Types of Step-Growth Polymers: Polyesters

Types of Step-Growth Polymers: Polyesters

The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated the need for starching and ironing clothes.
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the...

Area of Science:

Environmental Science
Chemical Engineering
Waste Management

Background:

Tanneries generate substantial solid waste (STW), with 80% of raw material becoming waste during leather production.
Improperly treated STW severely pollutes soil, water resources, and poses health risks to humans and animals.
STW consists of proteinaceous untanned and tanned materials requiring effective treatment for safe disposal.

Purpose of the Study:

To review and discuss eco-friendly strategies for recycling and reducing tannery solid waste (STW).
To explore the potential of STW valorization into renewable energy, biofuels, and commercial products.
To present perspectives on achieving a zero-waste policy in the tannery industry through green technology.

Main Methods:

Literature review of existing strategies for STW management.
Analysis of various recycling and reutilization approaches for tannery waste.
Overview of green-clean technologies for sustainable tannery operations.

Main Results:

Identified diverse applications for recycled STW, including biogas, biohydrogen, biodiesel, briquettes, construction materials, fertilizers, adsorbents, animal feed, proteins, fats, and enzymes.
Highlighted the environmental benefits of STW valorization, reducing pollution and conserving resources.
Emphasized the feasibility of implementing zero-waste policies through innovative technological solutions.

Conclusions:

Recycling and reutilization of tannery solid waste (STW) offer significant environmental and economic benefits.
Green-clean technologies are essential for developing sustainable tannery practices and achieving a zero-waste future.
Adoption of these strategies can mitigate the environmental impact of tanneries and ensure their long-term viability.
