The leather without chrome, and on solid state, is a protein with high value for agriculture, the organic-free protein chrome is utilized as raw material for the chemical industry. Organization of the United Nations, the environmental problems related to leather processing, that demands hazardous chemical products such as chrome, are increasing.

On this pattern Alimet al. The industry currently uses certain standards based on the physical characteristics of intermediate and final product such as shrinkage, shrinkage temperature and thermal stability thus many attempts to improve the thermal properties of free chrome leather was done demonstrated that using oxazolidine [5] or resorcinol tanning agents combined with other vegetable or synthetic agents allows for the obtaining of quality leathers that can be used by footwear and upholstery industries [6].

Making leather is a complicated process. The easiest way to understand the tanning process of leather preparation is to understand the layer separation in which the leather is split across its thickness to produce a top layer hair side and the under layer. The top layer is called full grain and describes the side exposed to the elements giving it the durability and malleability it needs to be considered fine leather. The underside is much stiffer and less durable than the top layer. This is practical for use after a coating or treatment is applied.

Leather goods are prized for their beauty and durability, but tanning leather uses and pollutes large amounts of water. With care, leather goods tend to be tougher a1nd more durable than nylon, canvas, or various imitation leather products, but their desirability transcends function and enters the world of beauty and style. But durability and beauty come at an environmental price. Although the total water footprint of the leather industry does not rival an industry like the hydroelectric power sector in absolute numbers, the leather tanning industry, for its size, is one of the most water-intensive industries across the globe, from the water used to raise animals to the water used in tanning and finishing processes.

Conventional chrome tanning methods employed in the leather processing industry subject the hides and skins to treatment with a wide variety of chemicals and passage through various unit operations. All this involves an enormous amount of time and they contribute to an increase in COD, chlorides, sulfates and other mineral salts, which end up as effluent. But, perhaps more alarmingly, the process uses profuse quantities of water in areas where there is rapid depletion of ground water.
