The precondition for the use of Biogas in Fuel Cells is the avoidance, or elimination respective reduction of detrimental trace gases, which are potentially harmful for Fuel Cells.

Hydrolysis rate of solid waste as a parameter for process control of digesters
© European Compost Network ECN e.V. (5/2003)
During anaerobic conversion of solid waste an accumulation of intermediate products due to varying substrate characteristics and input loads can lead to process failure.

Odour emissions and growth effects of composts at different stages of humification. long- and short-term kinetics of drum and windrow composting
© European Compost Network ECN e.V. (5/2003)
Source-separated kitchen biowaste was composted in drums in four sets of experiments during a time span of seven years, starting in 1995. Batches from the drum were stored in windrows and the curing of the windrows was monitored.

Correlations between enzymatic activities and physiochemical / chemical characteristics of MSW composts during controlled storage
