“…A study in Malaysia also recommended school campaigns and community programs to enhance public knowledge of household waste management. 20 Regarding knowledge, only 31.5% of students could accurately explain household waste's meaning. Just 54% knew solid waste management concepts and processes.…”

Background: Proper household waste management is crucial for environmental sustainability and public health. This study aimed to assess the awareness, knowledge, and practices of household waste management among 400 students and explore the associations with socio-demographic variables. Methods: A cross-sectional study was conducted using a structured questionnaire. The questionnaire covered aspects of awareness, knowledge, and practices related to household waste management. Socio-demographic information was also collected. Data were analyzed using descriptive statistics and chi-square tests to determine associations. Results: Among students, 67.8% were aware of household waste management, 84.3% knew waste separation, but only 26.3% and 35% were aware of waste minimization and e-waste. While 92.8% recognized the local government's role, almost half remained unconvinced. 65.3% knew about household waste, and 71% knew disposal methods. However, only 79.3% knew solid waste reuse, and 94.8% knew 'Swachh Bharat Abhiyan.' Practices varied: 92.5% segregated waste, 57.5% composted kitchen waste, and 70.8% disposed outside. A minority (15.3%) disposed of outdoors. Diverse waste collection methods included 29.8% using bins, 28.2% using tin cans, and 15.3% using plastic bags. Socio-demographics influenced awareness, knowledge, and practices. Conclusions: Comprehensive waste management education is needed, focusing on waste minimization and e-waste. Addressing teacher knowledge gaps is essential. Tailored education accounting for socio-demographic factors is crucial. Improved waste disposal infrastructure is required to reduce improper waste disposal. Continuing government initiatives can enhance awareness and responsible waste management.

“…However, such systems are limited mostly to affluent countries. MSW management in developing countries, including Brazil, is characterized by limited-service access for core urban population (excluding low-income population living in peri-urban areas), lack of institutional infrastructure, inappropriate technologies, and deficient management capabilities [6,7]. Insufficient municipal budget, inadequate service fee, and lack of awareness about the waste management among the citizens have been identified as some key barriers in MSW management [8].…”

Optimization of Municipal Waste Streams in Achieving Urban Circularity in the City of Curitiba, Brazil

et al. 2023

View full text Add to dashboard Cite

The municipal solid waste (MSW) remains a great challenge in most cities of developing countries, as the majority of the generated waste is either not collected or is dumped in open uncontrolled non-engineered landfill sites, creating significant pollution due to the leakage of landfill leachate in the surrounding environment. In developing countries, a complete transition to a zero-landfill scenario is less likely to happen in the near future due to various socio-economic challenges. Therefore, the existing landfills in developing countries need holistic waste management thinking with more efforts on waste to energy conversions. This study highlights the challenges with existing MSW management practices of Curitiba, Brazil, and suggests some holistic and sustainable landfill management techniques. This is accomplished through the (i) identification of the suitable sites for setting up transfer stations (TSs), (ii) route optimization for MSW transportation, and (iii) analysis of the life expectancy of the existing landfill with waste valorization techniques for enhancing circularity of MSW of the city. The study has identified six potential TSs, making use of various geological criteria and constraints as suggested by the United States Environmental Protection Agency using GIS-based spatial analysis, which could save fuel cost of approximately 1.5 million Brazilian Real (BRL) per year for the solid waste transportation (from the source to the landfill site). This research has also made a value addition in this specific field with the preparation of a digitized road network map of the study region. Further, the sensitivity-based scenario analysis highlights that the lifespan of the existing landfill (until 2030) might be extended to 2058 if the city achieves the targeted recycling rate of 85% compared with the current rate of 23%. The results would be useful for policy-makers to adopt the crucial MSW scenario to achieve a circular economy in the waste management of the city of Curitiba.

“…A total of 52% of China's urban waste is stored in landfills, 45% is incinerated, and only 3% is composted. Prajapati et al found that developing countries lack relevant financial resources and waste disposal technology [61]. Shamshad et al claimed that China's efficiency of resource recovery is significantly lower than those of developed countries owing to its different methods of waste treatment [57].…”

Identifying Waste Supply Chain Coordination Barriers with Fuzzy MCDM

2023

The stability and efficiency of the waste supply chain (WSC) is related to the urban environment. This study constructed a framework of barriers to coordinating the WSC based on four perspectives: the costs and benefits, mechanisms involved, behaviors of the subjects, and technologies and standards used. We used an analytic network process based on the fuzzy decision-making trial and evaluation laboratory to calculate the centrality and weight of each barrier factor, and we determined the critical barriers to coordination by combining their results. A causality diagram of the barriers was drawn, and a scheme of coordination of the WSC was designed based on a closed-loop supply chain around the critical barriers. The results show that contradictions in benefits between subjects, contradictions between economic and social benefits, excessive subsidies, the failure of the market mechanism, the lack of a mechanism for supervision, and blocked information and distrust among the subjects are the five most critical barriers to the coordination of the WSC, with excessive subsidies the root cause of the lack of coordination. The subsidy for direct waste disposal should be used to reduce the cost of the operation of the WSC, waste recycling should be improved, an information-sharing platform should be built, and the cost of recyclable waste for manufacturers should be reduced to improve the efficiency of the WSC.
