dance with a covenant signed with the environmental
movement in 1986. After many years' research, we
have now found a processor who uses a new process
to isolate the cadmium-containing pigment, which
will be stored at the C2 Deponie waste-storage facility
at Botlek (Netherlands). Once the cadmium has been
removed, the plastic can be recycled.
Non-recycled industrial waste
Non-recycled waste increased in 2003, mainly due to
the commissioning of a new brewery in Ama
(Nigeria), which is not yet able to recycle brewers'
grains, and the smaller volume of brewers' grains
recycled on New Caledonia. Reporting accuracy has
also improved in recent years. Primary sludge (solid

Co-products
Brewing creates a number of co-products, the most
important of which are brewers' grains and surplus
yeast. Brewers' grains (wet malt residue) are valuable
as cattle feed. Surplus yeast is also used in animal
feeds and has applications in the pharmaceutical
industry and in the production of flavourings.
Brewers' grains are recycled entirely by the majori
ty of our breweries and partially in a small number of
cases. Surplus yeast is recycled entirely by over half
of our breweries and partially by the remainder.

AART VAN DEN BOOGAART
Where brewers'grains-the residue
of barley and other grains used in the
brewing process - can't be sold as
cattle feed, one option is to burn the
material in a boiler and return the
heat to the production process.
A brewers' grains boiler is being built
at the Ama brewery in Nigeria which
will cut its fossil fuel consumption by
3,000 tonnes a year and its green
house gas emissions by 8,000 tonnes.
The investment will be recovered in
five years.
