- The Sugar mills can now sell potash derived from molasses (PDM) to fertiliser companies to earn additional revenue.
- And also, they can receive nutrient-based subsidies on it.
- PDM, a potassium-rich fertiliser, is a by-product of the sugar-based ethanol industry.
- It is derived from ash in molasses-based distilleries.
- India currently imports 100% of the potash it needs for fertilisers, in the form of muriate of potash (MOP).
- Distilleries produce a waste chemical called spent wash during ethanol production, which is burned to produce ash.
- This ash can be processed to produce PDM, which has 14.5% potash content.
- This can be used by farmers as an alternative to MOP, which is 60% potash.
