Australian Dairy Manufacturing Industry Sustainability Report 2007 ...

In line with international trends, there was a

general trend in Australia’s product mix towards

cheese and WMP production, and away from

butter and SMP lines. However, over the past

two years, strong commodity prices motivated

a significant re-balancing of company product

mixes back towards SMP and butter, to take

advantage of the higher relative export returns

available from these products (Figure 1).

Around 60% of manufactured product (in milk

equivalent terms) is exported. This contrasts with

drinking milk, where some 96% is consumed in

the domestic market.

10 Australian Dairy Manufacturing Industry Sustainability Report – 007/08

Dairy manufacturing is a complex business. Three

major production processes are used to produce

fresh dairy products, cheese and whey, and butter

and the range of milk powders (Figure – inside

back cover).

The energy intensity of these processes varies

considerably. All have fuel costs associated with

farm collection and the distribution of finished

products but product lines such as milk powder

require significantly more energy per tonne to

manufacture than other processed products.
