THE PROBLEM Searching second-hand online requires navigating hundreds of platforms and incomplete listings, forcing shoppers to do the heavy lifting of finding and comparing relevant items. The decentralized and the fragmented second-hand market creates a time-consuming and frustrating experience for shoppers to locate desired items among incomplete listings and outdated platforms. THE SOLUTION Koral aggregates millions of second-hand listings into one searchable platform with categorized, indexed data to create a one-stop solution. This eliminates tedious searches across individual platforms, making shopping second-hand is easier by improving discoverability and streamlining the process of finding desired items online.

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.

minimass™ was founded in 2021 to solve one of the biggest environmental problems facing the world today –the carbon footprint of construction.

Klimakampen er en start-up, der laver klimakampagner for arbejdspladser, folkeskoler og gymnasier. I hold dyster ansatte og elever om at få klimavenlige vaner. Lidt en "Vi Cykler Til Arbejde", bare med klima. Konkurrencen varer typisk 4 uger og faciliteres i vores egen app. Her vælger man hvilke pointgivende aktiviteter man har udført og ser statistik for hvordan man klarer sig og hvor meget CO2 man har sparet. Vi afholdt flere kampagne med betalende kunder og forsøger nu at skalere. Vi sidder på kontor på KU Lighthouse - Tagensvej 16a Vi er tre i teamet. Nicolai der er klimaspecialist. Dan, der er programmør og Kristian, der er klimaformidler. Vi søger en til at hjælpe med kommunikation, salg og marketing.

While our eyes is on the fourth industrial revolution, we want to be part of the energy revolution and help to reduce the CO2 footprint in every single workplace. we move towards greener workplace by a software solution on energy optimization of dynamic mechanical systems (DMS). Our target industry for now is ventilation systems so called as HVAC for office building. The product is a software solution that monitors and optimizes energy consumption of HVACs. But why HVACs? Ventilations are installed in almost all office and industrial buildings. Only in Denmark, 12 M m2 of area is dedicated to offices and buildings. This corresponds to a huge energy consumption by HVACs (about 40% of total electrical energy consumption of a building and funny enough buildings are responsible for almost half of energy consumption of Denmark in a year). Despite of HVACs simplicity from system point of view, they are very complicated and confusing for the HVAC owners. The energy consumption and waste energy is not clear. Therefore, energy optimization becomes a long shot. 4i4’s product is solving these issues and brings values for the HVAC owners by peace of mind and valuable insight on how to optimize the energy and save on CO2 emission.

UNO econetwork is young startup developing a digital platform to help businesses make corporate sustainability due diligence easy. We are working on a SaaS solution that enables users to account for their own environmental, social and governance related risks, as well as keeping a track on their suppliers'. Through our platform, companies can minimise the need to answer and resend the same information over and over again. To save our planet, it is critical that all businesses act responsibly. However, many companies end up wasting valuable ressources and time on accounting, instead of focusing on what is really important. We wish to help companies reduce the amount of double-work in their sustainability journey, so they can focus on taking action.

Real estate and the urban environment have a profound impact on all of us We spend 90% of our lives inside buildings. And by 2050 almost 70% of us will live in cities. The built environment enables life, community and culture. But at the same time, it fosters loneliness and health issues. It counts for almost 40% of global CO2 emissions. It is the biggest living expense for most people. And nowhere is growing inequality more visible than in how we live. To overcome the challenges of population growth, climate change, growing inequality and social unrest, we need to move to a more conscious and responsible version of capitalism. A version that is market-based, but with equal priority for all stakeholders and with long-lasting impact. We are a European real estate company setting out to develop urban communities with inclusivity, liveability and sustainability at its core. We do not have all the answers yet, but we aspire to join forces with likeminded investors and partners – we are a team with the motivation, experience and ambition to be a pathfinder on this journey. We are Home.Earth

At Coastgrass we have developed a sustainable replacement to crude oil-based plastic materials. By collecting and upcycling eelgrass from the Danish beaches we can offer a variety of different polymer compounds with a much lower carbon footprint than traditional plastic materials. We believe in using renewable natural resources to create climate-friendly solutions, so that we ensure a sustainable future.

En vision om grøn mobilitet Bycyklen er den nye generation af transport for den urbane rejsende. Det er verdens første intelligente, elektriske delecykelsystem, som giver brugerne både fleksibilitet, mobilitet og brugervenlighed.   Bycykelsystemet understøtter hovedstadsområdets veludviklede infrastruktur og giver brugerne mulighed for at rejse på tværs af bus, tog og metronetværket. Det kan dermed betegnes som det fjerde ben i hovedstadens offentlige transportsystem.
