Leaf litter waste and floral waste biomass present in the surrounding serve as potential materials in bio-briquettes formulation. Leaf litter wastes (Almond leaves, Ashoka leaves,\u0000 Cluster fig leaves), and floral wastes such as (Marigold, Tuberose, and Rose) was used for the study. The waste was microbially treated usingLactobacillus plantarum ATCC 8014 and Lactobacillus brevis ATCC 14869 for rapid decomposition of wastes. The briquettes were formulated using\u0000 wet briquetting, manual pressure, and cylindrical mould methods. Paper pulp along with wheat bran at a 35:5 ratio was used as an artificial binding agent. The preliminary analysis includes the contents of moisture, volatile matter, ash, fixed carbon, etc. Bio briquettes were ultimately analyzed\u0000 by FESEM, FT-IR, TGA, Density, and Calorific values. Comparisons were done using untreated lignocellulosic biomass-based briquettes and commercially available briquettes. Briquettes made from waste that has undergone microbial processing have a calorific value of 5968.20w kJ/Kg, a density\u0000 of 0.26 kg/cm3, 8.4% moisture content, 10% volatile matter content, 13.65% ash content, 67.95% fixed carbon content, a maximum burning time of 17 minutes, and a minimum ignition time of 3 minutes. While the briquettes made from untreated waste have calorific value of 4205.10 kJ/Kg, density\u0000 of 0.20 kg/cm3, 10.8% moisture content, 15% volatile matter content, 15.11% ash content, 59.05% fixed carbon content. This comparative study shows microbially treated bio briquettes can offer good agriculture waste management and new fuel opportunities.","PeriodicalId":35783,"journal":{"name":"Journal of Solid Waste Technology and Management","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47284653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The major drawbacks of the OSSs are the deposition of the Faecal Sludge (FS) underground and environmental pollution due to the\u0000 indiscriminate disposal of FS. As an overpopulated country, 40% out of 162 million people live in urban areas. However, the national planning process; the Five-Year Planning (FY 2016-20) did not put emphasis on the Faecal Sludge Management (FSM). Major policies also did not address FSM though\u0000 there are various policies relevant to promote safe sanitation. Against this backdrop, it is difficult to manage the second-generation sanitation challenge like FSM services for the enormously growing urban population. However, to achieve the target of sustainable sanitation (SDG 6.2), the\u0000 country needs much attention to address the FSM services with a huge public investment to build necessary infrastructures and initiate service delivery by involving stakeholders. This study investigated the role of public finance in addressing urban FSM services in two urban centers: Dhaka\u0000 and Faridpur. The current public financing addressed FSM service for 39% of inhabitants in Faridpur; while in Dhaka, FSM service is very negligible and Dhaka Water Supply and Sewerage Authority (DWASA) is facilitating only the emptying service by engaging the private enterprises and NGOs shows\u0000 a resource gap for FSM financing. Lack of institutional coordination, role clarity on service delivery, service provisioning, capacity, leadership, and inappropriate resource sharing among the utilities are the key challenges. The study has drawn a set of public financing mechanisms to achieve\u0000 urban FSM service.","PeriodicalId":35783,"journal":{"name":"Journal of Solid Waste Technology and Management","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42045285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of low-cost, environmentally friendly adsorbents has been researched as a means of addressing problems of water contamination and high costs for waste - water treatment\u0000 processes. Malachite green is an incredibly dangerous colour that not only damages mammalian cells but also has a key influence in the growth of liver cancers. The life cycle of aquatic creatures, plants, and people is hampered by dye released into bodies of water without sufficient treatment.\u0000 In this study, the powdered lemon leaves are utilized for removal of the aniline green dye. By using batch-style setting and design of the experiment (the Box– Behnken technique) adsorbent has been investigated & have been developed to evaluate the process's critical factors, including\u0000 agitation time, size of adsorbent, dosage of adsorbent, pH, initial concentration and temperature. The acquired values were fitted with adsorption isotherms. Malachite green dye sequestration onto Lemon Leaf Powder was chosen using kinetic models. The results of the trials showed that employing\u0000 powdered lemon leaves, malachite green could be removed to a maximum of 82.21%. Malachite green dye concentration of 50 mg/L, temp of solution 303 K, and dosage of adsorbent 20 g/L are the ideal parameters. Lemon leaf powders have a maximum sorption capacity (qmax) of 8.08 mg/g. The equilibrium\u0000 was more accurately modelled using the Freundlich isotherm. When compared to other models, the data which fits the pseudo 2nd order kinetics model is better. Previously researchers had proved several low– cost materials such as wheat bran, marina alga, wood apple shell etc In the current\u0000 work, to remove malachite green dyes the efficacy of citrus lemon leaves is thoroughly done. The operating parameters that are optimized include dye solution concentration, initial solution pH, sorbent dose, and temperature. Studies on thermodynamics have demonstrated that the adsorption process\u0000 was endothermic & spontaneous.","PeriodicalId":35783,"journal":{"name":"Journal of Solid Waste Technology and Management","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46519234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
