This paper deals with a new tanning process based on improving the efficiency of chemical use in order to improve the environmental behaviour of tanneries. This process develops a non-float system with a minimal amount of NaCl, reduced chrome salt addition and increased final tanning temperature at 55°C. The properties of the leathers were similar to those from a traditional process. However, the new process gave 97 % less residual chrome and a 95 % decrease in the chlorides discharged. Moreover, the new process involves 100 % savings in water, about 78 % in NaCl and about 32 % in Cr2O3 addition. Consequently the process is 55 % more cost-effective than the traditional process.
