Ã
sions is based on emission factors from literature. The estimation is based on
the measurements performed in countries that are comparable with Denmark.
By comparable is meant countries that use similar incineration processes,
similar cremation techniques including support fuel and have a similar
composition of sources to lifetime exposure, lifetimes and coffins.

Danish measurements of dioxin emissions from three furnaces in two different
crematoria in 2001 showed concentration ranges of 0.2 – 0.7 ng I-TEQ per
m³ (n.t.10 % O2) and emission factor in the range of 180 - 930 ng I-TEQ per
cremation. The calculated average emission factor is 350 ng I-TEQ per cremation,
and the average concentration is 0.3 ng I-TEQ per m³ (n.t.10 %O2).
The measurements are assumed representative for all Danish crematory furnaces
(Schleicher & Gram, 2008).
A Danish substance flow analysis from 2003 estimated the dioxin emission
factor from crematoria to be in the range of 6-70 mg I-TEQ per year (90 %
confidence level), with an average value of 950 ng I-TEQ per cremation
(Henriksen et al., 2006). The estimate from Henriksen et al. (2006) is the
based on the latest dated measurements and is the one chosen for this inventory.
It has not been possible to find data for ammonia. Ammonia might appear in
lesser amounts, but will most likely be converted to NOX at the high incineration
temperatures.
