    Circular economy, life cycle assessment, and sustainability of waste derived catalysts
    (Elsevier, 2026) Shom Prakash Kushwaha, Syed Misbahul Hasan, Kuldeep Singh, Arun Kumar, Poonam Kushwaha, Abdul Hafeez, Manisha Pandey, Munendra Mohan Varshney, Hemendra Mishra, Pushpendra Soni
    With the advent of artificial intelligence and machine learning technologies, the integration of emerging AI-assisted design methodologies offers a transformative pathway to optimize catalyst performance and accelerate innovation. With these advancements waste-derived catalysts have potential to drive the transition towards a zero-waste economy and foster sustainable industrial, agricultural and waste disposal practices. Waste-derived catalysts have emerged as an important tool in addressing the environmental, economic, and social challenges associated with conventional chemical processes. These catalysts can be sourced from agricultural dumps, municipal waste, and industrial runoffs and derived as catalysts using advanced thermochemical and hydrothermal techniques. Waste-derived catalysts offer a great example of a system which follows the principles of the circular economy which helps to convert discarded materials into high-value, functional catalysts. Waste-derived catalysts have demonstrated enhanced surface properties and reactivity. The catalysts can chemically be classified as carbon-based, transition metal-based, calcium-based catalysts based on the final chemical composition of the catalyst. Comprehensive life cycle assessments of these waste-derived catalysts have shown to substantially reduce greenhouse gas emissions, energy consumption, and waste generation and thus help in mitigating environmental impacts while bolstering economic efficiencies.

    E-Waste Management System: An Approach and Assessment
    (MJS Publication, 2025) Uzma, Aqeel Ahmad Khan
    Electronic waste (e-waste) has emerged as one of the fastest-growing waste streams worldwide, primarily driven by rapid technological advancements, shortened product lifecycles, and consumer demand for modern electronics. This study aims to explore the current approaches and assess the effectiveness of e-waste management systems, with a focus on sustainable handling, disposal, and recycling practices. The research delves into the classification of e-waste, its environmental and health impacts, and the legal frameworks governing its management in both global and Indian contexts. Emphasis is placed on the roles of stakeholders, including producers, consumers, recyclers, and regulatory authorities, in the e-waste value chain. Through analysis of existing collection mechanisms, extended producer responsibility (EPR), and informal sector dynamics, the study identifies gaps in implementation and suggests strategic interventions to improve efficiency. The paper also highlights successful models from developed countries that can be adapted in developing nations to mitigate the growing crisis. Ultimately, this assessment seeks to promote an integrated, circular economy-based e-waste management approach that prioritizes environmental safety, resource recovery, and public health.
