Vidhata CBG Napier Feedstock & Harvesting Calculator

CBG Napier Feedstock & Harvesting Calculator

Calculate harvesting requirements, rainy-season silage buffer, bunker CAPEX and separate operating expenses (OPEX).

1. CBG Plant & Harvesting Inputs

Normally 52 Sundays/year.
3 months ≈ 90 days.
Automatically changes with selected configuration.
Maximum 8 hours/day per machine. The machine requirement is calculated using this limit.

2. Silage & Bunker Assumptions

Default: 800 kg/m³ compacted silage.
Default: 8 ft maximum silage height.
6-inch concrete base floor; default ₹300/ft².
Default ₹200/ton for filling and compaction.
Bunker floor CAPEX is calculated on the theoretical floor area required for the buffer. Filling and compaction cost is calculated on the fresh Napier buffer quantity. No silage-loss allowance is included.

3. Operating Expenses (OPEX) Assumptions

JF 1150/JF 1600 = 11 L/hr; JF C120 = 7 L/hr. Automatically set by machine selection.
For trolley/logistics support. Set to 0 if not required.
Excludes diesel and driver salary.
Applied to the total fresh Napier tonnage handled.
OPEX is calculated separately from CAPEX. Driver and side-tractor fixed costs are counted on effective harvesting days. Diesel is based on operating hours, and maintenance is calculated at the selected ₹/ton rate against annual feedstock demand.

Storage note: Bunker area is a theoretical floor footprint calculated as compacted silage volume divided by bunker height. Actual civil design should allow additional space for walls, drainage, access roads, loading/unloading and operating clearances. CAPEX note: All machine and civil rates are indicative planning assumptions and should be confirmed through a project quotation. The ₹300/ft² floor rate represents a 6-inch concrete base-floor assumption supplied for this calculator.
