The Central Pollution Control Board (CPCB) has prescribed and implemented zero discharge norms from distillery effluent for the distillery industry with effect from 1-1-2006. the Board had provided about three years time to the distillery industry to achieve zero discharge through any process of distillery effluent treatment suitable to each distillery. This was prescribed under charter on Corporate Responsibility for Environmental Protection (CREP) Programme of the Government of India introduced by the CPCB.
In this regard, the Central Pollution Control Board had prescribed protocol for achieving zero discharge through (i) ferti-irrigation (ii) one time application and (iii)biocompositing of distillery effluent with press-mud. We provide here below copies of the protocols issued by the CPCB, on our website (under section A) for the benefit of our member
The Food Safety and Standards Authority of India (FSSAI) has been established under Food Safety and Standards Act, 2006 which consolidates various acts & orders that have hitherto handled food related issues in various Ministries and Departments. FSSAI has been created for laying down science based standards for articles of food and to regulate their manufacture, storage, distribution, sale and import to ensure availability of safe and wholesome food for human consumption. read more »
Utilization of SW with different levels of treatment and dilution is permissible both for irrigation of standing crops, ferti-irrigation, and once a year land application before sowing of a crop.pre-sown irrigation. read more »
Any Distillery desirous of utilizing SW for pre-sown irrigation shall use biomethanated SW of BOD less than 7.000 mg/l.
The biomethanated effluent shall be temporarily stored in the lagoons described in 1.4 and 1.5 from where it will be withdrawn for application.

The stored SW in the lagoons shall be analyzed every 15 days. Samples will be taken at the points from where the SW will be withdrawn for irrigation and analyzed for pH, EC,TDS, Ca+, Mg+, Na+, K+, C1, SO4 , CO3+ HCO3, BOD and TKN. Based on these analyses composite irrigation water quality parameters % Na+, adj SAR and RSC, will be calculated. read more »
Seasons, particularly the rainy season, and the sowing periods of the crops, put restrictions on the utilization of SW for irrigation. Ferti-irrigation may be carried out in rainy season in areas where the rainfall is less than 100 cm/year. Where the rainfall is between 100 and 200 cm/year, irrigation may be required only during the dry spells of the rainy season. read more »
Co-processing of wastes in cement kiln is emerging as one of the environment friendly alternative disposal method in the recent years. Distillery spent wash has high organic content and dissolved inorganic solids which require careful handling and proper disposal to avoid damage to the environment. Presently it is being used on to land to provide nutrient value, though it contaminates both the ground water and surface water sources, as most often it is practiced in non-scientific manner. read more »
