Implementation of Environmental Hygiene and Sanitation in Deli Tua Market, Deli Serdang District

The market is a public facility that involves many people and physical interactions that can be a means of spreading disease. Further research is needed because the initial observation results show non- compliance with PERMENKES RI No. 17 of 2022 in terms of the application of personal hygiene, spatial arrangement, drainage, and market buildings. The purpose of this study is to analyze the extent of the application of environmental hygiene and sanitation in the Old Deli Market. This research uses qualitative methods with descriptive type research, and data collection using direct observation, in-depth interviews, and documentation. The selection of key informants in this study used purposive sampling method. The results showed that Deli Tua Market has not met the requirements of a healthy market according to PERMENKES RI No. 17 of 2020. Waste management facilities are still smelly and scattered. Clean water facilities are not available by the market manager. Vector control facilities have never been sprayed every month. Hand washing facilities are not available and are not equipped with soap and running water. The application of personal hygiene of traders is not in accordance with the requirements such as incomplete PPE, smoking, spitting, littering in the market environment and not washing hands while the hygiene of traders meets the requirements and drainage channels also meet the requirements because the drainage channels are cemented and covered with gratings and metal and drainage channels are smooth.

Quick Assesment Study On Condition Of Marine Debris From Fisheries Activities At Tegalsari Fishing Port In Tegal City

Waste is a significant environmental issue faced by one of the largest fishing ports in Central Java, PPP Tegalsari. PPP Tegalsari has been reported to have a slum status, evidenced by the accumulation of trash at key points in the port. The purpose of this rapid assessment activity is to evaluate the waste management status and waste conditions in the Tegalsari Coastal Fishing Port area. Primary data was collected through observations, in-depth interviews using an interview guide, and surveys using questionnaires and waste calculation forms, while secondary data was gathered from government stakeholders, scientific journals, and reports from relevant agencies. The results of the Rapid Assessment conducted from June 14, 2021, to June 19, 2021, include infrastructure facilities for waste management, human resources, waste management policies, sources of waste activities, daily waste generation, potential leakage of waste into the sea, waste composition, and waste management in the area, indicating that approximately 2,240 kg/day of waste is generated at the Tegalsari Fishery Port during times of low ship activity, with the fish processing/filleting industry producing the most waste at 652.3 kg/day, while the dock area generates the least amount at 287 kg/day. The handling of plastic waste management on the fishing vessel PPP Tegalsari consists of two methods: direct disposal into the sea and return to the port. The implementation of waste management based on handling and reducing waste is still in its early stages due to the fact that several requirements have not yet been met. It can be concluded that the waste conditions and waste management at PPP Tegalsari require improvements in waste management infrastructure, capacity building, the establishment of waste management institutions, as well as regulatory improvements and the creation of a sustainable waste management system.

Analysis of Household Waste Generation and Composition in Mandalay: Urban–Rural Comparison and Implications for Optimizing Waste Management Facilities

Data on waste generation and composition are fundamental for effective waste management and can vary over time. Assessing the allocation of waste management facilities is also important to improve the entire waste management system, including land management. A survey conducted among 108 households in both urban and rural areas across six townships analyzed the waste generation and physical composition in Mandalay, highlighting the current trends relating to waste. Concurrently, data on current waste management facilities were gathered. The average waste generation is 0.84 kg/person/day, with urban areas producing 0.91 kg/person/day and rural areas 0.37 kg/person/day. The per capita waste generation rate reported in this study exceeds those in most previous studies conducted in Mandalay up to 2020, as well as the national average and that of most cities in Myanmar. Organic waste constitutes most of the physical composition, accounting for 82.3%, followed by plastic waste (10.7%), paper and cardboard (3.2%), glass (0.9%), metal (0.8%), leather and fabric (0.4%), and other waste (1.7%). Rural areas produce a higher percentage of most types of waste compared with urban areas, except for organic waste. Surprisingly, urban areas produce waste with a higher organic composition compared with rural areas. The percentage of organic waste was found to be higher than in previous studies conducted in Mandalay and other cities. Proper management of organic waste could significantly reduce the burden on waste management. In order to achieve this goal, this study proposes several viable strategies for optimizing solid waste management in Mandalay. The current location of waste management facilities reflects the efficiency of waste management and accessibility. However, there are concerns about this and improvements are necessary. These can be achieved by optimizing the placement of waste management facilities and enhancing the efficiency of the collection and transportation sector.

