Project background
The built environment (buildings and infrastructure) makes up about a third of Finland’s climate emissions. Most of the carbon dioxide emissions in the built environment are caused by the consumption of energy during use, but a significant part is also formed by concrete construction and especially the use of cement in it. In the cement manufacturing 700 kilograms of CO2 per ton of clinker is released through a chemical reaction. CARBON BUSINESS – Towards a sustainable business with CO2 curing of concrete project is a continuation of the already implemented BECO – The role of concrete in a carbon neutral society and Concrete as a carbon sink – solutions for low carbon construction (BEHI) projects, in which a method has been developed to bind gaseous recycled carbon dioxide permanently to the end product while improving the concretes strength and speeding up the initial phase hardening.
CARBON BUSINESS – Towards a sustainable business with CO2 curing of concrete project continues the work of previous projects towards the industrial utilization of the results and answers the follow-up questions raised by the promising results achieved in the previous projects in the target companies. The goal of the project is to test and identify profitable carbon dioxide feeding technologies, determine the optimal binder composition and carbon dioxide binding amount, ensure the availability of recycled carbon dioxide profitably on the necessary scale, and examine the technical and economic viability of carbon dioxide curing as a whole.
Goal is to provide industry a viable product that uses CCUS carbon dioxide
The knowledge about different solutions generated in the project improves the possibility of concrete industry operators for sustainable, overall economic solutions that promote the reduction of greenhouse gases. As a long-term result, Kymenlaakso region is expected to get new business opportunities, business-oriented piloting and more impressive RDI cooperation.
The goal of CO2 curing is to utilize the captured CO2 from factories. Upscaling CO2 curing to concrete plants the industry is provided with a viable use which encourages the multiple industries to invest and move towards carbon capture technologies. Right now the most common use for recycled CO2 is to store it permanently to emptied oil fields for example in Norway. Alternative solutions for utilization of captured CO2 are relevant.
Project procedures
The goal of the project is to develop CO2 curing process of concrete comprehensively keeping in mind the profitability, achieved emission reductions, value and low-carbon effect. The project is divided to five (5) different work packages, which are:
- WP1:
- WP2
- WP3
- WP4
- WP5

Injection of CO2 and its effect for concrete properties
CARBON BUSINESS – Towards a sustainable business with CO2 curing of concrete project studies the effect of CO2 exposure to concrete while the concrete is still in the plastic phase. CO2 is added to fresh concrete in the mixing phase, which enables the benefits of CO2 mineralization to be used in the ready-mix concrete manufacturing.
Concrete – the green material of our time?
Concrete is the most used building material – and for a good reason. Concrete material is durable, strong, long-lasting, multifunctional and economic. The disadvantage comes from the production of concretes key material, cement, since it releases a lot of CO2 emissions. So is it possible that concrete would be described a green material in the future?


Permanent carbon storing
CARBON BUSINESS – Towards a sustainable business with CO2 curing of concrete project aims also to improve the properties of concrete with CO2. The idea isn’t novel, since the subject has been studied already since the 70s. This project focuses on the implementation and applicability of the process for the ready-mix and precast concrete manufacturing.
When CO2 is introduced to concrete during mixing, it mineralizes permanently in the concrete microstructure. This makes the concrete denser and, with optimal additives and SCMs, stronger (compressive strength).
Bonded CO2 is away from the atmosphere and produced concrete is stronger
