Leather tanning industries are industries that process skin to produce finish leather product by using many stages of process in which for every stage of process will generate a huge amount either liquid or solid waste. If waste are not to be treated properly, it will cause environmental pollution. Implementation of 3R programs i.e. recycle, reuse and recovery will give impact on minimizing of waste problem. In leather tanning industries for producing wet blue leather however, 3R programs have to be implemented in processes of desalting, washing liquor, flesh and fat, chrome liquor and chrome-tanned waste. In implementing 3 R the waste generated can be either reused, recycled or recoveried as follow salt as swelling agent preventing in pickling process; washing liquor waste as washing liquor for dirt washing; flesh and fat as raw material for producing tallow, soap, fertilizer and livestock fodder; chrome liquor waste as chrome agent for chrome tanning and chrome-tanned waste as filler for producing material building or livestock fodder as protein sources.