Anthropogenic and Natural Impacts on Surface Water Quality: The Consequences and Challenges at the Nexus of Waste Management Facilities, Industrial Zones, and Protected Areas

AbstractThe objective of this study was to evaluate the physicochemical characteristics of surface waters near an old landfill, to assess water quality using the Water Quality Index (WQI) and the Comprehensive Pollution Index (CPI), and to identify factors influencing surface water composition using multivariate statistical analysis. The analysis of temporal changes of 15 surface water parameters (pH, EC, Cl−, NH4+, SO42−, BOD5, CODCr, TOC, Zn, Cd, Pb, Cu, Cr, Hg, and PAH) was complemented by the investigation of surface water flow, ambient temperature, and precipitation. A twelve-year monitoring period was considered, focusing on monitoring sites located along a watercourse in the area of the Radiowo landfill (Poland). No significant correlations were found between precipitation and surface water quality parameters in the outflow direction. The results showed that the average WQI values ranged from 63.06 to 96.86, while the average CPI values ranged from 0.56 to 0.88, indicating good water quality or low pollution, respectively. The temperature had a greater influence on the physicochemical parameters than the precipitation, especially on the parameters of contamination by organic compound (correlations between temperature and BOD5, CODCr, and TOC of 0.40, 0.50, and 0.38, respectively). Significant correlations were observed between EC, Cl−, NH4, BOD5, CODCr, and TOC in the outflow direction of the landfill. In addition, surface water flow showed a significant moderate negative correlation with pH (r = -0.44) and a moderate positive correlation with Cu concentration (r = 0.47) downstream of the landfill. The analysis of surface water quality monitoring, coupled with the critical evaluation of global research, has made it possible to understand the variation in surface water quality and the factors that influence it. The study confirmed that given the complex nature of Municipal Solid Waste (MSW) landfills, understanding the dynamics and factors affecting water quality is essential for effective water protection and management and achieving the Sustainable Development Goals (SDGs).

Regional Framework Towards Establishing Treatment, Storage, and Disposal (TSD) Facilities for PV Waste Management in the Philippines: A Case Study of Laguna Province

Abstract. The accelerated adoption of photovoltaic (PV) systems for renewable power generation in the Philippines will yield a tremendous amount of PV waste. However, the country lacks a comprehensive framework for understanding PV module waste volume growth and optimally siting Treatment, Storage, and Disposal (TSD) facilities for PV waste management based on minimum siting factor. The study aims to develop a regional framework that utilizes a geographic information system (GIS)-based approach to find the potential sites and optimal locations of TSD facilities in Laguna, Philippines, based on the estimated PV module waste growth of solar energy systems with service contracts and minimum siting criteria under Department of Environment and Natural Resources (DENR) Administrative Order 2013-22. By 2060, the projected amount of PV module waste in Laguna province will be around 162,230 metric tons based on the waste projection results. The suitable sites cover around 19,720.5 hectares or 11.21% of the total land area of Laguna, which were determined by various siting factors that encompass social, economic, and environmental factors and obtained using binary suitability analysis and vector overlay analysis. The optimal locations of the two TSD facilities were identified using strategic positioning based on hotspot analysis, clustering algorithm, and proximity analysis. Consequently, the distance and GHG emissions of the two optimal locations were calculated. Indeed, the approach will serve as a guide for policymakers and other stakeholders in understanding PV module waste growth and strategically and optimally position TSD facilities on suitable sites for efficient and effective PV waste management.

