Emissions from biogas production are divided and reported in different sections
of this inventory according to use.
For the biogas production from organic waste with the purpose of energy
production, the fuel consumption rate of the biogas production plants refers
to the Danish energy statistics. The applied emission factors are the same as
for biogas boilers. See this IIR Chapter 3, Energy.
Biogas production from manure is included in Chapter 6, Agriculture.
The fugitive emissions of NMVOC and NH3 from the production of biogas
from sludge from waste water treatment should be investigated and possibly
added to the IIR Chapter 7.2.
Biogas production in this section only covers fugitive emissions from the
handling of biological waste, sludge and manure. This includes activities
like storage, pre- and after-treatment and fugitive emissions from the anaerobic
digestion that is the actual production. However, emissions on these
activities are considered negligible.

Emissions from accidental fires are categorised under 6D Other Waste. Emissions
that escape from building fires include SO2, NOx, NMVOC, CO, heavy
metals (As, Cd, Cr, Cu, Hg, Pb), particulate matter, dioxins/furans and
PAHs.

Emissions from building fires are calculated by multiplying the number of
building fires with selected emission factors. Six types of buildings are separated
with different emission factors: detached houses, undetached houses,
apartment buildings, industrial buildings, additional buildings and containers.

In January 2005 it became mandatory for the local authorities to register
every rescue assignment in the RQOLQH GDWD UHJLVWUDWLRQ DQG UHSRUWLQJ V\VWHP
called ODIN, ODIN is developed and run by the Danish Emergency Management
Agency (DEMA, 2007).
Activity data for accidental building fires is given by The Danish Emergency
Management Agency (DEMA). Fires are classified in four categories: full,
large, medium and small. The emission factors comply for full scale fires and
the activity data are therefore recalculated as a full scale equivalent where it
