Northstar Clean Technologies Inc.has developed a proprietary technology, the “Bitumen Extraction and Separation Technology”, known as BEST, that recycles waste asphalt shingles into their basic components of aggregate, fibre and liquid asphalt. The BEST technology separates all the components of asphalt shingles, providing a 100% waste diversion from landfills. Empower Calgary is expected to process 30,000 – 40,000 tonnes per year of asphalt shingles which will be diverted from Calgary landfill and provide liquid asphalt to the market with a carbon footprint 60% lower than the base case which sends shingles to landfill and replaces the reprocessed liquid asphalt with virgin asphalt production. Northstar’s solution will have a significant impact on advancing Alberta towards a circular economy. It will help to provide the construction industry with clean, sustainable processing solutions, reduce the CO2e impact of asphalt, fibre and aggregate production, and support municipalities in their transition to the circular economy (and away from landfilling waste shingles).
