Site Resource Inventories – a Missing Link in the Circular City’s Information Flow

Abstract A circular city builds upon the principles of circular economy, which key concepts of reduce, reuse, recycle , and recover lead to a coupling of resources: products and by-products of one production process become the input of another one, often in local vicinity. However, sources, types and available quantities of underutilised resources in cities…

Sourcing Energy from Waste in the Circular City: Integrated Anaerobic Digestion toward long term Decarbonization

Abstract Energy use within buildings contributes to nearly a third of carbon emissions in the United States (Zhang et al. 2019, EPA). Meanwhile, between 30-40% of food in the U.S. is wasted and generates carbon emissions equivalent to that of 37 million cars yearly (UN FAO). Long term decarbonization strategies within the built environment can…
