Waste to wealth: Polyhydroxyalkanoates (PHA) production from food waste for a sustainable packaging paradigm.

The growing demand for sustainable food packaging and the increasing concerns regarding environmental pollution have driven interest in biodegradable materials. This paper presents an in-depth review of the production of Polyhydroxyalkanoates (PHA), a biodegradable polymer, from food waste. PHA-based bioplastics, particularly when derived from low-cost carbon sources such as volatile fatty acids (VFAs) and waste oils, offer a promising solution for reducing plastic waste and enhancing food packaging sustainability.

A critical review and bibliometric analysis of methylene blue adsorption using leaves.

The rapid development of the industrial world causes wastewater containing dyes to continue to increase. Even in recent years, the food, textile, cosmetic, plastic, and printing industries have developed the use of dyes. Methylene blue (MB) is one of the cationic dyes widely used in dyeing silk, wood, and cotton because of its absorbency and good fastness to materials.

A comprehensive review of recent advances in the applications and biosynthesis of oxalic acid from bio-derived substrates.

Organic acids are important compounds with numerous applications in different industries. This work presents a comprehensive review of the biological synthesis of oxalic acid, an important organic acid with many industrial applications. Due to its important applications in pharmaceuticals, textiles, metal recovery, and chemical and metallurgical industries, the global demand for oxalic acid has increased.

Data-driven intelligent modeling, optimization, and global sensitivity analysis of a xanthan gum biosynthesis process.

In this study, the focus was to produce xanthan gum from pineapple waste using . Six machine learning models were employed to optimize fermentation time and key metabolic stimulants (KHPO and NHNO). The production of xanthan gum was optimized using two evolutionary optimization algorithms, particle swarm optimization, and genetic algorithm while the importance of input features was ranked using global sensitivity analysis.

Trends on adsorption of lead (Pb) using water hyacinth: Bibliometric evaluation of Scopus database.

Heavy metals (Cd, Ni, Zn, Cu, Cr, and Pb) are widely recognized as being hazardous to human health and environmentally deleterious. Therefore water hyacinth is used as a greener adsorption material. This study is a bibliometric analysis of research developments on the adsorption of lead (Pb) using water hyacinth (1995-2023).
