- A Plastic System Born from CO₂, Returning to Fertilizer and Raw Materials: Demonstrating a New Polymer Resource Cycle for Carbon and Nitrogen
- A joint research group from Chiba University, the University of Tokyo, and Kyoto University has developed a new cross-linked aliphatic polycarbonate material. It is produced using carbon dioxide (CO₂) as a raw material and can be decomposed into plant fertilizer (urea) and raw material precursors by treating it with ammonia water after use. Furthermore, they have succeeded in regenerating the original raw materials from the decomposed products using CO₂ again. This research, published in the Journal of CO2 Utilization on June 18, 2026, demonstrates a novel polymer resource circulation system that integrates a "carbon cycle," which utilizes and recycles CO₂-derived carbon as a polymer material, and a "nitrogen cycle," which utilizes nitrogen components as urea fertilizer through polymer decomposition.
