Assessing Challenges to Solid Waste Management in Urban Local Authorities in Uganda: A Case Study of Arua Municipality

Purpose: Waste generation is associated with and comes with human activities and as such, waste management is an issue which should be shared by every individual, community, organisation or Country worldwide. Depending on climate, life style and behavioural differences, level of industrialisation, available waste management programmers and economic incentives, the problem of waste generation and its management continues to be a major environmental problem in urban centres worldwide. This Paper attempts to assess the Challenges to Solid Waste Management in Urban Local Authorities in Uganda with specific reference to Arua Municipality in North Western Uganda. A Case study design was used. Materials and Methods: A sample of 391 respondents was selected out of a Target population of 7,881 which included; Heads of Households, Business Operators, Elected leaders, Heads of Departments and Solid waste Collectors. The Methods for data collection adopted were Questionnaires, Interviews, Observation and Documentary Review. The Researcher used Regression Technique for data analysis. Findings: The study findings showed that, urban population growth had an inverse relationship with solid waste management while funding had a positive significant effect on solid waste management. The study further found out that, urban population behaviour had a negative relationship with solid waste management. Implications to Theory, Practice and Policy: From these findings the researcher concluded that lack of waste segregation; inadequate facilities and equipment, lack of legislation and bye-laws, and ineffective enforcement are among the major challenges to solid waste management in Arua Municipality. Based on the above findings, the researcher recommends the following; Solid waste segregation (separation), enforcement, legislations and bye-laws, provision of adequate solid waste management facilities and equipment and training/Capacity building programmes on solid waste management. The study findings will help policy makers in formulating sustainable solid waste management policies and designing appropriate methods of managing solid waste in urban Local Authorities. The study findings will help raise awareness on issues pertaining to solid waste management at community level. This awareness will help build initiatives to reduce the solid waste management problem in Arua Municipality. The study will further contribute to the body of knowledge on the studies already conducted on solid waste management in developing countries.

An investigation into waste handler's knowledge of management of isolation waste: A case study of Dr George Mukhari Academic Hospital, Gauteng, South Africa.

The proper management of isolation waste is of utmost importance in healthcare facilities to prevent the spread of infections and protect both healthcare workers and the general public. This study investigated waste handlers' knowledge of the management of isolation waste at Dr. George Mukhari Academic Hospital in Gauteng, South Africa. A survey was conducted to assess waste handlers' understanding of waste types, colour codes, safety precautions, and awareness of internal policies related to isolation waste management. The study found that the majority of waste handlers demonstrated a good understanding of waste types generated in the isolation unit, including sharps waste, human tissue waste, infectious waste, and general waste. They also correctly identified examples of sharp waste, such as injections, blades, glass slides, and needles. Additionally, most respondents were aware of the colour code used for representing infectious waste as "yellow" and "red." The study revealed a statistically significant association between waste handlers' age and their knowledge of isolation waste, suggesting that age may influence their understanding of waste management practices. Furthermore, experience was found to be significantly associated with waste handlers' knowledge of the health-hazardous nature of isolation waste. While the majority of waste handlers recognized the importance of wearing protective clothing and correctly marking isolation waste, some respondents were not aware of the internal policy for waste handling such as guidelines and protocols specific to the segregation, packaging, labeling, and disposal of waste generated within the isolation units. These findings highlight the importance of continuous training, targeted education, and policy dissemination to ensure effective waste management and adherence to safety protocols among waste handlers.

Review of Municipal Organic Waste Management in Uttar Pradesh State, India

Organic waste is the main fraction of municipal solid waste in most developing countries. Despite various efforts, municipalities often fail to properly handle generated waste due to poor source segregation, inefficient collection system, insufficient financial resources, and a lack of proper treatment and disposal facilities. In India, organic waste mainly ends up in open dumpsites. The Government of India launched the Swachh Bharat Mission and enacted legislation to improve solid waste management. This notwithstanding, the most populous state of the country, Uttar Pradesh (UP), faces serious challenges in terms of achieving the national environmental policy goals. This study attempts to assess organic management practices in UP by analyzing the existing situation. The study reviewed the legal and financial frameworks governing the waste sector, the responsibility of stakeholders, waste segregation and collection mechanisms in place, and treatment and disposal methods. The identified gaps were analyzed to provide recommendations for the local conditions. The study recommends the control of incoming materials in centralized facilities compost facilities to enhance compost quality and enhance the management of organic waste via source segregation, animal feeding, and treatment in a decentralized manner.

