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.

Maker is a member-based non-profit association founded in 2015 as a platform for the maker movement in Denmark and the Nordics. Since then, we've evolved from a traditional makerspace into an open lab and community central for physical entrepreneurs, startups and independent creatives. We develop, share and learn together with our members and across projects in the EU, in Denmark and in the Baltic Sea Region. Together with research institutions, companies, makerspaces and governments, we focus on sustainability and physical entrepreneurship; from open-source hardware to distributed design, aiming to transition makerspaces into circular spaces and develop sustainable practices for recycling materials, local production, and more.

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.

Trebo is a cleantech startup that develops and manufactures a novel fluid-mechanical based plastic sorting technology. The sorting technology enables the plastic industry to sort large-scale plastic-type mixtures and transform the industry’s production waste into valuable resources. The Procurement costs on virgin materials are reduced and the environmental impact from incinerating or dumping plastic waste is eliminated. The annual global production of plastic has in 2019 exceeded more than 300,000,000,000 kg and even though the majority of plastic waste is suited for recycling purposes, more than 90% of the global production of plastic is either incinerated, deposited or dumped in nature. As the production of one kilogram of virgin plastic on average requires three kilograms of natural oil, the plastic industry is a global large-scale consumer of fossil fuels and therefore an important intrant in the green and sustainable changeover of the industry. Due to the wide palette of applications and physical characteristics of plastics, many end-user plastic products consist of one or more different types of plastic. As the quality and application performance of mixed plastic is decreased critically compared to the pure counterpart, plastic mixes are often considered as waste and therefore incinerated or sold to a price significantly lower than the price of the virgin plastic. Industrial waste streams of mixed plastic constitute approximately 60% of the total plastic waste stream. We believe it is critical to develop technologies that effectively sorts and restores the value and physical properties of the virgin plastic. At Trebo, we are environmentalists and our vision is to make the global plastic industry more sustainable and renewable. We hope that you will join us on our adventure.

Incremental Maritime is developing a digital compliance solution that helps shipowners and operators navigate complex decarbonization regulations; transforming compliance into lower emissions and higher margins. Our deep regulatory expertise, data-driven models, and hands-on client support are what set us apart. Global shipping faces an accelerating tide of climate regulation, from the IMO’s GHG Fuel Intensity targets to FuelEU Maritime and EU ETS. These rules impact everything: fuel costs, asset values, and day-to-day operations. Yet most market players lack the tools and insights to respond; let alone turn compliance into an advantage. This leaves shipowners and operators asking: - What decarbonization investments make financial sense? - How do I reduce risk and avoid penalties? - Can I stay compliant across multiple regimes without extra complexity? - Without smart tools, these questions are hard to answer - and costly to get wrong. Our solution has two core parts: Advisory with immediate impact: We help clients assess regulatory costs, model emissions, evaluate investment cases, and support decision-making from planning to operations. A digital compliance agent (in development): Built on real client work, this tool will combine - Real-time emissions tracking - Cross-jurisdictional compliance logic - Commercial impact analysis - Support from pre-fixture to post-voyage We’re building the go-to compliance engine for modern shipping: one that simplifies decisions, protects margins, and scales with regulation. We launched Incremental Maritime because we saw a blind spot: climate regulation was outpacing the industry’s ability to respond and the result was confusion, cost, and missed opportunity. With experience spanning maritime operations and regulatory systems, we knew we could help. We believe that smarter compliance is not a burden, it’s a pathway to performance. We're here to equip shipping with the tools to decarbonize profitably, one fixture, one voyage, one regulation at a time.
