Resilient Urban Food Systems

DumoLabPennPraxis, and Penn Farm have partnered as part of the Environmental Innovation’s Initiative’s Resilience Urban Food Systems research community to prototype an outdoor classroom constructed from zero-waste materials. Aiming to demonstrate the feasibility of sustainable building techniques, the prototypes developed on-site will originate from diverse types of waste, including plant matter, landscaping debris, and food. 

Led by Ellen Neises, executive director of PennPraxis, a team of interdisciplinary experts and students will transform waste from Penn Farm, Penn Dining, and Penn Urban Parks into valuable building materials for an outdoor classroom. Beyond leveraging the experiential learning opportunity of the urban farm on campus, this research community addresses the problem of increasing landfill methane emissions by diverting waste from landfills and repurposing it to produce low energy, emission, and cost buildings.

BioCladding from Campus Plant Waste

Six teams collaborated with DumoLabPennFarm and PennPraxis by developing bio-based composites to provide cladding and furniture for a much needed outdoor classroom on the farm grounds, and with a wooden frame skeleton to be completed by Praxis by end of Spring 2026. Students collected inedible crop waste from seasonal sorghum, sweet peas, eggplant and okra at PennFarm and transformed it at DumoLab by drying, grinding, mixing with sustainable binders, digitally manufacturing water-based blends using 2.5D and 3D printing, molding and casting, and hybrid technologies, as well as devising post-processing techniques of site-specific environmental adaptation and durability. Outcomes comprise tables, stools, shingles, panels, air chambers, and bio-receptive tiles, and will be naturally weathered and monitored over Spring at the PennFarm to study their performance in outdoor and semi-outdoor conditions to later serve the Farm's classroom building cladding by Spring-Summer 2026.
