Bio-based polyurethane, which utilizes plant oil, straw, and lignin as raw materials, has become a core direction for the industry's "dual carbon" transformation due to its low carbon emissions, degradability, and renewability. The global production capacity is expected to exceed 5 million tons by 2026. Leading domestic enterprises have achieved mass production of bio-based MDI and bio-based polyols. Jiangsu Youluyue is actively deploying trade in bio-based materials to promote green upgrading of the industrial chain.
