The study modelled the methane generation for a landfill in a tropical climate in Brazil, adjusting the values of the parameters of Methane Generation Potential (Lo) and Decay Constant (k), using the IPCC numerical model and LandGEM and Biogas (CETESB) software. 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.
该研究利用IPCC数值模型和LandGEM and Biogas (CETESB)软件，对巴西热带气候下一个垃圾填埋场的甲烷生成进行了模拟，调整了甲烷生成势(Lo)和衰减常数(k)的参数值。采用大都会中心卫生填埋场第6单元(C6)公布的数据，对k和Lo进行了15种组合，以确定最能代表CH4生成的值范围。研究结果表明，k值在0.1至0.15年−1之间，Lo值在60至70 m³/t之间，可以很好地预测所选填埋场的CH4，误差低于30%。此外，当k = 0.15年−1和Lo = 60 m³/t时，这些区间能更好地代表CH4的生成。与2004年至2009年在C6测量的CH4相比，这一组合显示出估计误差小于6%，表明具有k和Lo的实验值对于调整模拟和校准使用的工具的重要性。

This study examined the capability of segmented trenches with various placements to remediate groundwater contaminated by small holes in lined waste impoundments such as landfills. A groundwater flow and mass transport model simulated a small contaminant source above an unconfined alluvial aquifer. After the leachate plume evolved for 1,000 days, the source was shut off and clean-up trials commenced. Decoupled trench configurations, with one segment at the downgradient edge of a plume, and the other at high concentrations within the plume, expedited cleanup while limiting downgradient travel. At some sites, relatively efficient schemes documented here may be effective clean-up alternatives for contemporary landfills.

Briquetting technology is one of the useful methods for sustainable management of Fecal sludge (FS). 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.

A study was undertaken to develop options for sustainable integrated solid waste management for a tourist city in Vitenam. 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.

The research aims to develop a new blend of clay brick using recycled glass fines and recycled plastics in masonry bricks with varying percentages at low curing temperature. 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.

To reduce the negative environmental impacts of waste glass, this research aims to incorporate mixed types of municipal waste glass in cement block mortars. 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.

Paper sludge waste is produced on a large scale by the paper industry and causes high environmental impacts. This work investigates the potential of paper sludge waste incorporation as an alternative raw material into a red wall tile formulation, replacing traditional limestone material by up to 5 wt%. Red wall tile pieces containing paper sludge waste were produced by uniaxial dry pressing and fired at 1170 °C using a fast-firing cycle. Technical properties of the fired wall tile pieces have been determined. The development of the fired microstructure was determined by scanning electron microscopy (SEM). It was found a water absorption of 17.15 to 18.31 %, a lexural strength of 15.77 to 16.17 MPa, a linear shrinkage of 2.88 to 3.22 %, and an apparent density of 1.76 to 1.81 g/cm3. Therefore, the results indicated that the paper sludge waste, in the range of up to 5 wt%, can produce red wall tiles (group-BIII in the ISO 13006). At the same time, this application helps minimize the environmental impacts caused by the paper industry.

Plastic waste management is a challenging task worldwide and researchers are exploring the feasibility of using plastic waste in the construction sector. This paper reports on the design and construction of a semi-automated machine that converts low density polyethylene plastic waste into construction materials such as blocks, tiles and partition panels. The performance of the machine during loading and manufacturing interlocking blocks is also discussed. The samples obtained had a compressive strength of 10 MPa corresponding to 20% strain, which is higher than that of the conventionally used construction materials.

The study's focus was to identify the primary causes of construction waste and the most effective methods for reducing them. 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.
