In addition, this option is subject to land availability in
the vicinity of the distillery, also it is essential that the
disposal site be located in a low–medium rainfall area.
More recent investigations have indicated that land
disposal of distillery effluent can lead to groundwater
contamination. Deep well disposal is another option but
limited underground storage and specific geological
location limits this alternative. Other disposal methods
like evaporation of spentwash to produce animal feed
and incineration of spent wash for potash recovery
have also been practiced.
