MONTREAL, Canada — HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ) (OTCQB: HPQFF) (FRA: 8PY1), a technology company developing next-generation processes for advanced material manufacturing, is pleased to announce that its France-based affiliate, NOVACIUM SAS (“Novacium”), has been selected to present at ENSURE 2025, the 3rd International Conference on Environmental Sustainability through Waste and Recycling. The event will take place from April 23–25 in Houston, Texas.
Novacium will showcase its latest research in a talk titled “Closing the Aluminum Loop: An Innovative Process for Black Dross Valorization”, highlighting findings from its Waste-to-Energy (W2E) project.
“This selection marks another recognition of the scientific and industrial value of our research,” said Dr. Jed Kraiem, COO of Novacium. “It validates our contribution to sustainable waste management and energy recovery.”
“We’re proud to see Novacium’s work recognized internationally,” said Bernard Tourillon, President and CEO, HPQ Silicon Inc. “Presenting at ENSURE 2025 highlights the relevance of our shared mission: transforming overlooked industrial byproducts into valuable, sustainable resources. It’s an exciting step forward demonstrating how innovation can drive environmental and economic progress.”
THE CONFERENCE
Organized by the United Scientific Group (USG), ENSURE 2025 is a high-impact international conference designed to bring together a diverse community of scientists, industry experts, academics, entrepreneurs, and policy makers. The event fosters cross-disciplinary dialogue on emerging technologies, regulatory strategies, and circular economy models driving environmental sustainability. Participants from academia, industry, and government sectors are expected to attend.
The conference addresses a wide range of urgent and future-focused themes, including, but not limited to:
- Waste-to-Energy technologies
- Circular economy and zero waste strategies
Novacium, in partnership with the Laboratory of Automation, Process and Pharmaceutical Engineering (LAGEPP), under the supervision of the University of Lyon 1 and the French National Center for Scientific Research (CNRS), will present its novel hydrometallurgical process developed as part of the W2E project.
This new proprietary process enables the neutralization of black dross, a toxic aluminum recycling byproduct, while producing green hydrogen and recovering a usable solid. By using a low-cost additive under milder pH conditions, the method surpasses traditional technologies in both safety and efficiency. The approach is also highly flexible, adaptable to various dross compositions, and ready for integration into existing recycling infrastructure (See January 28th, 2025, release).
The research is led and will be presented by Diego Guerrero, a PhD candidate at Université de Lyon 1 and R&D Engineer at Novacium. Diego is a chemical and process engineer specialized in processes for energy and the environment, with a strong academic and research background.
“Black dross is often seen as a waste with limited value. Our work flips that narrative—demonstrating that, with the right approach, it can become a resource for both material recovery and clean energy generation,” said Diego Guerrero, PhD Candidate and R&D Engineer at Novacium. “I’m excited to share our findings at ENSURE 2025 and contribute to the global conversation on sustainable waste solutions.”
HPQ Silicon is a Quebec-based TSX Venture Exchange Tier 1 Industrial Issuer. With the support of world-class technology partners PyroGenesis Canada and NOVACIUM SAS, the company is developing new green processes crucial to make the critical materials needed to reach net zero emissions.