Exploring Community Perspectives on Household Waste Management in Dili

This study explores the relationship between the knowledge, attitudes, and behavior of the community in managing household waste in the Urban Village of Lahane Oriental, Dili. This study was motivated by the growing global and local challenges of waste management, particularly in urban areas where population growth exacerbates this issue. This research employed an analytical observational design with a cross-sectional approach, using questionnaires distributed to 96 respondents selected through simple random sampling. Data were analyzed using descriptive statistics and Pearson’s correlation to assess the relationship between knowledge, attitudes, and behavior. The results showed that the majority of respondents (61.5%) had sufficient knowledge of waste management, while 62.5% demonstrated a positive attitude toward proper waste management. However, the community's waste management behavior did not fully meet the expected standards, despite generally positive attitudes and moderate knowledge. These findings indicate that, although knowledge and attitudes play an important role in influencing behavior, the lack of adequate infrastructure and institutional support remains a major obstacle to optimal waste management practices. It was concluded that further educational campaigns and improvements in waste management facilities are crucial for enhancing community engagement in sustainable waste management. The findings provide practical implications for local governments and policymakers in designing effective waste management interventions that consider both behavioral and structural factors.

Application of coniferous bark as sorbent material for per- and polyfluoroalkyl substances – A case study in Sweden

Per- and polyfluoroalkyl substances (PFAS) are anthropogenic contaminants commonly found in drainage water from waste management facilities. Within the European Union, these facilities either treat the water locally or transfer it to wastewater treatment plants to reduce harmful emissions. However, PFAS are a broad class of compounds with varying physicochemical properties, leading to different removal efficiencies for adsorbents. Activated carbon and ion exchange resins are effective but costly, and they can become saturated with other contaminants. Therefore, this study aims to explore inexpensive, abundant alternatives for reducing PFAS concentrations in the environment. In Sweden, bark is a by-product of forestry activities, primarily used as fuel in heat and power plants. This study evaluates the ability of pine and spruce bark to remove PFAS from contaminated drainage water. Initial laboratory experiments employed liquid-to-solid ratios of 10 and 20 to assess the performance of both materials. Results indicated that pine bark exhibited better removal efficiencies, particularly when a layered column with pine bark followed by spruce bark was utilized. The overall removal efficiencies for short-chain PFAS (perfluorinated carbons: PFCA C3–C6 and PFSA C4–C5) and long-chain PFAS (PFCA > C7 and PFSA > C6) were below 20%, except for perfluorooctane sulfonic acid (PFOS), which showed reductions of 40%–80%. The pH of the treated water decreased from 7 to 4 (pine bark) and 5 (spruce bark) after treatment. In a larger-scale trial, a combination of 50% pine bark and 50% spruce bark was tested, achieving similar reductions for PFOS. Although the removal efficiencies were insufficient for exclusive treatment, these materials may be useful in specific applications targeting long-chain PFAS or in conjunction with other treatment methods.

Sustainability performance assessment of sago industry supply chain using a multi-criteria adaptive fuzzy inference model

Background Sustainable supply chains are more competitive than conventional supply chains. Supply chain sustainability performance needs to be carried out to determine sustainability under current conditions and to design appropriate strategies to increase sustainability. This study aims to design a sustainability performance assessment model for the sago agro-industry supply chain and identify critical indicators for sustainability improvement. Methods The Fuzzy Inference System (FIS) evaluates sustainability on three levels: economic, social, and environmental. The Adaptive Neuro-Fuzzy Inference System (ANFIS) is then used to aggregate the overall sustainability performance. The cosine amplitude method (CAM) was used to analyze key indicators. This study assessed the sustainability performance on industrial- and small-medium-scale sago agro-industry. Results The results show that the supply chain sustainability performance on the industrial scale is 44.25, while it is 48.81 for the small-medium scale with the same status, almost sustainable. Key indicators for improving sago agro-industry supply chain sustainability performance include profit distribution among supply chain actors, institutional support for supply chains, waste utilization (reuse & recycle), and the availability of waste management facilities. The implication of this research for managers regards assessing the current status of sustainability performance and key indicators as a reference for formulating sustainability strategies and practices. Implication The sago agro-industry sustainability performance evaluation methodology uses industry-relevant metrics to assess supply chain sustainability, promoting collaboration among stakeholders and assisting in the creation of sustainable strategies. Conclusions The results of the study will enable supply chain actors to understand the key indicators for improving sustainability performance in the sago agro-industry supply chain, especially in Meranti Islands Regency, Riau Province. The proposed model can be applied to other agro-industries by adjusting the indicators used and assessing data availability and suitability for the research object.

