Abstract

This study explores the conversion of Areca fruit peel into carbon-based materials biochar (BC) and hydrochar (HC) for use as adsorbents in synthetic dye removal from wastewater. Conversion was achieved through pyrolysis for BC and hydrothermal carbonization (HTC) for HC. X-ray diffraction (XRD) analysis confirmed carbon formation, with both HC and BC showing an amorphous characteristics. FTIR analysis identified hydroxyl, carboxyl, acid, and ester functional groups in BC, HC and Areca fruit peel materials that are essential for adsorption. BET surface area measurements showed 82.584 m2/g for BC and 77.618 m2/g for HC. Adsorption experiments demonstrated CR removal capacities of 40.515 mg/g for HC and 40.616 mg/g for BC, significantly surpassing the 23.168 mg/g capacity of untreated Areca fruit peel. Over three regeneration cycles, both BC and HC retained structural integrity, highlighting their potential as reusable adsorbents for dye removal. These results suggest that Areca fruit peel-derived BC and HC are promising, sustainable adsorbents for wastewater treatment, particularly in mitigating environmental impacts from industrial dyes.

Abstract

Hospital wastewater contains a high concentration of ammonia that exceed the predetermined quality standards and can cause pollution to the environment. Therefore, the treatment of hospital wastewater is required prior to being released to the environment. Effective ammonia removal process has been developed by using a combination of sponge filtration pretreatment, followed by adsorption using activated carbon from waste of tea leaves, and nanofiltration using ceramic membrane as the final process. Experiment results show the highest effectiveness of ammonia removal of 70% by using filtration only. Effectiveness is increases up to 95% by a combination of filtration and adsorption. A maximum effectiveness of 100% is achieved when using a combination of filtration, adsorption, and nanofiltration. This combination produces an optimal condition for the ammonia removal by using 3 L/min flowrate, adsorbent mass 140 g, and operating time 15 minutes at which the ammonia concentration is 0.08 mg/L. This concentration is below the standard of allowable ammonia concentration of 0.1 mg/L.

Abstract

The contamination of wastewater with synthetic dyes, particularly anionic dyes, poses a significant environmental challenge due to their persistence and difficulty in removal. Traditional adsorbents are often expensive or inefficient, driving the need for sustainable, eco-friendly alternatives. In response to this problem, this study explores the use of Eucheuma cottonii, a fast-growing and widely available macroalgae, as a raw material for producing hydrochar through hydrothermal carbonization (HTC). The goal is to develop a renewable and effective adsorbent capable of selectively removing anionic dyes from contaminated water. Hydrochar was synthesized at two different HTC temperatures, 150°C and 250°C, and its surface properties were characterized using FT-IR and BET analyses. Adsorption experiments were conducted on four anionic dyes-Congo Red (CR), Direct Yellow (DY), Methyl Orange (MO), and Direct Green (DG)-under varying pH, contact time, dye concentration, and temperature conditions. The hydrochar produced at 250°C (HC-250) demonstrated the highest surface area and pore volume, leading to superior adsorption performance, particularly for DY. Kinetic studies revealed a chemisorption-driven mechanism, while thermodynamic analysis confirmed the adsorption process to be spontaneous and endothermic, with both chemisorption and physisorption contributing to dye removal. The adsorption behavior followed the Langmuir isotherm model, indicating monolayer adsorption, with minimal interaction between adsorbed molecules. Regeneration tests confirmed that Eucheuma cottonii hydrochar could be reused over multiple cycles with minimal efficiency loss. Future work could optimize the HTC process by adjusting pressure, heating rates, and pre-treatment methods to improve adsorption properties. Incorporating nanomaterials or metal oxides could enhance adsorption for a wider range of pollutants, while machine learning could predict adsorption behavior under different conditions. Additionally, exploring the hydrochar’s use in energy storage or as a catalyst offers promising applications. Life-cycle assessments (LCAs) and techno-economic analyses (TEAs) will be vital for assessing scalability and environmental impact, positioning Eucheuma cottonii hydrochar as a sustainable, multifunctional material for industrial applications.

Abstract

This paper examines waste management’s impact on environmental sustainability in Afghanistan against the backdrop of global waste management challenges. Globally, unsustainable waste management practices contribute significantly to environmental degradation, with 1.3 billion tons of food wasted annually-one-third of global production exacerbating hunger for one in seven people. Global waste production has reached 2.01 billion tons annually, with construction contributing 35%. Packaging and paper waste account for 40-65% of waste treatment costs in Europe, and tourism adds 35 million tons of solid waste annually. Plastic waste production has risen to 300 million tons per year, threatening marine life with projections of sea pollution surpassing fish populations by 2050. In Afghanistan, financial and technical constraints lead to significant food loss and improper waste disposal, creating unsanitary environments and health hazards. Household waste mismanagement ranges from 20% to 80%, with Kabul generating 3,300 tons of waste per day by 2025, 70% of which is organic. Data from 127 respondents reveal a positive correlation (0.265) between waste management and sustainability, accounting for 26.5% of the variation, with a 0.249 coefficient confirmed at the 1% significance level.

Abstract

Water pollution is a pressing environmental issue that adversely affects aquatic ecosystems and the usability of water resources. The Batang Masumai River, located in Merangin Regency, Jambi Province, is an essential water source for local communities but faces escalating pollution challenges due to industrial, agricultural, and residential activities. This study analyzes the pollution levels of the Batang Masumai River by assessing seven key parameters: temperature, pH, Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), and Chemical Oxygen Demand (COD). A quantitative observational approach was employed, utilizing secondary data collected from 2021 to 2024. The results were evaluated against Class II water quality standards as stipulated in Government Regulation Number 22 of 2021. The findings indicate that while parameters such as temperature and pH generally adhered to acceptable standards, others, notably TSS, BOD, and COD, frequently exceeded the regulatory limits, particularly in 2021. This suggests substantial pollution stemming from untreated wastewater and soil erosion. Although improvements were observed in subsequent years, several parameters remained problematic, posing ongoing risks to aquatic ecosystems and water resource sustainability. These findings underscore the urgent need for enhanced wastewater treatment systems, stricter enforcement of environmental regulations, and the adoption of sustainable watershed management practices to restore and safeguard the ecological health of the river.
