The article outlines the range of specialized leather processing tanneries processes. They are the backbone of the leather industry. The difficulties these plants face are indicated, and wastewater parameters are given and compared with literature data, confirming that they are a problem for many plants. Good water and wastewater management practices to improve environmental aspects are also described. The data on the leather industry from recent years were analyzed in terms of economics, showing that the outlook for the industry is not optimistic.
