Kaffe Bueno

Kaffe Bueno is a Danish bioscience company based in Copenhagen, we upcycle coffee by-products into active and functional ingredients for cosmetics, nutraceuticals and functional foods. Our vision is to change the world sees coffee - from a caffeinated beverage to a sustainable resource for health and wellbeing. Our mission is to unlock coffee's health and commercial potential by taking advantage of the whole spectrum of its bioactive compounds. Some of the things we do: - Produce KAFFOIL: an active cosmetic ingredient upcycled from coffee grounds. It's used for healthy ageing, hair care, moisturising, and improving the skin barrier. You can find it in over 15 brands worldwide, including NIVEA. KAFFOIL is also used as an ingredient in food & beverage. - Produce KAFFIBRE: upcycled defatted coffee fibre used as an ingredient in cosmetics and food & beverage. - Circular partnerships: we upcycle spent coffee grounds from local businesses in Denmark into toiletries (hand soaps, shampoos, lotions and creams) and have a private label brand for these. - New products coming soon, all derived from molecules from within coffee.

ARIS Robotics

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!

TEGnology

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.

a:gain

We develop, innovate, produce and deliver scalable waste-based building elements and interior products for the professional built environment. The construction industry account for 40% of all waste generated and is the #1 consumer of raw materials globally. The embedded carbon in building materials account for 11% of global carbon emission. At the same time, global floor area is expected to double by 2060. Sustainable building materials will be key to reducing footprint from the construction industry. We need to change the way we build and focus on materials produced from non-virgin materials. We make it possible to accelerate the necessary change towards a reduced use of virgin raw materials in our buildings by developing new earth and climate friendly products and solutions based on waste, biproducts, unused resources, and discarded production. We make it easy for the ones who design and build to choose a waste-based product, for the benefit of the environment, the user and the investor. Our approach is scalable. We are experts in creating valuable upcycled products from scalable sources of waste. We see opportunities, when others see waste. Our know-how drives innovation and product development and shape the products of tomorrow with the waste of today. Together with our trusted production partners, we offer our products at scale to the professional customer with warranties, guaranteed delivery, certifications and documentations. Come join the movement!

Elby

Personal transportation is one of the greatest sources to Co2-emmission and air pollution. The change from a fossil fuel car to an EV is the lowest hanging fruits to decrease this emmission. Before you make this shift, you want to make sure that you can charge your car, which can be challenging if you live in a city, where you depend on a public roll out of EV charging infrastructure, which often lacks behind. This is what we want to change with Elby. Elby's solution enables an ubiquitous roll out on market conditions and at a marginal cost of the known solutions.
