Northstar Secures $2.1M as TAMKO Accelerates Circular Asphalt Economy

CALGARY, AB – October 20, 2026 – In the race to decarbonize heavy industry and secure resilient supply chains, the transition from a linear "take-make-dispose" model to a circular economy is no longer just an environmental mandate—it is the ultimate competitive advantage. This reality was underscored today as Northstar Clean Technologies Inc., a Canadian waste-to-value innovator, announced the closing of an initial C$2.14 million strategic investment tranche from Allmine Paving, LLC, a subsidiary of roofing giant TAMKO Building Products LLC.

The financing, which comes in the form of three-year unsecured convertible debentures, represents a critical milestone in Phase 2 of an overarching US$10.0 million strategic investment package. But beyond the balance sheet, this capital injection signals a profound shift in how traditional building product manufacturers are leveraging cleantech innovators to close the waste loop, secure raw materials, and insulate themselves from the volatility of global commodity markets.

Strategic Industrial Backing: De-Risking the Circular Economy

For decades, the asphalt roofing industry has grappled with a massive, localized waste problem. Millions of tons of discarded asphalt shingles are sent to over-crowded North American landfills annually. Northstar's proprietary design process intercepts this waste stream, extracting liquid asphalt, aggregate, limestone, and fiber for reuse in new hot mix asphalt, flat roof systems, and construction products.

TAMKO's continued financial commitment is not merely a passive capital deployment; it is a strategic maneuver to de-risk its own supply chain. By backing Northstar, TAMKO is effectively securing future access to sustainable, recycled asphalt at a time when virgin petroleum-based products face increasing regulatory and pricing pressures.

The strategic alignment is codified in a robust, four-year Memorandum of Understanding (MOU) between the two entities. Under this agreement, TAMKO has committed to offtake agreements for a significant portion of the asphalt and aggregate produced by Northstar's initial United States facilities. TAMKO's own research and development division has rigorously tested and validated the use of Northstar's recycled asphalt in new roofing products, providing the ultimate commercial endorsement for the Calgary-based cleantech firm.

Furthermore, the partnership extends to physical expansion. The companies are actively collaborating to identify and develop locations for Northstar's US facilities. With a stated goal of establishing three facilities annually, the initial US sites will be heavily supported by TAMKO's offtake agreements, virtually eliminating the demand-side risk that typically plagues early-stage industrial technology scale-ups. This deep integration is further cemented by TAMKO's representation on Northstar's board of directors, ensuring strategic lockstep as the company transitions from demonstration to commercial dominance.

The Financial Mechanics: Balancing Debt, Dilution, and Grants

Navigating the cost of capital in a high-interest environment is a formidable challenge for emerging cleantech companies. Northstar's approach reveals a sophisticated, multi-layered capital structure that blends strategic corporate venture capital, convertible debt, insider participation, and milestone-linked public grants.

The latest C$2,138,400 subscription carries a 10% annual interest rate, payable semi-annually in cash or payment-in-kind. The debentures are convertible into units at C$0.29 per unit, with each unit comprising one common share and one-half of a non-transferable warrant exercisable at C$0.50.

From a dilution perspective, this specific tranche is significant. The conversion of the debentures at C$0.29 would result in approximately 7.37 million new common shares. If the associated warrants are fully exercised, an additional 3.68 million shares would enter the market, representing a potential total equity dilution of over 11 million new shares. However, the inclusion of a statutory four-month hold period—restricting trading before February 17, 2027—provides a necessary buffer against immediate market volatility.

Notably, company insiders participated in this private placement, qualifying it as a "related party transaction" under Multilateral Instrument 61-101. While reliant on exemptions from formal valuation, this insider participation signals strong internal confidence in the company's trajectory and its ability to execute its commercialization plan.

To date, Northstar has drawn down approximately C$13 million from the broader TAMKO investment framework, beginning with a C$8.48 million preferred share placement in Phase 1, followed by milestone-triggered tranches in Phase 2.

Public Grants and the Final Verification Holdback

The structure of this financing also highlights the critical role of public funding in accelerating industrial decarbonization. A remaining balance of C$237,600 under this current Tranche 2 is contingent upon the release of a project holdback from Emissions Reduction Alberta (ERA).

ERA, a provincial funder dedicated to cutting industrial emissions, previously awarded Northstar a grant tied to strict operational milestones. The achievement of ERA Milestone 3 (commissioning of the Empower Calgary Facility) successfully triggered the first tranche of Phase 2 funding. Recently, Northstar achieved ERA Milestone 4, which relates to the actual commercial operation of the Calgary facility, unlocking a C$440,000 payment from ERA and setting the stage for this latest TAMKO investment.

The outstanding C$237,600 holdback represents the final administrative and technical verification of Milestone 4. Once ERA's technical reviewers officially sign off on the facility's operational and emissions performance metrics, this final capital will flow, demonstrating how public grant verification acts as a powerful de-risking mechanism for private and strategic investors.

Landfills to Roads: Scaling the Calgary Blueprint

The ultimate proving ground for Northstar's technology is its Empower facility in Calgary, Alberta. The facility is designed not just as a technological showcase, but as a highly replicable, commercially viable blueprint.

Operations at the Calgary plant are underpinned by a dual-revenue model that drastically reduces early-stage financial friction. On the front end, local Calgary landfills have committed to supplying discarded shingles for five years, paying Northstar tipping fees to take the waste. On the back end, Northstar has secured a sales agreement with McAsphalt to purchase the liquid asphalt produced by the plant. This "paid-to-take, paid-to-make" structure is the holy grail of circular economy economics.

With operational improvements implemented throughout 2026 to address bottlenecks, the facility is targeting an interim processing volume of 100 to 150 tonnes per day. The company's engineering roadmap aims to scale production from 40,000 tons to 80,000 tons without requiring massive additional capital expenditures.

As Aidan Mills, President and CEO of Northstar, recently noted, the company has reached an "absolute tipping point." It is no longer merely a speculative technology play; it is an operating industrial facility generating real-world data, revenue, and product.

Looking ahead, Northstar has identified over 30 potential locations across North America for 24/7 operations, utilizing a site-selection matrix based on city size, local asphalt pricing, and regional tipping fee economics. With planned expansions targeting major metropolitan areas like Hamilton, Ontario, and Baltimore, Maryland, the company is positioning itself to capture a massive, untapped market.

In a global economy increasingly defined by resource scarcity and carbon constraints, the ability to transform municipal liabilities into high-value industrial assets is paramount. Northstar Clean Technologies, armed with TAMKO's strategic capital and a proven operational blueprint, is not just recycling shingles—it is paving the road toward a decentralized, resilient, and highly profitable circular industrial base.
