NitroVolt

NitroVolt is decarbonizing nitrogen-based fertilizer production and making the agricultural sector more resilient with a novel production process. Commercial ammonia production supports 40-50% of the agricultural industry as a nitrogen-based fertilizer. But current ammonia production is not sustainable, releasing over 1% of global greenhouse gas emissions during production facilities and further emissions during transportation to the end user, farmers. NitroVolt offers a local ammonia production solution that gives farmers the ability to produce their own nitrogen-based fertilizer. The only inputs required by NitroVolt’s container-sized systems are air, water, and electricity, enabling production of sustainable ammonia directly at farms. NitroVolt’s patented electrochemical Nitrolyzer unit can make ammonia on-demand with intermittent renewable energy sources. With their technology, NitroVolt aims to decarbonize nitrogen-based fertilizer production one farm at a time, cut the logistic costs of distributing fertilizer, and make the agricultural sector more resilient to external factors.

Swan Neck Bio

Swan Neck Bio partners with food and biotech companies of any size to scale, commercialize, and deploy their microorganisms. Our vision is a world where there are no constraints to progress for the biosolutions urgently needed by a growing population. Today, food and biotech companies with promising solutions looking to scale are held back by a slow testing phase and huge capital outlays. These unnecessary constraints cause too many businesses to fail before their time. We partner with you to help you trial, validate, and scale your microorganism from lab to 1,000L. This dramatically derisks your scaling process and accelerates your time-to-market. And its 10-100 times cheaper than existing solutions.

Climaider

Climaider is a rapidly growing startup, enabling Small and Medium sized Enterprises to measure and report their ESG and to take real climate action. ESG reporting is becoming a necessity if you want to stay competitive, retain your employees, get funding or financing and win customers and jobs. But SMEs have been left behind in a reporting environment that has been shaped first and foremost to accomodate very Large enterprises - leaving SMEs with an extremely complicated and tedious reporting job that often falls on employees or owners with a 1000 other responsibilities too. We help and guide SMEs, automate +95% of the work and instill in them the confidence that they can do this and that they have done it the right way. Our goal is to remove the headache of reporting, leaving room to focus on what is actually important: Reducing the carbon footprint of your company. We're set on becoming THE solution for SMEs all over Europe, making reporting easy, comparable and actionable. Join us!

Klimate

We are devoted to accelerating the development and adoption of technologies that can help fight climate change by actively removing CO2 from the atmosphere. The challenge We are emitting 50 Gigatons of CO2 every year, and that needs to be reduced by at least 80%. However, that still leaves 10 Gigatons of CO2, and we need to get all the way to zero. Trees are great, but we need many more solutions as well if we are to get to zero. Currently, most of these are way too expensive (and limited in capacity) for companies to use. We've developed a platform that combines methods and makes it available to every company that wants to compensate their emissions. We work with cutting edge technologies, including Direct Air Capture, Bio char, Bio oil etc.

Kaffe Bueno

Kaffe Bueno is a Danish bioscience company based in Copenhagen, we upcycle coffee by-products into active and functional ingredients for cosmetics, nutraceuticals and functional foods. Our vision is to change the world sees coffee - from a caffeinated beverage to a sustainable resource for health and wellbeing. Our mission is to unlock coffee's health and commercial potential by taking advantage of the whole spectrum of its bioactive compounds. Some of the things we do: - Produce KAFFOIL: an active cosmetic ingredient upcycled from coffee grounds. It's used for healthy ageing, hair care, moisturising, and improving the skin barrier. You can find it in over 15 brands worldwide, including NIVEA. KAFFOIL is also used as an ingredient in food & beverage. - Produce KAFFIBRE: upcycled defatted coffee fibre used as an ingredient in cosmetics and food & beverage. - Circular partnerships: we upcycle spent coffee grounds from local businesses in Denmark into toiletries (hand soaps, shampoos, lotions and creams) and have a private label brand for these. - New products coming soon, all derived from molecules from within coffee.

KiteX

At KiteX, we're revolutionising energy with innovative wind turbines inspired by kites. Our mission? To make wind turbines that use significantly less material, offering a cost-effective and sustainable alternative to traditional turbines. Our journey began by envisioning wind turbines that combine the efficiency of kites and autonomy of drones. On this path we found an hybrid design with guy wire supported tower and blades could achieve almost the same material savings, but without any of the disadvantages. Our unique approach centres on patience, refining technology step by step, and focusing on sustainable solutions. We're scaling up production of the groundbreaking Wind Catcher, a portable off-grid turbine, while designing a larger, grid-connected successor. As we grow, we're seeking exceptional team members in marketing, customer support, technical, and electrical engineering. KiteX isn't just a workplace; it's an opportunity to drive clean energy and make history. Join us in shaping a sustainable future. Contact us through the hub or at info@kitex.tech to be part of something extraordinary.

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.
