Technology for wood fiber production for all kinds of wood

Technology for wood fiber production for all kinds of wood

The Bioextruder is a patented machine with a proven track record of over twenty-five years that is able to turn every kind of woody material into wood fiber. 

The extrusion process exerts pressure and friction on the material resulting in a temperature increase up to 125 degree causing the steam explosion and the defibration of wood: this changes the physical structure of wood and eliminates bacteria.
The machine is robust, reliable and can process all kinds of woody feedstocks.

The wood fiber machine is easy and ready to use, has superb water and nutrient holding capacity, low salt content, neutral pH, mixes easily in growing media blends and does not need further treatments.
