Goals of the Association

The environmental organization One Earth – OneOcean e.V. (OEOO) deals with the protection of the environment, in particular the water and coastal protection.

It has set itself the goal of developing and implementing a concept, as water bodies worldwide can be freed from plastic waste, but also oil and pollutants.

In the multi-stage concept of the “marine litter cleanup”, plastic waste is collected by special refuse collection vessels and then recycled or converted back into oil. From a ton of plastic waste, approximately 900 liters of oil could be recovered.

In addition, the association is involved in the field of oil purification, microplastics, research, education and documentation on marine littering, both nationally and internationally, in order to achieve a change in the behavior of people with regard to (plastic) waste in the medium to long term.

In 2018 One Earth – One Ocean e.V has become an official partner of the UN Environment #CleanSeas campaign.UN Environment launched #CleanSeas in February 2017, with the aim of engaging governments, the general public, civil society and the private sector in the fight against marine plastic litter.

  • Marine Litter Cleanup

    In autumn 2016 the launch of SeeKuh, a special catamaran developed by OEOO for the collection of plastic waste, took place.

  • The SeeKuh on tour in Asia

    In january 2018, SeeKuh was on tour  in Hong Kong for half a year. Asia is the region most heavily polluted with plastic waste worldwide.


  • SeeHamster in Cambodia

    In the spring of 2018, a cleaning and environmental education project in Cambodia will be launched by OEOO in cooperation with the Thuringian-Cambodian Society e.V. and COMPED (Cambodian Education and Waste Management Organization).

  • Project development recycling ship SeeElefant

    Since the beginning of 2018, a team of ship designers, plant engineers, environmental technicians and project developers has been working in Kiel on the planning implementation of the first SeeElefant

  • ,Microplastic Pollution Map’ in cooperation with shipping companies

    In order to contribute to the research into the medium to long-term effects of microplastics on humans and animals, OEOO is engaged in setting up a global database on the levels of pollution in the world’s oceans.

  •  International Marine Litter Database

    The pollution of the water bodies by (plastic) garbage is nowadays also becoming increasingly important in science.

  • International Oil Purification Project in Nigeria 2017

    The Niger Delta in Nigeria is one of the most oil-rich areas in Africa, but the landscape is regularly polluted by oil spills on the production facilities and pipelines.

Founding / History

Günther Bonin, former Munich IT entrepreneur and enthusiastic sailor since his youth days, was annoyed by the ever-increasing amounts of plastic waste which he found on his sailing trips even in the most remote locations.

According to own research, plastic waste was only explored on a selective basis, and there were no technologies to recover plastic waste from the sea. He decided to let his IT company rest and deal intensively with solving this global problem.
In 2011, he founded the environmental organization One Earth – One Ocean eV, based in Munich and built up a team consisting of marine biologists and experts like Thomas Hahn, who co-ordinated the victory of the America Cup at BMW Oracle, or metal constructor Michael Lingenfelder, and other volunteers, to create concept of “marine litter cleanup” for the cleaning of world-wide water bodies from the plastic waste.

Meanwhile, the focus has expanded and OEOO is also working on bringing oil and chemicals out of the water.

First prototypes of the SEEHAMSTER, smaller ships for garbage collection, have been used since 2012 in inland waters and the Baltic Sea.

In June 2015 the SEEKUH was the first prototype of a large coastal seaport.

The collection of donations  and implementation lasted for three years. In  autumn 2016, launching was taking place in a shipyard in Lübeck. 2017 and 2018 the SEEKUH will now be used worldwide. In 2016 OEOO opened an office in Hamburg.



One Earth – One Ocean e.V. is honored with the prestigious GreenTec Award 2013 for its “marine litter cleanup” concept. The GreenTec Awards are Europe’s largest environmental and economic award, in which the most innovative green products, projects and environmental technologies are awarded annually in various categories.


Nomination of the SEEKUH for the Bundespreis ecodesign, the highest state award for ecological design in Germany. The jury nominated 26 projects, including the SEEKUH, from more than 350 submissions.

The award, which is presented annually by the Federal Ministry of the Environment, distinguishes innovative products, services and concepts that have an outstanding ecological quality, innovative approach and high design quality.


The Deurex oil-binding cotton PURE, with which OEOO has been helping to eliminate oil contamination in Nigeria since 2015, was awarded was awarded the European Inventor Award 2017 in Venice in June 2017.

The European Patent Office awards this award every year for outstanding inventions. OEOO has been mentioned as a reference in this context.



Nomination for the Ocean Tribute Award 2018 in the category Society. The award, presented by the Prince Albert II of Monaco Foundation in cooperation with the German Sea Foundation and the water sports fair boot Düsseldorf, honors the most innovative and sustainable ideas on the subject of marine conservation.

Our Team

In addition to Günther Bonin, the founder of OEOO, and a core team of close-knit employees in and around Munich and in Northern Germany, there are additional members who support the work of the association in an ideal, financial and/or active way.

Dr. Rüdiger Stöhr


Microbiologist and teacher for biotechnology / biology from Kiel, member since 2012

Why join OEOO

When Günther and I were ‘gossiping into the evening sky’ above the Kiel harbor, it was immediately clear that we were swinging on a wavelength. From the first small joint ideas, projects such as “Jugend forscht”, microplastic monitoring, oil wool PURE, plastic filters, etc. emerged, and there is a very exciting association work, for which I am enthusiastic.

Area of responsibility at OEOO

As an OEOO employee, I am responsible for the microplastic project. I hold lectures, workshops and give internships on the subject of plastic in the sea. I am interested in cooperations in which the plastic problem is researched and presented in a responsible manner.

