The Promeco Bioextruder is a patented machine with a proven track record of over 25 years. The extrusion process exerts pressure and friction on the feedstock resulting in a temperature increase causing the steam explosion and the defibration of the wood: this changes the physical structure of the wood and the heat eliminaters the bacteria.

The robustness and reliability of the machine allow the treatment of all kinds of woody feedstock. 

The wood fiber from the Bioextruder is easy to use and doesn't need additional treatments. It has superb water and nutrient holding capacity, low salt content, neutral pH and mixes easily in growing media blends.
