Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Leather manufacturing processes face challenges in achieving sustainable practices due to the use of synthetic petro-based compounds, which have high environmental impact, toxicity, and non-biodegradability, leading to pollution and emissions.
Innovation Solution
Employing pectin in the leather manufacturing process as a biodegradable alternative to synthetic petro-based compounds, such as vinyl polymers, to enhance organoleptic and mechanical properties, and reduce environmental impact by using pectin in the form of an aqueous solution during post-tanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If synthetic petro-based compounds (vinyl polymers) are used in leather manufacturing, then organoleptic and mechanical properties of leather are improved, but environmental impact increases and biodegradability decreases
Solution Approach 1:
The patent changes the chemical composition parameter from synthetic petro-based vinyl polymers to natural biodegradable polymers (pectin, starch, cellulose, chitosan, gelatin, or their blends). This substitution maintains the polymer function of improving leather mechanical properties while eliminating the harmful environmental factors associated with petrochemicals and non-biodegradability
Solution Approach 2:
The patent employs inexpensive natural polymers that are biodegradable and environmentally friendly as alternatives to expensive synthetic petro-based polymers. These natural polymers can be derived from renewable resources and are designed to decompose naturally, reducing long-term environmental burden while maintaining effective leather treatment
2Reliability
If synthetic petro-based compounds are used in leather manufacturing, then leather performance is optimized, but toxicity and environmental pollution increase
Solution Approach 1:
The patent changes the chemical nature parameter from toxic synthetic compounds to non-toxic natural polymers. The specified natural polymers (pectin, starch, cellulose, chitosan, gelatin) are inherently biocompatible and non-toxic, thereby maintaining reliable leather performance while eliminating toxicity and environmental pollution issues
Solution Approach 2:
The patent converts the previously harmful synthetic polymers into beneficial natural polymers that offer both leather performance optimization and environmental benefits. The natural polymers provide the necessary functional properties for leather treatment while simultaneously reducing toxicity and pollution, turning a harmful practice into a beneficial one
3Manufacturing precision
If vinyl polymers are used for leather treatment, then grain appearance and dyeing properties are improved, but waste water pollution increases
Solution Approach 1:
The patent changes the polymer source parameter from petrochemical vinyl polymers to natural biodegradable polymers. This substitution maintains the ability to improve grain appearance and dyeing properties while fundamentally reducing waste water pollution through biodegradability and reduced chemical oxygen demand in effluent
