...how Char2Cool happend and why.

The Water-Hyacinths-Carbonization-Project – The name under which we started our work in 2018. Today we are a registered non-profit NGO in Germany. Our aim was and is climate protection through water hyacinths utilization. Everyday we ask one question: “What is the next step?” to make our vision become reality… below you find our past steps and where they got us.


September 2017

Walter was invited by NABU International to join them on a trip to Ethiopia. After other water hyacinths utilization projects had little success, the idea was to turn the plants into biogas. 

Walter realized that this would be another “little success” project. Lack of demand and lack of infrastructure were the main problems. So another idea was needed…

All of 2018

2018 was the year of having ideas and re-considering them… until we got stuck with biochar. It can be produced off-grid, decentralized and is in demand.

So 2018 turned into the year of getting to know biochar… We tried out what ever we could think of: using solar cookers to carbonize, applying it in Walters garden or making briquettes from biochar.

May 2019

This was the month that Olivia joined to develop the production process and kiln that would finally be used in the field. After days and nights of prototype development and carbonization experiments, the C2C-Kiln was born. It is an affordable frugal engineering solution that is intuitive to use.

September 2019

The next step was to set up a trial production. With the support of NABU International, Olivia conducted a month-long feasibility study at Lake Tana, Ethiopia.

The trial was a huge success: The head of the village was amazed to see us use weed that caused so many problems. We got visitors from surrounding villages and even Bahir Dar, which is a four hour drive away. 


January 2020

What’s the best way to start a new year? Becoming an organization! Since the beginning of 2020 we are a registered non-profit organization in Germany.

At the same time, Olivia went back to Ethiopia to set-up a permenent production. This plan was was interrupted by Covid-19… but we were lucky, Peter Bassey from Nigeria heard of our work. He became the first independent producer of C2C-Biochar.


Our story doesn’t end here… everyday, step-by-step we are progressing. Check out our C2C-Blog to get the latest updates on our work. If you like what we are doing, support us. This way our story keeps going…

Your donation has a triple impact!

  • Farmers get access to biochar; Their crop yield and food security increases.
  • A biochar market is created; Producers like Peter can profit and create jobs.
  • More climate protection means less climate change; We bind CO2 and prevent methane.

Part of the problem or part of the solution?

I want to be part of the solution!
