loop-it is a smart and circular Packaging-as-a-Service. We developed a digital reuse system for take-away packaging to prevent single-use waste. We make take-away financially and environmentally sustainable for our customers and users. The economy is only 9% circular. Packaging loses 95% of the value after one usage and 30.000 paper cups are used every minute worldwide with only 0.25% being recycled. This linear system leads to continuously ordering and throw away cups. This includes the depletion of resources, environmental pollution with increasing costs for waste management and ecological destruction referring to the change of ecosystems. There is a need to transform our throw-away culture. We developed a circular and digital system to prevent single-use waste and costs, benefit the environment and enable returning customers. loop-it stands for circularity, profitability, consumption insights, and convenience. We transform the to-go system by being the interlink of all actors for a sustainable consumption. How loop-it works: 1. Order your food or drink in a loop-it cup or box at any partner location. 2. Enjoy your food or drink anywhere and at any time. 3. Return the loop-it cup or box at any partner location. 4. Next time: collect a new loop-it cup or box at any partner location and you are back at step 2. On our app users can track and see their activity. We offer consumer insights to our partners and convenience for the users. Our cups are 100% recyclable, shatterproof, BPA-free and up to 1000x dishwasher safe. We combine the needs and problems from society, economy and the environment in our user-centred system. loop-it started based on the massive amount of waste from paper cups on campus, in cities and overfilled bins. The ecosystem does not naturally produce waste. Waste is a social construct based on human interventions. We want to transform this linear system into a circular system in a collaborative approach. This is our take on enabling change. We are doers and systems thinkers. We are enthusiastic and committed to shape a better future. With our interdisciplinary skills including Computer Scientists, Mechanical Engineers, Business Designers and Consumer Psychologists, we have the potential and motivation to change the status quo.
