The engineering industry, as a key industry segment, plays an important role in shaping the economic landscape. However, along with its importance, it carries a great responsibility towards the environment. One of the key trends in the modern engineering industry is the active implementation of technologies aimed at minimizing waste, optimizing the use of resources and reducing emissions of pollutants. The study of these technologies allows us not only to understand their potential, but also to identify opportunities for improving the environmental efficiency of production.
