Portland’s festivals piloted standardized reusable cups with onsite washing and well-marked return bins, slashing event litter and cleanup costs. Vendors reported faster service once customers recognized the system. Deposits were small, refunds instant, and signage playful yet clear. The city’s role was coordination and permitting flexibility, allowing operators to test station layouts. The result: smiling volunteers, lighter trash bags, and attendees who began expecting reuse at concerts, not just farmers’ markets.
Seoul has experimented with reusable containers for food delivery, integrating returns into popular apps and curbside kiosks. Couriers swap sealed containers at pickup, then customers scan for deposit refunds. Government incentives helped restaurants enroll, while strict hygiene protocols reassured diners. Early data showed high satisfaction when return locations were dense. By blending digital convenience with real-world infrastructure, the program reframed takeout from a guilty pleasure into a cleaner, smarter routine across bustling neighborhoods.
