Collection and Separation Facility is an important intermediate process in which recoverable wastes from different sectors are accepted, classified and prepared for the recycling chain in an organized manner. Within the scope of its R12 license, MYK Grup separates many material groups such as plastic, metal, glass, wood, textile, paper-cardboard and similar materials according to their source and material type. This structure prevents waste mixing, helps preserve material quality, increases recovery efficiency and supports companies in managing their environmental obligations more accurately. The codes listed under the subcategories have been organized to present accepted waste groups to users with clearer and topic-specific explanations.
