Waste Management
Organic Waste Management: From Farm to Fertilizer Revenue
Transform agricultural and industrial organic waste into high-value products. Discover waste-to-resource systems that generate energy and premium fertilizer.
Organic waste represents untapped economic potential. Agricultural residues, food processing waste, and animal manure are conventionally burned or landfilled, generating methane emissions. Modern waste management systems recover energy and nutrients, creating circular value chains.
Types of Organic Feedstock
Agricultural: Napier grass, maize silage, crop residues (180-220 m³ biogas per ton) Industrial: Press mud, distillery spent wash, food waste (90-450 m³/ton) Animal: Cattle dung, poultry litter (50-180 m³/ton)
Blending feedstock types optimizes digester performance and biogas yield.
Waste-to-Energy Process
- Collection & preprocessing: Feedstock aggregation and size reduction
- Anaerobic digestion: Bacterial decomposition in controlled reactors
- Biogas extraction: Methane capture and purification
- Digestate processing: Nutrients recovery and fertilizer curing
Each ton yields 15-25 kg nitrogen-rich organic fertilizer alongside energy.
Revenue Streams
Primary: Energy sales (CBG at ₹75/kg or electricity) Secondary: Fertilizer sales (₹5-8/kg premium organic compost) Tertiary: Carbon credits and government incentives
