Core Viewpoint - The supercritical carbon dioxide-assisted polyurethane spray technology developed by Zhejiang Huachuang and Nanjing Forestry University has received global recognition for its potential to transform the polyurethane spray industry towards greener practices [1][2]. Group 1: Technology Development - The technology utilizes the unique properties of carbon dioxide in a supercritical state to create a polyurethane foam that is free of ozone-depleting substances (ODS) and has a very low global warming potential (GWP) [1]. - This innovation has been recognized as the only fully proprietary technology in the world that meets these environmental standards [1]. Group 2: Economic and Environmental Impact - The technology has been successfully applied in various domestic projects, achieving a total of 150,000 cubic meters of hard foam spraying, which has replaced and reduced the use of HCFC-141b blowing agent by 520 tons, resulting in a reduction of ODP equivalent by 57.2 tons and a decrease in carbon dioxide equivalent by 377,000 tons [2]. - The technology has demonstrated significant economic and social benefits, showcasing a high cost-performance ratio and providing crucial technical support for the phase-out of HCFC-141b in the polyurethane foam industry [2]. Group 3: International Collaboration and Future Prospects - The company has initiated technical training in developing countries like India, aiming to promote the technology globally [2]. - Representatives from multiple countries have expressed interest in deepening cooperation with China on technology promotion, highlighting the dual value of environmental protection and economic benefits [2].
