The ethanol distillery has a capacity to produce 32 million litres over a 36 weeks production period. This is split between 30 400 000 litres of high grade, 96.5% absolute potable ethanol and 1 600 000 litres of low grade ethanol (feints). The plant also has an anhydrous plant capable of producing 10 000 litres per day of fuel grade, 99.9% absolute ethanol that can be blended with gasoline to produce blended bio-fuel for vehicles.
The current feedstock material for the distillery is molasses which is obtained from both RES factories and augmented by some molasses from external sources.
A by-product of the ethanol distillery is Concentrated Molasses Stillage (CMS) at 400 brix. This by-product is sold to a company called Enviro for blending and onward selling to farmers for use as fertilizer.
The Distillery was built and commissioned in December 1995 with an initial production capacity of 12.5 to 13.7 million liters a year. After an expansion program in 2006, the plant was sized to produce 32 million liters over 36 weeks.
After the expansion the ethanol quality improved from the BP99 specification to UDV3 grade. The expanded plant incorporates two distillation streams, two fermentation streams and one evaporator plant. The new plant employs yeast propagation and multi-pressure distillation technology and this has reduced production costs.
