The restrictions imposed on the use of formaldehyde in wood panel adhesives have been the driving force behind the development of formaldehyde-free resins for the manufacture of wood products. Considering as a boundary condition the idea that the use of fossil-based raw materials should be replaced by biological options, there is growing interest in the environmental assessment of different alternatives for soy-based adhesives, as possible options to replace commonly used synthetic resins. This report includes the environmental profiles of soy-based adhesives taking into account the life cycle assessment (LCA) methodology. In addition, in order to increase their potential to replace synthetic resins, a sensitivity analysis of the main contributors to environmental damage was performed, thus giving an open guide for further research and improvement. This study aims to provide innovative alternatives and new trends in the field of environmentally friendly bio-adhesives for the wood panel industry.

对木板粘合剂中甲醛使用的限制一直是开发用于木制品制造的无甲醛树脂的推动力。考虑到化石原材料的使用应被生物材料替代的想法作为边界条件，人们对大豆基粘合剂的不同替代品的环境评估越来越感兴趣，作为替代常用合成树脂的可能选择。该报告包括考虑到生命周期评估（LCA）方法的大豆基粘合剂的环境概况。此外，为了提高其替代合成树脂的潜力，对环境损害的主要因素进行了敏感性分析，从而为进一步的研究和改进提供了开放的指导。本研究旨在为木板行业环保生物粘合剂领域提供创新替代方案和新趋势。
