Detailed program

What you will learn

Composting module

1. Characterize the feedstock
  • Identify biowaste and its sources
  • Quantify by weighing and production ratios
  • Sample (quartering) and calculate DM, OM and C/N
2. Understand composting
  • Biological phases and sanitization
  • Control temperature, moisture, aeration, C/N and pH
  • Choose the process: bins, windrows, aerated piles, in-vessel
3. Size a unit
  • Formulate the mix (C/N and moisture)
  • Size bins or windrows, area and water needs
  • Mass balance and compost output
4. Set up and build the pile
  • Lay out the composting area and manage leachate
  • Equipment and PPE
  • Build a homogeneous, aerated pile step by step
5. Monitor composting
  • Operator dashboard
  • Read temperature curves
  • Diagnose and fix problems
6. Obtain quality compost
  • Maturation and screening
  • Stability and maturity tests (cress test)
  • Lab analysis before sale
7. Use and test compost
  • Doses and application by crop
  • Run a pot or field trial
  • Measure, compare and conclude

Anaerobic digestion / biogas module

1. Characterize biowaste
  • What can be digested… and what cannot
  • Key measurements: DM, OM, C/N
  • Methane potential (Buswell, BMP test) and inhibitors
2. Choose and size the digester
  • Low-tech digester families and selection criteria
  • Volume, organic loading rate, retention time, dilution
  • Biogas production and storage by end use
3. Design, build and purify
  • Complete layout of a continuous digester
  • Construction plan and materials
  • Biogas purification (water, H₂S, CO₂) and safety rules
4. Inoculum and feedstock mix
  • Why and how to seed
  • Prepare an inoculum
  • Balance the co-substrate mix
5. Start up and monitor
  • Start-up and ramp-up phases
  • Dashboard, pH and FOS/TAC titration
  • Diagnose and fix
6. Treat and prepare digestate
  • Digestate composition
  • Phase separation, sanitization, storage
  • Limit nitrogen losses
7. Apply digestate to crops
  • Calculate the dose to crop needs
  • Application methods and calendar
  • Check safety (germination test)
