Environmental and Toxicological Implications of Dyes: A Mini Review
Abstract: Synthetic dyes are extensively used in industries – such as textiles, leather, paper, and food processing – due to their vibrant colors and high chemical stability. However, the large-scale release of dye-containing wastewater has become a significant environmental and health concern. Owing to their complex chemical structures, most synthetic dyes are highly resistant to biodegradation, resulting in their long-term persistence in aquatic and terrestrial ecosystems. Their accumulation in water bodies …

A Futuristics Pyrolysis Technique: Conversion of Waste Plastic Polybags Into Fuel
Abstract: Plastics are high molecular weight materials composed of repeating polymer units and can be classified based on factors like chemical composition, structure, stiffness, application types, and processing methods. A key environmental issue with plastics is their non-biodegradability, causing them to persist in the environment. Pre-consumer plastic waste includes manufacturing defects, rejected items, and excess materials produced during virgin plastic manufacturing. In India, around 15,342 tons of plastic waste are collected …
