Tannery Flesh Waste Transformed into Sustainable Leather Coating

Extracting fat from tannery flesh waste yields a stable substance that enhances leather aesthetics and offers a sustainable alternative to synthetic polishing materials.

Textile & Leather Review · 2023

Key Findings

01The extracted fat from tannery flesh waste exhibited a stable saponification value (189-192), indicating its triglyceride content suitable for lubrication and polishing.
02Application of the extracted fat to leather products resulted in improved aesthetic properties, specifically increased lustre and gloss, providing excellent polishing results.
03The extracted fat demonstrated stable chemical and physical properties, making it a promising candidate for functional leather coatings.

Application

Design takeaway

Consider waste streams from related industries as potential sources for novel materials with functional properties, particularly for surface treatments and aesthetic enhancements.

How to apply

Investigate the chemical composition and physical properties of waste materials from your specific industry or related sectors to identify potential for extraction and repurposing into functional design components or finishes.

Project actions

01When choosing a waste material, consider its abundance and accessibility.
02Thoroughly research the chemical composition of the waste to predict potential extractable substances and their properties.

Method & Evidence

AimTo investigate the feasibility of extracting a functional and aesthetically enhancing substance from tannery flesh waste for use as a leather coating.

MethodExperimental research and chemical analysis.

ProcedureTannery flesh waste was washed, de-limed, and cut. Fat was extracted using a Soxhlet apparatus with hexane as a solvent. The extracted fat was chemically analyzed for properties such as saponification value, acid value, melting point, density, and viscosity. Its performance as a polishing agent on leather products was then evaluated.

ContextLeather tanning industry, materials science, sustainable product development.

Variables

IVTannery flesh waste (source material).

DVAesthetic properties of leather (lustre, gloss), chemical stability of extracted fat.

CVSolvent used (hexane), extraction method (Soxhlet apparatus), type of leather tested.

Strengths & Limitations

Strengths

+Addresses a significant environmental issue with a practical solution.
+Provides detailed chemical analysis of the extracted substance.

Limitations
