Adopting published data from Cell 6 (C6) of the Metropolitan Center Sanitary Landfill, 15 combinations of k and Lo were performed to determine the ranges of values that best represented the generation of CH4. The results of the study allowed to conclude that values of k between 0.1 and 0.15 year−1, and Lo between 60 and 70 m³/t, resulted in simulations with good capacity to predict CH4 for the chosen landfill, obtaining errors lower than 30%. Furthermore, these intervals identified a better representation of CH4 generation for values of k equal to 0.15 year−1 and Lo equal to 60 m³/t. This combination showed estimation errors smaller than 6% when compared to CH4 measured at C6 between 2004 to 2009, showing the importance of having experimental values of k and Lo to adjust the simulations and calibrate the used tools.","PeriodicalId":45077,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Waste and Resource Management","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89169766","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}

This study aims to evaluate the physical and thermal properties of briquettes made of FS charcoal with different binding materials. FS charcoal was produced by pyrolysis of the dry FS at 4000C and subsequently was briquetted with rice starch and different ratio of rice husk powder (RH), corncob powder (CP), wheat powder (WP), and cow dung (CD). The ratios of FS charcoal and binding materials were chosen as 80: 20, 75:25, and 70:30 for RH, CP, and WP briquettes. For CD briquettes, the ratios were 70:30, 50:50, and 30:70. Each briquette was characterized in terms of bulk density, moisture content, compressive strength, energy content, and proximate analysis. The bulk density and the compressive strength of all briquettes were in the range of 1990–2150 kg/m0 and 172–815 KPa, respectively. The moisture contents of all briquette samples achieved 5% to 8% that met DIN 51731standards. The ash content in briquettes was comparatively higher, achieving 29–46%. The energy contents of all briquette samples were above 12.0 MJ/kg indicating sustainability for combustion. The briquettes made of FS charcoal and CD were found suitable having a lower cost (0.18–0.28 US$/kg), sufficient compressive strength (>375 KPa), and desirable energy content (>13.40 MJ/kg). The produced FS briquette can be used for cooking and heating. The FS charcoal briquettes showed a potential alternative to manage human waste for sustainable environmental protection.","PeriodicalId":45077,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Waste and Resource Management","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82827402","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 generation and characterisation of tourism waste were based on a sampling survey of Hoi An city. Problems and challenges of tourism waste management system were indicated using material flow analysis. Five scenarios were developed for the city's tourism sector based on current solid waste management practice, a consensus of stakeholders, the suitability of waste management systems and the contribution of the government. In two of the scenarios, waste reduction was 6.5 times higher and recyclables recovered was 3.3−4.2 times greater than in two of the minimalist scenarios. Furthermore, the former scenarios showed more efficiency in treatment, optimal economy and minimum greenhouse gas emissions. The study indicated the advantages and challenges of each scenario and identified an optimal model for solid waste management practice for Hoi An city's tourism industry. A framework for gradually developing a sustainable tourism waste management system was proposed, potentially applicable to any tourist city in a developing country.","PeriodicalId":45077,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Waste and Resource Management","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75863915","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}

Alkaline activated solutions used in the research was sodium hydroxide (NaOH) and sodium silicate (Na2SiO3). Various percentages of alkaline activators (5%, 10%, 15%) have been initiated, while the suitable alkaline activator was set at 20%. Brick samples were placed in an oven at a heating temperature of 50°C for 24 hours (reduce the moisture content), followed by an increasing the heating temperature to 155°C for 48 hours. The previous findings demonstrated that the moisture curing for the sample was 50°C for 48 hours, and the heating temperature raised to 155°C for 24 hours. A series of laboratory testings for the brick samples such as compressive strength, water absorption, linear shrinkage, and scanning electron microscopy (SEM) characterization for the brick were evaluated in this experiment. The curing conditions examined was 7 days and 28 days. The results from the experiment revealed that the relationship between water absorption and curing conditions satisfied the minimum requirement of masonry bricks using recycled glass fines and plastics. Highlights · The microstructural properties of the masonry brick using recycled materials as aggregates was explored. · Alkaline activated bricks showed durability and improve compressive strength. · The preparation of masonry activated bricks at low heating temperature is a challenging aspect.","PeriodicalId":45077,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Waste and Resource Management","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80519835","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 waste glass was first crushed, milled and screened with #18 and #20 meshed sieves to obtain the waste glass powder (WGP). The WGP, grouped into 3 sizes; smaller (P#20WGP; 95% finer than 125 μm) and larger than #20 mesh-sieve (T#20WGP), as well as an equal mix of both sizes (M#20WGP), was used to replace sand in 0-100% ranges. The specific strength of mortars was enhanced by increasing the WGP contents. X-ray diffraction analysis suggested that carbonation at the early age observed in the P#20WGP-mortars could accelerate strength development. The extended working time test showed that the fresh WGP-mortars had the potential for casting in the first 120 min. The hand ramming method of the mortars using different amounts of WGP did not show a significant difference in mechanical properties suggesting that WGP could replace sand at all percentages. The surface temperature change, as a function of solar irradiated time, of both mortar blocks was similar.","PeriodicalId":45077,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Waste and Resource Management","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90666843","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}

In the collaborative action research methodology, a questionnaire was used as a tool. Data from 109 participants were analysed statistically using multiple regressions and descriptive statistics (percentage, mean, and t-test). Responses were collected by various stakeholders from the construction industry having different expertise, and work experience and spread across pan India. The primary causes of construction waste have been identified during material ordering, transit damage, negligent frame of mind of the working team, wrong work methodologies and improper work planning. Preparation of an appropriate waste management plan at the start and periodic review of same by senior management, use of building certification methods, correct handing and return of leftover material from the site, the trained workforce at the site and proper work methodologies are seen as being the most effective waste reduction techniques. Multiple regressions revealed that respondent work roles, experience, and type of project were substantial positive factors that influence reducing waste management at the project site. However, both the causes and solutions of construction waste were found to be human-related. Awareness of these factors must be imparted to stakeholders, which can motivate and inspire effective waste management in the construction industry.","PeriodicalId":45077,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Waste and Resource Management","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78910501","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}
