GLYON

GLYON is developing a CO₂-powered textile-to-textile recycling technology to help brands, fiber producers, and recyclers solve the growing textile waste crisis with a breakthrough chemical recycling process that turns waste into virgin-quality raw materials for new fibers—without fossil fuels. We address the massive problem of textile waste, a global crisis where over 92 million tonnes of textile waste are discarded each year—most of it ending up in landfills or incinerated. This contributes to major pollution issues but also forces the textile industry to continue its dependence on virgin fossil-based materials. Our solution targets fiber producers, brands, and recyclers who need circular raw material solutions. Our CO₂-based chemical recycling process breaks down polyester textiles into building blocks and leaves other fibers like cotton intact. Both PET building blocks and cotton can be used to produce new, high-quality fibers without the need for virgin oil and reducing water consumption and CO₂ emissions.

TEGnology

With a core technology of thermal energy harvesting, TEGnology works on smart power supply solutions for future IoT devices, which don't rely on batteries or cables. It opens opporutnities for generating more data, making more precise moniroting, or installing sensor in the places difficult to reach. Digital transition and industrial automantion sill based on installing a large number of wireless sensor nodes, most of which are currently powered by batteries. Despite the relatively low cost of batteries, the enevitable man-powered involved in maintaining the keeping track of batteries might be problematic, not to mention batteries pollutes. Thermal energy harvesting converts temperature gradience directly into electricity. No moving parts or chemical reactions are involved. The lifetime of thermal generator is therefore typically decades. During the entire lifetime, more energy can be provided than any type of batteries. All materials used in TEGnology’s thermal energy harvesters are abundant and environmentally-friendly. The manufacture method is compatible with existing industrial standard. It makes up-scaling of production relatively straightforward.

United Nations Youth Association(UNYA) Denmark

UNYA Copenhagen is a volunteer-driven youth organization dedicated to empowering young people to engage with global challenges through the lens of the United Nations’ values and the Sustainable Development Goals. We create an inclusive platform where students and young professionals can learn, collaborate, and take action on issues like climate change, social inequality, peacebuilding, and innovation. We are addressing a clear and growing problem i.e. the disconnect between youth and global institutions. Many young people in Denmark care deeply about sustainability and justice but find it difficult to access meaningful opportunities to participate in international dialogue or contribute to real-world impact. This gap leaves motivated individuals without a channel to apply their energy, creativity, and ideas, while institutions miss out on fresh perspectives and engagement from the very generation that will inherit the future. UNYA Copenhagen bridges this divide by turning global ideals into local action. We organize interactive events, workshops, and panel discussions that make complex global topics accessible and relevant. Our activities are co-created by volunteers from diverse academic and cultural backgrounds who bring their own insights to the table. Through collaboration with universities, NGOs, and public institutions, we connect youth directly with experts and decision-makers, fostering a sense of shared responsibility and agency. What makes UNYA Copenhagen unique is our grassroots approach. We are not just an organization — we are a community that thrives on collective energy and creativity. Every project is designed by young people for young people, ensuring authenticity, inclusivity, and long-term motivation. Our strength lies in our diversity and the genuine commitment of our volunteers, who bring the UN’s global mission to life in a way that feels personal and actionable. The motivation behind UNYA Copenhagen is simple: we believe that youth engagement should not be limited to classrooms or conferences but should become a lived experience. We started this initiative because we wanted to make international dialogue tangible, local, and inspiring. Our team members share a passion for learning, community-building, and positive change — values that drive us to dedicate our time to building something meaningful together. Today, UNYA Copenhagen continues to grow as a platform where ideas turn into impact. We are seeking motivated individuals who want to gain experience in leadership, communication, and project management while contributing to a global cause. By joining The Hub’s Community Program, we hope to reach more passionate volunteers who want to be part of a dynamic network that connects Copenhagen’s youth with the world.

Energy Machines

We're on a mission to revolutionize the way energy is handled in buildings. Energy Machines™ is a leader in the design, implementation, and operation of integrated energy systems for buildings. Buildings are a growing climate problem, accounting for over 28% of global CO2 emissions. We are working to transform them into climate solutions. By combining proven best-of-breed hardware with purpose-built software and simulation platforms, Energy Machines enables buildings to operate as “energy machines” or fully integrated systems that generate, store, and reuse their own energy. In order to revolutionize the way buildings are managed. We are developing a next generation computing platform. This platform will leverage cloud, IoT technologies and modern electronics to upgrade existing industrial systems. We envision a future in which buildings accelerate the world’s transition to sustainable energy.
