Design-Deconstruction-Recycling for Retained Metal Value

Important results from the project

The project has produced the results that we planned, although it turned out that the connection to standards and legislation was not as direct as we might have initially thought. The model that was set up for increased recycling of alloying elements and avoidance of harmful substances could be studied with synthetic data and partially verified with real data.

Expected long term effects

DesignValue lays the foundation for consensus on how scrap with different compositions should be kept separate and what requirements this places on product information (dpp) and logistics. A relevant conceptual framework and adequate calculation methods for alloy recycling and trace elements can be developed and standardised. Changes in the market based on small profitable steps is then possible. When it can be shown what is reasonable to demand, goals can be introduced into legislation.

Approach and implementation

The project was carried out in three seminars with intermediate project work: 1. Background information on Steel and the metal cycle. 2. Handling data on complex products, modeling scrap management. 3. Discussion of legislation and presentation of two case studies. DesignValue has collaborated with KTH and the Horizon2020 project MEDALS. A BSc-dissertation and a seminar paper at KTH have been produced in the project. Results and thoughts have been presented at several international seminars.