Assessment of Teachers’ Knowledge and Practices on Laboratory Waste Disposal

In alignment with the United Nations Sustainable Development Goals 2030 (UN SDGs 2030), which emphasise the importance of ensuring education inclusivity and quality for all, this study investigated the quality of education in the context of science teachers’ knowledge and practice related to laboratory waste disposal. Understanding the critical role that science teachers have in fostering a safe and sustainable learning environment, the research focused on the gap between the awareness and application of proper laboratory waste management techniques. Filling this gap is imperative not only for the well-being of the school community but also for the contribution to the broader goals of sustainable development outlined in the UN SDGs 2030. Consequently, this study assessed teachers’ knowledge and practice in handling laboratory waste disposal. As a qualitative research, this study used a phenomenological design with semi-structured interviews using open-ended questions to gather data from 20 public science teachers from Santa Rosa City and Cabuyao City in Laguna Province as respondents. Regarding teachers’ knowledge, three themes emerged, namely: (1) recycling techniques, (2) waste segregation and disposal, as well as (3) treatment of laboratory waste. However, the majority of science teachers admit that they have limited knowledge of how laboratory waste should be disposed of. They tended to apply basic knowledge of waste management that they already knew, despite being aware that laboratory waste should be treated differently from solid waste generated by our offices at schools. Teacher’s practice on laboratory waste disposal involved three steps, including identification, segregation of laboratory waste, and laboratory waste management disposal. Unfortunately, all were found to be inadequate to maintain proper laboratory waste disposal at schools. Hence, this study highlights the need to enhance awareness and facilitate training on laboratory waste disposal among teachers in public schools. Specific training and education on laboratory waste management, treatment, and disposal are essential for teachers in public schools who work in laboratory settings. Regular monitoring and evaluations of teachers’ laboratory waste disposal practices should also be implemented to ensure that they adhere to the proper procedures

The findings and recommendations provides inputs to for a sustainable service delivery and promoting responsible business practices in the airline industry.

Waste Classification System using Smart Sensors

An innovative approach to revolutionize waste management through the integration of advanced sensor technology and intelligent algorithms is proposed. Effective waste segregation is crucial in addressing the current needs. The main objective is to develop an efficient waste segregation system using various sensors to segregate degradable, non-recyclable, bio-medical waste, and organic-waste. A MCU unit with various types of sensors is used for segregation. A DC motor with conveyor belt is used to transfer wastes to respective bins, while an I2C connector with an LCD display is used to indicate the types of waste and whether the bin is filled or not. This research holds the potential to significantly mitigate environmental degradation and contribute to building a cleaner and more sustainable future. Based on the system’s performance, it can be extended to automated smart city waste management, and the skimming of crude-oil from ocean water.

An Overview of Solid Waste Management Practices in Pune, Maharashtra, India

The growing population and rapid urbanization are significant challenges for Indian cities. Pune City generates nearly 2,258 tonnes of waste per day. Pune’s informal waste sector has demonstrated remarkable efficiency, cost-effectiveness, and self-sustainability. Moreover, it contributes to favorable economic and social outcomes for the city. With the support of the self-help group SWaCH Seva Sahakari Sanstha Maryadit, Pune, the municipal solid waste management model has successfully achieved a remarkable 95 percent segregation rate. Implementing the Pune municipal solid waste management model showcases the active and efficient engagement of informal waste workers in the collection and resource utilization process. This underscores the possibility of favorable economic, social, and environmental results stemming from collaborations between municipalities and waste pickers. This paper looks at the role of SWaCH in line with Pune Municipal Corporation towards the present waste management system. Primarily reliant on labor, this model accomplishes recycling tasks at a notably lower cost compared to conventional mechanized and centralized waste management approaches. It can also accomplish high recycling levels and relatively considerable plastic waste segregation. Promoting the retrieval of valuable materials, especially plastics, for local and global recycling enterprises actively contributes to the advancement of a circular urban waste management approach. The objective of this research is to explore and provide a realistic understanding of Pune’s current status of waste generation, collection, transportation, and disposal. Apart from the SwaCH-PMC model, the paper also focuses on plastic waste recycling, the Red Dot Campaign towards sanitary waste, and household e-waste management in Pune.

Toward Environmentally sustainable surgery: Waste recycling in general surgery operating room. Preliminary cognitive audit.

It is common practice to classify waste from the operating theater as "clinical". The development of sustainable policies could have a significant impact. In the first phase, our study aims to measure general surgery waste and to assess the potential financial and carbon savings of appropriate recycling. Based on this information, we will plan for a second phase in which educational interventions will be put in place to promote waste segregation in surgical environments. We conducted a preliminary cognitive audit of the most common general surgery procedures to examine the types and quantity of waste produced. We calculated the economic and environmental impacts of disposing of waste treated as clinical or general, and we measured how much of it could actually be recycled. Then, we attempted a projection of the savings we could expect if recycling policies were implemented. We found that more than 30% of total waste was actually recyclable. Considering a projection based on annual procedures performed in our hospital, we estimated that for each kind of surgical procedure, we could expect a reduction of the carbon footprint by approximately 6%, and an average 3% reduction in costs every year, only by improving waste segregation in the general surgery operating rooms. There could be a great potential for reducing environmental and economic footprint of the operating rooms by promoting waste recycling protocols. Surgeons are in a unique position to implement for these protocols. Interventions should be codesigned with theater staff to create a "green culture".

Sustainable practices in hospital and operating theaters.

