Evaluating E-Waste as a Partial Coarse Aggregate Substitute in M25 Concrete- A Sustainability Perspective

Global electronic waste generation is accelerating at 3% to 4% annually with forecasts indicating volumes near 55 million tons per year by 2025. Managing e-waste disposal grants substantial challenges due to harmful constituents and storage restrictions. This investigation assesses electronic waste capability as a coarse aggregate substitute in M25 grade concrete. Testing was conducted on …

Under the dominant linear “take-make-dispose” paradigm, industrial operations have greatly boosted economic growth while also accelerating resource depletion, waste production, and environmental degradation. As a result, Industrial Symbiosis (IS) has become a viable approach to integrating Circular Economy (CE) concepts into Eco-Industrial Parks (EIPs). In order to assess IS’s economic and environmental performance, this comprehensive review attempts to present a thorough examination of its mechanisms, typologies, advantages, disadvantages, and international case studies. Peer-reviewed research, international reports, and recorded EIP experiences were synthesized using a methodical literature review approach. With the aid of enabling technologies like Life Cycle Assessment, Material Flow Analysis, and digital platforms, the analysis looks at material, energy, water, and information exchanges. In addition to cost savings and increased competitiveness, case studies such as the Kalundborg symbiosis, Ulsan Eco-Industrial Park, and Tianjin Eco-Industrial Park show quantifiable decreases in greenhouse gas emissions, virgin material extraction, freshwater use, and landfill disposal. Despite these advantages, obstacles like lack of trust, financial risks, technological limitations, and regulatory restrictions still exist. The review emphasizes how smart industrial park models and digitization are increasingly contributing to the development of symbiotic networks. Overall, by fusing economic performance, long-term resilience, and environmental responsibility, IS offers a revolutionary route toward sustainable industrial development.

This study developed and evaluated a wet-cell oxyhydrogen (HHO) generation system integrated with a power management system (PMS) to improve the combustion performance and fuel efficiency of a small-capacity gasoline internal combustion engine (ICE). The HHO generator was fabricated using stainless steel (SS) electrodes arranged in a P–N–P–N configuration within a transparent acrylic cylindrical housing. …

Comprehensive Review of AI-Based Energy Management Systems for Renewable Microgrids

Microgrids are viewed as a distributed power generation system, made up of renewable power resources such as PV, wind, battery storage, shiftable loads, etc., to make a system more sustainable and resilient. But owing to the bi-directional intrinsic properties of renewable energy sources and their intermittent flow, and the randomness of renewable energy demand, energy …
