The following are examples of the Group’s recent R&D projects and progress, demonstrating our commitment to sustainability, technological leadership, and long-term value creation across all business areas.
Environmental Remediation: Innovative waste recovery through pyrolysis
As part of its commitment to closing industrial material cycles, the Group launched a multi-year R&D initiative focused on the pyrolytic treatment of selected waste streams. The project targets:
- Plastic-based waste from dismantled technical components e.g. such as car batteries
- Sludge residues with hydrocarbon content
The aim is to achieve material and energy recovery via pyrogasification, with the potential to generate hydrogen (H₂) in a technically and economically viable manner. Upon successful implementation, the solution is expected to eliminate up to 4,000 tons of landfill-bound waste annually and produce reusable gas fractions.
The recovered gases may be refined for internal use, injection into distribution networks, or resale for industrial applications – in line with EU waste hierarchy principles and the Group’s decarbonization roadmap.
The project contributes directly to national and European hydrogen strategies and supports the development of a circular, low-emission waste treatment process. Feasibility studies are currently underway, with the next phase targeting pre-industrial validation.
Industrial Coatings: Sustainable rehabilitation of corroded tank infrastructure
In the field of industrial asset protection, the Group developed a new coating system for corroded floating roofs in storage tanks. This innovation enables structural rehabilitation under full operating conditions – eliminating the need to empty tanks and thereby minimizing downtime and operational risk.
The system integrates:
- Hydrodynamic surface preparation
- Solvent-free, highly flexible epoxy and polyurethane laminates
- A final layer with reflective, durable, and chemical-resistant properties
This approach extends asset lifetime, improves operational safety, and enhances sustainability by preserving existing infrastructure. The technology also provides a competitive advantage in niche markets with high performance requirements and regulatory complexity.
