Vegetable tanning is considered less environmentally hazardous. Yet, there have been no plans to promote it in South Africa. Vegetable tanning process utilises vegetable matter for converting animal skins or hides into pliable material that is known as leather. South Africa has a variety of plants that produce tannins. However, the focus of this study is on the mimosa locally known as black wattle (Arcacia miernsii). Furthermore, the South African vegetable tanning sector has been left behind in terms of research and development despite the country being endowed with the Mimosa plant that is widely used in the vegetable tanning process. The country is also endowed with surplus labour which can be absorbed by the leather industry which is labour intensive.
