Anaerobic digestion

The anaerobic process is positioned exactly between the so-called “wet” and “dry” digestion processes. It is used with dry substance contents of 12-18%, which allows exploiting the benefits of both procedures.


  • maximum purity in the digestion process
  • insensitivity to variances in feedstock composition
  • thermophilic operating temperatures
  • very simple digester design avoiding the risk of clogging or foaming
  • the process may be adapted to different dry substance contents during operation
  • many feed stocks can be digested without producing waste effluents
  • simple and effective control
  • high gas yield
  • economical even at small throughputs
