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.

ARIS Robotics was founded by a shared vision: to steer the world towards a greener future. One of the critical challenges in the green transition is how we manage our resources and waste. Today’s processes are highly linear: raw materials are extracted, processed into products, used a few times, and then discarded—either incinerated or buried in landfills. We aim to change that. At ARIS, our ultimate goal is to create a world without waste. This means transforming linear processes into circular ones. The first step towards effective recycling is good sorting. We develop scalable and automated solutions using deep learning to recognize and sort waste efficiently. Currently, we are serving our beachhead market—public recycling centers. Here, we assist visitors in correctly sorting their waste, extending the lifespan of materials and reducing the need to extract more raw materials from our limited planet. We are always on the lookout for passionate individuals to join our mission. Keep an eye on our open positions, follow us on LinkedIn, or feel free to send us a motivated application. Let’s create a greener future together!

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.
