Fischer Lighting is a sustainable front-runner who has developed a unique circular business model where waste is transformed into new beautiful lamps that make buildings more sustainable and people healthier. In 2023, Fischer Lighting saved more than 53 tons of discarded lamps from being thrown away, and with the concepts ReUse, ReDesign, and ReCreate, unique lighting solutions are created in a beautiful and industrial design that meets all the requirements of a new lighting fixture. In addition to environmental sustainability, social sustainability is also an important part of the concept. Therefore, all the old lamps are separated and assembled by people on the edge of the labor market in Denmark. At the same time, the lamps are equipped with the latest technology, which, among other things, enables circadian lighting, which can stimulate the production of hormones in our body and create better well-being for people in buildings.

Kleen Hub is a Copenhagen-based circular tech company building Tap & Reuse™ — a frictionless reuse system that makes reusable packaging work at scale. Our platform combines simple hardware with a lightweight software layer to enable fast, reliable reuse without the usual barriers: no app, no user registration, and no deposit handling required. We help venues and operators (cafés, campuses, stadiums, airports, corporate sites and more) replace single-use packaging with reusable cups and containers through an operationally simple setup. Tap & Reuse™ supports multiple return flows (smart return stations, return bins, handheld scanning and washing-site verification), delivers high return rates in closed and semi-closed environments, and provides clear reporting for operations and ESG. Kleen Hub works with leading partners and distributors across Europe and has deployed systems in high-volume environments, proving that reuse can be convenient for users and manageable for staff. Our mission is to remove friction from reuse and accelerate the transition away from single-use packaging — by making reuse as easy as tapping a card.

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.

Os Om Havet er en frivillig organisation, der ønsker at sætte fokus på forurening af verdenshavene. Det er et stigende problem for de marine økosystemer. Omkring 70 procent af al affald, der ender i havet, synker til bunds. Her kan det have store konsekvenser for havmiljøet og er samtidig utilgængeligt for traditionelle oprydningsmetoder. Os Om Havet holder derfor arrangementer, hvor dykkere og andre ildsjæle fra hele Danmark samles og i fællesskab rydder op både over, under og i havet. Vi tror, at en god oplevelse i naturen kan skabe motivation og engagement til at handle på nogle af de store udfordringer, miljøet står overfor. Os Om Havet er mere end svømmefødder og iltflasker. Med foredrag og skoleforløb ønsker vi at udbrede budskabet og gå sammen om at få skabt en bæredygtig fremtid, hvor mennesket og naturen i højere grad forenes. Kom og bliv en del af fællesskabet! Hvis man gerne vil sikre sig, at Os Om Havet fortsætter kampen mod forurening af vores havmiljø, kan man blive Os Om Havet støttemedlem for 200kr årligt. Der er massere af fordele ved at blive et Os Om Havet støttemedlem: udover at hjælpe os med fortsat at kunne afholde events mm. har vi sørget for en række rabataftaler med vores samarbejdspartnere, mulighed for at låne vores affaldsindsamlingsgear året rundt, og ikke mindst vil man modtage Os Om Havets nyhedsbrev, så man aldrig behøver gå glip af et fremtidigt arrangement. Hvis du har lyst til at støtte vores arbejde, skal du sende os en e-mail på medlem@osomhavet.dk med navn, e-mail og telefonnummer - så kontakter vi dig.

We create building materials for modern sustainable and toxic-free buildings combining hundreds of years of knowledge and tradition with modern production- and building techniques. Our aim is to make sustainable building commercially viable. Our first product is Lundby Pladen - a strong and fireproof building board made of unburned clay and woodfiber, designet for classic dry-wall construction. In the sustainable building industry there has been a long anticipation for this product. Unburned clay is the optimal material for inner walls in vapor diffusionon open building techniques as preferred in biobased sustainable building. With a strong and light building board we have solved the problem of unburned clay solutions being either too slow, heavy, fragile or expensive for commercial building. The building industry is responsible for between 17-40% of the worlds Co2 emissions. With Lundby Pladen it will be possible to fireprove biobased buildings with a low-emmission, toxic-free and environmentally harmless high quality material, and thus help making our buildings a genuine Co2-storrage instead of as now, a major Co2 polluter. In the coming years the building industry is facing new environmental laws, and will be increasingly depending on products like Lundby Pladen. We experience a major pull from the marked. Building supply markets, architects, craftsmen, standart house developers and entrepreneurs are waiting impatiently for our product to hit the marked.

The CargoGator is a bike trailer developed for moving cargo and parcels in the city. It is made from light-weight materials, can be mounted to almost any bike or e-bike, and with separate break-system, it is easy to handle for even non-experienced riders. With an ever growing number of last-mile and on-demand services in the cities, more and more pressure on the road networks, and a need to reduce our carbon-emission, we need to think of t.ex. bike deliveries as a part of the solution to solve transportion demands in the cities. Instead of everyone developing their own cargobikes, which can be expensive and only serves one purpose, as cargobikes, we will offer the CargoGator to bike-sharing programmes across Europe. For free. We have developed the CargoGator so it can be adapted to almost any e-bike, and the cover of the trailer, is made of strong PVC material that can be printed with any ads or commercials, which we will be selling to third parties, who wish to have their messages exposed in a new eco-friendly way on a whole new outdoor platform. Exposure of the ads will both be visible when riders are moving through the city, but as most pick-up stations of bike-sharing programmes are where people need them, the ads will also be exposed even when not rented out. Users of a shared bike/trailer solution will be both private persons living and moving in the city, and who occasionally will have a need of getting personal effects, large buys or other transported, but also professional riders, who are working for the growing number of on-demand services, couriers, supermarked delivery services a number of times a week. Instead of the riders themselves or their employers need to invest and allocate expensive cargobikes or other equipment, it will simply be possible to pick up a bike and trailer in the nearest bike-station, which is already financed through commercials. This is our core business model. There is ofcourse a market also for sellling the CargoGator to companies with their own fleet of bike-trailers or cargobikes, public institutions or other potential clients, who have a need or wish for a flexible and eco-friendly transport solution.

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!;)
