The Reusable Promo Campaign at Cologne Central Station

What incentives do we need to make café guests embrace reusable solutions?
That's the question we explored with Haferkater, leading to an exciting discount campaign.

The Vision

Imagine a central station where trash bins aren’t overflowing with coffee cups. Instead, travelers stroll through the halls, naturally holding reusable cups in their hands.

This is the vision behind our collaboration with Haferkater. We pursued two clear goals:

1. Discover whether financial incentives can encourage people to switch from disposable to reusable cups.
2. Show that long-distance travelers can easily use reusable containers.

Sustainability made simple: Start your journey in Cologne with a Haferkater coffee in a stylish reusable cup. Hours later, arrive in Berlin and return it at Haferkater. No trash — no hassle.

The Implementation

With Haferkater as a strong partner, we brought this innovative reusable project to life.

Every disposable coffee cup sold at Haferkater was marked with a special coupon sticker. But this sticker was more than just a piece of paper — it was the key to a pretty sweet coffee deal.

• Guests could return, download the Vytal app, and get a free coffee in a reusable cup.
• But that's not all! As an extra thank-you, they received a 10% discount on every additional coffee in a reusable cup at Haferkater throughout September. That’s what we call real engagement!

Conclusion

Our reusable promo campaign at Cologne Central Station is a shining example of how innovative ideas and strong partnerships can drive positive change. By combining financial incentives with practical solutions, we make it easy for people to contribute to environmental protection. Together with Haferkater, we're proving that the future of coffee drinking is sustainable.

Let's make the world a little better — one coffee at a time. ☕🌱
