                  Production of synthetic fatty acids, on a limited scale, has been resumed by Deutsche Fettsäurewerke at Witten since small amounts of Fischer-Tropsch Gatsch have been received with the restarting of the Fischer-Tropsch plants at Castrop-Rauxel and Wanne-Eickel.  These Witten works were idle from the end of the war until September 1947.
