Purpose and goal
In the feasibility study, the a new circular concept for wear parts has been developed. Complex cast components can be re-manufactured in many cycles with repeated dual-casting of new functional layers, while retaining high added value. The prestudy has confirmed that the concept is long-term economically and environmentally sustainable for specific selected products, but that existing technical solutions must be further developed.
Expected results and effects
Provided that the quality requirements of a cast component can be met, the feasibility study has shown that the circular business model leads to significantly reduced material and energy use during its life cycle. Re-transport from customer to foundry as well as the cast material´s relative share of the re-manufactured component are crucial parameters for both environmental impact and cost outcomes.
Planned approach and implementation
Two component foundries and a manufacturer of plants for the paper and pulp industry participated in the prestudy. The project gave the companies the opportunity to try a whole new product concept with large potential for future growth. A circular business model was formulated based on existing products. In addition, a basic understanding of the technical challenges associated with the process was created.
