What could happen if a textile mill moved from diesel to biomass?
Let's take an illustrative example.
A textile mill is spending around ₹30 lakh every month on diesel for process heating. That's approximately ₹3.6 crore annually.
Now after a suitable biomass retrofit, the estimated monthly fuel cost comes down to around ₹18 lakh.
That would mean potential savings of approximately ₹12 lakh per month, or ₹1.44 crore annually.
If the retrofit investment is around ₹50 lakh, the simple payback based on these assumed numbers could be approximately 4 months.
But this is where proper ROI calculation becomes important.
Actual economics depend on diesel and biomass prices, fuel consumption, operating hours, heat demand, biomass quality, system efficiency, retrofit requirements, maintenance, and the plant's operating conditions.
The point is simple:
Don't ask only, "Is biomass cheaper?"
Ask:
"What will my complete cost of heat be, and what will my return on investment look like?"
That's where a fuel conversion decision becomes a business decision.