Impact of Debris Removal Post-Wildfires on Pavement Fatigue and Rutting Lives: Case Studies of California’s Camp and Carr Fires

Between 2017 and 2018, California experienced a series of four devastating fires, including the Camp and Carr Fires, which ranked among the most destructive fires in U.S. history. During these fires, roads were critical in the evacuation, rescue operations, goods transportation, and access to critical services. Additionally, postfire, road infrastructure became crucial for removing hazardous and nonhazardous waste from fire-affected areas to major landfills and recycling facilities. Despite the significance of pavements in this process, previous studies have not quantitatively assessed the potential damage caused to pavements by the additional trucks used in debris removal operations. This research aimed to address this knowledge gap by collecting precise traffic data for the routes taken to waste management facilities, including data on the number of trips involved in debris transportation. The traffic information was then utilized to calculate changes in equivalent single axle loads and traffic index values for pavement design. Pavement structures were obtained from the available core database. Pavement simulation results showed that of the nine studied highways, only one exhibited a reduction in cracking life of about 2 years. However, Skyway, the main artery in the town of Paradise, demonstrated a significantly accelerated fatigue cracking failure by 14.3 years. A sensitivity analysis of fire intensity showed other highway sections that were structurally adequate could be affected by larger fires. The presented methodology could be used in traffic planning as part of debris management operations to avoid vulnerable pavement sections.

Review of Waste Management in Indonesian Small Islands in the Last Five Years (2018-2023)

Indonesia is a maritime country composed of 16,771 islands consisting of large islands and small islands. One of the environmental problems that occur in small islands. Waste management is a shared focus because sources of water, soil and air pollution can come from waste. Waste management on small islands is very important because small islands have a much higher vulnerability than large islands.. This article aims to identify and analyze waste management in Indonesia's Small Islands and evaluate if its implementation has utilized the technology and concepts of the Industrial Revolution 4.0. Based on the findings of a review of 14 articles published from 2018-2023, with 15 islands as research objects, it was found that most of the small islands used as research objects had not managed their waste properly. The waste is eventually dumped into the sea. The unmanaged factor of this waste can be caused by the geographical conditions on the island which are bordered by the sea, the lack of waste management facilities, the limited land area on small islands and the low awareness and participation of the community in waste management. The rest, several islands have carried out the process of storage, processing, collection and destruction quite well. The waste is turned into handicrafts (bags and souvenirs), ecobricks, garden decorations and plant fertilizers for organic waste as well as the development of innovative waste into diesel fuel. Unfortunately, the intended application based on the Industrial Revolution 4.0 has not been reflected in waste management on these small islands. This is expected to be information and input for the government and managers as a model for other small islands in an effort to manage waste generation on the island's mainland and garbage contamination in the sea.

Partisipasi Masyarakat Terkait Pengelolaan Sampah di Kelurahan Fatululi Kota Kupang

Waste is becoming a new problem, as there are fewer and fewer landfills and more and more waste is being produced. The lack of public awareness also exacerbates the waste problem. The purpose of this research is to find out the increase in community participation related to waste management and to find out what are the factors that hinder community participation related to waste management in Fatululi Village, Kupang City. This research is empirical juridical in nature, namely research whose data is obtained through direct tracing at the research location, in Fatululi Village, Kupang City. The type of approach used is the literature approach, Field Study Approach with qualitative descriptive analysis techniques. The results of this study show that community participation in waste management in Fatululi Village, Kupang City can be said to be low because people still litter and lack of community participation in community service activities. In the implementation of waste management in Fatululi Village, the Department of Cleanliness and Environment faces several obstacles, namely very low community participation, facilities in the form of minimal waste management facilities and infrastructure and there is still no local regulation governing sanctions for people who litter.

