The anaerobic digestion of biowaste provides an alternative to composting these residual waste flows. An examination is to be made of optimising the digestion of biowaste (residual waste and organic waste) by the predetermined metering of trace elements in the two-stage GICON process. The biowaste in question was obtained from the separate collection of waste. An investigation was to be made to determine at what point in the process the trace elements must be added and in what form in order to optimise the gas yield and, more importantly, to optimise the decomposition of the organic substance, thereby shortening retention time in the decomposing organic substance (and thus restricting the production of carbon dioxide). A problem common to all decomposing organic substances is that carbon dioxide emissions are produced but no usable energy whatsoever is produced from the waste matter. If as much of the organic substance as possible is broken down to methane and hydrogen, the subsequent energy recovery does, it is true, produce the same amount of carbon dioxide but by way of a yield of energy that is viable for generating energy.
A demonstration under scientific and metrological supervision was to be given of the measures selected for reducing climate emissions in practice with the main emphasis on reducing the accumulation of digestate and developing new substrates. In addition, qualitative and quantitative proof was to be provided of the effectiveness of the measures as well as an economic evaluation of the costs of preventing carbon dioxide associated with the application of the measures in practice.
The two-stage GICON process was to be examined at the DBFZ on a laboratory scale and the trace element requirements determined, using different analytical methods. A selection of suitable FerroSorp® was made at P.U.S. Produktions- und Umweltservice GmbH and delivered.
