From Awareness-to-Action: Strengthening Waste Management Practices: Insights from Hamar Jajab District

The study examined the influence of waste management methods and practices on sustainable food production and socio-economic transformation in Ojo LGA, Lagos State. It was a descriptive cross sectional survey study and three hundred and eighty-four (384) residents were selected using multi-stage sampling technique. Three research questions guided the study. A structured questionnaire titled “Waste management methods, sustainable food production and socio-economic transformation (WMMSFSPT) was developed by the researchers. The research instrument was validated and pilot tested with reliability coefficient of 0.76. The mean and standard deviation of data were analyzed using SPSS version 20. The results of the study showed that open dumping and open burning were the most common methods adopted by the residents of Ojo LGA as waste management method. The residents of Ojo LGA are aware of few sustainable waste management practices and lack adequate knowledge on the influence of improper waste management and disposal methods on sustainable food production. The residents accepted that sustainable waste management influence socio-economic transformation through promotion of healthy environment necessary for societal development through job creation, poverty reduction, increase government revenues, agricultural productivity and sustainable food security. It was therefore recommended among others that Ojo Government Area authority should educate the residents about the environmental consequences of improper waste disposal and benefits of adopting sustainable methods and practices for fostering responsible behaviour and promoting a culture of waste reduction.

The significant resource consumption and waste generation in the construction sector highlights the imperative for sustainable management of resources and waste, particularly in Sri Lanka. Over time, various techniques have emerged as potential solutions to address this challenge, with the 5S technique standing out as a widely discussed approach. This technique is focused on producing high-quality outputs with minimal wastage and high productivity, making it well-suited for sustainable resource and waste management. However, despite its potential, there is limited research exploring its application in this context within the construction domain, specifically in Sri Lanka. Therefore, this study aimed to investigate the applicability of 5S principles for sustainable resource and waste management in Sri Lankan construction projects. Initially, a comprehensive literature review was conducted on the 5S principles and the concept of sustainable resource and waste management, which led to the development of a conceptual framework for the application of 5S principles for sustainable resource and waste management. Following this, a pilot study using interviews was conducted to investigate the specific activities that could be implemented under the individual 5S principles for sustainable resource and waste management. Integrating these activities within construction projects could help mitigate the negative environmental impacts associated with resource consumption and waste generation in the industry

Life Cycle Inventory Tools: Supporting the Development of Sustainable Solid Waste Management Systems

The rapid growth of industry, urban areas, and populations has substantially increased waste production worldwide. The inadequacy of robust waste management systems and limited resources poses significant challenges for many emerging economies, including Bangladesh, resulting in environmental contamination. Despite numerous academic studies on sustainable waste management, there is a noticeable gap in the literature concerning identifying, evaluating, and modeling critical risks associated with adopting sustainable municipal waste management systems, particularly in emerging economies like Bangladesh. This study, therefore, aims to fill this gap by identifying, categorizing, and assessing the crucial risks in implementing sustainable municipal waste management systems. Through an extensive review of existing literature and validation with expert feedback, this study employs a fuzzy synthetic evaluation method-based framework to prioritize the identified risks. The study calculates the probability of occurrence and degree of impact values to provide decision-makers with insights into the severity of different risk categories, aiding in case-by-case attention. Scores assigned on a 1 to 5 scale range from 2.59 to 4.14 for the various risk categories. Notably, “Industrial challenges related” and “Community and infrastructure requirements related” emerge as the most significant risk categories among those analyzed. This study contributes to the existing literature by employing fuzzy synthetic evaluation, a methodology rarely used to determine critical risks in municipal waste management. Furthermore, it is poised to offer valuable insights to industrialists and waste management authorities, empowering them to develop responsive strategies and contribute to the sustainable development of cities and urban communities.

