However, a considerable fraction of the raw material is discarded or sent to other industries because of its composition or limited value in terms of leather manufacturing. Many studies were conducted to reduce, reuse, recycle or dispose of tanning process waste. Alternatives are being implemented to ensure the adoption of environmentally safe methods that meet environmental laws, and to raise the awareness of the professionals involved in the sector. Brazil reportedly has the largest commercial cattle herd in the world, is the largest producer of bovine cattle in the world and the world's third largest producer and exporter of leather. Other significant data, as well as other indicators of the sector are presented. The present study characterizes the brazilian industry regarding the leather articles produced, where the footwear articles are the main end-use of leather. A study in 224 brazilian tanneries was performed with the purpose of finding out which are the most widely used tanning processes. A typical representation of the wastewater treatment technology most frequently adopted in Brazil comprises the stages of preliminary treatment, mechanical and physical-chemical treatment, biological treatment, sludge treatment or disposal and nitrogen removal. the most advanced wastewater treatments and water reuse in tanneries, also the main uses for by-products generated in the leather processing are presented and discussed. The work summarizes the research lines and developments conducted at the UFRGS, at the Laboratory for Leather and Environmental Studies, in order to obtain information on the lastes technologies and improvements in the leather sector.
