Method 4 ABP processing involves detailed procedures to handle and treat animal by-products safely and efficiently, ensuring compliance with EU regulations.

Method 4 ABP processing is outlined in the EU regulations as a crucial method for managing animal by-products (ABP) effectively. This method includes:

  • Particle Size Reduction: Animal by-products must be reduced to a particle size no greater than 30 millimetres using appropriate equipment. The effectiveness of the equipment must be checked daily, and any necessary repairs must be made if discrepancies are found.

  • Heat Treatment: After reduction, the animal by-products must be placed in a vessel with added fat and heated to achieve specific core temperatures:

    • Greater than 100°C for at least 16 minutes

    • Greater than 110°C for at least 13 minutes

    • Greater than 120°C for at least 8 minutes

    • Greater than 130°C for at least 3 minutes

  • Batch or Continuous Systems: The processing can be carried out in either batch or continuous systems, allowing flexibility in operations.

  • Regulatory Compliance: Adherence to these processing standards ensures that the treated ABP is safe for its intended use, whether for energy production, fertilisers, or other technical applications.

Method 4 ensures the safe and effective treatment of ABP, minimising risks to public and animal health and adhering to stringent EU regulations.
