I'm curious about the sanitary sleeve required to make this system work. What material is that made of and is it too compostable? Additionally, has any market testing/focus grouping been performed to understand the necessity of the points/reward system for consumer. My inclination would be that consumers would be more than willing to support a reuse program, but that customers (ie participating businesses) would be the hindrance in deploying this system, as they would have invest additional capital to launch the program, pay for a compost transportation service, and potentially dedicate land to a re-use garden. Since there's no other benefit for participating firms above and beyond being green (except for positive PR), you might try to come up with more fiscal incentives for participating firms and let the altruism of the consumers be your adoption/growth engine.
