Vessel is an intervention at the consumer level that makes reusability a reality. Our fiscally-beneficial, closed-loop product service system (PSS) activates the circular economy to rewrite the operating book on to-go products. Vessel’s health department certified reusable to-go cup service replaces single-use cups to provide a free and convenient alternative. We supply, wash, and distribute stainless steel cups (“Vessels”) for users to check-out through our web-based app from participating food service facilities. Users enjoy their beverage anywhere and have 5 days to return the Vessel to one of our conveniently located kiosks. Our Vessels are tech-enabled allowing: 1. For real-time inventory tracking and distribution and 2. For users to gain personal quantified environmental impact metrics that inspire positive behavior change and continued use of our service. Our system is designed as a contagious model that catalyzes impact; our service is adaptable, transferable, and scalable.
