Circular Economy (CE) and the potential of reusing and recycling the products after the end of their life, becomes imperative for environmental, economic and social reasons. Especially during the 4th Industrial Revolution that is taking place nowadays, an increasing number of out-of-date equipment has to be replaced, which constitutes a chance and necessity to be reused, through recycling, redesigning and remanufacturing. The paper presents proof-of-concept studies regarding upcycling of obsolete and outdated equipment into novel test rigs mainly addressing research activities. Three such case studies are presented, namely the upcycling of an injection moulding machine into a modular test bench for power hydraulic components, the upcycling of scrap components into a hybrid hydraulic/ ICE powertrain rig and the functional augmentation of a gear roll tester to accommodate single and double flank tests. Significant savings in cost, raw materials and time are demonstrated in all cases and adherence to the CE objectives are observed.
