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.

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!

Plastic Change en dansk miljøorganisation med et ambitiøst internationalt sigte Vi arbejder hårdt med at knække den stigende kurve over plastikspild. Plastik er overalt – på land og til vands. Tre generationers forbrug af plastik har sat sine spor. Kun en lille del bliver genbrugt eller destrueret. Resten ligger i naturen i hundredvis af år. Vi arbejder for at reducere vores enorme plastikproduktion ved blandt andet at eliminere unødvendig engangsplastik fra vores produkter, ved at sætte bedre rammer for hvordan vi designer produkter til mere genbrug, og det plastik vi ikke kan genbruge, skal vi kunne genanvende. Vi arbejder både på politisk niveau, sammen med befolkningen, i samarbejde med innovationspartnere, på internationalt niveau, sammen med forskere og med at uddanne vores fremtidige generationer om problemet. Plastic Change består af et fast dedikeret team og en række uundværlige frivillige kræfter. Alle yder en stor, uvurderlig og professionel indsats for, at organisationen kan gennemføre sine ambitioner om at knække kurven for plastikproduktion og hermed plastikforurening.
