Variations in solid waste

production

Sites vary significantly in the quantities and types

of solid waste generated. Some sites produce

more than 50 times the solid waste per litre of

raw milk processed (Figure 15 and Figure 16),

which is reflected in the large variation between

maximum and minimum values recorded across

all manufacturing types and sizes.

Powder manufacturing sites produce (on average)

less than half the solid waste per litre of raw milk

processed (Figure 15). This could be due to fewer

types of products being manufactured, less need

for changeovers and cleaning, and more attention

to high volume efficiency.

Larger manufacturers are able to achieve, on

average, greater efficiencies of scale in terms

of solid waste produced per lire of raw milk

as evident in Figure 16. Manufacturing sites

processing more than 00 ML raw milk produce,

on average, less than half the waste per litre of raw

milk of smaller specialty manufacturers.
