Pork
Pork
is produced by
slaughtering
and cutting
the pigs
produced in agriculture.
The value of different classes
of pork vary
(see table
below) and
the environmental impacts associated with each class of pork
have been determined by price allocation
(see Weidema, 2003).

The main processes influenced by
pork meat demand
ex retail
store
are shown in the figure below
exemplified with prok neck ex retail store.
Figure
1: Market based product chain
diagram for pork meat (exemplified with ham) covering the most important
processes in terms of contribution to global warming. Boxes
refer to production processes. Names of grey boxes refer to the main
product of the processes ("Ham"
refer to the slaughtering process). Red arrows represent material
or energy transfer between two processes; green arrows represent saved
material or energy transfer as a result of displacements; green lines
represent displacements and red lines represent avoided displacements.
Further details can be found in the LCA
model. |
Slaughterhouse waste (bones, intestines etc.) is converted into bone-
and
blood meal
etc.
The products were previously used as ingredient in animal feed but are
presently incinerated due to fear of BSE
("mad cow disease").
The contributions
to global warming from these processes are too limited to be included
in the above diagram.
The
tables
below show potential
environmental impacts
associated with
pork demand ex slaughterhouse and ex retail. All data are provided per
kg
of pork.
