Adoption of circular practices within environmental management is gaining worldwide recognition owing to rapid resource depletion and detrimental effects of climate change. The present study therefore attempted to ascertain the linkages between circular economy (CE) and sustainable development (SD) by examining the role of renewable energy (RE) and waste management (WM) sectors in CE combined with policy setup and enabling frameworks boosting the influx of circularity principles in the Indian context. Results revealed that research dedicated towards energy recovery from waste in India lacks integration with SD. Findings also revealed that although India is extremely dedicated towards attainment of the SDGs, penetration of CE principles within administration requires considerable efforts especially since WM regulations for municipal, plastic and e-waste lack alignment with CE principles. Integration of WM and RE policies under an umbrella CE policy would provide further impetus to the attainment of circularity and SD within the Indian economy.

Agricultural waste or agro-waste, including natural fibers and particles from various crop parts, is increasingly recognized as a significant contributor to environmental issues. However, from a circular economy perspective, these materials present an opportunity to be repurposed into new, eco-friendly products. The present study, specifically focuses on understanding the effect of different factors, such as the particulate loading and the size (coir and hBN - 1 to 5 wt%; Coir Powder size (100-200 μm) of the particles on composite's corrosion rates and water absorption properties.

Sustainability and environmental protection are reshaping industries, including construction, where sustainability plays a crucial role in its influence on global resource consumption and waste management. The current study has developed a reusable cement material by photo-chemical surface modification of marble powder, achieved by reacting glycidyl methacrylate with carbonate functionality. This innovative modified marble powder boosts the reusability of construction materials, unlocking new possibilities for sustainable building practices.

Background: Biowaste accounts for about 40% of total waste. Food-industry waste is one major biowaste stream. The available technological approaches to biowaste treatment are expensive, not circular, unsustainable, and they require pre-treatments such as dehydration, extraction of inhibitors, pH correction, or the addition of other organic matrices.

Biomass, as a source of lignocellulose, can be valorized into carbon micro/nanofibers for adsorbing greenhouse gas (GHGs) emissions, especially CO. This article is derived from systematic evidence evaluation of published studies, presenting new, innovative, and systemic approaches to lignocellulose-based carbon micro/nanofiber studies. The review covers a general overview of carbon micro/nanofiber studies, mapping chronicles of the studies, carbon micro/nanofiber types for CO uptake, carbon micro/nanofibers fabrication and characterization, obtained carbonaceous material activation and performances, regulatory frameworks, and sustainability.

Azo dyes constitute 60-70% of commercially used dyes and are complex, carcinogenic, and mutagenic pollutants that negatively impact soil composition, water bodies, flora, and fauna. Conventional azo dye degradation techniques have drawbacks such as high production and maintenance costs, use of hazardous chemicals, membrane clogging, and sludge generation. Constructed Wetland-Microbial Fuel Cells (CW-MFCs) offer a promising sustainable approach for the bio-electrodegradation of azo dyes from textile wastewater.
