Overview

• UBC’s prototype went live at the Botanical Garden on Sept. 26 with real users participating in a six-week field test.
• The system diverts liquids to a holding tank while solids enter a mycelium-lined compartment where fungi and microbes convert waste into compost.
• Project lab tests reported by the team found the mycelium liners removed more than 90% of odor-causing compounds.
• If performance is validated, researchers estimate annual outputs of about 600 liters of compost and 2,000 liters of liquid fertilizer.
• The prefabricated, wheelchair-accessible unit is designed for just four maintenance visits a year, offering a potential alternative to chemical toilets that need frequent servicing.
