Denmark's National Inventory Report 2005 - Submitted under the ...

lated based on the lower heating values for waste listed in Table 3A-5 (DEA 2004b). It
has been assumed that the plastic content in weight per cent is constant, resulting in a
decreasing energy per cent since the lower heating value (LHV) is increasing. However,
the increasing LHV may be a result of increasing plastic content in the municipal
waste. Time-series for the CO 2 emission factor for plastic content in waste are included
in Table 3A-5.
Emission data from four waste incineration plants (Jørgensen & Johansen 2003) demonstrate
the fraction of the carbon content of the waste not oxidised to be approximately
0,3%. The unoxidised fraction of the carbon content is assumed to originate
from the biomass content, and all carbon originating from plastic are assumed to be
oxidised.

Straw
The emission factor for straw, 102 kg/GJ refers to Fenhann & Kilde 1994. The factor is
based on the interval stated in the EMEP/Corinair Guidebook (EMEP/Corinair, 2004)
and the actual value is the default value from the Collecter database. The same emission
factor is applied for 1990-2003.
Residual oil
The emission factor 78 kg/GJ refers to Fenhann & Kilde 1994. The factor is based on
the interval stated in the EMEP/Corinair Guidebook (EMEP/Corinair; 2004). The
factor is slightly higher than the IPCC default emission factor for residual fuel oil
(77,4 kg/GJ assuming full oxidation). The CO emission factors have been confirmed
2
by the two major power plant operators in 1996 (Christiansen 1996 and Andersen
1996). The same emission factor is applied for 1990-2003.
Gas oil
The emission factor 74 kg/GJ refers to Fenhann & Kilde 1994. The factor is based on
the interval stated in the EMEP/Corinair Guidebook (EMEP/Corinair, 2004). The
factor agrees with the IPCC default emission factor for gas oil (74,1 kg/GJ assuming
full oxidation). The CO emission factors have been confirmed by the two major
2
power plant operators in 1996 (Christiansen 1996 and Andersen 1996). The same
emission factor is applied for 1990-2003.
