PARAMETER CONTROL        
   
 
 
         
         
1. It is technically feasible to digest up to 15-20 % of grass in a wet digester    
2. Using grass will increase the dry matter content in your digester, if you     
digest very liquid products: grass can be used as carrier  material      
3. If the nitrogen concentration in your digester is too high because of  the    
manure or other waste streams: grass can reduce this problem
