• UNSW engineers have tackled a longstanding problem at the heart of global agriculture: how to make urea for fertilizer without the intensity of emissions associated with fossil-fuel-powered factories. • The solution is outlined in a study published in Nature Communications.
Article Summaries:
- UNSW researchers have developed a catalyst that can produce urea-an essential fertilizer-by directly coupling carbon dioxide with nitrogen‑containing waste gases, bypassing the high‑emission, fossil‑fuel‑driven processes that dominate the industry. The new method, detailed in a study in Nature Communications, converts CO₂ and nitrogen pollutants into urea in a single, energy‑efficient step, potentially reducing the sector’s carbon footprint and turning waste streams into valuable feedstock. While still in the laboratory phase, the approach could reshape fertilizer production by integrating carbon capture with nitrogen recycling, offering a more sustainable alternative for global agriculture.
