Low-carbon concrete project completed at Calgary International Airport

29 January 2020

The new de-icing pad will reduce emissions at the airport by
160 tonnes a year; equivalent to 209 acres of forest absorbing carbon in the
same time frame.

Calgary International Airport (YYC) has announced the completion of its new high-tech,
low-carbon concrete de-icing pad installation, the East Deicing Apron.

Following construction during August and September 2019, the
first aircraft have now begun to utilise the facility.

The East Deicing Apron has been built with reduced-carbon concrete, provided by CarbonCure, and represents the largest quantity of the specialist concrete to ever be used at a Canadian airport.

Carmelle Hunka, Vice President of the General Counsel for
Risk and Compliance at the Calgary Airport Authority, said: “YYC Calgary
International Airport is pleased to be a leader as the largest airport user to
date of CarbonCure in Canada. As YYC strives to be a leader in airport
sustainability, we fully supported our airline partners in the decision to
inject captured carbon into the new East Deicing Apron’s concrete pavement.”

Waste CO2 captured by industrial gas
suppliers is injected into concrete during mixing, enabling the production of
stronger, more sustainable concrete. Every cubic metre of concrete made reduces
an average of 16kg of carbon emissions – an average high-rise built with
reduced-carbon concrete would save approximately 120 tonnes of CO2.

An estimated 25,000m3 of reduced-carbon concrete was used for the construction of the East Deicing Apron, representing 160 tonnes of reduced carbon emissions; equivalent to 209 acres of forest absorbing CO2 over the course of a year.
