Aims 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).

  • oeoo in Rio de Janeiro

    Since summer of 2019, there is also a Brazilian subsidiary of oeoo in Rio. Laura’s team is carrying out cleanups of the surrounding beaches and bays, starting educational projects against plastic waste and working in cooperation with local fishermen to clean up Guanabara Bay and the Atlantic coast off Rio.

  • SeeHamster in Indonesia

    In cooperation with Schwarz Group (Lidl, Kaufland) and PT Wasteforchange Alam Indonesia (W4C), a local NGO, oeoo is launching a joint river purification project in the megacity of Bekasi on Java/Indonesia.

  • Cleaning up the Nile

    oeoo, together with the local initiative VeryNile and numerous volunteers, is launching a new long-term project in 2020 to clean the Nile and adjacent waters in Cairo and Luxor.


  • 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.

It took three years to collect and implement the donations, and in autumn 2016 the ship was launched in a shipyard in Lübeck. Since 2017, the SeeKuh has been in use worldwide, including six months in Hong Kong in 2018.

In 2018 oeoo opened an office and laboratory in Kiel/Germany. Meanwhile the association is represented with offices in Munich-Garching, Hamburg, Kiel, Hong Kong, Battambang/Cambodia and Rio/Brazil.

Long-term projects for the removal of plastic waste from water bodies are currently underway in Cambodia (since 2018), Brazil (since 2019), Indonesia and Egypt (since 2020). The SeeHamster waste collection vessels are used for these projects.

Another SeeKuh vessel will be completed and start its work in mid 2020.

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.

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 8 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.

Jessica Kullik


Bachelor of Arts (DH) BWL, since 2019 employee at oeoo

Why join oeoo?

Because I want to make the world a bit better with my work. I can do that with my full commitment at oeoo! Originally I only wanted to work in Cambodia for a few weeks. However, Günther asked me why I didn’t want to join the project organization in Germany with my knowledge in international sales and customer service. Since I had longed for a long time to get involved in charitable work, I didn’t hesitate for a second to work for oeoo.

Area of responsibility at oeoo

My tasks range from fund raising and project organization to social media marketing.

Through a targeted approach to companies, we want to inspire the industry for our work and win them over as partners for the financing of our projects, such as the waste recycling ship SeeElefant. Only with the support of the industry is it possible for us to realize the Marine Litter Cleanup for the purification of the waters worldwide.

Justine Kaczenski


From Hamburg, singer and social media manager

Why join oeoo?

Every day my work in the marketing industry cofronts me with mass consumption – and the effects are devastating! Where to put the garbage? Not in front of my front door … wrong! Everywhere lies plastic garbage and plastic bags lying everywhere on the beach. Our oceans are the purest dump! Together with oeoo I want to tackle this problem and raise awareness for marine waste and consumer behaviour!

Field of activity at oeoo?

In a digital world that is becoming more and more complex, I support oeoo in the content creation of social media channels. My tasks range from strategy development, editorial work to community management and influencer relations – almost everything that has to do with emojis at oeoo ?

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.

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.

Caroline Verna


Caroline, 37, French, lives in Rio since 2014 and is exploring the Guanabara Bay.

Why join oeoo?

I decided to join oeoo as scientific director because I fell in love with the city of Rio and its region. When I see Guanabara Bay in the city area, I see an amazing ecosystem, beautiful beaches, and it would be great if it were restored. In the northern zone, children still swim in it, although it is heavily polluted by sewage, garbage, gasoline and plastic waste (mostly household garbage). The local fishermen sometimes fish more plastic than fish. The mangrove forest, which used to cover most of the coastline, has been reduced. I believe that fish, dolphins and whales would return to a clean bay, of which there are now only isolated specimens. The health of children and their families in the North Zone could be improved, and economic and tourist opportunities in the region (fishing, beach activities, diving, sailing …) could be created. The bay is still alive and I hope that one day my children will be able to swim in it again safely.

Responsibilities at oeoo

Since we have relaunched oeoo in Rio, I am currently a bit of a girl for everything, although I am concentrating on the exploration of Guanabara Bay, mainly researching the types, amount and sources of plastic pollution, and building a network of contacts with universities and other NGOs active in Rio.

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.
