Increasing urban wastewater and rigorous discharge regulations pose significant challenges for wastewater treatment plants (WWTP) to meet regulatory compliance while minimizing operational costs. This study explores the application of several machine learning (ML) models specifically, Artificial Neural Networks (ANN), Gradient Boosting Machines (GBM), Random Forests (RF), eXtreme Gradient Boosting (XGBoost), and hybrid RF-GBM models in predicting important WWTP variables such as Biochemical Oxygen Demand (BOD), Tot [...]

The aim of this study was to photodegrade the Polyethersulfone (PES), Polyvinylidene fluoride (PVDF) and Polymethyl methacrylate (PMMA) microplastics using Zeolitic imidazolate framework-8/Zinc oxide/Carbon (ZIF-8/ZnO/C) nanocomposite generated under laboratory conditions. The produced nanocomposite was analysed using X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Photo Spectroscopy (XPS), Scanning Electron Microscope (SEM), Diffuse reflectance UV-vis spectra (DRS) and Electron Spin R [...]

This study addresses the critical issue of carbon dioxide (CO2) emissions, focusing on understanding the intricate interplay between four major variables Gross Domestic Product per capita (GDPC), Renewal Energy (RE), Fossil Fuel energy consumption (FF), and Patent application (PTS). This research is crucial due to the emerging negative impacts of climate change, which will create a disastrous future for human beings. It focuses on three decades from 1990 to 2020 and compares the results between the United States an [...]

Watershed health and integrity are essential to human and ecosystem health and well-being. New River watershed communities in northern Belize, Central America are vulnerable to annual ‘cultural eutrophication’ - natural eutrophication exacerbated by human activity. Human-caused pollution from agriculture, septic effluent, and industrial drainage, in combination with extended drought and the slow flow of New River, has caused more frequent and prolonged periods of eutrophication. In this qualitative study, 42 New Ri [...]

Waste production is experiencing a significant increase in correlation with the growth of the human population and industrial activities. The kind of waste that is expanding at a rapid rate is known as "e-waste," which stands for electronic waste. In the context of electronic waste, the term refers to the waste produced during the disposal of electronic devices and any other components utilized in making or operating these devices. In the same way that different types of waste occur, electronic waste pollutes the e [...]

Soil salinization is a significantconstraint affecting the productivity of agricultural land worldwide. This led to the abandoning of the production of farmcrops on colossalland. Soil salinity inversely affects seed germination and plant growth and influences the plant’s biological activities like photosynthesis, respiration, plant metabolism, enzymatic activities, hormone regulation, etc. Therefore, efforts are being made to bring the saline soil under cultivation by improving itthrough a proper drainage system to [...]

Management of municipal solid waste (MSW) is frequently not properly performed. Whenever this happens, those working in the different stages of the process, as well as residents close to the dumps, face health risks. Here, we revised the documented evidence of emissions liberated during MSW management and associated health problems to investigate if systematic and reproducible relationships can be established. Besides substances released during collection and transportation, various toxic substances, predominantly [...]

Ensuring the sustainability of hospital waste management practices has become a burning issue. Due to the growing population coinciding with rapid urbanization and industrialization, practicing sustainable methods of medical waste management is an urgent requirement. Like other developing countries, Sri Lanka also faces various difficulties when dealing with high-risk hospital waste material, spreading diseases rapidly and making the environment unclean. Thus, moving towards sustainable hospital waste management ha [...]

Visual comfort affects the quality of classrooms as well as student learning. A practice-oriented approach discovers how the gap between academic research and its application in building design can be addressed. Nevertheless, the physical characteristics design of daylighting systems, including window sizes, shapes, dimensions, and materials, are considered fundamental challenges for their practicability. In this study, the physical characteristics design of daylighting systems, including window sizes, shapes, dime [...]

Breathing clean air is crucial for maintaining good human health. The air we inhale can significantly impact our physical and mental well-being, influenced by parameters such as particulate matter and gases (e.g. carbon dioxide, carbon monoxide, and nitrogen dioxide). Building on previous research that explored the effects of particulate matter (PM) in specific environments, analyzed using biometric indicators and machine learning models; this work focuses on the effects and estimation of inhaled nitrogen dioxide ( [...]
