Abstract Carbon dioxide (CO 2 ) is a major greenhouse gas produced by anthropogenic activities, such as industrial processes and energy consumption. This study focuses on CO adsorption, widely used method, specifically dynamic capture from the atmosphere using ammonia-modified granular activated carbon (OXA-GAC). The research integrates experimental investigations with mathematical modeling to optimize adsorption process. A numerical solution for mass balance equations, formulated partial differential equations (PDEs), was implemented method of lines (MOL). To simulate breakthrough profile in column, three kinetic models were employed: pseudo-first-order, pseudo-second-order, Avrami. Among these, Avrami model demonstrated best fit, exhibiting highest correlation factor data at 30 °C, 45 60 °C. Furthermore, two equilibrium isotherms, Toth Langmuir, evaluated. For low concentrations, Yoon-Nelson outperformed Thomas model, particularly °C across all C/C 0 ratios. At performance column accurately represented these ratios below 0.7. contributes advancement technologies optimizing OXA-GAC. It provides valuable insights into process optimization under varying temperature concentration conditions, supporting development more efficient sustainable systems.

Abstract Carbon neutrality by the mid-twenty-first century is a grand challenge requiring technological innovations. Biochar, traditional soil amendment which has been used for fertility improvement and contaminant remediation, revealed new vitality in this context. In review we highlight huge potential of biochar application different fields to mitigate as high 2.56 × 10 9 t CO 2 e total greenhouse gas (GHG) emissions per year, accounting 5.0% global GHG emissions. Soil applications either controlled-release fertilizer or an immobilization agent offer improved health while simultaneously suppressing CH 4 N O. Non-soil also contribute carbon unique ways.

Abstract Food security remains a pressing concern in the face of an increasing world population and environmental challenges. As climate change, biodiversity loss, water scarcity continue to impact agricultural productivity, traditional livestock farming faces limitations meeting growing global demand for meat dairy products. In this context, black soldier fly larvae (BSFL) have emerged as promising alternative sustainable food production. BSFL possess several advantages over conventional livestock, including their rapid growth, adaptability various organic waste substrates, low impact. Their bioconversion rate, ability transform into valuable products, final product optimization are key factors that enhance potential nutrient-rich protein source, fertilizer, biofuel. This review explores strategies rate improve end products derived from BSF treatment. It highlights benefits using other interventions underscores significance optimizing meet challenges sustainably. Despite prospects BSF-derived consumer acceptance regulatory hurdles remain critical aspects address realizing full market potential. The utilization source feed can contribute management, reduce pollution, issue environmentally responsible manner.