Bettina Kelm


Environmental Education Officer, since 2013 honorary member of OneEarth-OneOcean e.V.

Why join OEOO

I am a freelance journalist for travel and nature and I live in Bichl/Bavaria. In the Gulf of Panama 2010, I was shocked by how turtles had to deal with plastic waste and spontaneously wrote a comprehensive article about plastic in the sea. In 2012, I met Günther and his concept of “marine litter cleanup”. From the Panama-reportage, a photo lecture about plastic waste was made.

Area of responsibility at OEOO

Since 2013, I have lectures on schools and environmental education events all over Germany (focus on Bavaria). Depending on the age of the audience, there are different lecture concepts, from primary school pupils to adults. From the pollution of the Pacific Ocean off Panama, the curve stretches over the global situation in the world’s oceans to the extent that our German waters are already heavily loaded.

Frank Brodmerkel


50, communication expert from Munich, working for OEOO since 2012.

Why join OEOO

When I read about OEOO 5 years ago in the daily newspaper, I spontaneously offered Günther the support of my PR agency. Plastic waste has received great attention as one of the most pressing civilization problems in recent years. But it does not help the environment to talk about it. We must act at last!

Area of responsibility at OEOO

At OEOO, I support the association’s concerns through press and public relations, including a regular newsletter for members and interested parties. I ‘m also responsible for the OEOO web presence. It is intended to further increase the awareness of the association and to help to win new members.

Dr. Claudia Klein

claudia (dot) small (at) OneEarthOneOcean (dot) com

Freelance journalist in Berlin, active with OEOO since 2018.

Why join OEOO

Because plastic does not belong in the sea and because I do not want to see how our beautiful earth suffocates in garbage. Although Berlin is not by the sea, something needs to be done.

Area of responsibility at OEOO

As spokeswoman, I support Günther Bonin in lectures, interviews, appointments and press inquiries. Together with Frank Brodmerkel I work on the public visibility of our association.

Birgit Westermayr


Member of the first hour at OEOO.

Why join OEOO?

Because plastic has lost nothing in the environment. Clean water, clean food and a functioning oxygen production are of central importance for all of us.

Area of responsibility at OEOO

I support the association and above all Günther Bonin with the administration, bookkeeping and member support.

Lennart Rölz


28, Schiffbauingenieur und Offshore-Anlagentechniker, seit 2015 für OEOO aktiv.

Why join OEOO

Lennart has often been confronted with the problem of marine plastic waste during his travels. When he then dived in Sri Lanka in a littered bay and had to see how carelessly people are handling plastic waste, it was clear to him: It must be acted!

He got to know One Earth – One Ocean and Günther and is very pleased to be able to contribute to improving the condition of our oceans.

Area of responsibility at OEOO

Shipbuilding is his profession, nature conservation is a matter of heart for him. The marine litter cleanup project of OEOO thus perfectly combines these two areas for him.

His task is the technical planning of the SEEELEFANT up to the implementation. Key points are the integration of a complete sorting and recycling plant as well as a lubrication system into the ship structure.


Erich Groever

61, graduated engineer (TU) food and environmental technology, owner of an engineering office for waste and environment, has been active since 2013 for OEOO.

Why join OEOO

In 2013 I had first contact with Günther in the tests of the first SEEHAMSTER. His enthusiasm immediately struck me, his vision of clean seas is convincing. The global pollution of the oceans is a basic cause, we can not even overlook the consequences. Therefore my cooperation, in order to actively counteract and find a solution.

Area of responsibility at OEOO

Environmentally sound waste management is my profession and my vocation. I add to Günther’s idea of collecting plastic waste from the sea my professional background and the aspect of further processing. My task at OEOO is to develop the most ecological, economical and economical solution for utilizing the waste of plastic material.

Holger Borchert


Independent entrepreneur in Hong Kong and member since 2016. He cares about the set-up and the activities of OEOO in Asia.

Why join OEOO

In spring of 2016, I met Günter Bonin and OEOO as part of an event at GATE in Munich. After a short time, I realized that I would be working here in Hong Kong for the OEOO goals.

Area of responsibility at OEOO

I set up the Asian office of OEOO in Hong Kong and take care of all the interests of the association here in Asia. In particular, I am here for the first active use of our SEEKUH and the planned SEEELEFANTEN in the near future.

Bernhard Herbst


60, from Wuppertal has been on board since 2016 and is responsible for sponsoring search

Why join OEOO

Bernhard knows Günther since 1975, their school days. Music and joint projects have never let the contact break. On the occasion of a class meeting the first contact with Seehamster & Co. came about. The OEOO concept convinced Bernhard so much that he decided to contribute all his strength and experience. His motto is a quote from Willi Brandt: You have to take life as it is, but you do not have to leave it!

Area of responsibility at OEOO

At OEOO, Bernhard helps to master the ever-increasing financial challenges facing the club. Sponsors, patrons and sponsors are sought, contacted, maintained and integrated for the benefit of the common goal. That is why the blonde “Viking” gets away from the new OEOO web platform that the vision of worldwide maritime garbage collection is taking shape.

Emmanuel Duru


36, from Nigeria, engineer for chemistry and environmental engineering, master of science at TU Munich, member since 2015

Why join OEOO

Emmanuel studied at the Technical University of Munich and has already gained international professional experience in connection with oil spills. He knows the situation in Nigeria and is glad to be able to do something with his know-how directly for the recultivation of his homeland.

Area of responsibility at OEOO

Emmanuel Duru is responsible for the clean-up of water bodies on site in Nigeria. Since 2015 he has been in Nigeria for OEOO several times to coordinate various cleaning projects with PURE oil binders and to win political bodies and NGOs.
