Industrial symbiosis model in leather processing industry center

One of the manufacturing industries that has the potential to have an impact on the environment is the leather processing industry. The leather tanning industry is an industry that converts raw animal skins into tanned leather. This leather is then used as raw material for the manufacture of various leather products such as shoes, bags, jackets, sandals, belts, and other leather crafts. The leather tanning industry produces liquid and solid waste that has the potential to cause negative impacts. impact on the environment. Meanwhile, industries that make leather products produce solid waste in the form of patchwork. To overcome this problem, there is an industrial symbiotic approach which is a form of cooperation between different industries. This form of cooperation can increase the profits of each industry and ultimately have a positive impact on the environment. This study aims to establish a pattern of cooperation between the leather tanning industry and the leather processing industry to minimize the waste generated. The results show that the implementation of industrial symbiosis can be carried out by five leather processing business actors, they cooperate in the processing of the waste produced so as to minimize waste that has economic value.
