Many of the large-scale distilleries manage their spent wash through concentration-incineration route, in accordance with prevailing MoEF&CC/CPCB guidelines & generate high volume of potash-rich ash. In comparison to other competing technologies for utilisation of such ash (viz., production of PDM or Mixed potassic salts utilizing distillery ash); the present technology enables production of premium grade SOP (100% water soluble - suitable for drip irrigation & foliar application), & thus offers (i) wider product acceptance in national & global context – particularly for high value crops, as well as (ii) relatively better profitability.

Applicable for utilisation in distilleries generating potash-rich ash, primary market being India, Thailand, Brazil etc.

Premium grade SOP (100% water soluble - suitable for drip irrigation & foliar application), offers (i) wider product acceptance – particularly for high value crops, as well as (ii) relatively better revenue & profit.

In Indian context, this technology can potentially generate   more than 1.5 lakh tpa indigenous potash fertilizer (import substitution) on across-the-sector technology adoption (with more than 100 distilleries generating K-rich ash).

Environmentally safe & benign process; Implementation of the process would lead to better environment with respect to particulate nuisance around the distilleries.

Distillery incinerator ash, minor process chemicals & reagents.

Generic equipment used in chemical process plant, viz., stirred tanks, evaporators, filters, centrifuges, pumps etc.

Broadly, for a 15 tpd SOP plant, ₹45 crore would be the initial investment towards plant and machinery with a payback period of about 4 years.
