What makes the PF – Process so unique?
During the production process, turning straw and or other bio-masses into cellulose (pulp),
the by-product ‘black liquor’ is created.
The black liquor is mainly composed of lignin and hemi-cellulose and forms a heavily toxic waste.
The PF – Process was designed to use the hazardous by-product
to make a high quality, organic and long term bio fertilizer.
The PF – Process is the only process worldwide that offers this environmentally friendly solution.
In the 1st phase, the straw is cooked in a water/chemical solution.
During this phase, the straw structure is broken up into its main components:
cellulose (pulp), hemi-cellulose and lignin.
In the 2nd phase, the cellulose (pulp) is washed out of the solution
and subsequently dried and pressed.
The cellulose is unbleached and ready for sale to the paper industry.
In the 3rd phase, the water and chemicals are recycled
out of the remaining solution for re-use in the cooking process.
After recycling the fluids we are left with the by-product, the so called black liquor.
This tar like substance has a fairly high viscosity.
In the 4th phase, the black liquor is turned into a high quality, organic and long term bio fertilizer.
For easy packaging and handling, the fertilizer is granulated.
The entire production is a closed-circuit process.
The PF – Process creates no waste-water.
The PF – Process requires less energy compared
to other standard cellulose (pulp) production processes.
The entire production line including process and assembly equipment is basically
state of the art.