This review aims to provide an update on the results of studies published in the last two years involving the development of sustainable practices in hospital and operating theaters (OT). Recently, many studies evaluated various initiatives to better understand the environmental impact of the OT but also to minimize its environmental impact. Many trials evidenced the positive impact of the instrument's reuse using an appropriate reprocessing procedure. Better waste segregation is associated with a reduction of produced waste and contributes to a significant reduction in CO 2 equivalent emissions. Regarding anaesthetic gas, Desflurane is known to have the worst environmental impact and the majority of the study evidenced that its reduction permits to drastically reduce greenhouse gas emission of the OT. Greening the OT necessitates climate-smart actions such as waste reduction, the improvement of reusable instruments, recycling of our waste and better anaesthetic gas management. Within the last two years, many efforts have been made to reduce and better segregate waste produced in the OT and also to better understand the environmental impact of disposable and reusable devices.

Investigating the barriers and mitigation strategies for biogas adoption in a developing economy: A multi-stakeholder networks perspective

Biogas production is one of the sustainable solutions for tackling organic waste and addressing serious environmental issues. In developing nations, however, stakeholders such as farmers, biogas plant owners, project developers, and investors continue to face diverse challenges in biogas production. Research on potential mitigation strategies to address the complex challenges in biogas adoption in the developing countries context is also scarce. Accordingly, we adopted a multi-stakeholder networks perspective to investigate the barriers and potential strategies for biogas adoption in Pakistan. To this end, we conducted twelve semi-structured interviews with energy consultants and environmental experts working in the biogas industry. Building on the multi-stakeholder networks perspective, the findings contribute to the existing literature by critically analyzing diverse barriers such as the interference of farmer unions, fear of project failure, mindset issues of stakeholders, dependence on a few feedstock suppliers, and lack of policy safeguards for investors. Further, the findings provide in-depth insights into mitigation strategies such as engagement with local communities, proactive biogas policies and best practices in developed and developing economies, cost-benefit analysis of biogas production, close monitoring of the upstream supply chain activities in the biogas industry, incentivizing the segregation of municipal solid waste, and collaboration between industry and academia, which are lacking in the current literature. We argue that rich insights from the present study could facilitate practitioners, stakeholders, and policymakers in advancing sustainable biogas policies and regulatory frameworks, promoting alternative feedstock options, improving stakeholder collaboration, initiating biogas awareness programs, and effectively managing biogas supply chain operations.

MEDICAL WASTE DETECTION AND SEGREGATION USING ROBOTIC ARM

In the present world, the amount of waste material in hospitals and other commercial places is increasing. A large number of laborer’s should be allotted for waste material segregation and collection. A huge amount of money needs to be spent on the equipment and salaries of the workers. The proper management of medical waste materials is critical for the sustainability of any modern city. Medical waste is very dangerous as it can give birth to serious diseases; therefore, It is a problem of global nature. Biomedical waste consists of human tissues, medicine, needles, masks, scraps, etc. In this project, we are proposing a robotic arm to segregate medical waste. The robotic arm identifies three objects (a medicine bottle, scissors, and knife). The segregation of medical waste materials is done by using the concepts of machine learning, image processing, and deep learning. The sorting and segregation of medical waste can be done using this arm, so physical contact with the waste materials can be avoided. And the number of workers in the hospital could be reduced. The waste materials that need to be segregated should be placed in a container at the arm’s base. A camera will be placed in front of the container. The camera will identify the components, and the information will be passed to the system. Here, we use a laptop as the brain of the robotic arm. Then the robotic arm will take the waste material which will be segregated into the respective containers. The arm will be trained in such a way that the scissors will be segregated at an angle of 30 degree right, the samples will be placed 90 degrees and the medicine bottle will be segregated at an angle of 120 degree left and knife at 180 degrees left. The position of the segregated baskets will be identified by the robotic arm by the angle measurements. The robotic arm is a hardware and software system based on image processing using machine learning and deep learning for the execution of the model we use.

Permainan Pemilahan Sampah Menggunakan Construct 3 Di SDN 184 Buahbatu

One of the places of education in Bandung, namely the 184 Buahbatu State Elementary School (SDN) needs to instill concern for waste in its students. Concern for the environment at SDN 184 Buahbatu is still lacking when viewed from waste management. For example, the results of students' work using used goods were not found. The culture that considers waste to be a useless material has not been conveyed carefully by teachers, so that all waste is still considered to be disposed of or destroyed. The culture of sorting waste has not been implemented properly due to the low understanding and motivation of every student at the school. The school has not felt the direct benefits of waste segregation. There are no restrictions such as pamphlets warning not to litter, which are also needed to remind school members. The aim of the research was to design and build using Construct 3 waste sorting game application for students at SDN 184 Buahbatu in increasing awareness of the school environment and its surroundings. The game application for sorting waste is made using the ADDIE method with the help of Scirra Construct 3. As a result, through this developed waste sorting game application, teachers can deliver material about sorting carefully. So that students are more motivated to sort waste by type in the school environment.
