Jonathan Cohen and Jorge Gil have just published a new article in Resources, Conservation & Recycling Advances entitled 'An Entity-Relationship Model of the flow of waste and resources in city-regions: improving knowledge management for the circular economy'. This paper addresses the challenge of organising and standardising information about waste and resources management in city regions. Given the amount and variety of data constantly captured, data models and standards are a crucial element of Industry 4.0. The paper proposes an Entity-Relationship Model to harmonise definitions and integrate information on waste and resources management, helping to formalise the components of the system and their relationships. The proposed data model for the Circular Flow of Waste and Resources enhances traditional waste management perspectives by introducing Circular Economy strategies and spatial variables in the model.
