Circular Campus is a digital platform connected to smart lockers where students can hand over and pick up items. When a student leaves campus, they place items such as furniture, books, bikes, or kitchenware in a locker and register them through the app. Incoming students can then browse available items, choose what they need, and unlock the locker via the app to collect them. Items can be rented, bought at a low price, or donated for free. This system creates a simple and sustainable way for students to exchange goods directly on campus.

The Problem When students arrive on campus, they often buy furniture, bikes, books, and kitchenware. At the end of their stay, especially for exchange or Erasmus students, many of these items are thrown away. This creates high costs for students, significant waste, and unnecessary CO₂ emissions. The Solution Circular Campus provides a digital platform linked to smart lockers that enables students to exchange items easily. Outgoing students place their items in a locker and register them in the app. Incoming students can browse what’s available, rent, buy affordably, or collect donations, and then unlock the locker via the app. This creates a simple, community-driven system that reduces waste, saves money, and makes campus life more sustainable.
