| Abstract |
The paper describes the results of experimental development work carried out at the company RADO Sp. z o.o., which has resulted in the development of a technique for obtaining dendritic copper powders from copper granules extracted from waste jelly-filled copper-core cables with a steel suspension wire. The process is carried out in a single manufacturing operation. The research work was performed as part of a project co-financed by the Intelligent Development Operational Programme 2014-2020, Measure 1.2,Sector R&D programmes" managed by the National Centre for Research and Development in Warsaw. After performing key experimental work and obtaining promising research results, the project was completed in 2019 in accordance with the financing agreement. The performed research confirmed the feasibility of constructing a novel semi-technical production line for obtaining dendritic copper powders of different granulations at a production volume of 8 Mg/month. The powders are high quality market products and are obtained in a single process involving the conversion of cable waste, which is otherwise uneconomic to process in a recycling regime. The publication was prepared in accordance with the beneficiary's obligations regarding the dissemination of industrial research findings and in accordance with the agreement on development work co-financing. The research carried out indicates the technological possibilities of recycling difficult-to-recycle cable waste. The process makes it possible to obtain marketable products in a single waste-to-product operation, reconciles economy with environmental protection and meets the objectives of a Circular Economy. The research results bear the characteristics of novelty and, as such, have been used to develop patent claims. In February 2019, the invention was filed with the Polish Patent Office under number P-429083. |
