Circular economy
The circular economy aims to maximize the efficiency of material and energy use within a continuous loop in the built environment, reducing the environmental footprint of economic activities by minimizing waste and promoting the reuse, repair, remanufacturing, and recycling of products and materials. This research thrust aims to assess the environmental sustainability of different resource recovery technologies (such as biopolymer, energy, and nutrients) from wastewater and other waste streams.
