Can waste that possesses convenient structural properties be repurposed into modular structural assemblies and thus contribute to a circular economy in the built environment? This is a largely novel idea that is under-explored. A structured and generalized framework is presented to address and evaluate this idea. Validation of the efficacy of the framework is based on functional demonstration for a particularly compelling waste stream opportunity presented by the large number of discarded bicycle frames in many world economies. Key impediments include but are not limited to, efficient solutions to materials disassembly, sorting, structural properties assessment, markets, and re-assembly designs. Detailed analysis of modular structural truss assemblies from bicycle frames helps to demonstrate the solution steps included in the framework. In particular, the functional demonstration of the research concepts validates the feasibility of adaptively reusing bicycle frames into a modular assembly with a maximum load capacity of 3.6 kPa. The methodology presented can be used to add value to specific waste streams, contribute to reducing environmental impacts, and serve as a model for other adaptive reuse applications beyond the structural design context. The findings point to implications for product stewardship, as well as design for disassembly, and support future project development plans for policymakers. Barriers addressed by this research include those related to structural competency, lifecycle optimization, and economic feasibility. This research inspires new ideas to employ waste material for structural designs and encourage circular economy practices.
