Modified zeolites as sustainable alternatives to traditional tanning chemistries

Leather is the largest application of collagen where typical tanning chemistries include metal salts, polyphenolics and aldehydes. A new type of material that is gaining industrial significance is based on a composite of collagen and zeolite in the area of sustainable leather manufacture. This approach utilises simple, abundant, and benign chemistry, which provides leather with the physical properties needed for a range of possible applications.

In this research article, published in the journal Green Chemistry, scientists from University of Northampton, Royal Smit & Zoon and NZ Leather Research, give a deeper insight on modified zeolites (Zeology) as a versatile and sustainable means to move away from established tanning methods.

“A new material gaining industrial significance for sustainable leather is based on a composite of collagen and zeolite. The zeolite forms a 3D network structure covering collagen fibres, improving protein stability and creating material strength.” – Green Chemistry
