Clewat Ltd
Clewat is a fast growing cleantech company from Finland, focusing on solving the plastic waste, excess biomass, oil spills and other pollution problems of our oceans, seas, rivers and lakes. The work of our vessels is supported by our own experts, who have knowledge of marine litter, and other problems of the water systems.
There are currently over 150 million tons of plastic waste in the sea, and the amount is rising by 10 million tons every year.
WHY CLEWAT?
If we continue littering at the current pace there will be more plastic garbage in our seas by 2050 than fish.
At Clewat, we take care of the development of nature on a daily basis and our mission is to make our seas plastic-free with a marine cleaning device developed by our innovator Johannes Myllykoski. The device works in an environmentally friendly way, utilizing the flow of water. It is also very efficient and collects up to 200 cubic meters of rubbish per hour.
“After the oil disaster in the Gulf of Mexico in 2010, I realized that there are still not good enough solutions to tackle the environmental problems of the sea. I realized I wanted to influence: make a device that collects oil properly.
It started with years of development work, during which I was advised that, why wouldn’t you do, with the same effort, a device that would also collect plastic garbage. I realized that utilizing the sea’s flow, it is possible to find a solution that would effectively improve both serious problems.
As the father of five children, the size of the plastic waste problem has been shocking information. It got me thinking that something must be done. In the future I want that my children could also enjoy the pure nature.”
-Johannes Myllykoski
Our goals are high
The device did not come easy. Myllykoski has devoted thousands of hours to developing it. However, a small prototype has grown in less than ten years into a device that is already operational in the seas, lakes and rivers.
Myllykoski has also already got recognition for his work, he won the Baltic Sea project’s first prize with his invention in 2018.
Clewat is a Finnish, internationally operating company, focusing on environmental technology, whose journey is just beginning. The technology is supported by a team of experienced professionals. We are happy to help to solve the problems of water systems from beginning to the end.
Clewat is also a member of UN´s Global Partnership on Marine Litter (GPML). The aim of it is to collect together global actors, who work to prevent marine litter. The network also concentrates in the implementation of the Agenda 2030- action plan.
