HPQ Silicon Inc., a technology company pioneering next-generation processes for advanced material manufacturing, is proud to announce that its France-based affiliate, NOVACIUM SAS (“Novacium”), has been invited to present at ENSURE 2025 — the 3rd International Conference on Environmental Sustainability through Waste and Recycling. The event is scheduled to take place from April 23 to 25 in Houston, Texas.
Novacium will present its latest research in a talk titled “Closing the Aluminum Loop: An Innovative Process for Black Dross Valorisation,” showcasing key insights from its Waste-to-Energy (W2E) project. Organised by the United Scientific Group (USG), ENSURE 2025 is a prominent international conference that brings together a diverse community of scientists, industry leaders, academics, entrepreneurs, and policymakers.
“This selection marks another recognition of the scientific and industrial value of our research.It validates our contribution to sustainable waste management and energy recovery, “said Dr. Jed Kraiem, COO of Novacium.
The event aims to facilitate cross-disciplinary discussions on cutting-edge technologies, regulatory frameworks, and circular economy models that are shaping the future of environmental sustainability. Attendees from academia, industry, and government sectors are expected to take part in this impactful gathering.
“We’re proud to see Novacium’s work recognised internationally. 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,” said Bernard Tourillon, President and CEO, HPQ Silicon Inc.
In collaboration with the Laboratory of Automation, Process and Pharmaceutical Engineering (LAGEPP)—a joint initiative under the University of Lyon 1 and the French National Centre for Scientific Research (CNRS)—Novacium will present its innovative hydrometallurgical process, developed as part of the W2E project.
This proprietary new process offers a groundbreaking solution for neutralizing black dross—a hazardous byproduct of aluminium recycling—while simultaneously generating green hydrogen and recovering a usable solid material. Utilising a cost-effective additive under milder pH conditions, the method significantly improves upon conventional technologies in terms of both safety and efficiency. Notably versatile, the process can adapt to a range of dross compositions and is designed for seamless integration into existing recycling systems.
“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. I’m excited to share our findings at ENSURE 2025 and contribute to the global conversation on sustainable waste solutions,” added Diego Guerrero, PhD Candidate and R&D Engineer at Novacium.
The research is led by Diego Guerrero, a PhD candidate at Université de Lyon 1 and R&D Engineer at Novacium. A chemical and process engineer with a focus on energy and environmental technologies, Diego brings a strong academic and research background to the project and will present the findings at the conference.
