Method 6 (ABP Processing)

Method 6 ABP processing involves specific procedures for treating animal by-products, particularly those from aquatic animals, to ensure they are safely managed and utilised according to EU regulations.

Method 6 ABP processing, as defined by EU regulations, is a vital method for managing Category 3 animal by-products originating from aquatic animals or aquatic invertebrates. This method includes:

Particle Size Reduction: The animal by-products must be reduced to a particle size no greater than:
- 30 mm if heat treatment is applied according to point 2(b)
- 50 mm if heat treatment is applied according to point 2(a)
- After reduction, the by-products must be mixed with formic acid to reduce and maintain the pH to 4.0 or lower. The mixture must be stored for at least 24 hours pending further treatment.
Heat Treatment: The mixture must then be heated to:
- A core temperature of at least 70°C for at least 60 minutes.
- A core temperature of at least 90°C for at least 60 minutes; or
- When using a continuous flow system, the progression of the product through the heat converter must be controlled by mechanical commands limiting its displacement, ensuring a sufficient cycle of time and temperature.
Batch or Continuous Systems: The processing may be carried out in 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.
