Division 1 The following processes may be used to produce fat derivatives from rendered fats derived from Category 1 and Category 2 material:

F1transesterification or hydrolysis at a temperature of at least 200 °C, under corresponding appropriate pressure, for at least 20 minutes (glycerol, fatty acids and esters);

saponification with NaOH 12M (glycerol and soap):

1. (i)

   in a batch process at 95 °C for three hours; or

2. (ii)

   in a continuous process at 140 °C 2 bars (2 000 hPa) for eight minutes; or

hydrogenation at 160 °C at 12 bars (12 000 hPa) for 20 minutes.
