#FROMPRACTICE
realize ideas together
At Keepin, partnerships create true innovations. Together, we implement creative visions individually, as unique as your business.
Bumerang
Since March 2023, we have been working with Bumerang, an innovative reusable startup from Barcelona. Bumerang offers a digital, deposit-free reusable system that is characterized by flexibility and sustainability.
With over 250 partner businesses and more than 25,000 active users, Bumerang is a leader in the reusable sector in Spain. The company focuses on individually designed reusable products – including our KeepIn bowls and cups, which are used in various sectors such as restaurants, events, universities, and hospitals.
Bumerang's technology enables easy integration into existing processes and offers solutions such as "Bumerang Tap" for quick use without an app. The "Bumerang Return" system automates and efficients the return of containers.
Together, we are committed to a functioning circular economy and making everyday life more sustainable.
Jokey Holding GmbH & Co. KG
Jokey is not only our parent company, but also an active and committed user of KeepIn products. A true role model for reusable products in-house.
KeepIn produces individually branded reusable products in the Jokey design for internal events, trade fairs, or celebrations. Whether in production, administration, or field service - the products are in daily use and an integral part of the corporate culture.
We are particularly pleased that our employees themselves also rely on KeepIn: Through their own staff purchase, our reusable products can now also be used privately - a clear sign of lived sustainability.
We share with Jokey not only a close corporate structure but also a shared vision of a future-proof, resource-saving packaging world.
New Loop
Since December 2021, we have been collaborating with New Loop from Copenhagen – one of Scandinavia's most innovative reusable pioneers. New Loop is developing a digital, deposit-based return system for reuseable takeaway packaging, intended for use at events, within organizations and in urban spaces. Their system relies on custom-designed reusable cups, trays and bowls, each marked with a unique QR code for tracking and return.
New Loop supplies a variety of partners, including cafés, companies and large events and other collaborative initiatives. Their digital return system allows users to return used cups at designated return machines and get their deposit back within a few minutes.
Our partnership with New Loop demonstrates how well-thought-out reusable solutions and technological innovations can go hand in hand to bring about sustainable changes in consumer behavior.
Relevo
Relevo, an innovative reusable start-up from Munich, has been part of our partner network since September 2023.
Relevo offers a smart solution for catering, communal catering of all kinds, events, and restaurants to avoid single-use packaging. Customers can take food and drinks with them in high-quality reusable containers and return them within 14 days to one of over 3,500 partner locations in over 800 cities – completely deposit-free and with minimal effort.
Of particular note is Relevo's integration into educational institutions such as the Bonn Student Union, which has replaced single-use packaging in its cafeterias with the Relevo reusable system since the winter semester of 2022/23.
Our cooperation with Relevo demonstrates how reusable systems and technological advances can combine to enable sustainable changes in consumer behavior.
VfL Gummersbach
Since the 2023/24 season, KeepIn has been the official team-partner of VfL Gummersbach – entering the second season of a strong partnership with one of Germany's most traditional handball clubs.
Our high-quality reusable drinking cups are used in the VIP area of the SCHWALBE arena. Specially set up on-site return points ensure convenient and clean returns.
We share a common goal with VfL not only through the region but also through our shared goal of making events more sustainable and significantly reducing single-use waste. A strong local partner – on and off the field.

Down2Earth Materials is our distribution partner in Ireland and successfully brings our KeepIn reusable cups to the Irish market. The Cork-based company is a leading provider of sustainable packaging solutions and supplies the catering, retail, and event sectors with certified compostable, recyclable, and reusable food and beverage packaging.
