[System Concept of Production Design and Development in Scrap and Metal Recycling].

The present system concept of metal and scrap recycling plants deals with possible effects of renewed legislative amendments and evaluates legal and technological as well as economical aspects of the value stream oriented shredder process. It is a system oriented approach to point out the main influencing factors on the development of shredder plants in scrap and metal recycling. Those factors are being merged into a superordinate system concept used to support strategic management decisions regarding future investments in the waste treatment sector.Under the given legal circumstances, the shredder process itself has to be resource-friendly, energy- and cost-efficient while still following the stated emission limit values.Therefore, the conceptual focus lies in the argumentation and evaluation of technical challenges as a major result of the implementation of national and international legal terms in the age of volatile market conditions, present recession, and value decline in prematerial compositions. The system concept is the result of a research project from October 2016 to December 2019 at the TSR Recycling GmbH & Co. KG, Lünen, Germany.The concept itself forms a base for the development of plant technology in other metal recycling fields, such as e‑waste recycling. Due to the current COVID-19 pandemic situation, the model is extended to other and further influencing factors and helps to understand the short lifespan of theoretical modelling within the field of scrap metal recycling.
