Waste to wealth approach: adhesive from the unused goat head skin

Slaughterhouse byproduct management is an important issue for the green environment. The byproduct from the slaughterhouse e.g. cow, buffalo, goat and sheep skin is the basic raw materials for the tanning industry. After slaughtering cow and buffalo head skin is used in small scale for leather processing. But in the case of goat and sheep, the head skins are disposed away without any proper management to the environment from where gaseous air pollutants are continuously merged to the atmosphere. In this study, an investigation was carried out for the adhesive production for commercial use from the unused goat head skin by means of a cleaner environment. Goat head skin was collected from the local slaughterhouse: soaked and heat treated to extract the collagen in soluble phase. The extracted solution was dried and obtained adhesive was investigated for commercial application. The produced adhesive could be used in the packaging industry, furniture, plumbing, shoe making, book binding, etc. Adhesive was prepared from the goat head skin by using the simple and easy technique with a few chemical. It was estimated that Bangladesh could produce 625 MT adhesive per year only from the unused goat head skin.
