What is RE-ZIP RE-ZIP is a circular packaging concept offering circular packaging to more or less all players in the ecommerce industry. By circulating and hence reusing rather than using single-use packaging (even recycled) we save CO2 even the first time a packaging is reused. It works likes this RE-ZIP delivers the packaging to webshops who offer the sustainable packing solution to their customers at check-out for a minor fee (paid back via reward voucher upon returning the packaging). Upon receipt of the goods the customer folds the RE-ZIP packaging to a return format and return it at a Drop Point. The packaging is returned to the RE-ZIP warehouse for cleaning and re-circulation to the webshops. The RE-ZIP packaging can be circulated up to 10 times, but more importantly the packaging will begin saving CO2 Within the first or second use – depending on the type. RE-ZIP has developed a state-of-the-art backend system supporting the above process and are currently operating in Denmark, UK and Poland. Hence working at RE-ZIP will offer you in-person colleagues in Denmark and remote colleagues in before mentioned countries and more to come. Working at RE-ZIP Working from the Danish RE-ZIP HQ you will find a bunch of nice new co-workers who appreciate to work from the office most days, because the energy we create together is important for us. That does not mean that you have to be here all day every day. You will have flexible working hours to accommodate your daily life. The atmosphere in the office is laid back and rather than working solo on projects and tasks we gather and combine our skills. Send us your application to come join us in our mission to change e-commerce packaging for good.

Our planet is overheating, biodiversity is reducing rapidly, and natural resources are being depleted. With 40% of global energy-related CO2 emissions and 30% of global landfill waste, construction plays a significant role in our planetary crisis and is by far the most polluting sector. We need to do things differently. Stykka takes you on a journey toward a future where the construction industry is part of the solution rather than the problem. We’ve set out to develop scalable solutions that enable like-minded developers and investors to build more sustainable, efficient and profitable. With Stykka we enable forward-thinking developers to build sustainably and be part of the solution rather than the problem. We use cutting edge technology like 3D scanning, digital fabrication, and distributed manufacturing to create new experiences and amazing, sustainable products for an array of clients.   With Stykka we aim to leave a positive impact on our planet and solve one of the biggest problems of our time, and we want you to be part of this journey.

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.

ESEBA, a deep tech startup from DTU, transforms low-quality textile waste into MDF boards without binders or formaldehyde. We offer a sustainable, non-toxic alternative to traditional wood-based panels. Textile waste is a massive and growing problem in Europe – less than 1% is recycled into new products, and most ends up incinerated. At the same time, formaldehyde regulations are tightening, and deforestation pressures are increasing demand for alternatives to virgin wood. ESEBA’s mission is to enable local, circular board production through a scalable, plug-and-produce production line for furniture manufacturers.

Treesy ApS er en dansk climate tech-startup, der gør det nemt, billigt og gennemskueligt for privatpersoner og virksomheder at tage konkret klimahandling gennem træplantning i Tanzania. Mange mennesker og virksomheder ønsker at gøre noget for klimaet, men oplever i dag, at løsningerne er uoverskuelige, dyre, abstrakte eller svære at stole på. Samtidig vokser både klima- og biodiversitetskrisen, og behovet for skalerbare, troværdige og handlingsorienterede løsninger er større end nogensinde. Treesy er skabt for at fjerne barriererne for klimahandling. Vi tilbyder en enkel abonnementsbaseret model, hvor kunder planter træer som en konkret måde at reducere og balancere deres klimaaftryk. Vores tilgang er baseret på konservative beregninger, radikal transparens og lokal forankring. Alle træer plantes i samarbejde med lokale partnere i Tanzania og bliver: • individuelt geo-tagget • monitoreret mindst fire gange årligt • passet og genplantet i op til tre år efter plantning Vi planter et diversificeret mix af træer med fokus på både klima, biodiversitet og lokal økonomi. Det betyder, at vores indsats ikke kun handler om CO₂, men også om at styrke økosystemer, skabe lokal indkomst og opbygge mere robuste lokalsamfund gennem agroforestry og frugttræer. Treesy adskiller sig ved at kombinere: • lav pris pr. træ • høj grad af transparens • direkte lokal tilstedeværelse • individuel geo-tagging af træer • en bevidst fravalg af dyre certificeringssystemer til fordel for direkte dokumentation Vores ambition er at gøre klimahandling tilgængelig for alle — og samtidig sikre, at indsatsen skaber reel, målbar og langsigtet impact. Treesy er stiftet af iværksættere med mange års erfaring fra udviklingsarbejde i Afrika og et stærkt lokalt netværk. Vi tror på, at ægte forandring skabes, når klima, biodiversitet og social udvikling tænkes sammen i én samlet løsning. Vores mission er enkel: At gøre det så nemt og gennemskueligt som muligt at give mere tilbage til planeten, end man tager.
