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!;)

GLYON is developing a CO₂-powered textile-to-textile recycling technology to help brands, fiber producers, and recyclers solve the growing textile waste crisis with a breakthrough chemical recycling process that turns waste into virgin-quality raw materials for new fibers—without fossil fuels. We address the massive problem of textile waste, a global crisis where over 92 million tonnes of textile waste are discarded each year—most of it ending up in landfills or incinerated. This contributes to major pollution issues but also forces the textile industry to continue its dependence on virgin fossil-based materials. Our solution targets fiber producers, brands, and recyclers who need circular raw material solutions. Our CO₂-based chemical recycling process breaks down polyester textiles into building blocks and leaves other fibers like cotton intact. Both PET building blocks and cotton can be used to produce new, high-quality fibers without the need for virgin oil and reducing water consumption and CO₂ emissions.

Hydrovertic is a startup focused on revolutionizing the horticulture industry by providing low-cost vertical growing systems. These systems enable greenhouse growers to produce plants more efficiently and sustainably, without the use of chemicals. Traditional horticulture methods often require significant space and can lead to nutrient runoff, which negatively impacts the environment. Additionally, the use of chemicals in plant production poses health risks and environmental concerns. Hydrovertic addresses these issues by offering a vertical growing system that allows for multiple layers of plants, supplemented with LED lighting. This system not only maximizes space but also reduces the need for chemicals, making the production process more sustainable and environmentally friendly. By adopting Hydrovertic’s innovative approach, growers can increase their production efficiency, reduce costs, and minimize their environmental footprint. This contributes to a more sustainable future for the horticulture industry and helps protect our ecosystems.

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.

PurCity's patent pending solution (GapS), consists of novel industrial facade panels that are great substitutes for exterior facades/flat surfaces of any New/Existing buildings. Leveraging from chimney effect/natural ventilation, polluted air is naturally sucked into the panels and forced to pass through a harmless chemical process that traps CO2, particulate matter PM2.5/10 & inorganic gases. Then clean air will be delivered into the building through the Air conditioning (HVAC) system. GapS utilizes smart monitoring and control solutions, to optimize its performance. The collected polluted liquid is continuously recycled, generating valuable byproducts like Hydrogen, pure O2 and CO2 that are sellable in the market, benefiting sectors such as food, cement and agriculture.

Klimascore er den nye danske standardparameter for klimavenlige hoteller. Igennem de sidste 4 år har vi arbejdet sammen med ledende hoteller i Danmark, samt afholdt en årlig kåring, Climate Award, for at finde Danmarks mest klimavenlige hotel. Klimascore er baseret på hotellernes egne data og direkte udledning. I nær dialog med hotelledelsen og nøgleansatte hjælper vi herefter hotellerne med at blive mere klimavenlige samtidigt med at de driver deres forretning fremad, både ift. at opnå besparelser, men også i forhold til branding, medarbejdertilfredshed m.m.
