Establishing our role as a pioneer of magnesia

For more than 50 years, Terresis has been a key player in the magnesia sector. Today, driven by our vertically–integrated model and unique cross-industry expertise, we are pushing the boundaries of innovation to unlock the full potential of this critical resource. Aware of environmental and industrial issues, our development strategy is based on solutions aimed at exploring possibilities, whether it is to reduce our carbon footprint or to develop new applications.

Exploring the full potential of our fields of application

Always on the lookout for exciting challenges, our researchers, technicians and engineers are mobilizing to push the boundaries in four major application areas: animal nutrition and plant production, environmental solutions, industrial minerals and refractory solutions.

As a subsidiary of the Groupe Roullier, we rely on considerable scientific, technical and human resources to experiment with new products and develop visionary magnesium solutions that meet the societal challenges of tomorrow.

This responsible innovation, coupled with a constant search for improvement, translates into an R&D department associated with each of our fields of application, a true place of synergy where innovative ideas and scientific curiosity are transformed into revolutionary breakthrough.

Performance and accountability at every step

Committed to responding to our customers’ concerns and anticipating their future requirements, Terresis is positioned as the preferred partner in a constantly evolving market with a bright future. What makes us different? A strong commitment where the complete control of the value chain guarantees unrivalled reliability and quality.

Extraction, processing and marketing… From our integrated mines where we select the highest quality magnesium, we have complete control over every step of the process. Thanks to this direct access to ore, as well as the close collaboration between our technical, commercial and logistics teams throughout the magnesia lifecycle; our customers benefit from high-performance solutions and safe and sustainable state-of-the-art offers.

With our technical expertise in magnesium acquired over the years, we have also developed a trading activity. This opens-up a stimulating field of possibilities where our experts are committed to finding the best solution for each need.

An ambitious development strategy for 2030

As part of our 3E (Ensure/Enhance/Explore) strategy, Terresis has set itself three priorities:

Establish the sustainability and performance of the ore extraction and processing operations in Brazil and Navarra, in order to maintain a long-term vision for our four areas of application, particularly in view of the environmental challenges that lie ahead;

Fully exploit the potential of our applications through a tailored organization and the enhancement of our products potential, whether from a geographical or sectoral point of view;

Exploring the possibilities and opening up to other products, other fields of application and other services, always as close as possible to the needs of the field.

An ambitious vision that combines responsibility, performance and innovation in order to build the future of magnesia together.

Sustainable development at the heart of our strategy

If sustainable development is the backbone of our strategy, it is because magnesia is an essential resource that we must protect. Each of our decisions, each of our innovations, each of our actions, is part of this fundamental quest: to protect this resource while limiting our environmental impact and ensuring its availability for future generations. To do this, we study the different possible scenarios, from the management of the life cycle of magnesia, to the capture of CO2 emissions. Our ambition: to transform these commitments into concrete solutions for a sustainable future for all.
