In the German city of Duisburg, engineer August Ernst has just made a successful experience in the field of mushrooms.

Mixed the used paper and tree leaves, it is inserted into a rotating tube 26 meters long and heated to 70 ° C. Moisture and constant movement make the mixture powder and in this powder grow much cleaner than in the charcoal soil.

This system of paper use has generated great hope in Germany. Its mushroom producers need 150,000 cubic meters of coal powder for their production. The economic cost of this amount is not joking and if everything was replaced by paper, in addition to the economy, the environment would also be winning.
