The escalating production of waste in modern society has emerged as a pressing global concern, presenting multifaceted challenges to environmental sustainability, public health, and resource conservation. Addressing the burgeoning volume of diverse waste streams necessitates innovative and efficient waste degradation techniques. This comprehensive review aims to elucidate the recent advances in waste degradation methods, focusing on biological, chemical, and technological approaches [1].

The proliferation of human activities, rapid urbanization, industrialization, and changing consumption patterns has catalysed an unprecedented increase in waste generation. Traditional waste management practices, such as landfilling and incineration, pose significant environmental risks, including soil and water contamination, greenhouse gas emissions, and adverse health effects. The imperative to mitigate these impacts has fueled intensive research into novel waste degradation techniques that offer not only effective waste reduction but also environmental sustainability [2-4].

Biological degradation techniques harness the natural capabilities of microorganisms, enzymes, and biological processes to break down organic matter and contaminants. These methods encompass various strategies, such as composting, anaerobic digestion, and bio augmentation, demonstrating promising potential for organic waste treatment and pollutant remediation.

In parallel, chemical degradation approaches leverage chemical reactions, catalysts, and innovative processes to decompose or transform waste materials. Techniques like oxidation, hydrolysis, and pyrolysis are increasingly recognized for their efficacy in treating diverse waste categories, including plastics, pharmaceuticals, and hazardous chemicals [5,6].

Moreover, technological innovations have revolutionized waste management, introducing advanced recycling methods, plasma gasification, nanotechnology-based treatments, and AI-driven sorting systems. These technologies not only enhance waste degradation efficiency but also enable resource recovery, contributing to the shift towards a circular economy.

While these advancements hold promise for sustainable waste management, their widespread adoption necessitates a thorough evaluation of their environmental impacts and long-term sustainability. Balancing efficacy with eco-friendliness, energy consumption, emissions, and the generation of by-products are crucial considerations in determining the viability of these techniques on a broader scale.

This review consolidates recent progress in waste degradation techniques, aiming to provide a comprehensive understanding of their mechanisms, benefits, limitations, and environmental implications. By highlighting the latest innovations and emphasizing the integration of sustainable practices, this review seeks to guide future research and policy initiatives towards effective waste management solutions that prioritize environmental preservation and resource optimization [7- 10].
