Geopolymers represent a revolutionary alternative to Portland cement, being produced from industrial by-products such as fly ash and metallurgical slag. This technology reduces CO₂ emissions from traditional cement production by up to 80%.

Research conducted by European universities shows that geopolymer-based concrete offers mechanical strengths comparable to those of conventional concrete, while ensuring superior durability in aggressive environments. Production costs are currently 10–15% higher, but they are expected to decrease as industrial-scale production expands.

In Romania, the first experimental projects using geopolymers are being carried out in collaboration with research institutes and companies from the industrial sector. These materials can be applied in road infrastructure, industrial constructions, and residential buildings, providing an eco-friendly solution to reducing the carbon footprint.

In the medium term, the adoption of geopolymers could position Romania as a regional leader in sustainable construction materials, supporting the transition toward a circular economy.
