As demographic growth and climate change effects increase, agriculture intensifies its pressure on the natural ecosystems from which life on Earth depends. In recent years, novel designs and resource-efficient manufacturing methods have been studied to alleviate the impact of food production, many of them incorporating farms into the urban context. However, farming in freshwater bodies remains largely unexplored and constitutes a great opportunity for innovation when land is scarce. Physical requirements for floating farming demand water barrier, solid, inert, and food-grade material with sufficient natural light transmittance, and lightweight, large-scale, complex-shaped components. Therefore, Polyethylene Terephthalate (PET) is presented in this paper as an ideal material for the fabrication of deployable floating farm modules, and Fused Deposition Modeling (FDM) is selected as the most appropriate manufacturing process for the required geometries. Today, recycled polymers in 3D Printing have progressed as a more sustainable feed for small-scale applications. However, there are limited built examples of Additive Manufacturing (AM) using recycled polymers in large-scale real-life applications. This project explores digital designs and fabrication approaches to large-scale manufacturing using PET obtained from single-use bottles to produce empirical prototypes tested in real-life conditions. The research prompted the digital design of a one-meter diameter translucent dome and a flotation platform, their fabrication using large-scale FDM, the assembly of the printed elements, and the monitoring of the farming module performance during operation. The paper covers the state of the art of related 3D printing technologies and their application in food production devices, details the design process of the floating module, explains the selected printing processes and interfacing strategies, and discusses the empirical evidence on the benefits and drawbacks of large-scale AM applied to the cultivation of food. Overall, the research demonstrates the possibilities of 3d Printing using recycled polymers, adding novel insights from a fully-functional project to the incipient body of research on digital manufacturing in food production.

The construction industry remains under immense pressure to reduce its material and climate related impacts. Increasing material demand and reduced building lifetimes have therefore motivated efforts for urban mining in buildings. Even though urban mining has been projected as a crucial measure for improving resource efficiency, its adoption as a practice in the construction industry remains at a very symbolic stage. Upscaling secondary resource recovery and reuse in the construction sector requires further efforts to understand urban mining feasibility from the perspective of project timelines, salvage time, skills and costs. Hence, this study develops an empirical research approach to measure urban mining feasibility and applies it to demolition-ready urban residential buildings stock in Singapore with semi-skilled construction workers. It develops indicators for urban mining feasibility based on planning stages, process change, behavioural practices and reuse-driven economic considerations. Based on urban mining of over 350 building components from 34 categories, results show an average of 1 to 12 min recovery time with an estimated urban mining cost from S$0.8 to S$9 per building component. Further, regulatory requirements for demolition permits can provide sufficient time for urban mining without affecting project timelines. Even though the mining skills of workers seem important, results highlights significant improvement in mining skills based on repeated salvage of specific building components. Results also provide robust evidence of reuse-driven urban mining feasibility in the case under study with significant prospects for embodied carbon savings. Overall, urban mining of buildings can contribute to net-zero targets and climate mitigation efforts with greater multi-stakeholder involvement and market push for reuse in the construction sector.
