The anaerobic digestion of outdoor cultivated Rhizoclonium biomass was investigated in this study. The influence of applying mechanical and biological pre-treatment methods prior to the biomass digestion on the overall methane yields was examined. The results show that the application of a...

In cogeneration units cooperating with district heating systems the power rating of the turbine must not be chosen to cover the maximum demand for heat.
