Division 2 Processing method

Thermomechanical biofuel production shall be carried out according to the following processing standards:

1. (a)

   The animal by-products must be loaded into a converter and subsequently treated at a temperature of 80 °C for a period of eight hours. During this period, the material must be constantly reduced in size using appropriate mechanical abrasion equipment.

2. (b)

   The material must be subsequently treated at a temperature of 100 °C for at least two hours.

3. (c)

   The particle size of the resulting material must not be larger than 20 millimetres;

4. (d)

   The animal by-products must be treated in such a manner that the requirements regarding time, temperature and pressure set out in points (a) and (b) are achieved at the same time;

5. (e)

   During the heat treatment of the material, evaporated water must be continually extracted from the air-space above the biofuel and must be passed through a stainless steel condenser. The condensate must be kept at a temperature of at least 70 °C for at least one hour before being discharged as wastewater;

6. (f)

   After the heat treatment of the material, the resulting biofuel from the converter must then be discharged and automatically conveyed by a fully covered and interlocked conveyor to incineration or co-incineration on the same site;

7. (g)

   The process must be carried out in a batch mode.
