1. 1

   CLO 1: The general learning outcomes of the "recycling of materials" subject allow students to deeply master the recycling technologies of various materials (metal, plastic, glass, paper, etc.), the principles of circular economy and sustainable development. students learn the methods of waste sorting, physical-mechanical and chemical processing, and acquire the ability to analyze the processes of industrial reuse of recycled raw materials. during the course, they learn to carry out environmental impact, economic efficiency and product life cycle assessment (lca) of recycling processes. at the same time, future specialists acquire the skills to develop engineering solutions in accordance with the principles of ecological design (eco-design), so that the products to be produced can be recycled more easily in the future. in the end, this complex knowledge obtained allows to implement effective projects in the field of waste minimization and economical use of resources in the industry.
