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.

Auxilium Infrastructure Partners develops, owns, and operates flexible energy assets that help stabilize the electricity grid while creating new revenue streams for industrial sites and asset owners. The electricity system is becoming increasingly volatile as more wind and solar power enter the grid. This creates a growing need for fast, reliable flexibility: assets that can consume, store, or release power when the grid needs support. Today, many industrial sites have unused grid capacity, heat demand, backup systems, or space for batteries, but lack the technical platform, market access, and operational expertise needed to turn that flexibility into revenue. Auxilium solves this by combining physical energy infrastructure with proprietary software. We deploy and operate assets such as battery energy storage systems, electric boilers, load banks, and other controllable loads. Our platform connects these assets to energy markets and ancillary service markets, allowing them to support grid stability, optimize power consumption, and generate income. We handle the full process from site assessment and technical design to installation, operation, market participation, monitoring, and optimization. This gives customers a simple way to monetize their grid connection or energy assets without needing to build their own trading, control, or compliance capabilities. Our mission is to accelerate the green transition by making distributed energy flexibility scalable, investable, and easy to deploy.

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.

We`ve been organising Startup Weekends in Copenhagen for 4 years, educating and inspiring hundreds of people to become entrepreneurs. We were lucky to see it from the first row how #CPHSW helped people get into the entrepreneur mindset and to try new challenges. We always believed that one of strongest forces were the network of people you created during those crazy weekends. This is why we created Startup Weekend Mega: The biggest Startup Weekend ever organised in Europe.  We´re an awesome group of volunteers coming from a wide variety of backgrounds. All of us have their own stories about how we ended up joining the #CPHSW family.  We are proud that we`re 100% voluntarily run organisation and that we created a culture where everybody feels safe to experiment and make their own decisions. And we`re always there to support each other outside Startup Weekends.  We think being part of the organiser family is an excellent opportunity to try out craziest ideas in your field. A playground where we can have a lot of fun and learn a ton. After years of experimentation now we`re organising our biggest event, Startup Weekend Mega, and we would like to involve new people on this journey. If this makes you excited then please feel free to reach out copenhagen@startupweekend.org  or directly at the job posts. Fun guaranteed!;)
