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.

  • SeeHamster in Cambodia

    In spring 2018, a cleaning and environmental education project started in Cambodia, which OEOO is carrying out in cooperation with the Thüringisch-Kambodschanischen-Gesellschaft e.V. and COMPED (Cambodian Education and Waste Management Organization).

  • Worldwide Cleanups

    OEOO organizes regular cleanups at various locations worldwide, in which OEOO members participate as well as numerous volunteers.

  • Recycling ship SeeElefant

    For 10 months, a team of ship designers, plant technicians, environmental technicians and project developers in Kiel worked on the planning implementation of the first SeeElefant. In spring 2019, the comprehensive research and concept study for the elimination of coastal marine pollution caused by plastic waste was completed.

  • ,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.

  • 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.


  • 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.


One Earth – One Ocean e.V. is awarded the Special Prize of the Gruner & Jahr SPA AWARDS 2019.

Günther Bonin receives the Special Prize of the Gruner & Jahr Spa Award 2019 from Brigitte Huber, editor-in-chief of BRIGITTE magazine, for her work against plastic waste in the oceans worldwide at a festive gala in Baden-Baden. In recent years, the Special Prize has been awarded to personalities such as 83-year-old oceanographer and environmentalist Dr. Sylvia Earle for her work in preserving the oceans, Franziska van Almsick for her social commitment and Prof. Dr. Michael Braungart for his commitment to eco-effectiveness (design concept cradle to cradle).

Nomination of the waste recycling ship SeeElefant for the federal prize ecodesign, the highest national award for ecological design in Germany. From more than 300 submissions, the jury nominated 31 projects, including the SeeElefant.

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.

More information and contact

Dr. Harald Frank


Economist, 56 years old, strategic partner of One Earth – One Ocean e.V.

Why do I work for OEOO?
Climate change, the loss of biodiversity and the littering of the oceans require new ways of thinking and solutions in economy and politics. Without dogmatism, but with a lot of expertise and pragmatism, Günther Bonin and his team implement ideas and projects in the field of water protection. In 2009, David Suzuka, Canadian biologist and winner of the Alternative Nobel Prize, called for “Give back the eco to the economy”. Economy and ecology are a perfect match in many areas. We can demonstrate this in particular with the OEOO large-scale project “Marine Litter Cleanup” and the SeeElefant pilot system.

Area of responsibility and consulting fields for OEOO

Project development & project management, strategy, business analyses, financing and subsidies. I am team leader of the implementation concept of the “Marine Litter Cleanup” and the SeeElefant pilot system.

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.

Jörn Anhalt


Specialist for Fund Raising and Corporate Partnerships, Member since 2019

Why join OEOO?

For over 20 years I worked successfully in various positions in industry and the media sector. However, more and more I was missing a meaningful task at work. Something I get up for out of enthusiasm even before the alarm rings. When I saw the reportage Plan B about OEOO on ZDF, I was on fire. I contacted Günther Bonin and OEOO. Already at the first personal meeting I had the feeling that it fits very well in terms of content and people. That’s why I now bring my network and my experience to OEOO in order to realize the big goals of the Marine Litter Cleanup.

Area of responsibility at OEOO

I support OEOO in the areas of fund raising and corporate partnerships. I am convinced that many companies, individuals, but also foundations and politics should contribute to our vision. We do this convincing work with the whole team on a daily basis.

Dr. Claudia Klein


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.

Laura Kita Kejuo


Laura (39), translator, has headed our branch One Earth – One Ocean Brasil since summer 2019.

Why join OEOO?

I got to know OEOO through an interpreting assignment in Rio. Günther wanted to find out if and how an offshoot of OEOO could be founded for cleaning projects in Brazil. In Rio, many tons of plastic waste end up in the sea every day (especially in Guanabara Bay, on beaches and rivers). Even though you can’t handle everything in one day, I was firmly convinced that long-term cleaning and education work was urgently needed in Brazil. In the meantime we have founded OEOO in Rio and carried out several cleanups. A lot can already be achieved with small steps.

Area of responsibility at OEOO

I coordinate our OEOO office in Rio. Together with my team we plan cleanups together with experienced fishermen, organize environmental protection lectures for children and adults, and establish cooperations for research and cooperation with local companies and experts.

Bopha Sean


Bopha (27) has been a staff member and project coordinator of OEOO in Battambang/Cambodia since 2018.

Why join OEOO?

I was entrusted by COMPED, the partner NGO of OEOO in Battambang, with the management of the OEOO environmental project. The project offers a great opportunity to protect the environment and biodiversity of our country by cleaning a section of the Sangkae River in Battambang. By recycling the plastic waste, we are obtaining a resource that would otherwise only be disposed in landfills.

Area of responsibility at OEOO

My job at OEOO is project coordination in the province of Battambang. I organise the project work plan for our volunteers, manage the budget and expenditures, coordinate with local authorities and relevant stakeholders, collect data and document the work. Finally, I join the SeeHamster collection team to clean the river and its banks.

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.
