The demand for chrome-free, heavy metal free and glutardialdehyde (GDA) free leather is bigger than ever. Zeology, an innovative leather tanning agent based on zeolites, delivers just that.

To ensure that you are working with “the real thing” and not just any zeolite-based tanning agent. Zeology is the only zeolite-based tanning agent for optimal leather performance on any substrate with a low environmental impact and unmatched production consistency.

The uniqueness of Zeology

What makes Zeology unique, compared to both traditional tanning agents and other existing sustainable alternatives, is that it delivers both sustainability benefits and superior leather performance.

Zeo White, the Zeology-tanned leather intermediate, is unsurpassed in characteristics such as grain tightness, physical leather properties, lightfastness and heat resistance. In addition, its bright white colour enables white leather and lighter and brighter colours than were ever possible before.

Four reasons why Zeology ≠ zeolite

Leather performance

Zeolite as an unmodified raw material, sold by the kilogram, is not a suitable tanning agent. The only perceived advantage of these zeolite blends is the price per kilogram of the tanning agent. Conversely, Zeology, with a modified zeolite (patented), is developed for optimal leather performance on any substrate with low environmental impact and unmatched production consistency.

Certifications

Zeology is the certified leather tanning agent that is proven free of hazardous chemicals and consists of circular chemistry. So far, Zeology is the only zeolite-based tanning agent with ZDHC MRSL Conformance (Level 3), C2C Certified Material Health Certificate at the Platinum level and a ToxFMD Screened Chemistry certification.

Proven results

Zeology-tanned leather is biodegradable and compostable and is already being used worldwide for the creation of leather items, from shoes to bags and car seats, and many more beautiful and responsibly crafted products. PUMA, Anya Hindmarch, Mart Visser, EMMA Safety Footwear and Italic are just a few brands that have created leather goods with Zeology leather.
