NORTHSTAR'S CALGARY SCALE UP ASPHALT SHINGLE REPROCESSING FACILITY FOUND TO REDUCE CARBON DIOXIDE EQUIVALENT (CO2e) EMISSIONS BY 60%

Rhea-AI Summary

Northstar Clean Technologies Inc. announced favorable results from an independent life cycle assessment (LCA) of its Calgary asphalt shingle reprocessing facility. The LCA confirms that the facility will produce 60% lower carbon dioxide equivalent (CO₂e) emissions compared to traditional methods, with a potential annual reduction of 3,500 to 4,700 tonnes of CO₂e. The facility aims to be a sustainable solution for asphalt shingle waste, contributing to the circular economy in North America.

Positive

• 60% lower CO₂e emissions compared to virgin production and landfill disposal.
• Net estimated savings of approximately 117 kg of CO₂e per tonne of feedstock.
• Potential annual savings of 3,500 to 4,700 tonnes of CO₂e depending on production volume.
• Long-term revenue potential from carbon credits and tipping fees.

Negative

• None.

Independent life cycle assessment of Northstar's Calgary scale up facility confirms carbon dioxide equivalent emissions benefits vs. landfilling asphalt shingles and use of virgin materials

VANCOUVER, BC, May 26, 2022 /PRNewswire/ - Northstar Clean Technologies Inc. (TSXV: ROOF) (OTCQB: ROOOF) ("Northstar" or the "Company") is pleased to announce the positive results of a second independent carbon dioxide equivalent ("CO₂e") life cycle assessment ("LCA") completed by Burgess Environmental Ltd. ("Burgess") for selected performance indicators for Northstar's planned scale up asphalt shingle reprocessing facility in Calgary, Alberta ("Calgary Empower Facility"). The LCA is based on sophisticated modeling from the front-end engineering design ("FEED") completed by BBA Inc. ("BBA"), 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."

Additionally, depending on the regulatory and legislative framework, carbon dioxide equivalent emissions benefits may allow Northstar to potentially generate future revenue and margins from carbon credits, in addition to the expected revenue streams from incoming tipping fees and from the sale of its end-use products: liquid asphalt, fibre, and aggregate.

LCA Results Summary

The LCA compared the following performance indicators for the Calgary Empower Facility to virgin asphalt production and landfill disposal of discarded or defective asphalt shingles:

• Carbon dioxide equivalent emissions
• Land disturbance
• Water consumption

CO₂e emissions from the Calgary Empower Facility are expected to be 60% lower than the emissions related to virgin production and landfill disposal of the asphalt shingles, emitting 77 kg of carbon dioxide equivalent per tonne of feed stock compared to 195 kg of carbon dioxide equivalent per tonne of feedstock for virgin production and landfill disposal. This implies a net carbon emission savings of 117 kg of carbon dioxide equivalent per tonne of feedstock. Assuming that the Calgary Empower Facility operates five days per week and 52 weeks per year and has a production range of between 150 and 200 tonnes per day, net estimated carbon dioxide emission savings are expected to be in the range of 3,500 tonnes to 4,700 tonnes of carbon dioxide equivalent per year. In addition, each 1 tonne of feedstock processed is expected to reduce water consumption in the range of 18,000 m³ to 24,000 m³ per year and avoid land disturbance in the range of 13,800 m² to 18,400 m2 0.46 m² per year.

About Northstar

Northstar Clean Technologies Inc. is a Vancouver-based clean technology company focused on the sustainable recovery and reprocessing of asphalt shingles. Northstar has developed a proprietary design process for taking discarded asphalt shingles, otherwise destined for already over-crowded landfills, and extracting the liquid asphalt, aggregate and fiber for usage in new hot mix asphalt, construction products and other industrial applications. Focused on the circular economy, Northstar plans to reprocess used or defective asphalt shingle waste back into its three primary components for reuse/resale at its Empower Pilot Facility in Delta, British Columbia. As an emerging innovator in sustainable processing, Northstar's mission is to be the leader in the recovery and reprocessing of asphalt shingles in North America, extracting the recovered components from asphalt shingles that would otherwise be sent to landfill.
