement in waste management in B.C.

The Solution:

Sustainability has played a significant role in managing municipal solid waste within the GVRD. This region is one of the first in Canada to consider creating energy from waste using an integrated solid waste management system. Since its opening in 1988, Metro Vancouver’s Waste-to-Energy Facility (WTEF) has played an essential role in the region’s solid waste management system.

Metro Vancouver owns the energy from the waste facility, which, when built, was initially operated and maintained by a subsidiary of Veolia ES; the facility is now operated and maintained by Covanta Burnaby Renewable Energy Inc. The facility ensures that garbage is managed environmentally and generates renewable and valuable energy sources such as steam and electricity. The Waste-to-Energy Facility (WTEF) is located in the commercial and industrial areas of south Burnaby. It receives waste from Burnaby, New Westminster, and the North Shore of Vancouver and is responsible for the environmentally safe disposal of over 20 percent of the region’s waste.

In 2003, the GVRD installed a turbo generator that uses steam to produce electricity and then sells it to BC Hydro. In 2006, a $7 million upgrade was completed to increase the heat recovered from the waste and the amount of electricity produced. The revenue from steam and electrical sales offset the operational costs of the solid waste management system. Strict environmental monitoring confirms that the WTEF is one of the cleanest facilities of its kind. The Solid Waste Association of North America (SWANA) recognizes it as one of the best facilities on the continent. In 2003, the Association of Professional Engineers and Geoscientists of B.C. (APEGBC) presented its first Sustainability Award to the GVRD, partly for installing the turbo generator.

In 2018, Metro Vancouver introduced technological improvements to increase metal recovery at the Waste-to-Energy Facility. An eddy current separator was installed to separate non-ferrous metals such as copper and aluminum from bottom ash, and a second magnetic separator increased the recovery of ferrous metals.

The Outcome:

The site was initially established in 1985 to utilize steam through sales to a paper recycler, and the site's central location was selected because it minimized the distance of hauling waste, resulting in further benefits for the facility. This was designed with future potential in mind for eco-efficiency. Commercial operation started in 1988, using a state-of-the-art combustion and air pollution control system. Over 50% of the facility equipment is dedicated to air pollution control. This waste-to-energy facility has three processing lines, each processing about 11 tonnes of garbage every hour. Since its start-up, it has processed more than 5 million tonnes of municipal solid waste.

Throughout its 30+ years in service, each year, the WTEF turns, on average, 250,000 tonnes of garbage and trash into 900,000 tonnes of steam and 132 GWh of electricity, providing both economic and environmental benefits to the region. A portion of this steam was initially sold to North Pacific Paper Company (NORPAC), a paper recycling facility, helping eliminate the use of fossil fuels. Air emissions produced from the facility are a small percentage of the total air emissions in Metro Vancouver. The facility operates under continuous air emissions monitoring within all regulated limits.

The electricity sold to BC Hydro is enough to power 16,000 homes and recovers about 7,000 tonnes of metal annually. The Solid Waste Association of North America (SWANA) recognizes it as one of the best facilities on the continent. The benefits of a Waste-to-Energy plant like the Burnaby facility are that it can be located in densely populated metropolitan areas as a highly responsible local disposal solution for waste that cannot be recycled. Metro Vancouver annually earns approximately $8 million from the sale of electricity and $300,000 from the sale of recycled metal to a company that produces reinforcing steel.

Strict control over combustion conditions, such as temperature and airflow, minimizes the amount of emissions released. State-of-the-art environmental protection technology treats air emissions continuously, monitoring them and regulating them under provincial legislation. Monthly reports are submitted to the Provincial Ministry of Environment, the City of Burnaby, and the Fraser Health Authority. Independent stack tests are performed on each processing line three times a year to test for acid gases, total hydrocarbons, metals, and particulate matter. The Lower Fraser Valley Air Quality Monitoring Network continuously monitors the ambient air environment at 30 sites throughout the Lower Mainland. No measurable impact has ever been found from the energy-from-waste facility.

The BC Minister of Environment approves the facility through an Operational Certificate, which sets requirements related to its operation, including emissions limits, monitoring, reporting, and publication. Strict environmental tracking confirms that the WTE facility is one of the cleanest facilities of its kind.

The WTEF has zero liquid discharges (excluding washrooms) to the sewer system. This means reduced impacts on the environment by minimizing water use and lowering demand on the sewer system. The WTEF is certified by the International Standard Organization (ISO) 14001. This is an international environmental management protocol to ensure regulatory compliance, ongoing monitoring, and continual improvements. Additional key attributes are:

  • 1 Tonne of waste processed by the facility reduces lifecycle emissions by 0.7 tonnes of net CO2e compared to landfilling;
  • In 2020, the facility avoided emissions equivalent to 35 thousand passenger vehicles driven for 1 Year period, or burning 82 million kgs of coal;
  • The facility operates up to 98% below Operational Certificate Limits and
  • 32,678 garbage trucks diverted from landfill.

Summary of the 2018 operation costs:

  • The cost to operate the facility was $20,497,223
  • Disposing of the fly ash was $1,385,142
  • Electrical energy sales $5,584,341 
  • A total for municipal solid waste disposal of $58.16 per metric tonne (2,204 pounds).
