Feedstock categories

Bio-Fission assesses feedstock before recommending a plant concept. Suitability and yield are never guaranteed without project-specific evaluation.

Cattle Dung

Widely used for biogas and CBG projects, particularly in dairy clusters, gaushalas, livestock farms and rural agri-business regions.

Planning considerations

  • Daily dung availability and collection reliability
  • Moisture content and slurry preparation
  • Transport distance and collection logistics
  • Sand, grit, straw and impurity management
  • Seasonal variation in livestock availability

Project application: Dairy clusters, gaushalas and livestock farms

Agricultural Residues

Crop residues such as paddy straw, wheat straw and cane trash can be considered, often alongside dung or other organic waste.

Planning considerations

  • Seasonal availability and storage requirement
  • Bulk density, handling and chopping
  • Moisture content and pre-treatment needs
  • Transport cost and collection radius
  • Competing uses for the residue

Project application: Co-digestion with dung or other organic waste

Food Waste

Food-processing, kitchen, and fruit and vegetable waste can suit anaerobic digestion when properly segregated and handled.

Planning considerations

  • Segregation and contamination control
  • Daily quantity and seasonal variation
  • High-moisture handling and odour management
  • Packaging and plastics removal
  • Waste collection and processing regulations

Project application: Food processors and kitchen-waste generators

Press Mud

A by-product of sugar milling that can be evaluated for biogas and CBG plants, particularly for sugar mills and allied businesses.

Planning considerations

  • Quantity and consistency of generation
  • Moisture content and storage conditions
  • Transport and handling requirements
  • Co-digestion potential with other feedstocks
  • Digestate management and nutrient recovery

Project application: Sugar mills and allied businesses

Poultry Litter

May be considered with appropriate pre-treatment and process design.

Planning considerations

  • Litter quantity, moisture and bedding material
  • Ammonia and nitrogen-related process considerations
  • Storage, odour and biosecurity requirements
  • Transport distance and handling system
  • Digestate management and nutrient content

Project application: Poultry farms and livestock-based businesses

Hybrid Napier

A fast-growing perennial grass with strong biomass potential and regrowth after harvesting, considered as an energy crop or co-feedstock.

Planning considerations

  • Variety and cultivation conditions
  • Harvesting frequency and logistics
  • Chopping and pre-treatment
  • Land, water and agronomy support
  • Digestion performance

Project application: Energy crop or co-feedstock where land and water support reliable supply

Feedstock selection and supply planning

A robust plan covers more than quantity.

  • Assessed daily and annual quantity
  • Seasonal calendar and buffer storage
  • Collection radius and transport cost
  • Quality, moisture and contamination control
  • Supplier agreements or aggregation model
  • Backup feedstock options
  • Pre-treatment and handling requirements
  • Digestate disposal or value-recovery plan

Other potential feedstocks include selected municipal solid waste fractions, sewage treatment plant waste, market waste, dairy-processing waste, distillery-related organic streams and suitable industrial biodegradable waste, depending on composition, contamination and regulatory permissions.

Products and outputs

CBG is the primary product. Digestate may add value where it meets quality and regulatory requirements.

OutputPotential applicationQuality considerations
CBG / Bio-CNGCompatible vehicles, industrial fuel, captive energyMethane content, moisture, H₂S, impurities, pressure, applicable fuel standards
Solid digestateOrganic manure, soil-conditioning applicationsMoisture, maturity, pathogen and contaminant limits, fertiliser regulations
Liquid digestateNutrient recovery, irrigation or agricultural useNutrient content, pH, treatment needs, crop suitability, regulations
