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.

What is RE-ZIP RE-ZIP is a circular packaging concept offering circular packaging to more or less all players in the ecommerce industry. By circulating and hence reusing rather than using single-use packaging (even recycled) we save CO2 even the first time a packaging is reused. It works likes this RE-ZIP delivers the packaging to webshops who offer the sustainable packing solution to their customers at check-out for a minor fee (paid back via reward voucher upon returning the packaging). Upon receipt of the goods the customer folds the RE-ZIP packaging to a return format and return it at a Drop Point. The packaging is returned to the RE-ZIP warehouse for cleaning and re-circulation to the webshops. The RE-ZIP packaging can be circulated up to 10 times, but more importantly the packaging will begin saving CO2 Within the first or second use – depending on the type. RE-ZIP has developed a state-of-the-art backend system supporting the above process and are currently operating in Denmark, UK and Poland. Hence working at RE-ZIP will offer you in-person colleagues in Denmark and remote colleagues in before mentioned countries and more to come. Working at RE-ZIP Working from the Danish RE-ZIP HQ you will find a bunch of nice new co-workers who appreciate to work from the office most days, because the energy we create together is important for us. That does not mean that you have to be here all day every day. You will have flexible working hours to accommodate your daily life. The atmosphere in the office is laid back and rather than working solo on projects and tasks we gather and combine our skills. Send us your application to come join us in our mission to change e-commerce packaging for good.

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.

Fischer Lighting is a sustainable front-runner who has developed a unique circular business model where waste is transformed into new beautiful lamps that make buildings more sustainable and people healthier. In 2023, Fischer Lighting saved more than 53 tons of discarded lamps from being thrown away, and with the concepts ReUse, ReDesign, and ReCreate, unique lighting solutions are created in a beautiful and industrial design that meets all the requirements of a new lighting fixture. In addition to environmental sustainability, social sustainability is also an important part of the concept. Therefore, all the old lamps are separated and assembled by people on the edge of the labor market in Denmark. At the same time, the lamps are equipped with the latest technology, which, among other things, enables circadian lighting, which can stimulate the production of hormones in our body and create better well-being for people in buildings.

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.

ESEBA, a deep tech startup from DTU, transforms low-quality textile waste into MDF boards without binders or formaldehyde. We offer a sustainable, non-toxic alternative to traditional wood-based panels. Textile waste is a massive and growing problem in Europe – less than 1% is recycled into new products, and most ends up incinerated. At the same time, formaldehyde regulations are tightening, and deforestation pressures are increasing demand for alternatives to virgin wood. ESEBA’s mission is to enable local, circular board production through a scalable, plug-and-produce production line for furniture manufacturers.
