kleen hub ApS

Kleen Hub is a Copenhagen-based circular tech company building Tap & Reuse™ — a frictionless reuse system that makes reusable packaging work at scale. Our platform combines simple hardware with a lightweight software layer to enable fast, reliable reuse without the usual barriers: no app, no user registration, and no deposit handling required. We help venues and operators (cafés, campuses, stadiums, airports, corporate sites and more) replace single-use packaging with reusable cups and containers through an operationally simple setup. Tap & Reuse™ supports multiple return flows (smart return stations, return bins, handheld scanning and washing-site verification), delivers high return rates in closed and semi-closed environments, and provides clear reporting for operations and ESG. Kleen Hub works with leading partners and distributors across Europe and has deployed systems in high-volume environments, proving that reuse can be convenient for users and manageable for staff. Our mission is to remove friction from reuse and accelerate the transition away from single-use packaging — by making reuse as easy as tapping a card.

Elby

Personal transportation is one of the greatest sources to Co2-emmission and air pollution. The change from a fossil fuel car to an EV is the lowest hanging fruits to decrease this emmission. Before you make this shift, you want to make sure that you can charge your car, which can be challenging if you live in a city, where you depend on a public roll out of EV charging infrastructure, which often lacks behind. This is what we want to change with Elby. Elby's solution enables an ubiquitous roll out on market conditions and at a marginal cost of the known solutions.
