Pioneers in their field

Expertise. Pioneering spirit. And a good dose of passion. Ute and Johann Zimmermann have been dedicated to natural plastics since 2007. In line with the family motto “whether my idea is really this good, depends on who is listening to me”, Johann founded the company NaKu together with his wife Ute to develop from now on natural plastics that protect people and nature from the plastic flood. NaKu is the plastic-free alternative to conventional plastics!
All products are natural, renewable and compostable.

DI Johann Zimmermann

DI Mag. Johann Zimmermann

Technical director

Together with his wife Ute, Johann founded the company NaKu in 2007 with the aim of developing plastics that cause less harm to people and nature.

When he conducts research for NaKu, everything that isn’t nailed down is used for experiments and processed into natural plastic. That’ s why he is known as “The brain of the mission”. In addition, he knows how to motivate his team and keep them on track.

Laura - Grafik

Laura Mokesch BA

With her calm and relaxed manner, Laura is solid as a rock when things get crazy in the NaKu office. She joined the NaKu team in July 2019 and gives free rein to her creativity in the field of graphic design.

Laura’s passion for fashion and textiles regularly takes her to foreign countries and small shops far from main streets.

Mike - Marketing

Michael Zeger


Michael “Mike” has worked in various marketing positions in international corporations and also in SMEs in his professional life so far. Similar to Clemens, he now wants to bring his experience to a company with a very strong environmental background and awareness of sustainability.

In his private life Mike grows fig trees with enthusiasm, which he then gifts after successful breeding. He also tries to breed all kinds of plants that come across his way. Chilli, tomatoes, cucumbers, peppers, etc. from his garden are always brought to the office for cooking. Mike’s “artistic” talent is not neglected either. If there is time, he makes sculptures and objects out of concrete.

Clemens Egger MSc

Clemens Egger MSc

Public Relations, Content & Campaigning

Looking for a job that does something good for the environment, Clemens joined us in August 2020. As an expert in sustainability and environmental protection, he supports us in communications and marketing.

On company excursions, he enriches us as a zoologist with his knowledge of the local fauna and makes us marvel again and again how important species conservation is for the ecological balance – even with nuisances like wasps. Apart from his biological and sustainable interests, Clemens is also enthusiastic about board games and shows his competitive side.

Tinkerbell - Bürohündin


Office dog

Tinkerbell has studied at the pet obedience school and has been working for NaKu since 2012. Her main duty is to loosen up the working atmosphere; anyone who doesn’t play along or cuddle her has lost.

She also likes to perform endurance tests with the NaKu products, sometimes on command, but also sometimes secretly under the desk, unseen by the rest of the NaKu crew. Tinkerbell also works as a doorman and a post dog for the company.
