Circular Explorer

The Circular Explorer is on a journey to preserve our oceans and raise awareness about the circular economy.

Discover the Circular Explorer

The Circular Explorer is a pioneering solar-powered catamaran created to recover and recycle plastic from the world’s oceans and rivers. Built in partnership with One Earth – One Ocean, the Circular Explorer is also a vessel for education and science.

Watch the recap of our Manila Bay launch event.

Rising marine pollution

Our oceans play a vital role in maintaining the balance of our ecosystems – from the food we eat to the air we breathe. This balance is being threatened by pollution, and the statistics are alarming:

  • Scientists estimate that our oceans currently contain over 150 million metric tons of plastic waste
  • Each year, an estimated 8 million more metric tons of plastics end up in our oceans
  • There are more than 5 trillion pieces of plastic floating in our oceans
  • We currently recycle only 9% of the 381 million metric tons of waste we produce
  • At the going rate, the plastic in our oceans will outweigh fish by 2050

The circular economy solution

 

To tackle marine pollution and clean up our oceans, we need to shift to a circular economy based on the principles of reduce, reuse, recycle. That’s why we launched the Circular Explorer. The Circular Explorer can recover up to four tons of marine litter every day. To maximize our impact, the Circular Explorer is also an education center and scientific laboratory. We empower next-generation changemakers to take action, and collect and share data on microplastic pollution to push the boundaries of marine science.

The Circular Explorer’s mission

The Circular Explorer represents our commitment to protecting the oceans and accelerating the circular economy to preserve our ecosystems.

The Circular Explorer is based on three pillars:

Recycling

Putting the circular economy in motion

The Circular Explorer cleans up rivers and coastal areas to prevent plastic from ending up in landfill or entering the ocean. We recover up to four tons of floating plastic each day. Together with local recycling partners, we transform the recovered waste into new resources. Our Geocycle waste management business turns non-recyclable waste into an alternative energy source.

Education

Educating for change

The Circular Explorer is an education center empowering local communities to take action to save our oceans. Together with One Earth – One Ocean and local partner institutions and communities, we raise awareness and educate people about the importance of marine preservation and the circular economy. We develop and share customized learning toolkits and education workshops to communicate best practices for taking action locally. Our on-board sessions and clean-up events are an opportunity for the public to get involved and be part of the solution.

Science

Advancing marine science

The Circular Explorer is a floating scientific laboratory and mobile research center. On our journey, we collect data to help us learn more and create better solutions for the future. We partner with leading scientific institutes, researchers and students to contribute to marine research projects. Using the specialized sensors we have installed on the vessel, we collect data and map water quality and microplastic pollution. We then use and share this data to explore scientific solutions and encourage better recycling and waste management practices.

Solar panels

The solar panels on the Circular Explorer can be tilted up to 33 degrees and turned 360 degrees to follow the sun. The power is stored in batteries on board the boat that drives the electric motor.

  • Area of 60 square meters
  • 360 degree rotatable to follow the sunlight
  • Solar panels adjustable up to 33 degree
Conveyor belt

The conveyor belt is lowered into the water when cleaning starts.

Plastic waste is then transported up to the boat for manual sorting. Single sort split plastic is recycled for reuse in cooperation with local partners and converted into new products.

The remaining plastic that is unable to be recycled will be used as an alternative energy source.
