Our planet is overheating, biodiversity is reducing rapidly, and natural resources are being depleted. With 40% of global energy-related CO2 emissions and 30% of global landfill waste, construction plays a significant role in our planetary crisis and is by far the most polluting sector. We need to do things differently. Stykka takes you on a journey toward a future where the construction industry is part of the solution rather than the problem. We’ve set out to develop scalable solutions that enable like-minded developers and investors to build more sustainable, efficient and profitable. With Stykka we enable forward-thinking developers to build sustainably and be part of the solution rather than the problem. We use cutting edge technology like 3D scanning, digital fabrication, and distributed manufacturing to create new experiences and amazing, sustainable products for an array of clients.   With Stykka we aim to leave a positive impact on our planet and solve one of the biggest problems of our time, and we want you to be part of this journey.

At Cellugy, we’re passionate about creating innovative solutions for one of the most pressing challenges of the 21st century: plastic pollution. Our product, EcoFLEXY, is a 100% natural bio-cellulose material produced by the fermentation of surplus sugar with specific microorganisms. The objective is to replace fosil-based plastics and products in a wide range of applications, from packaging to chemicals.

Many people are talking about the smart grid and how we can reach 100% sustainable energy, and avoid global warming getting out of hand, by intelligently balancing the consumption so it fits with the electricity production. At True Energy we're already doing it! True Energy offers a smart charging app to our end users so they can register their car or charger and have it start or stop charging based on the hour of day and the electricity price, so the user optimizes their charging to be cheapest. The service is free of charge for the end user because they participate in our flexibility pool where the power companies can buy offsetting of the consumption if the grid is overloaded or production is expensive. We use Google Workspace, GitLab as code repo, Jira for our agile project management, and Slack for chat. We have a policy of 100% line coverage for unit tests, and want to support continuous delivery. We focus on collaboration and an open, inclusive work environment. Our team is multinational, and the working language is English, so full proficiency is required.. We have team members in several time zones.

In the European Union alone, more than 1.5 million paint buckets are discarded daily, constituting a disposal of 340 tons of single-use plastic that is incinerated each day. Starting from early 2023 (2025 in Denmark and Slovenia), manufacturers are obligated to cover the disposal costs of their packaging based on sustainability criteria. In Denmark, this translates to an estimated 15% fee on paint buckets. Furthermore, the conventional round shape of packaging has proven suboptimal for logistics and transportation. Beyond its environmental impact, the traditional paint bucket poses challenges for professional painters. These challenges encompass ergonomic issues during handling, such as the strain of lifting two buckets simultaneously, which exceeds recommended weight limits according to the Working Environment Authority. Painters also find themselves in awkward positions when pouring paint into a roller bucket for wall application. The demanding physical nature of the painting profession in Denmark results in accelerated fatigue and early retirement for painters. Additionally, issues like lid leakage due to dried paint and the use of fragile, porous plastic contribute to unexpected spills, particularly during abrupt vehicle stops. Our innovative solution involves a cardboard box housing two patent-pending plastic bags, each containing 5 liters of paint. This packaging not only enhances the workflow for professional painters but also reduces costs and lowers carbon dioxide equivalent (CO2e) emissions by approximately 65% per unit. The box's design facilitates easy and ergonomic transportation, allowing for a 45% increase in units per pallet. The box is opened, and one of the bags is inserted into a standard roller bucket used by painters. The bag effortlessly opens and seamlessly fits into the roller bucket, wrapping around the edges, and enabling the painter to begin work promptly. This functionality is made possible through an innovative patented design and specific plastic welding techniques.

Vi vil gøre Danmark grønnere! Bliv Grøn Nu er en nystartet virksomhed (under Borch-Andersen ApS) som hjælper firmaer med at blive CO2-neutrale. Vi beregner CO2 fodaftryk udfra de aktiviteter der er i firmaer, giver dem en rapport efter Green House Gas Corporate Protocol og Value Chain Protocol og hjælper dem derefter med at lave de rigtige grønne investeringer, der reelt opfanger lige så meget CO2 som er i deres fodaftryk - ikke bare god samvittighed, men reel ændring. Vi leder efter nye kollegaer på vores rejse imod at gøre Danmark grønnere.

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!

Girls' education is an incredibly powerful climate solution due to its stong relationship with child marriage prevention and subsequent delayed motherhood; impacting population growth and lowering consumption-based emissions. 130 million girls in the world's poorest and most climate-vulnerable communities are effectively excluded from education due to poverty. Humanitarian organizations in low-income countries constantly struggle to fundraise and are never able to fully meet the needs of the most marginalized. SoGreen is a startup with a big heart and an even bigger ambition: A world where all girls realise their right to education and climate justice is placed at the heart of all climate action. In collaboration with leading scientists at renowned European research institutions in the field of demography and climate science,* SoGreen has developed a methodology to quantify the climate impact of girls' education in tonnes CO2-equivalent avoided. This allows for the generation of carbon credits (1 ton = 1 carbon credit) which can be sold on the international carbon market to channel climate finance to girls' education. In partnership with FAWEZA, a leading pan-African NGO focusing on girls' education, SoGreen's pilot project is being implemented in Zambia. Over the coming 5 years, the project will ensure a full secondary education for 180 marginalized girls. All carbon credits generated by the project have been sold ex ante to over 30 companies that have ambitious sustainability strategies, which allow for the use of carbon credits in addition to reducing their own emissions. SoGreen aims to be the provider of the worlds most popular carbon credits within the next 5 years; resulting in a powerful reduction in emissions and a massive increase in educational attainment - a basic human right. *International Institute for Applied Systems Analysis (IIASA) in Austria, Potsdam Institute for Climate Impact Research (PIK) in Germany, and The Wittgenstein Centre for Demography and Global Human Capital (WIC) in Austria.

We are passionate reinventing how homeowners and skilled builders find each other. In the past, if you needed building work done on your home, you would have to rely on word-of-mouth or hope that someone you know could recommend a good builder. 3byggetilbud.dk changed all that by creating a marketplace where homeowners can post their jobs and then the platform matches the best three builders for that specific job. This means that you can be sure to find a builder who is not only reputable but also has the skills and experience to do the job well. Our commitment to innovation has made us the market leader for Danish homeowners and builders alike.

Nabo Farm er et urbant landbrug drevet efter bæredygtige principper. Vi dyrker dild, koriander, fennikel, tallerkensmækker og andet mikrogrønt, som vi leverer til en kundekreds bestående af lokale restauranter og kantiner. Vores kunder er både kvalitets- og miljøbevidste. De kan se værdien i at modtage deres bestilling, senest to timer efter den er høstet. Hverken smag eller næringsværdi går tabt under leveringen, som selvfølgelig foregår med cykelbud. Sådan trækker vi i fællesskab fødevareindustrien i en sundere og mere bæredygtig retning. Det er det, vi forstår ved godt naboskab. Afgrøderne er naturligvis fri for sprøjtegift og genmodifikationer. Deres næringskilder er en nøje udvalgt sammensætning af ilt, mineraler, varme, vand og god musik. Tilsammen har vi mere end 15 år i tech-branchen på bagen. Den erfaring har vi brugt til at udvikle en software, som kan styre planternes omgivelser ned til mindste detalje. Resultatet er sundt og velsmagende bladgrønt. Det synes vi alle har ret til, ligesom enhver by har ret til en Nabo Farm.
