FAQs

You've got questions, we've got answers.

How does the Kadeya low-waste vending system work?

By rethinking the bottled water supply chain entirely, we’ve created a circular system that makes a positive impact for both you and the planet with every sip, gulp and swig. Our full system is the world’s first closed-loop beverage system. Imagine the milk man of yore, but all done within a single machine. We tap into the water lines, run through an advanced filtration process. These are then served to you in glass or stainless steel containers that once returned are sanitized and reused. Our forever bottles are cleaned within the machine and sanitized using industrial grade methods.

What’s left is zero microplastics and less waste and carbon than single-use bottled water that’s even better than recycling—because our bottles keep getting used forever.

What happens in the bottle isn’t returned?

Nothing happens to the worker! We don’t want to hamper efforts to get water. We have a 1% loss rate factored into our fee. We will work closely with the job site to implement incentives to reduce loss rates. If loss rates are above 1%, the job site is responsible for purchasing additional bottles.

How do you know the bottles are clean?

We’ve developed a patent pending bottle cleaning system that we believe is the best in the world. We have worked with industry leaders like Ecolab to ensure industry leading cleaning.

What inputs do you need?

We tap into the local water line and need 220 V power. The system is ruggedized, but works best under cover. For environments that don't have plumbed water, we can also work with water tanks and delivered water.

How much does it cost?

We offer a pay as you go, "hydration as a service model". For most environments, we offer cost savings compared to single use plastic. Reach out to get a quote today.

a note from our
Founder & CEO

Hi! My name is Manuela Zoninsein, I’m the proud Founder and CEO of Kadeya.
Hi! My name is Manuela Zoninsein,
I’m the proud Founder and CEO of Kadeya.

Growing up in an immigrant family with resource-conscious values, I developed a penchant for questioning things. Launching agtech businesses in China and Brazil exposed me to the issue of single-use pollution. Working at Palantir in the US, I pondered creating a water bottle-sharing network like Citi Bike. MIT trials showed the demand for sustainable hydration without compromising convenience.

Meet the future of water. Meet the future of hydration.

My arrival in China in 2007 as a journalist marked a turning point in my life. Witnessing the shift from reusable to single-use water bottles among over a billion people in Beijing raised concerns about sustainability. While I was initially motivated by climate change and waste, I soon discovered a parallel pain: the logistical challenges related to single-use beverages.

The global trust crisis around water, particularly in the US, has led to a reliance on single-use options due to tap water unpredictability. Kadeya’s solution revolves around transparency, trust, and convenience. We address these real-world challenges with an affordable and accessible approach, transforming container sharing into a sustainable and connected endeavor. Through our "liquid railroad" system, we aim to revolutionize one bottle at a time, demonstrating how even simple actions like drinking water can ignite profound change.
