present data refer to slaughtering of cattle in three Danish cattle slaughterhouses
in 2001/2002. The main processes are following: 1) the cattle is delivered
to slaughterhouse in special trucks, 2) the cattle are stalled for a while,
3) the cattle are stunned and stabbed in the throat and the blood is tapped,
4) the cattle die from blood loss and head, skin, legs and intestines
etc. are removed from the dead bodies, 5)
the bodies are washed and cut into pieces and the meat is cooled 6) the
final product is packed and stored for distribution to the market. Non-edible
by-products such as bone and blood and intestine sold to bone
meal factories and skins are used for leather production. Wastewater
generated during the process is treated more or less (e.g. by screening)
before it is diverted to municipal wastewater treatment. Production processes
are automated and modern.
All data are derived
from Danish Crown's green accounts 2000/2001.
All inputs and outputs are determined by averaging data from Holstebro
Vest, Tønder and Aalborg
except emissions to water which are derived from
Tønder's green account. The
input mass of living cattle to the slaughterhouse has been estimated by
mass balance calculations.
All production processes as well as administration and local wastewater treatment processes are included. Maintenance of equipment, use of cleaning agents and chemicals are not included. Some cattle meat is frozen before distribution to the marked. The freezing process has not been included, but electricity consumption for freezing is about 115 kWh/t (Pontoppidan and Hansen, 2000). Packaging is not included.
About 30% of cattle slaughtered in Denmark are slaughtered in the three considered slaughterhouses.
Inputs and outputs associated with slaughtering in the three slaughterhouses are somewhat lower than observed earlier by Pontoppidan and Hansen (2000). The reason is probably that the cattle slaughterhouses have implemented cleaner production processes in the period between data collection for the two datasets.
