At Rejoose, we believe traditional business transactions lack transparency when it comes to their environmental impact. In essence, they leave a hidden cost – carbon emissions – unaccounted for. This creates several challenges for companies: Blind spots in sustainability: Without knowing the carbon footprint of each transaction, setting and tracking progress towards emissions reduction goals becomes a guessing game. Informed decision-making hurdles: Sustainable choices often involve trade-offs. Without clear data, prioritizing actions to optimize environmental impact becomes difficult. Stakeholder engagement struggles: Customers and investors demand environmental accountability. Traditional invoicing offers no way to showcase your commitment with concrete data. Compliance concerns: Regulations around carbon reporting are tightening. Ignoring transparency can lead to penalties and missed opportunities. This is where Rejoose e/voice steps in. We seamlessly integrate carbon emission data directly into your invoicing process. Think of it as transforming financial transactions into powerful sustainability statements. Every transaction now carries valuable insights into your environmental footprint, empowering you to: Pinpoint and tackle emission hotspots: Identify areas in your supply chain and operations where emissions are highest, allowing you to prioritize improvement efforts. Tell your sustainability story: Communicate your commitment to a greener future with transparent, data-driven reports that resonate with stakeholders. Make a real difference: Take informed actions that minimize your environmental impact, contributing to a more sustainable future for all. At Rejoose, we believe transparency is key to sustainable business practices. Let e/voice be your guide to unlocking valuable insights and taking concrete steps towards a greener future.

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.

At North ESG, we’re building the AI-powered ESG accounting software for SMEs. 99% of all companies in Europe are small and medium-sized enterprises. They drive our economy - but when it comes to sustainability, they are underserved. ESG reporting is complex, time-consuming, and an administrative hassle. We believe the future of ESG should be about growth - not admin. Our mission is to free up time and strengthen the ESG profile of SMEs as a commercial advantage, so they can stay competitive, win more business, and meet rising demands from customers, regulators, and investors. Our platform automates the entire ESG reporting process using AI - from data collection to emissions calculations and EU-aligned reporting. It integrates with ERP systems and leverages both public and private data sources to generate tailored, commercially viable ESG reports. We’ve already gained strong market traction across industries in Denmark. And with ESG requirements increasingly cascading down from large corporates and financial institutions, we’re solving a growing pain for millions of SMEs across Europe.

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.
