Feedstock Options for Biogas Plants: Yield, Cost & Quality
Compare feedstock types for maximum biogas yield and consistent digester performance. Learn yield rates, costs, and optimal feedstock blending strategies.
Feedstock selection directly impacts biogas plant economics. Different organic materials have vastly different methane yields, cost structures, and seasonal availability. Strategic feedstock blending maximizes digester stability and revenue.
High-Yield Feedstock
Food waste: 250-450 m³/ton, ₹3-5/kg, high variability - Best for: Urban facilities, food processing industries - Challenge: Moisture management, odor control
Maize silage: 220-300 m³/ton, ₹8-12/ton, consistent quality - Best for: Agricultural regions, cooperative models - Advantage: Stable C:N ratio, predictable yield
Distillery spent wash: Variable yield by feedstock, ₹10-20/1000L, energy-dense - Best for: Sugar & alcohol industries, high-protein digestion - Challenge: Seasonal bottlenecks, storage requirements
Medium-Yield Feedstock
Napier grass: 180-220 m³/ton, ₹500/ton fresh weight - Best for: Smallholder farmers, perennial supply - Advantage: Continuous growth throughout year
Press mud: 90-120 m³/ton, ₹1/kg, nutrient-rich - Best for: Sugar mills, industrial co-location - Challenge: Seasonal variation (crushing season)
