Vegetable-tanned Leather And Environmental Protection

What is Vegetable-Tanned Leather?

Vegetable-Tanned Leather is a type of leather tanned using natural plant extracts. It has the advantages of being natural, environmentally friendly, and biodegradable, and is widely used in high-end handmade leather goods and art products.

Plant Tannins, No Heavy Metals

Uses natural plant tannins to avoid chemical pollution.

Naturally Biodegradable (3–5 Years)

Returns to the natural cycle after the end of its life cycle.

Low Carbon Footprint
Green Production

Natural materials that consume less energy.

Tannins, Nature’s Gift

Tannin is a natural substance present throughout the plant kingdom: in wood, bark, rhizomes, roots and fruits.

Historical Context of Vegetable-Tanned Leather

Vegetable tanning technology can be traced back to around 6000 BC. The ancient Egyptians began to use plant extracts to preserve and soften leather. As civilization developed, medieval Spain became the center of vegetable tanning in Europe, using the “pit tanning method” to soak raw hides in plant liquid for 6–12 months.

After the Industrial Revolution in the 19th century, Tuscany in Italy introduced the drum tanning technology, shortening the tanning cycle to 60–90 days while retaining the natural process. This innovation not only improved production efficiency but also maintained the natural characteristics of vegetable-tanned leather, laying the foundation for modern vegetable tanning processes.

100% of leather scraps recycled for reconstituted leather products or industrial grease production Circular Economy

Environmental Advantages

“The environmental value of vegetable-tanned leather lies not only in its natural ingredients but also in the ‘less is more’ consumption concept it advocates. A high – quality vegetable-tanned leather product can accompany the user for decades, which in itself is the most environmentally friendly choice.”
