In 2011, the S²P AG developed a method in a combined production process

to convert straw into cellulose (pulp)and fertilizer.

 

Up to date, all other known production methods converting straw into cellulose

have not been able to solve the basic problem.

 

After obtaining the cellulose from the straw, all other production methods

do not offer an environmentally friendly solution on how to use or dispose

the basically toxic black liquor.

 

Along with a team of experts the S²P AG developed a method

to create an organic, long term, bio fertilizer out of the black liquor waste.

 

After the PF – Process has been tested and the results were confirmed

and secured.
