Cost-Efficient carbon dioxide Adsorbents from Low-value Polymers

In-line with the Paris Agreement to limit global mean temperature rise to 2°C, and to pursue efforts to further limit it to 1.5°C, Sweden has set a goal to reach zero-net greenhouse gas emission by 2045. To contribute to meet this goal, industries have come up with various roadmaps wherein measures have been identified that can help them to become climate neutral. Among these measures is carbon capture and storage (CCS). Generally, 70–80 % of the overall CCS cost is related to CO₂ separation from various flue gases wherein the CO₂ separation material and its associated separation process are the key cost elements. Thus, the development of cost-efficient CO₂ separation materials and processes is crucial for the economic viability of CCS. RISE Research Institutes of Sweden together with academia and industrial partners are currently developing various cost-efficient CO₂ separation materials among which is a Polyurethane (PUR)-based CO₂ adsorbent. PUR waste is most often direct combusted leading to CO₂ emission. Instead of directly combusting this waste, RISE and industrial partners namely Powerpipe Systems AB, PUR-gruppen, Loxitec, Plixxent, Nässjö affärsverk AB, are developing a cost-efficient CO₂ adsorbent for industrial CCS application.
