A new process by Austrian plant manufacturer BDI-BioEnergy (BDI) has been approved for the safe disposal of high-risk fat material, the company announced on 20 April.

The RepCAT process was based on patented technology using a recyclable catalyst in biodiesel production, BDI said.

The European Food Safety Agency (EFSA) had approved the process, which meant it could be used to produce biodiesel from highly contaminated animal fats, the company added.

The positive assessment had been based on joint trials with the University Medical Center Hamburg-Eppendorf.

Three large-scale biodiesel plants were currently being built in the USA and Europe using the RepCAT technology.

BDI-BioEnergy International builds customised biodiesel plants based on multi-feedstock processes developed and patented in-house.
