Spreadable (Smørbart
smør fx.
"Kærgården")
“Spreadable” is produced by mixing butter and
rapeseed
oil.
Butter is produced in excess in the market and
no significant processes are influenced by a marginal demand.
Rapeseed oil production is determined by the market demand and a demand
for “spreadable”
influences all processes in rapeseed oil production.
The main
processes influenced by
"spreadable"
demand are shown in the figure below.
Figure 1: Market
based product chain for "spredable" covering the most important
processes in terms of contribution to golbal warmng.Boxes refer to
production processes. Names of grey boxes refer to the main product
of the processes. 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.
