Abstract [en]

The construction sector is a major contributor to global warming. One solution to the challenge is to develop new sustainable material alternatives. The BioZEment concept employs bio-catalytic dissolution and precipitation of calcium carbonate as a novel alternative to concrete. In this report, the reduction in global warming potential of using BioZEment is assessed with a building stock model, where the use of conventional concrete is compared to the use of BioZEment in Norwegian dwellings until 2100. The assessment is conducted with the assumption that BioZEment has expected material properties and is gradually penetrating the building stock until it reaches a full implementation by 2050.

Results indicate that the use of BioZEment has a higher potential of reducing global warming potential than conventional concrete, regardless of the development of the cement industry. BioZEment could decrease cumulative greenhouse gas emissions with ca 15 % by 2100 compared to using conventional concrete with a conservative development and slightly less if compared to using concrete with an optimistic development (including among other initiatives breakthrough technologies like carbon capture and storage, and carbon capture and utilization).

Results also indicate that, while BioZEment is not fully implemented in the entire building stock, using the optimistic development concrete instead of conservative concrete provides the lowest cumulative emissions by 2100. That means that including several migration strategies at the same time will reduce emissions further than taking one single action.

The building stock model provides interesting indications about the potential of BioZEment, which can guide further development. If Norway is to meet its ambitious goals of emission reductions and climate neutrality, it is important to design thought through and robust strategies for the construction sector.
