Core offering

RENCA manufactures and sells proprietary geopolymer-based physical products (re:activ geopolymer cement, re:print 3D printing mortar, re:agent geopolymer reagent, and re:cover fire- and acid-resistant coatings) that use industrial byproducts as raw materials. The company also delivers R&D, formulation, raw materials study, construction consultancy, and external certification services to help clients convert waste streams into sustainable cementitious binders and 3D-printable construction materials.

Product overview

RENCA is a global technology company offering geopolymer-based products and R&D services for sustainable construction and manufacturing. The product portfolio includes four branded offerings: re:activ (geopolymer cement compliant with EN 197/ASTM C-150 standards), re:print (geopolymer mortar for construction 3D printing), re:agent (geopolymer reagent), and re:cover (fire-protective and anti-corrosion coatings). These products are complemented by services including R&D services, construction consultancy, product development and waste management, raw materials study, advanced testing, and external lab certification. The company focuses on converting industrial by-products and waste into sustainable construction materials, reducing CO2 emissions by up to 90% compared to Portland cement.

Partnerships

Three partnerships are on record, tiered core.

• PENTAcoreGTM or Marketing Partner · 4 December 2024PENTA and RENCA collaborate to host a roundtable on carbon reduction in cement, concrete, and 3D printing at Expo City Dubai. The event focused on eco-friendly construction practices and technologies to reduce carbon footprint, with expert-led presentations on sustainable construction practices.
• StrongPrint3DcoreStrategic or Co-development PartnerCollaboration between RENCA Geopolymer International and StrongPrint3D resulted in the world's first 3D printed house made with geopolymer mortar. This partnership marked a significant milestone for both geopolymer materials and 3D printing technologies.
• Dubai MunicipalitycoreStrategic or Co-development PartnerCEO Marina Dudnikova signed an MOU with Dubai Municipality for cooperation in the production of local to Dubai geopolymer mortar for 3D printing, facilitating market entry and adoption in the UAE region.

Direct peers

• Hoffmann Green Cement Technologies: French publicly listed company developing low-carbon and clinker-free cements including geopolymer-based formulations. Directly comparable to RENCA's re:activ product in technology approach, end-market (construction), and value proposition (CO2 reduction vs. Portland cement).
• CarbonCure Technologies: Canadian company that injects captured CO2 into fresh concrete to reduce cement content and permanently mineralize carbon. Comparable as a sustainability-led construction materials technology provider targeting the same developer and ready-mix concrete customers as RENCA.
• COBOD International: Danish 3D construction printer OEM active globally including in the GCC market. Comparable as a 3DCP ecosystem participant; serves as both a potential distribution channel for RENCA's re:print mortar and an adjacent technology provider to RENCA's partner StrongPrint3D.
• Solidia Technologies: US-based company developing low-carbon cement and concrete technologies using CO2 curing and alternative binders. Closely comparable to RENCA in targeting cement decarbonization for the construction industry with proprietary chemistry-driven differentiation.
• ICON: US-based leader in construction-scale 3D printing with proprietary wall systems and Vulcan printer. Directly comparable to RENCA on the 3DCP construction side, where ICON needs materials partners — making ICON both a potential customer and adjacent competitor in the integrated 3DCP building solution space.
• ECOCEM: European leader in low-carbon cement technology using ground granulated blast-furnace slag as a Portland cement substitute. Comparable in targeting cement decarbonization with a technology-led approach serving construction industry customers across Europe.

Emerging players

• BioMason: US-based company producing cement-based building materials using biological processes rather than carbon-intensive kilns. Comparable as an early-stage alternative cement technology company targeting the construction industry with sustainability differentiation.
• Apis Cor: US-based company developing construction 3D printing technology and full-stack building solutions. Comparable as a 3DCP technology provider targeting the same sustainable construction segment where RENCA's geopolymer mortar is positioned as a material input.

Broad incumbents

• Heidelberg Materials: Global cement major with significant investments in carbon-neutral cement technologies, CCUS pilots, and lower-clinker products under its evoZero brand. Comparable as a broad incumbent entering the same low-carbon cement category that RENCA targets, with substantial R&D and deployment resources.
• Holcim: One of the world's largest building materials and cement producers with an aggressive sustainability roadmap including low-carbon and lower-clinker cement portfolios. Comparable as a broad incumbent that competes for the same sustainable construction materials customers, though with vastly greater scale and traditional Portland cement as its anchor product.
