牛皮是一种宝贵的资源，然而直到今天，它的利用率仍十分有限。每年只有约40%的牛皮用于正面革的生产，而有相当大的一部分被填埋或被当作废物处理了。将来，肉食加工工业的变化会冲击到制革工业，牛皮这一宝贵资源的潜能可以得到更充分地利用。信息微处理机的发展将会使加工过程进一步改善可以使动物从出生到被宰杀这段时期的生长历程和特点得以记录，甚至还可对制革的全过程进行控制。同时，人们预言未来50年内占统治地位的鞣剂仍然是铬鞣剂，但不管怎样，新的鞣制体系迟早会代替铬鞣法。

The future of leather industry(I) Fully utilization of the resource of cattle hide, an epoch-making revolution in leather industry

Cattle hide is a kind of precious resources, but its utilization is rather limited even in today.Only 40% of cattle hide been processed into leather and a big part has been buried or processed as waste. In future, the change in meat industry will have impacts on leather industry, and thus cattle hide can be fully utilized. The development of information microprocessor will further improve the process. For example, the features of cattle in different periods can be recorded, and the whole process of leather making can also be controlled. Meanwhile, it was predicted that chrome tanning agents will deminate for the next 50 years, but nevertheless a new tannage will finally replace chrome tannage.
