Recent Developments in the Application of Gallus domesticus Eggshells for the Biosorption of Dyes and Heavy Metals

Received: 29 July 2024;  Published: 28 November 2024;  doi: 10.21926/aeer.2404024

Abstract

Global efforts to develop low-cost solutions for the treatment of contaminants in wastewater continue unabated. The conversion of eggshells, a waste material, into a high-value product can be economical and environmentally sustainable. The recent developments in applying eggshells towards the biosorption of contaminants are presented. Eggshells effectively remove pollutants such as metal cations, metal anions, and reactive, basic, and direct dyes. Promising advances in modifying eggshells, elucidating the critical [...]

From Killer to Solution: Evaluating Bioremediation Strategies on Microbial Diversity in Crude Oil-Contaminated Soil over Three to Six Months in Port Harcourt, Nigeria

Received: 12 May 2024;  Published: 05 November 2024;  doi: 10.21926/aeer.2404023

Abstract

The study aimed to evaluate the efficacy of various bioremediation approaches on microbial diversity in crude oil-contaminated soil over three to six months in Port Harcourt, Nigeria. The objective was to assess the impact of different bioremediation strategies on microbial populations, particularly focusing on hydrocarbon-utilizing bacteria and fungi. Microbial populations were quantified using serial dilution and microbial count techniques. The vapor phase transfer mechanism was employed to estimate hydrocarbon-u [...]

Challenges of Applying Circular Economy in Agricultural Sustainable Development: A Case Study of Kurdistan Province, Iran

Received: 06 August 2024;  Published: 31 October 2024;  doi: 10.21926/aeer.2404022

Abstract

Current production and distribution models in agriculture primarily operate based on the 'linear economy' approach. This means that after the exploitation of natural resources and the production of the final product, a significant portion of these resources and products, now contaminated or turned into waste, exit the economic cycle. The circular economy approach in agriculture seeks to reuse waste products and depleted inputs, thereby reducing the intensity of resource exploitation and taking a step towards sustai [...]

Comparative Study on the Applicability of Solid Waste Treatment by Fixed Grate and Fluidized Bed Incinerators: A Bibliometric Review

Received: 16 May 2024;  Published: 21 October 2024;  doi: 10.21926/aeer.2404021

Abstract

Using thermal treatment in the waste management process has advantages such as reducing volume and the possibility of energy recovery. There are several incineration technologies with different characteristics and potential. Incineration, however, requires efficient environmental control to reduce associated risks, such as the emission of harmful compounds. The paper aims to compare solid waste treatment processes in grate and fluidized bed incinerators based on technical and environmental characteristics. For this [...]

Comparative Analysis of Machine Learning Models and Explainable Artificial Intelligence for Predicting Wastewater Treatment Plant Variables

Received: 30 July 2024;  Published: 17 October 2024;  doi: 10.21926/aeer.2404020

Abstract

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 [...]

Photodegradation of Polyethersulfone (PES), Polyvinylidene Fluoride (PVDF) and Polymethyl Methacrylate (PMMA) Microplastics via a Metal Organic Framework Namely ZIF-8/ZnO/C

Received: 27 August 2024;  Published: 17 October 2024;  doi: 10.21926/aeer.2404019

Abstract

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 [...]

Comparative Analysis of the Relationship between Renewable Energy Adoption, Fossil Fuel Energy Consumption, and CO2 Emission in the United States and China

Received: 11 March 2024;  Published: 26 September 2024;  doi: 10.21926/aeer.2403018

Abstract

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 [...]

Cultural Eutrophication Impacts on New River in Northern Belize: A Community Capitals Assessment

Received: 02 March 2024;  Published: 25 July 2024;  doi: 10.21926/aeer.2403017

Abstract

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 [...]

The Importance of Responsible Electronic Waste Treatment for Sustainability

Received: 02 January 2024;  Published: 01 July 2024;  doi: 10.21926/aeer.2403016

Abstract

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 [...]

Received: 14 March 2024;  Published: 12 June 2024;  doi: 10.21926/aeer.2402015

Abstract

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 [...]
