On our last visit to Baden-Baden, we watched how Christmas trees can be turned into biochar. Step by step, we followed and documented the process.

At the green waste collection point, our Christmas tree first went through a chaff cutter. The resulting chaff was then cleaned through several sieves. After drying, it finally went to the PYREG plant. At the end of it all, we were holding x-mas biochar in our hands 😊
