Digitally enabled circular economy with Industry 4.0 Requirement analysis and implementation vision

Implementing digital circular economy use cases puts high requirements to lifecycle information of assets, e.g. devices, and to the infrastructure storing and serving this information. We review the requirements from circular economy and compare them with current developments of Industry 4.0. We observe that most gaps regarding circular economy requirements relate to the infrastructure. To close these gaps, we present a vision called Long-Term Storage Digital Twin (LTS Digital Twin) and sketch its use for disassembly data and carbon footprint estimation use cases.
