Improvement of Fermentation and Distillation Operations.
Crest’s System Consist of recycling of spent lees, partial spent wash and evaporators condensate.
The existing Biomethanation is improved to load digester @ 10 – 15 kg COD/M3 / day without dilution.
The overflow of Biomethantion is concentrated employing multiple effect evaporator ( MOC MS and Tubes SS 304 ) and concentrated effluent of 50 – 55 % TS is obtained.
This concentrated effluent is mixed with agro-residues and is dried to free flowing “Mix Fuel”
 
This mix fuel is burnt in boiler to generate steam.
The Energy Steam Balance is given
There is no requirement of secondary treatment.
It is a zero pollution system.
