WASTE FROM THE LEATHER INDUSTRY – A RESEARCH IN CURRENT CONTEXT
Abstract
The „take-make-trash" economic model of today increases the generation of waste and the consumption of raw materials, both of which have a negative impact on the environment when handled improperly. One of the most provided by the natural and contamination businesses is the leather manufacturing. The leather industry produces a lot of trash, which should be handled according to the circular economy's guidelines. Each leather manufacturing facility produces a sizeable amount of effluent with high pollutants that, if discharged into the environment without being properly treated, have a negative effect on the ecosystem. According to estimates, waste generated during the manufacturing of leather outweighs output of all products by 200 times. This article provides some insight regarding the types of waste and the water pollution due to the leather industry. Many secondary wastes can be recovered through these some processes and used in other industrial processes. Also, the article presents aspects related to the recovery and recirculation of industrial water from the leather industry.
