持续创新：UPM 推动高性能生物基材料规模化发展

Core Viewpoint - The article discusses the urgent need for the CASE (Coatings, Adhesives, Sealants, Elastomers) industry to transition towards sustainable, bio-based materials due to increasing environmental regulations and the depletion of fossil resources [3]. Industry Pain Points - The CASE industry heavily relies on petroleum-based raw materials, leading to high carbon emissions and vulnerability to fossil resource fluctuations. This creates a pressing demand for high-performance, low-cost, and fully renewable bio-based alternatives [3]. - Lignin, the second most abundant natural polymer, holds significant potential as a substitute for fossil-based aromatic compounds, but its complex molecular structure and variability pose challenges for large-scale application [3]. UPM's Green Initiatives - UPM, a leading forest industry company, is addressing these challenges through its second-generation biomass refining plant in Leuna, Germany, which aims to convert sustainably sourced wood into bio-based chemicals. The plant has a total capacity of approximately 220,000 tons [5]. - Key products from this facility include bio-based ethylene glycol (UPM BioPura™), propylene glycol, and lignin-based renewable functional fillers (UPM BioMotion™), all sourced from 100% sustainably managed forests [5]. Innovations in Wood-Based Chemicals - UPM's innovations include high-reactivity lignin that can partially or fully replace traditional phenol in phenolic resins, enhancing mechanical strength and reducing toxicity [10]. - The unique hydrophobic and film-forming properties of lignin are being explored for barrier coatings in paper-based packaging, improving water and oxygen resistance while promoting biodegradability [10]. Upcoming Events - UPM's manager, Han Dayong, will present at the Bio-based 2026 conference in Shanghai, discussing the latest advancements in wood-based chemicals and their applications in the CASE industry [9][12].
