Abstract:
Cleaner production (CP) options for leather manufacturing in Hebron are identified and eval uated for the purpose of examining their potential adoption. The approach was descriptive
combined with field sampling and laboratory testing from seven factories. All processes in the
investigated factories have been monitored, focusing on chromium contamination in wastewa ter (WW). In addition, pollution sources from every process have been identified, in a parallel
paper, and used in this analysis. The determined process efficiency of tanning is found to be
low to medium, compared to that reported in previous work. The evaluation of the identified
CP options indicates that the most practical options is the improvement of operating conditions
of the tanning process, such as pH, for increasing chromium uptake efficiency. This requires
further experimental study to investigate the technical feasibility, industrial acceptance and the
impacts of process modifications on the quality of the produced leather
