Is storing CO2 in waste concrete the solution we need?

1. Reduces carbon emissions: Storing CO2 in waste concrete helps to mitigate the release of greenhouse gases, which is crucial for combating climate change.
2. Utilizes waste materials: The process makes use of construction waste, providing a practical solution for recycling and repurposing materials that would otherwise go to landfill.
3. Commercial-scale implementation: The inauguration of a commercial-scale carbon capture plant demonstrates the feasibility and potential scalability of this technology.
4. Academic collaboration: The partnership between Neustark and ETH Zurich university showcases the benefits of collaboration between industry and academia in addressing environmental challenges.

1. Limited scope: While the plant is a step in the right direction, it may not be sufficient to fully address the scale of global carbon emissions.
2. Cost implications: Implementing carbon capture technology can be expensive, and it remains to be seen whether the benefits outweigh the costs in the long term.
3. Technological challenges: The efficiency and effectiveness of storing CO2 in waste concrete may still need further improvement and refinement.
4. Regulatory hurdles: The project’s success may depend on supportive policies and regulations to incentivize widespread adoption and overcome potential obstacles.


Neustark, a spin-off from ETH Zurich, has opened its inaugural commercial-scale carbon capture plant in the EU. The plant is situated at a construction waste recycling facility near Berlin, and was developed in collaboration with buil…
