Leather tanning industry is one of the industry which potentially causes environmental problem. For processing, a lot of water and chemical are used, generates a lot of liquid waste, which are powerful pollution in water an in soil. There will also be animal residues from such operation as cleaning, fleshing, splitting and trimming. Each of these generates solid waste which must be disposed. It is a big problem for handling the solid waste because of their volume and highly odours when they decompose in their solid form. Untanned solid waste and liquid waste generated in the tanning process have a high organic content (protein and fats) and their humidity …. are such that they are readily degradated by methane fermentation.
