Microbial Corrosion

Microbial Corrosion

Microbiologically Influenced Corrosion (MIC) is a significant form of material degradation caused by the metabolic activities of microorganisms. This phenomenon poses substantial challenges across various industries, including oil and gas, maritime, and water treatment sectors.MIC occurs when microorganisms, such as bacteria, archaea, and fungi, colonize metal surfaces, forming biofilms that alter the local electrochemical environment. These biofilms can lead to the production of corrosive...

Bioplastics

Bioplastics

Bioplastics derived from microbial processes present a sustainable alternative to conventional petroleum-based plastics. Among these, polyhydroxyalkanoates (PHAs), particularly polyhydroxybutyrates (PHBs), have emerged as prominent candidates due to their biodegradability and biocompatibility. These polymers are synthesized by a variety of bacteria, such as Cupriavidus necator and Pseudomonas putida, which naturally accumulate PHAs as intracellular carbon and energy reserves, especially under...

Background:

The leather industry transforms slaughterhouse byproducts into valuable leather goods.
Traditional leather processing generates significant waste and environmental pollution.
Nanomaterials present a novel approach to mitigate these environmental concerns.

Purpose of the Study:

To provide an overview of conventional leather processing.
To explore the application of nanomaterials in each stage of leather production.
To highlight the potential for a more sustainable leather manufacturing process.

Main Methods:

Comprehensive literature review of scientific articles.
Identification of key stages in leather processing amenable to nanomaterial integration.
Analysis of nanomaterial types (nano-oxides, polymers, metals) for application.

Main Results:

Six key leather processing steps identified for nanomaterial application: unhairing, tanning, retanning, dyeing, fatliquoring, and finishing.
Nanomaterials can replace conventional chemicals, reducing overall chemical usage.
Improved leather properties and enhanced processing efficiency are achievable.

Conclusions:

Nanomaterials offer a viable pathway to a more sustainable and eco-friendly leather industry.
Integrating nanomaterials can significantly reduce the environmental impact of leather production.
This approach leads to both environmental benefits and improved product quality.
