Plastic waste and single-use packaging is one of the great unsolved problems for our planet. In Denmark, we produce 844KG of household waste annually per person. Most of this packaging is used for food and beverage products and it is an increasingly large environmental challenge. At Cirqle we are driven by our mission to make single-use a thing of the past and make reuse packaging the norm. Reusing packaging reduces the impact, and greatly minimizes the natural resource use of packaging. With our pioneering reuse packaging service and technology platform, we make reuse a reality for companies in the food and beverage industry. We are already breaking new ground with our meal-kit service, but the sky's the limit when it comes to reuse packaging. With partners we cover the full supply chain from packaging production and software development to sanitation and logistics making sustainability the easy choice for our customers.

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.

Our long-range ethanol-powered drones operate fully autonomously and can deliver up to 230kg of critical parts, tools, or supplies to ships, rigs, or remote coastal locations across 2400 km. By replacing helicopters—which are costly, carbon-heavy, and logistically inflexible—we provide a cleaner, safer, and far more efficient solution. GAIA Express enables offshore industries to meet urgent needs in within the hour, instead of within hours, while reducing CO₂ emissions by over 95% per delivery compared to traditional helicopters - based on a full lifecycle assesment. Our scalable platform supports everything from spare parts to medical kits, helping the maritime and energy sectors stay operational and sustainable.
