Abstract. This research evaluates the environmental impact of adhesive joints in basalt fibre-reinforced thermoplastic composites. Using the Life Cycle Analysis (LCA) method, the study examines the influence of individual components and surface treatments on the environmental footprint by correlating it with the mechanical properties of the bonded joint by virtue of different surface treatments. The main results indicate that polyamide 11, used as a matrix, has a significant impact on the environment, particularly in the production stages. Surface treatments were compared, including acetone cleaning, mechanical abrasion and plasma treatment, which offered superior mechanical performance but higher environmental costs due to the electrical energy required to operate the process chamber. The study also highlights the ecological benefits and the importance of partial material reuse, which reduces environmental impact.
