Progressive Planet marks first successful pour of PozGlass cement component
A Kamloops, B.C.-based company has completed the first pour of concrete enhanced with an alternative building material made from a product most of us throw away.
Switch to low-cost, low-carbon concrete can happen today, pilot suggests
The switch to low-carbon concrete can take place today with minuscule upcharge, according to the first-year results of a pilot run by Climate Smart Buildings Alliance (CSBA). On a July 31 webinar hosted by the Canada Green Building Council, the findings from the CSBA’s first annual report were discussed by its director David Messer. The industry organization was created to help change the building sector’s culture and business practices around sustainable materials.
Pricing progress: The value of understanding how much your sustainability strategy will cost
GUEST SUBMISSION: COP29 is crunch time for determining how to finance the zero-emissions future. Official negotiations in Baku, Azerbaijan aim to define a way forward on funding through a new collective quantified goal to climate mitigation, loss and damage. Today’s economic climate is challenging, there’s no denying that securing investment and budget needed for sustainability initiatives is harder than ever.
GreeNovel makes big leap to commercializing e-waste recycling process
A technology developed by Montreal startup GreeNovel Inc. is aimed at unlocking the non-recyclable plastics and valuable metals from electronic waste (e-waste) for reuse in the supply chain. Founded in 2019, the company aims to tackle the problem of pollutants in plastic such as lead, mercury and flame retardants. Its procedure decontaminates the plastics of harmful chemicals and extracts those substances for reuse.
Low-carbon construction materials don't have to mean high costs: report
A home-building boom can be achieved with made-in-Canada, low-carbon materials that do not significantly raise construction costs, a report by Clean Energy Canada suggests. With millions of new homes needed to address the country’s housing shortage, the Vancouver-based think tank says the enormous amount of concrete, steel and drywall to supply the construction will come at a significant climate cost. But that can be offset with sustainably made materials for virtually the same cost.

If we’re going to get serious about cutting CO2 emissions, we’d better talk about cement
GUEST SUBMISSION: Unless you’re intimately familiar with cement production, odds are the cement industry’s nowhere near your carbon footprint radar, but it’s a top contributor. The production of Portland cement (the concrete industry standard) creates roughly seven per cent of global carbon dioxide (CO2) emissions, which is unsurprising when you realize for each pound of cement produced, nearly a pound of CO2 is emitted.
BluWave-ai pilot helps Ottawa drivers find optimal EV charge times
BluWave-ai has completed a pilot program for Canada’s first electric vehicle (EV) charging management software in Ottawa involving cars of different makes and backed by artificial intelligence (AI). Using its EV Everywhere app, the Ottawa-based company's AI platform controlled participants’ EV charging. The system determined the best time for charging in order to minimize strain on the Hydro Ottawa grid and tap into renewable energy for the cleanest battery top-ups.
