The experimental phase includes material characterization for ground granulated blast furnace slag (GGBS) and recycled concrete aggregates (RCA) to determine their physical characteristic and chemical composition. GGBS was used to partially replace cement at four levels of 0 %, 20 %, 40 %, and 60 % while the water to binder ratio was fixed at 0.5. The targeted mechanical strength properties of GGBS blended RAC were analysed at both room temperature (about 25 ℃) and after exposure to elevated temperatures of 200, 400, 600, and 800 ℃. Scanning electron microscope (SEM) analyses were conducted to study the degradation mechanism of GGBS blended recycled aggregate concrete at room temperature and after exposure to elevated temperatures. The resistance to deterioration of residual mechanical strength in GGBS-RAC was found to be significantly enhanced compared to recycled aggregate concrete without GGBS, and better residual strength performance of RAC was observed at 40 % GGBS content. The microstructure images revealed that micro/macro cracks formation, as well as the decomposition of hydrated products in recycled aggregate concrete at high temperatures, are the main reasons for the reduction of mechanical strength properties after exposure to elevated temperatures.</p></div>","PeriodicalId":100256,"journal":{"name":"Cleaner Waste Systems","volume":"4 ","pages":"Article 100069"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49701810","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 participants showed an acceptable knowledge and positive attitude towards waste picking related health risks. However, healthy and safe behaviors were not so common among them. The majority of respondents (33.6 %) not only showed continuing to work even with the knowledge of the existence of sharp objects and infectious waste in garbage bags. However, they were also weak to seek timely healthcare and medical check-up, as well as personal hygiene and healthy diet practices. These inappropriate garbage scavenging behaviors, evidenced by severe injuries, were most dominant among uneducated, low-income, and younger participants. Unsafe and life-threatening practices were explained by lack of awareness or sense of need, oblivion, difficulty to access washing facilities at city-wide, work-related fatigue, time saving, as well as high cost of personal protective equipment (PPE) and screening tests. Socio-demographic factors predicting garbage scavengers’ unsafe behaviors were also analyzed. Knowledge of garbage scavengers about exposure or outcomes of unsafe practices is unlikely to influence willingness to take safe and acceptable practices, leading to the idea that such practices are unavoidable. However, improving garbage scavengers’ perception about health risks through experienced colleagues and development of effective behaviors-changing interventions may hold great promise for promoting their health.</p></div>","PeriodicalId":100256,"journal":{"name":"Cleaner Waste Systems","volume":"4 ","pages":"Article 100064"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49701939","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}

Consumption of more than twice-used cooking oil as a source of fried food has carcinogenic effects on human health due to the changes in the molecular structure of the oil caused by high temperatures during the frying process. Furthermore, the disposal of used cooking oil into sewage systems drains, rivers and land results in environmental pollution. This community project provides awareness, exposure and training to 30 participants within the communities under the jurisdiction of the Shah Alam City Council to recycle the used cooking oil into soap production at their homes or business premises. The approach includes identifying communities and training locations, developing training modules with target groups, preparing teaching and demonstration workshops, interactive training, monitoring and impact studies. Soap optimizations were carried out in the lab and were simplified to suit the community’s knowledge background and at-home facilities. The quality of soap production was optimized by using a different formulation and analysing its moisture content, fragrance, pH value and physical properties of the soap. WCO was treated with corn flour powder, followed by the addition of an alkaline solution until the solution became slightly viscous. Statistical analysis results showed that 98.8% of the participant benefited from the knowledge transfer program, increased their awareness and received positive impacts that were measured through focus group discussions using pre- and post-questionnaires. This community service has not only raised awareness of the importance of recycling used cooking oil, but also the potential to generate new income through the business of making soap from used cooking oil, thereby improving the economy of the Selangor state community.</p></div>","PeriodicalId":100256,"journal":{"name":"Cleaner Waste Systems","volume":"4 ","pages":"Article 100084"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49701724","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}

Accurate prediction of waste aids in waste budgetary planning with optimized waste management techniques. The research found the total MW collected during the wet and dry seasons from six major markets in Kumasi, the second-most populated city in Ghana. The markets are Central, Bantama, Ayigya, Suame, Tafo and Moro. The trends over a 132-monthly period were also studied. The study utilizes Panel-Corrected Standard Errors (PSCEs) to determine the significant relationship between waste quantities and four explanatory variables: market population estimate; MPE, the distance between communal container and landfill; DIST, waste container lifting frequency; CLF and a number of communal waste containers; NOC. Time Series ARIMA model forecasts waste quantities collected in the Kumasi markets. Findings indicated an unanticipated gradual fall in annual MW quantities, from 2014 to 2018, with increasing years and attributed this to raised awareness on waste reuse and recovery practices among traders and communal dumpsite attendants, indiscriminate waste dumping by proliferated auto-rickshaw operators, and improper record keeping at the landfill. A significant relationship (R² = 59 %) between waste quantities and MPE, CLF, and DIST variables is noted from the PCSEs model. The article further demonstrated that ARIMA (4,1,3) for HDM and ARIMA (3,1,3) for LDM were robust forecasting models for MW quantities collected in Kumasi.

Waste tracking is made possible through the development of an open source LoRa-based wireless sensor network, enhanced with gateways and complemented by a cloud platform for the geolocation and visualization of bottle positions and routes. The project’s LoRa IoT sensor and antenna are seamlessly embedded in the specially designed TRACKPLAST bottle, which being identical and almost as light as the actual waste, can replicate close-to-true movement patterns when disposed in the environment. The pilot implementation of the proposed technology took place in the Greek island of Syros, where sixty-nine smart bottles were disposed freely in the environment between April 4 and May 5, 2022. The TRACKPLAST cloud platform was able to locate, track and visualize on a map, the signals of the smart bottles throughout their entire battery lifecycle and until June 24, 2022, when the last device stopped emitting its signal.

CLA was characterized through X-ray fluorescence analysis to ascertain its chemical composition. PC was substituted with 0 (control), 5, 10, 15, 20 and 25% CLA to produce six concrete batches of targeted design strength for grade 20 concrete. Fresh concrete was tested for slump and compacting factor to determine its workability. Furthermore, hardened concrete properties (density, compressive, split tensile and flexural strengths and water absorption) were investigated. The results revealed that CLA meets the requirements for application as supplementary cementitious material based on its chemical compositions. The workability and density declined with increase in CLA addition. The compressive, split tensile and flexural strengths of concrete containing CLA gradually decreased as the CLA contents with the exception of concrete with 5% CLA which showed higher strengths than the control at 90 days. The water absorption increased with increase in CLA addition but concrete with up to 5% CLA is within the permissible limit specified for good concrete. Furthermore, the proposed models from the experimental results were found to accurately predict the properties of CLA concrete when compared with the empirical models from selected codes.

A structured questionnaire was formulated and administered to a random sample of students and staff at the University of Johannesburg campuses via online Google form survey and paper-based survey. A total number of respondents who took part in the survey were 2591 where the online Google form generated 956 responses and the paper-based gave 1635 responses.

Exploratory data analysis, and Chi-squared tests for dependency were used to analyse data at α_0.05 and the development of a Logistic regression model was carried out. The qualitative data associated to the <em>collection status of bins</em> and a student’s <em>study mode</em> of the respondents showed a significant dependent relationship, and their <em>willingness to support</em> recycling where the p-values were less than 0.05. The statistical analysis of the quantitative data produced enough statistical evidence of relationships between the data, and in addition, the variables obtained from the survey and the analysis allowed for the development of a logistic model prediction for the assessment of behavioural attitudinal patterns.
