Real-Time LCA is a powerful platform that enables companies to understand, reduce, and document the climate impact of their building projects during design and construction. 🏘️ By automating LCA calculations, it reduces the effort required for impact assessments by 50-90%. Users can perform collaborative, efficient, and accurate Life Cycle Assessments (LCA) that comply with international standards, certification schemes, and regulations. The platform streamlines LCA processes from BIM to reporting, allowing all stakeholders to visualize, track, and document carbon emissions to meet regulations, reported through our standard templates, or leverage your sustainability data in other applications through our API. 🙌

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.

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.

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.
