Earliest ways of whey disposal included piping into rivers, lakes
or the ocean, funnelling into caves, spreading over fields and feeding
into ruminants. Another option would be to discharge the whey into
lagoons for oxidation or into the municipal sewage system, but the
high BOD and COD of whey usually leads to an overload of the system
(Kosikowski, 1979; Smithers, 2008). Disposing of whey by these
means provides no valuable product, and is costly and labour demanding
for the cheese manufacturer, who generally bears all the
direct costs of handling and transport. Therefore, in spite of the fact
that removal of whey from the premises releases pressure on the
cheese manufacturing plant (Kosikowski, 1979), these solutions are
not satisfactory. In order to develop integrated solutions for the cheese
whey problem, it must be considered as a resource and not only as a
waste effluent, in view of its large potential as a source of added value
products.
