3. KEY FIGURES FROM EXISTING PLANTS
CONSTRUCTED FROM 1990 - 1997
The existing plants vary greatly in size and design. The largest plant,
measured in per day biomass treatment, Ribe, with 79 manure suppliers,
applied 444 of biomass per day in 1998, and the smallest plant shown in
Table 12.1, Hodsager, with only 6 manure suppliers, applied 51 of
biomass per day. Normally approx. 75 % of the biomass application is
manure, and approx. 25 % is organic waste. Table 12.1 shows some key
figures from 12 plants constructed from 1990 to 1997. Another two plants
were constructed in 1997 and 1998 but existing data from these plants do
not include a whole year of normal operation.
Considerable variation appears in biomass treatment capacity and
thus biogas production. It also appears that gas yield, defined as biogas
