AI Article Synopsis

  • Anaerobic digestion is an eco-friendly process that converts waste into energy, and this study specifically looks at khat and cow dung as potential feedstocks.
  • The experiment involved running batch anaerobic reactors for 27 days to measure bio-methane production, revealing that mixtures with more khat produced the highest methane yields.
  • The findings suggest that combining khat waste with cow dung enhances biomethane production through a synergistic effect, making it an effective waste-to-energy solution.

Article Abstract

Anaerobic digestion technology is one of the most paramount eco-friendly wastes to energy conversion processes. This study was conducted to characterize the physicochemical properties of khat and Cow dung along with examining the bio-methane production potential and substrate conversion rate of feedstock through seven triplicate proportions of laboratory scale batch anaerobic reactors for a 27 days digestion period under mesophilic conditions. The maximum and minimum bio-methane yield of 283.52 ± 7.17 CH mL/g VS and 142.83 ± 3.56 CH mL/g VS were generated from the digester, with the higher proportion of Khat waste in the T-5 (2:1) and the sole substrate anaerobic digestion of Cow dung in T-7 (0:1) respectively. The conversion rates of cellulose and hemicellulose components from Khat waste were 44.4 and 47.2 %, respectively. The result demonstrates that the anaerobic co-digestion of khat waste and cow dung plays a critical role in enhanced biomethane production due to effective synergism.

Article Synopsis
  • - This study analyzes the physical properties and pyrolytic behavior of Khat waste as a biofuel, demonstrating its potential to reduce waste and CO2 emissions, particularly in rural developing areas like Ethiopia.
  • - Key findings reveal that Khat waste has a density of 0.9688 g/cm³ and distinctive thermal behavior, with specific temperature points for moisture loss and decomposition of hemicellulose and cellulose identified through TGA and DTGA.
  • - Simulation with Aspen Plus shows that adjusting heating rates during pyrolysis influences the composition of the resulting biofuel, suggesting that optimized conditions can enhance Khat waste's efficiency as a renewable energy source.

Adsorptive removal of cadmium (II) from wastewater using activated carbon synthesized from stem of Khat ().

Heliyon

November 2024

Environmental and Occupational Health and Safety Department, Institute of Public Health, College of Medicine and Health Sciences, University of Gondar, Gondar, Ethiopia.

Introduction: Cadmium is among the most hazardous heavy metals, posing the greatest risk to human beings and the environment. Adsorption with activated carbon prepared from agricultural waste is the most effective way to remove cadmium (II) from wastewater. In this study, activated carbon prepared from the stem of Khat ( plant was used for the removal of cadmium (II) from wastewater.

Article Synopsis
  • The study investigates the potential of using waste from 'khat' plant (Catha edulis) in Hawassa, Ethiopia, to create fuel briquettes.
  • Charcoal fines from khat branches and leaves were combined with clay and molded into briquettes, producing the Carbonized Branch Briquette Charcoal (CBBC), which showed high calorific values and desirable performance.
  • The successful processing of khat waste into CBBC could replace 480 tons of charcoal annually and significantly lower carbon dioxide emissions by about 1,020 tons, while the Carbonized Leaves Briquette Charcoal (CLBC) needs further research due to unsatisfactory results.

Introduction: Municipal solid waste collectors are at risk of experiencing work-related health problems due to the waste they handle and the physical effort they put in. Work-related injuries among domestic waste collectors have been the subject of scant research in developing nations. Therefore, it is necessary to describe work-related injuries in these subpopulation groups.