Waste management in Ciburial Village, Cimenyan District, Bandung Regency still faces various challenges. Waste produced by households is usually processed individually, such as burning or landfilling it with soil. However, this method is still not effective because urban communities have limited space. Other waste management is on a paid basis, where the rubbish will be picked up by the rubbishman at each house and will end up in the final disposal site. The mass use of non-degradable and uncontrolled items, as well as deficiencies in waste processing and management, have negative implications for health and the environment. Efficient and environmentally friendly waste management is an urgent problem, and we are making every effort to bring this problem to light. Efficient and environmentally friendly waste management is an urgent need, and we are making every effort to bring attention to this problem. We want to spread our efforts and bring attention to the need for sustainable waste management by visiting every community in RT 1, RT 2, and RT 3. This qualitative descriptive research aims to detect, characterize, and explain PSAT in Ciburial Village. , Cimenyan District, Bandung Regency. Environmentally conscious volunteers and authorities from the Ciburial Community Group, Cimenyan District, Bandung Regency and other local organizations took part in this research. Apart from living in Ciburial Village, they are also active in the integrated waste management program. The findings from this research highlight the potential of integrated waste management initiatives to educate the general public about the importance of responsible waste disposal. More and more people are realizing that sustainable waste management and sorting waste for reprocessing based on type is very important. Organic waste will later be collected and reprocessed into compost, while dry waste will end up in final disposal sites.

Environmental issues have spread around the world as a result of rapidly evolving technology, industrialization, urbanization, and population expansion. Alongside this, wastes are produced as a result of rising manufacturing activities, the use of natural resources, and brisk consumption. Thus, waste management poses a great danger to both our environment and future generations and is one of the most important environmental problems of our age. Sustainable waste management should be implemented effectively in order to protect rapidly depleted natural resources within the scope of sustainable waste management, prevent the negative effects of waste on the environment and human health, and to ensure their participation as an economic input. The aim of this study is to examine the studies on sustainable waste management between the years 2010–2021 with the visual mapping method. In this context, SSCI, SCI and ESCI indexes were selected in the Web of Science database, and a search was conducted with the concept of “sustainable waste management”. There were 599 publications found with the phrase “sustainable waste management” in the title. Later, these publications were visualized and interpreted through the VOSviewer mapping method. The most frequently used keyword in the findings was “sustainable waste management”. The author with the most publications was “Yong Sik Ok”, while the most cited author was “Daniel C.W. Tsang”. It was observed that the highest number of publications among the countries was in China. China was also identified as the country with the highest number of citations. The findings of the study can be graphically visualized to obtain the most relevant information to be applied in firms. Additionally, because doing a literature review requires a lot of time, it is believed that the researchers will find the findings of this study that compiles the literature useful. For policy makers can bring new perspectives about incorporating strategies in wastes and waste management.

World class waste management is a prerequisite for sustainable urban development. This has been the overarching vision for the development of solid waste management in Malmo over the last decade. The current municipal waste management plan has a deeply holistic view, acknowledging the strong link between sustainable consumption and waste management, and giving decision makers in the municipal waste management organization a strong mandate to prioritize environmentally beneficial alternatives over less costly but more polluting ones.

PurposeThis study aims to empirically investigate the relationship between corporate social responsibility (CSR) and sustainable management of wastes and effluents (SMWE) in Lagos Megacity.Design/methodology/approachThe paper adopts a quantitative research method, specifically the use of a Web-survey technique for eliciting responses from a cross-section of companies affiliated to the Lagos Chambers of Commerce and Industry (LCCI). From a target population of 2,300 companies, a sample of 92 companies was drawn using the sample determination formula of Parten (1950). The 92 sampled companies were randomly administered Web-based questionnaires through their official emails. Finally, the 56 responses received from the participating companies (corresponding to 61 per cent response rate) were analysed electronically and the results presented using descriptive and inferential statistics.FindingsThe results show strong positive relationships between CSR and advocacy on waste and effluents (0.7), environmental impact response (0.7), environmental sustainability policy (0.6) and preventive negative impact (0.6) with P < 0.05. However, weak positive relationships exist between CSR and monitoring mechanisms (0.3) and adequacy of infrastructure for wastes and pollutants management (0.4). Overall, there is a significant positive relationship between CSR and sustainable management of solid wastes and effluents in the sampled companies in Lagos.Research limitations/implicationsThe research is limited to Lagos Megacity because it is the industrial and commercial hub of Nigeria. Besides, there are several industrial associations in Lagos, but the selected association was the LCCI with 56 sampled companies.Practical implicationsThe research supports and validates the theory of planned behaviour (TPB), which explicates that performance behaviour of organisations is influenced by the behavioural intention and behavioural control. However, behavioural intention of organisations may be carried out, abandoned or revised based on ever changing circumstances or contexts.Originality/valueThe study bridges the gap between theory and practice of environmental CSR by enriching the understanding of academics and practitioners on CSR and environmental sustainability relationships in Lagos Megacity.

