The ice and snow on the streets this winter have pushed up the demand for rock salt,which means the salt business is booming.Every day 20,000 tons of salt are mined from the pits of the Heilbronn salt works in southwest Germany. Eight hundred trucks loaded with the valuable mineral roll out of the yard daily. The workers are on round-the-clock shifts. But the salt shortage persists. Report by Grit Hofmann.
