Effluent from sugarcane molasses-based distilleries (spent wash) pose serious environmental threat for contamination of groundwater & waterbodies. This is the single biggest impediment for ethanol capacity expansion in Indian context. This ZLD compliant spent wash management technology allows distilleries to produce various value-added marketable products (viz., FCO grade potash fertilizer, cattle feed binder etc.) from spent wash.
- Process involves recovery of FCO grade potash fertilizer, organics (binder in cattle feed formulation), activated carbon & water, using spent wash as resource.
- Indigenous potash fertilizer – import substitution
- De-linked from sugar mill - more alcohol from same distillery
- ZLD + Sustainable environment
- Ethanol capacity expansion – enabling scope to achieve fuel blending target
Commercial plant is operational.
Potential client base:
India: >350 distilleries
SE Asia, Africa, Brazil etc.
The process is ZLD compliant and all solid streams are saleable product – environmentally safe & benign process; Implementation of the process would lead to better environment in particular for land/water bodies around the distilleries.
The technology has been licensed to M/s Aurangabad Distillery Limited (ADL)
The unit – attached to ADL’s 60-klpd distillery at Walchandnagar, Maharashtra – is operational.
Distillery spent wash, lime, magnesia, nitric acid, sulphuric acid etc.
Generic equipment required in chemical plant, viz., reactors, settlers, filter press, dryers etc.
Broadly, for a 60 KLD distillery, ₹25-30 crore would be the initial investment towards plant and machinery with a payback period of < 3 years.
Know-how transfer of the process; License fee and other financial details would be made available on specific request.