Sustainable waste management has become a critical global concern, and Malaysia is no exception. With the country's increasing urbanization and economic growth, waste generation has risen significantly, posing environmental and social challenges. This paper explores the concept of sustainable waste management in Malaysia and proposes leveraging supply chain solutions as a pathway towards a greener future. The study examines the current waste management practices, their limitations, and the potential environmental impacts. It highlights the need for integrated and innovative approaches encompassing the entire waste management supply chain, from collection to disposal. By adopting sustainable supply chain practices, such as waste segregation, recycling, and waste-to-energy conversion, Malaysia can achieve more efficient resource utilization, reduce greenhouse gas emissions, and minimize landfill usage. Furthermore, the paper addresses the role of government policies, private sector engagement, and public awareness in fostering a successful transition towards sustainable waste management. The findings and recommendations presented in this study contribute to the ongoing efforts to develop a comprehensive and eco-friendly waste management system in Malaysia and serve as a model for other developing nations facing similar challenges.

South Africa has a variety of regulations on the provision of solid waste management services in municipalities because of the apartheid legacy. Nonetheless, discrepancies in waste management services persist despite new laws, legislative reforms and strategies. Those who live in marginalized and impoverished communities are the most susceptible and severely affected by improper waste management. This demonstrates a lack of integrated and sustainable waste management systems. This study aims to recommend a sustainable solid waste management system in Engcobo Local Municipality. Data was gathered through focus group discussions, documents, and semi structured interviews. Findings revealed that there has been improvements in the sustainable management of solid waste. The municipality is experimenting with novel approaches to deal with the problem of solid waste, particularly in remote locations where people’s trash is difficult to pick up and collect. Through the focus group discussions, it was shown that some participants still need more information on waste management, there is a need for thorough educational initiatives on sanitation management, not particularly wastewater and sanitation.

The farmers have to deal with a difficult time disposing surplus and rejected farm produce during the peak production season. Due to certain inappropriate and/or inadequate pre- and post-harvest management factors, the fruits and vegetables are spoilt. Further, a large amount of highly perishable wastes are obtained from agro-based industries through different series of processes like sorting, grading, processing, packaging, and distribution. Kitchen wastes also contributed majorly from fruits and vegetables. Increasing food waste generation, improper waste disposal, and poor waste management strategies have an adverse environmental issue, especially in developing countries. The search for feed substitutes due to decreasing fodder production and higher input for production pave ways for efficient waste disposal of fruits and vegetables by creating the perfect solution for developing feed resources. The study on the potential of fruit and vegetable wastes is gaining importance due to their rich nutrient and phytochemical contents, rendering them suitable as animal feed substitutes while providing a complete supplement of nutrients required for the normal growth and development of livestock. It also leads to lower cost of feeding, resulting in increased earnings for farmers. Thus livestock feed production using fruit and vegetable wastes is an eco-friendly, sustainable, and efficient waste management option. This review demonstrates the importance of fruit and vegetable wastes as an alternative source of phytochemicals and nutrients for livestock feeds.KeywordsLivestock feedsFruit and vegetable wastesWaste management

