About Hiroki Kurahashi (Founder)

Kurahashi studied political science at Ryukoku University, in Kyoto. During this time he became interested in African politics, later earning a Master's degree in Southern African Area Studyies at the Post-Graduate School iof Ryukoku University.

After finishing graduate school, Kurahashi traveled to Europe where he learned about Blue Economy and Chido's Mushroom while in Hungary. He then went to Zimbabwe to join Chido's Mushroom project. learning about mushroom cultivation by volunteering in the project. 

When Kurahashi returned to Japan, he started cultivating shiitake mushrooms as well as researching methods to grow mushrooms on coffee waste in Japan.

【Blue Economy】

​Blue Economy was introduced by Professor Gunter Pauli, who had been an adviser at United Nations University, Tokyo, Japan.

In 'The Blue Economy', many business models learned from nature's efficiency in order not to make wastes are introduced.

It explains the importance of mobilizing resources around us and employment and profit which occur sustainably and in a chain, not traditional market economics based on core competence. 

​【Meeting Chido】

Kurahashi became interested in "Chido's Mushroom" which was introduced in Blue Economy.

The project in Germany cooperates with coffee shops in town, grows mushroom and sell it in the local market. It received influence from Chido Govera who mobilize resources in local communities and grow mushrooms on them in different communities in Zimbabwe.

Kurahashi left his work in 2014 and then went to Zimbabwe to join Chido's Mushroom project. learning about mushroom cultivation by volunteering in the project.

【Starting RE:ARTH】

After coming back from Zimbabwe Kurahashi started experimenting growing shiitake mushroom on coffee waste and failed many times.

However, some coffee roasters told him that there are many wastes other than coffee in coffee industry. Then Kurahashi started thinking how he can reuse those wastes and make something useful.

This is how Recycled Eco Totes have started.

RE:ARTH has been founded in 2017 on purpose of growing mushroom on coffee wastes and effective reusing of wastes from coffee industry.
