Northstar Clean Technologies Inc. announces the positive results of a second independent carbon dioxide equivalent life cycle assessment completed by Burgess Environmental Ltd. for selected performance indicators for Northstar’s planned scale up asphalt shingle reprocessing facility in Calgary, Alberta. The LCA is based on sophisticated modeling from the front-end engineering design completed by BBA Inc., Northstar’s engineering consultant, on March 25, 2022. The LCA assessed the impacts and benefits of reprocessing asphalt shingles and compared them to the impacts and benefits related to the disposal of discarded or defective asphalt shingles in landfills and virgin production of asphalt shingles.

Highlights from the Calgary Empower Facility LCA:
  • Based on the FEED design, the Calgary Empower Facility will have lower CO2e emissions than landfilling and virgin production and therefore provides a sustainable industry solution for reusing asphalt shingles.
  • Net estimated greenhouse gas emission savings of approximately 117 kg of CO2e per 1 tonne of feedstock(1).
  • Net estimated CO2e emission savings in the range of 3,500 tonnes to 4,700 tonnes of CO2e per year(1) depending on production volume.

Calgary Empower Facility’s Carbon Dioxide Emissions:

  • 77 kg of carbon dioxide equivalent produced per 1 tonne of feedstock(1)

Virgin Production and Landfill Disposal Carbon Dioxide Emissions:

  • 44 kg of CO2e produced from 1 tonne of feedstock routed to landfills.(1)
  • 603 kg of CO2e produced from 1 tonne of virgin asphalt, including transportation to the Calgary market(1) (151 kg of CO2e per 1 tonne of feedstock)
  • Total of 195 kg of CO2e per 1 tonne of feedstock

Net Savings:

  • 117 kg of CO2e per 1 tonne of feedstock (approximately 60% net savings)

Aidan Mills, President & CEO and Director of Northstar, states, “We are very happy with the results of our second independent LCA for the Calgary Empower Facility. The results show strong potential CO2e emission savings of 60% for our Calgary Empower Facility over virgin production and landfill disposal carbon dioxide equivalent emissions. The completion of the LCA is another step towards the development of our Calgary Empower Facility and builds on the momentum of the completion of the FEED design and awarding of non-dilutive grant funding from Alberta Innovates. This analysis quantifies how our operations in Alberta can support our customers and industry partners in delivering circular and “green” renewable asphalt produced with significantly lower carbon intensity. The industry needs to significantly reduce its carbon emissions and landfill disposal, and we are working to become a sustainable solution for reprocessing asphalt shingles across North America.”

Mr. Mills also said, “Our long-term vision is to be an environmentally responsible, sustainable clean technology company delivering renewable products with a significantly lower carbon intensity. In addition to the full diversion of asphalt shingles from landfills, we now know our production process can deliver a meaningful reduction in CO2e emissions and make a significant contribution to the circular economy in the asphalt industry. We are committed to the long-term sustainability of our operations and are very pleased to see that our clean technology is proving itself to be a significant contributor in the transition to a low carbon economy.”
