Capture and
store CO₂
with minerals
At ReZem, we are on a mission to reduce the CO₂ footprint in the cement and concrete industries. Through our innovative material technologies, we aim to create a more sustainable future.

About
At ReZem, we are dedicated to reducing the CO₂ of the global cement and concrete industries. Through our patented innovative technologies and products (4 patents) we aim to solve the environmental challenges associated with cement and concrete production.
Energy Solutions
ReZem, established in 2023 as a demerger from ReStone, is a material technology company that invents and patents technologies and products. The company focuses on a strong ESG heritage, developing scalable technologies to address global challenges related to cement and concrete. This includes reducing CO₂ emissions by using CO₂ in processing and replacing part of the cement in concrete.
Technology
- ReZem® capture and store CO₂ in at mineral
- ReZem® utilize the waste product from the process that will be an environmentally friendly low-CO₂ supplementary cementitious material (SCM)

What is Olivine and how does it work?
Reducing Emissions
Developing technologies that reduce CO₂ emissions and improve sustainability in cement and concrete production.
Innovative Solutions
Creating innovative solutions to address the challenges faced by the cement and concrete industries.
Energy Efficient
Developing energy-efficient technologies to reduce the environmental impact of cement and concrete production.
Research and Industry Collaboration
Collaborating with research partners to drive innovation and develop sustainable solutions for the industry.

Why ReZem?
Global warming caused by CO₂emissions is a first order problem world-wide. Concrete is the most widely used man-made material. Cement is the key ingredient in concrete, and it is the source of 8% of the words man-made annular CO₂emission (approximately 1.5 Gt per year).
Revolutionizing Cement Production
Transforming the Concrete Industry
Leading the Way in Sustainability
ReZem is at the forefront of developing sustainable technologies for the cement and concrete industries. Our product ReZem® has the potential for sequester and store CO₂in the production phase, as well as when used in the concrete as it replaces part of the cement clinker and hence also then reduce the CO₂emission.
Through our innovative solutions, we aim to reduce CO₂ emissions and create a more environmentally friendly future.
The product solves challenges related to durability of the cements and concrete. Examples of well-known pain points in the cement- and concrete industry are durability due to degradation processes, carbonatization, and penetration of chloride into the concrete. These challenges are solved by our product ReZem® as filling of pores and minor cracks in the cement- and concrete creates protection against the degradation processes.
Recent news from ReZem
Nyhetsbrev – Mars 2025
ReZem AS jobber aktivt med utvikling av bærekraftige løsninger for karbonfangst og sementerstatning. Vår teknologi gjør det mulig å lagre CO₂ i mineralske forekomster og omdanne dette til produkter med forbedrede egenskaper for bygg- og anleggsbransjen. Målet er å skape en mer miljøvennlig og sirkulær industri hvor avfall blir en ressurs, og hvor karbonutslipp reduseres betydelig.
Støtte fra Innovasjon Norge og Forregion Norge
Vi har mottatt oppstartstilskudd fra Innovasjon Norge, som bidrar til videreutviklingen av vår teknologi og forretningsmodell. I tillegg har vi fått midler fra Forregion Norge, som støtter forskningsbaserte innovasjonsprosjekter. Dette gir oss muligheten til å gjennomføre viktige tester og analyser som skal dokumentere potensialet i vår løsning.
Deltakelse i forskningssamarbeid
ReZem AS er også invitert til å delta i forskningssamarbeidet SFI Carbon Symphonie, hvor vi jobber med ledende forskningsmiljøer for å videreutvikle teknologi for karbonfangst og mineralisering. Dette er en spennende mulighet til å bygge ny kunnskap og styrke vårt teknologiske fundament.
Veien videre
Vi ser frem til en spennende tid med videre utvikling og samarbeid med industri, forskningsmiljøer og myndigheter. Vårt mål er å skape konkrete og skalerbare løsninger som kan gjøre en forskjell for miljøet og samtidig skape verdier for næringslivet.Patentene har hatt en grundig ekstern vurdering, og vi ser at framtiden blir spennende.
