Independent report confirms Northstar Clean Technologies liquid green asphalt production process

VANCOUVER, BC, November 12, 2021 / PRNewswire / – Northstar Clean Technologies (TSXV: ROOF) is a cleantech company focused on recovery and recovery of single-use asphalt shingles produce liquid asphalt, fibers and sands while diverting shingle waste from landfills.

The company has a fully built facility in Delta, BC in the marketing phase with stable production expected in early 2022.

At November 9, 2021, Northstar announced the the results of the independent carbon footprint life cycle assessment (LCA), completed by Burgess Environmental Ltd which concludes that Northstar’s liquid asphalt production will produce 60% less carbon emissions compared to the transport of shingles to landfills and the production of virgin asphalt.

British Columbia’s 2017 Best Practice Methodology for Quantification of greenhouse gas emissions was used to calculate emissions associated with fuel and electricity consumption.

Asphalt produced by the Northstar process is a green, renewable circular asphalt with the lowest carbon intensity of any asphalt in North America.

Key takeaways from LCA:

  • Confirms ROOF’s Empower facility is a renewable “circular” industrial solution with lower carbon dioxide emissions
  • Estimated net reduction in greenhouse gas (GHG) emissions of 121.94 kg of carbon dioxide equivalent per tonne of raw material, diverting shingles from landfills and replacing virgin asphalt production at the Empower facility.
  • Estimated net reduction of carbon dioxide emissions in the range of 1,500,000 kg to 3,000,000 kg of carbon dioxide equivalent per year as a function of the production volume at steady state

12 million tonnes of asphalt shingles are sent to landfills each year in United States, equivalent to more 18M barrels of oil or a day of oil production in the United States dumped in landfills each year.

Diverting an oily mountain of old shingles from landfills is a promising business plan, but some “green businesses” are getting dirty downstream.

“In 2019, The New York Times published an article on old toxic solar panels and batteries causing damage to people who collect recyclable materials by hand in poor African communities ”, reported Forbes magazine.

The independent ACV report just got Northstar over this hurdle.

Northstar Bitumen Extraction and Separation Technology (BEST) uses a proprietary process to separate liquid asphalt, fibers and aggregate sands from discarded or defective asphalt roof shingles destined for landfill.

“The demand for bituminous binder in North America is currently highest for interstate highways and roofs, ”says a October 2021 Liquid Asphalt Research Report Prepared By Kin Communications, “Shingles made from asphalt have a purpose which is to be used for roofing structures. “

“Because these shingles are petroleum based, they are not environmentally friendly and their production wastes energy in addition to exacerbating greenhouse gas emissions,” the research report continues.

“LCA analysis quantifies how our operations can help our customers and industry partners deliver circular and ‘green’ renewable asphalt produced with significantly lower carbon intensity,” said Aidan Mills, CEO of Northstar.

Empower plant carbon dioxide emissions:

  • 77.21 kg of carbon dioxide equivalent produced per tonne of raw material

??Virgin production and landfill carbon dioxide emissions:

  • 44.09 kg of carbon dioxide equivalent produced from one tonne of raw material sent to landfills.
  • 155.06 kg of carbon dioxide equivalent produced from 1 tonne of virgin asphalt, including transport to the Vancouver market (1)
  • A combined total of 199.15 kg of carbon dioxide equivalent per tonne of feedstock

Net savings:

  • 121.94 kg of carbon dioxide equivalent per tonne of raw material

“The global context of reduce the industry’s carbon footprint forces companies to identify other renewable avenues, ”Mills continued. “With the reduced carbon footprint solution for asphalt shingle reuse, we believe we can support our customers and industry partners on their journey to sustainability. “

In addition to the net carbon dioxide savings, the LCA report calculates that the Empower installation will: 1. Reduce water consumption by 650 liters per tonne of asphalt treated 2. Reduce soil disturbance by 0.44 m2 per ton of asphalt treated.

“Depending on the regulatory and legislative framework, the benefits of carbon dioxide emissions may allow Northstar to potentially generate future revenues and margins from sale of carbon credits“said ROOF.

In British Columbia, carbon credits are estimated at around $ 50/tonne.

“A carbon credit is a kind of permit which represents 1 tonne of carbon dioxide removed from the atmosphere”, explains NBC News, “They can be purchased by an individual or, more commonly, by a company to offset carbon dioxide emissions from industrial production. “

ROOF’s business model provides for four sources of revenue: 1. dumping fees (paid by waste haulers and roofing contractors), 2. selling asphalt, 3. selling fiber, and 4. selling of aggregates.

The sale of carbon credits would add a 5e income stream.

For the shareholders of ROOF, the most important ripple effect of the life cycle assessment report, is probably not the value of the carbon credits – but the confirmed value ROOF technology eligibility for government funding.

The ROOF installation is modular and can be duplicated in other locations. As the company expands its operations, governments can be valuable partners, reducing the need for dilutive financing.

At July 27, 2021 Northstar announced that they have engaged Wellington Dupont Public Affairs lead the government’s commitment to reducing the disposal of single-use asphalt shingles in landfills through Canada.

Wellington support federal, provincial and municipal engagement in executing Northstar’s expansion plans through North America, in addition to evaluating various potential non-dilutive funding strategies, including government grants, to support expansion plans, ”said Northstar.

“The retail price of bituminous cement per tonne per August 2021 is in CAD $ 891.00, according to the Ontario Asphalt Pavement Council. This represents an increase of 44% since the beginning of the year “, reports the Kin Communication report.

“We now know that our production process can make a significant difference to our climate by reducing carbon dioxide emissions both in the degradation of asphalt shingle slabs in landfills and in the production of virgin asphalt.” Mills said after the publication of the independent carbon footprint lifecycle assessment (LCA).

“The first step on the road to carbon neutrality is to accurately quantify corporate emissions and LCA quantifies exactly that,” Mills concluded.
