Bio-based adhesives could be an important addition to dispersion- and solvent-based adhesives due to increasing environmental and health requirements. This could also improve the environmental impact of many composite products. The aim of this review is to examine whether adhesive technologies have already been investigated for their environmental impact and if so, which biomass has been used for which type of adhesive. For this purpose corresponding studies were conducted and a total of 563 different peer-reviewed articles on adhesives identified. These articles were then evaluated in a 2-step screening process. Articles in which adhesives themselves, and not just composite products, have already been examined with regard to their environmental impact have been analyzed in detail to determine whether adhesive technologies based on renewable raw materials have significant better environmental performance than conventional reference products. The results provide a comprehensive critical overview of the latest developments in the industry. It becomes clear that the environmental performance of industrial bio-based adhesives is still very controversial and mostly based on assumptions of theoretical and unproven products. The fact that many of the conversion technologies used are still only tested in the laboratory or in the pilot phase and have not yet been implemented to an industrially relevant extent still represents a significant obstacle to the implementation of novel bio-based value chains and leads to additional uncertainties in the decision-making process. However, 70% of the theoretical adhesives or existing adhesives, which also consist of only a fraction of renewable raw materials, show equally good or better environmental performance. Especially the impact category global warming and human toxicity indicate a high potential for improvement. In addition, it becomes clear that vegetable oils and starch are particularly suitable as biomass for the green production of adhesives. Although the literature shows a theoretical potential for industrial bio-based adhesives, the market is still immature and is based on a low development of bio-based adhesive options. Against this background, it must be the aim of further scientific work to fill this specific gap by modelling the life cycle of bio-based adhesives from an environmental and economic perspective, which shows the results clearly and transparently and thus also guarantees a good basis for decision makers.

由于对环境和健康的要求不断提高，生物基胶粘剂可能成为分散基和溶剂基胶粘剂的重要添加。这也可以改善许多复合产品对环境的影响。这篇综述的目的是检查是否已经对粘合剂技术的环境影响进行过研究，如果是，则对哪种生物质用于哪种类型的粘合剂进行了研究。为此，进行了相应的研究，确定了总共563篇关于胶粘剂的同行评审文章。然后在两步筛选过程中评估这些物品。粘合剂本身而不仅仅是复合产品的制品，已经对它们的环境影响进行了详细分析，以确定基于可再生原料的粘合剂技术是否具有比常规参考产品显着更好的环境性能。结果为该行业的最新发展提供了全面而关键的概述。很明显，工业生物基粘合剂的环境性能仍然存在很大争议，并且主要基于理论和未经验证的产品的假设。所使用的许多转换技术仍仅在实验室或试验阶段进行测试，尚未在工业上实现相关程度的事实，仍然构成实施新型生物基价值链的重大障碍，并导致决策过程中的其他不确定性。但是，70％的理论粘合剂或现有的粘合剂（也仅由一部分可再生原料组成）显示出同样良好或更好的环境性能。特别是影响类别全球变暖和人类毒性表明有很大的改进潜力。另外，很明显，植物油和淀粉特别适合作为绿色生产粘合剂的生物质。尽管文献显示了工业用生物基胶粘剂的理论潜力，但市场仍然不成熟，并且是基于生物基胶粘剂选择的低发展。在此背景下，必须进行进一步的科学工作，以从环境和经济的角度对生物基胶粘剂的生命周期进行建模，以填补这一具体空白，从而清楚，透明地显示结果，从而为决定者。