The sustainable management of construction waste represents a major challenge in promoting the circular economy. Construction is responsible for a significant amount of waste, and its proper management is essential to minimize environmental impact and create an efficient circular system. This article examines the challenges and opportunities associated with the sustainable management of construction waste. Challenges include the diversity and complexity of materials used in construction, as well as the need to develop adequate infrastructures for waste collection, sorting and recycling. However, there are also many opportunities in promoting the sustainable management of construction waste. The circular economy offers the opportunity to turn waste into valuable resources through recycling, reuse and reuse. To fully exploit these opportunities, collaboration between the public and private sectors is required, as well as the development of coherent policies and regulations for the management of construction waste. In conclusion, the sustainable management of construction waste represents both a challenge and an opportunity in promoting the circular economy. By adopting effective strategies and policies, implementing innovative technologies and involving all stakeholders, we can help reduce the impact of construction waste on the environment and build a more sustainable future. This paper was supported by the State Program 20.80009.0807.22 Development of the mechanism for the formation of the circular economy in the Republic of Moldova.

Large-scale informal recycling networks often emerge among developing economies in response to the challenges of modern urban waste accumulation. South Korea, despite its highly industrialized, developed economy, still maintains an extensive informal recycling sector made up of networks of local junk shops and individual waste pickers. As cities’ large data sources have become more widely available, the use of urban informatics in sustainable smart waste management has become more widespread. In this paper, we use geographic information system (GIS) analysis in order to uncover patterns within Korea’s informal recycling system, looking at the relationship between population demographics, waste levels, and urban planning with the prevalence of junk shops across Korea. We then interviewed junk shop owners, urban planning researchers, and government officials in order to better understand the factors that led to the coexistence of the country’s informal and formal systems of waste management and how junk shops have changed their operations over time in response to recent developments in cities’ urban fabrics. We conclude by giving suggestions for how the usage of urban informatics could increase the efficiency and sustainability of the country’s waste management systems, while also discussing the possible pitfalls of using such existing datasets for future policy decisions.

The growing environmental crisis, exacerbated by the increasing volume of food waste, presents a critical challenge for sustainable waste management globally. In countries like Malaysia, where food waste accounts for nearly 50% of household waste, the mismanagement of waste leads to environmental degradation, contributing significantly to greenhouse gas emissions. While many communities are aware of the environmental consequences of waste mismanagement, the translation of this knowledge into consistent, everyday action remains limited. Understanding the impact of community participation on sustainable waste management is crucial for designing effective interventions. The objective of this research is to investigate the effect of community participation on sustainable waste management practices, particularly focusing on the role of education and involvement in adopting skills such as composting and waste reduction. This study employed a mixed-methods approach, utilizing quantitative surveys and qualitative interviews. A sample of 200 participants was surveyed pre- and postintervention to assess changes in knowledge, attitudes, and practices (KAP) related to waste management. Additionally, focus group discussions with 30 participants were conducted to explore the social influences, challenges, and perceived benefits of the program. The results from the quantitative analysis revealed significant improvements in knowledge (mean score increase from 45.2 to 75.6), attitudes (from 40.3 to 80.1), and practices (from 35.8 to 70.4) following community-based educational programs. Furthermore, correlation analysis showed a strong positive relationship between participation levels and composting frequency (r = 0.65, p &lt; 0.001). The study concludes that community participation, combined with education, significantly enhances sustainable waste management outcomes, though challenges such as resource constraints must be addressed for long-term success.

In recent years, waste management issues have become a major concern in many major cities. One approach that has begun to be implemented is the concept of smart waste banks, which aims to improve efficiency in waste processing and monitoring in a sustainable manner. This system integrates technologies such as IoT sensors and artificial intelligence to support the process of sorting and recording waste automatically. With this system, people can more easily participate in more effective and sustainable waste management. One of the main challenges in waste management is the lack of public awareness in separating waste based on its type and disposing of waste in the appropriate place. Many individuals still dispose of waste carelessly, which leads to an increase in the volume of mixed waste that is difficult to reprocess. In addition, conventional systems in waste management often face obstacles in recording data and monitoring the amount of waste generated every day. This lack of an accurate recording system can lead to inefficiencies in the waste transportation and recycling process.
