Microplastics in freshwater lakes: A case study from Southern India

Geosystems and Geoenvironment, Journal Year: 2024, Volume and Issue: 3(4), P. 100306 - 100306

Published: July 14, 2024

Microplastics (MP) are prevalent and virtually present in all environmental domains. Though microplastics reported worldwide, only limited studies have been carried out freshwater ecosystems. Therefore, this study was initiated to evaluate the presence of a lake (Vellayani Lake), located Thiruvananthapuram, Kerala, Southern India. The water quality assumes significance as it serves primary drinking source for thousands people Thiruvananthapuram. This analyzed seasonal distribution samples from three locations within Vellayani Lake under two distinct climatic conditions, identifying sampled locations. During monsoon sampling, abundance MP ranged 20 100 particles/m3, with an average 65 particles/m3 total 194 particles/m3. However, during summer, microplastic concentrations 34 67 particles/m³, 49 particles/m³ 147 particles/m³. Four varieties polymers, High-Density Polyethylene (HDPE), Low-Density (LDPE), Polypropylene (PP), Terephthalate (PET), detected. HDPE is most abundant polymer water, along PP, PET, LDPE. dominance polymers highlights rapid disintegration single-use disposable plastics. consumption has proven be harmful, their long residence time widespread make necessary develop new purification techniques specifically target plastic contaminants.

Addressing Plastic Waste Challenges in Africa: The Potential of Pyrolysis for Waste-to-Energy Conversion

Clean Technologies, Journal Year: 2025, Volume and Issue: 7(1), P. 20 - 20

Published: March 5, 2025

Plastic waste poses a significant challenge in Africa and around the world, with its volume continuing to increase at an alarming rate. In Africa, estimated 25–33% of daily is made up plastic, posing threat environment, marine life, human health. One potential solution this problem waste-to-energy recycling, such as pyrolysis, which involves conversion materials into oil, char, non-condensable gasses through thermochemical process absence oxygen. Given abundance continent’s energy challenges, pyrolysis offers sustainable solution. This review delves concept products, thermodynamics, endothermic kinetics, presenting it promising way address plastic Africa. Despite African Union’s goal recycle waste, continent faces barriers achieving target, including infrastructural, economic, social difficulties. It crucial implement strategies for managing mitigate environmental degradation promote cleaner healthier living environment.

Preparation and Study of a Waste Corrugated Cardboard Fiber‐Based Foamed Material With Good Hydrophobicity and Flame‐Retardant Properties

Journal of Applied Polymer Science, Journal Year: 2025, Volume and Issue: unknown

Published: March 31, 2025

ABSTRACT With environmental regulations becoming increasingly stringent, the application of traditional petroleum‐based foam cushioning materials is significantly constrained. Consequently, biodegradable biomass foams demonstrating exceptional performance have garnered significant scientific attention. This study innovatively employs waste corrugated cardboard as raw material to fabricate through a microwave‐assisted foaming technique, systematically investigating synergistic effects fiber silane modification and kaolin doping on performance. Characterization results revealed that optimized achieved maximum compressive stress 0.53 MPa at 50% strain, with water absorption reduced by 20.1%. Combustion tests demonstrated superior thermal stability, exhibiting 34.7% increase in limiting oxygen index compared conventional counterparts. In summary, silanization synergizes enhance char layer stability chemical bonding catalyzed carbonization, forming multi‐level flame retardant system. synergy also improves compatibility between fibers fillers while boosting material's hydrophobic properties, thereby substantially increasing its safety practicality. work presents sustainable strategy for upcycling packaging into high‐performance functional materials, offering groundbreaking insights developing next‐generation eco‐friendly solutions dual moisture resistance fire characteristics. The proposed methodology shows considerable potential industrial translation green applications.
