DISIE - Danish Institute for Sustainable Innovation and Entrepreneurship

DISIE support and scale sustainable entrepreneurs and their business solutions by developing and providing online and offline tools, action-based knowledge and networks across Denmark. We are at a tipping point within history, where we have to choose between ‘business as usual’ or a sustainable future. Our society calls for new knowledge and new solutions, and the key to this is found in the new generation of entrepreneurs. At DISIE we know how to grow, connect and support sustainable and social entrepreneurs with the ecosystem that surrounds them. Our headquarter is in Copenhagen (Enghavevej 80C) and we have a co-working office hub in Aarhus C (Grønnegade 56).

Responsibly

Responsibly is a sustainability tech start-up with vision of making every purchase in the world responsible 🌍 There's no bigger problem out there than the climate, and procurement represents a big part of the solution - when purchase decisions are made on the background of responsible data like CO2 footprint, suppliers have a huge incentive to change. However, procurement is becoming overloaded with complexity. Different frameworks, different data sources, different coverage, making it difficult to make purchase decisions to improve your responsibility profile and scope 3 emissions. At Responsibly, we're trying to solve this issue by using leading technologies and data science, to build a supplier data platform that makes it easier to source responsibly. We're founded by two serial entrepreneurs with previous successes like Dixa and Ofload, and have received pre-seed funding from some of Europe's top VCs and angels. We're now building a top-tier team to tackle this big thing called climate, and have fun while we're doing it 🤘

Legacy

Hi, we’re Legacy! We’re on a mission to make sustainability actionable, and we’re looking for passionate talent to help us accelerate the green transition. Founded in Copenhagen in 2019, Legacy is a purpose-driven start-up helping commercial real estate owners calculate their CO2 emissions through digitalisation, automation, and user-friendly design. As the real estate business is a dirty one - accountable for almost 18% of global emissions alone - we believe it represents an exciting opportunity to create real impact. That’s why we’ve built a platform helping real estate companies turn good intentions into tangible action based on reliable and transparent data. Things are moving fast, and we need help to keep up. So tell us about yourself, what you’re passionate about and how your values align with our mission. We can’t wait to hear from you!

Trebo

Trebo is a cleantech startup that develops and manufactures a novel fluid-mechanical based plastic sorting technology. The sorting technology enables the plastic industry to sort large-scale plastic-type mixtures and transform the industry’s production waste into valuable resources. The Procurement costs on virgin materials are reduced and the environmental impact from incinerating or dumping plastic waste is eliminated. The annual global production of plastic has in 2019 exceeded more than 300,000,000,000 kg and even though the majority of plastic waste is suited for recycling purposes, more than 90% of the global production of plastic is either incinerated, deposited or dumped in nature. As the production of one kilogram of virgin plastic on average requires three kilograms of natural oil, the plastic industry is a global large-scale consumer of fossil fuels and therefore an important intrant in the green and sustainable changeover of the industry. Due to the wide palette of applications and physical characteristics of plastics, many end-user plastic products consist of one or more different types of plastic. As the quality and application performance of mixed plastic is decreased critically compared to the pure counterpart, plastic mixes are often considered as waste and therefore incinerated or sold to a price significantly lower than the price of the virgin plastic. Industrial waste streams of mixed plastic constitute approximately 60% of the total plastic waste stream. We believe it is critical to develop technologies that effectively sorts and restores the value and physical properties of the virgin plastic. At Trebo, we are environmentalists and our vision is to make the global plastic industry more sustainable and renewable. We hope that you will join us on our adventure.

Normative

Our Mission: Normative is here to make known and reduce the sustainability impact of all economic activities on the planet. We provide science-based carbon accounting software and tailored advice from net zero experts, enabling companies to reduce their carbon footprints. Our Story: Normative is rooted in climate research. In 2013, co-founder Kristian Rönn was working at Oxford University, simulating the consequences of climate change. The results showed that global warming would cause extreme human suffering, motivating Kristian to leave academia and take action. He joined forces with Adam Wamai Egesa and Robin Undall-Behrend, and in 2014 the world’s first carbon accounting engine was born to help humanity achieve net zero emissions and reverse the trajectory of climate change. We now have offices in Stockholm, Copenhagen, and London, and are actively hiring talent to join the mission. Today, companies from around the world trust our carbon accounting engine to help them reduce their carbon footprint. We partner with leading climate change organisations including the UN, to deliver actionable sustainability intelligence and have received a grant from Google. We are backed by some of the world’s most significant climate investors, and are the official software provider for the UN-backed SME Climate Hub initiative through which thousands of small businesses have committed to net zero. Our Team: We are a global team working to solve a global problem. We’re headquartered in Stockholm, with offices in Copenhagen and London as well as remote team members located all over the world. We have spoken at the World Economic Forum, consulted the European Commission, and worked with the United Nations to develop a new standard for emissions accounting. We come from many walks of life, but we’re united in one mission: to help humanity achieve net zero emissions. Every employee at Normative plays a valuable role in reducing business carbon emissions.

THE UPCYCL

THE UPCYCL connects your industrial waste streams with your neighbors supply chain. We make it possible to reduce our amounts of industrial waste, by turning waste material streams into business opportunities. Our material database displays leftover materials from production, giving developers easy access to reusable materials, also called "New Waste". Hereby, achieving a significantly lower CO₂ footprint than with virgin materials. When circulating New Waste materials with the THE UPCYCL, we also offer to monitor CO₂ savings. We work to accelerate the use of circular materials, worldwide. Because Waste is Everyone's Business!