Waste Governance and Empowerment: Evidence from Ponorogo, Indonesia

This research is a case study with a qualitative descriptive approach, aiming to describe and analyze Waste Governance on community empowerment in waste management in Ponorogo Regency, Indonesia. This research designs a recommendation model, taking into account empirical conditions in the field. Data collection in this study used interviews, observation, documentation, and focus group discussions. This research involved informants from various elements in Waste Governance, including government, community, industry, academics, mass media, NGOs/Communities, and regulators. This research stems from the low community empowerment in managing community-based waste management facilities in Ponorogo Regency, Indonesia. This condition is caused by the low participation and involvement of the community in various community empowerment programs in waste management, resulting in the community's role becoming less than optimal in Waste Governance. This study illustrates the weak aspects of Waste Governance in Ponorogo Regency, Indonesia, such as: weak collaboration between the community and academics in community empowerment in waste management, failure to accommodate waste governance in business, education, and environmental interests, and not maximizing the institutionalization of the waste management agenda through the Clean Friday Movement. This research recommends strengthening aspects of Waste Governance, namely encouraging local leadership as a driving force in waste governance. This aspect relates to the role of local leadership and community leaders in mobilizing various community-based waste management facilities. The results of this research are expected to contribute to developing Waste Governance theory, as well as provide practical benefits in the practice of Waste Governance in Indonesia.

The Role of Government and Community Collaboration in the Implementation of Waste Management Policies in Palu City

Waste management is a crucial issue for the growing city of Palu. Collaboration between the government and the community is the key to effective and sustainable waste management policy implementation. This study aims to describe the collaborative role between the government and the community in the implementation of waste management policies in Palu City. The method used is descriptive, with data collection through observation, in-depth interviews with relevant parties, and analysis of waste management policy documents. The data obtained was analysed qualitatively to provide an overview of the dynamics of collaboration that occurred. The results showed that the Palu City government has played a role in formulating policies, providing waste management facilities and infrastructure, and building a supportive regulatory framework. The government also initiated waste management programmes such as waste banks and temporary disposal sites (TPS)). On the other hand, the role of the community is seen through active participation in these programmes, as well as involvement in waste reduction and recycling activities in their respective neighbourhoods. Nonetheless, challenges are still faced, including the low level of public awareness, the lack of supporting facilities, and inadequate law enforcement. This study concludes that good collaboration between the government and the community is essential in achieving more effective waste management in Palu City. Strengthening collaboration through education, improving facilities, and consistent law enforcement are needed so that waste management policies can be implemented optimally.

Practising urban agriculture positively influences household organic waste management habits: A quantitative study from Florianópolis, Brazil.

Proper household organic waste management practices are crucial to limit the negative environmental and health impacts that can result from inappropriate municipal waste treatment. The environmental impacts of organic waste have previously been described in the literature, and the main treatment strategy for managing such waste relies on technical facilities such as biodigesters. However, such technologies require significant financial investments, which could hinder their application in areas with lower economic power. Among the several available organic waste treatment strategies, composting for urban agricultural (UA) use has become increasingly popular. Although the literature suggests that UA can contribute to organic waste management by encouraging self-treatment practices, investigations into how practising UA can influence household waste management behaviours have been limited thus far. To this end, we analyse the role of practising UA along with other demographic variables, such as age, gender, education, income and housing conditions, in influencing citizens' household organic waste management behaviours. The city of Florianópolis, Brazil was selected as a case study since that municipality recently passed a new organic waste regulation law that supports the use of organic compost in UA. We surveyed 206 individuals regarding their household organic waste management habits in four behavioural areas: (i) separation, (ii) use of public services, (iii) self-treatment and (iv) reduction. The dataset comprises 102 individuals who were actively engaged in UA activities and 104 who were not involved in UA to compare habits of the two groups. The results show that UA practitioners are more likely to separate and self-treat their organic waste and use the derived compost for gardening activities. The use of public facilities for organic waste management is influenced by people's housing conditions. Respondents who lived in an apartment with no access to a garden logically had a lower willingness than did those with garden access to self-treat the organic waste produced. On the other hand, the results show that UA practitioners compost their own organic waste regardless of their housing conditions. The results show a strong, positive influence of practising UA on self-composting and thereby highlight the role of such practices in sensitizing urban residents to waste management issues and supporting local organic waste management strategies. Although the debate over the role of UA in organic waste management is still open, we reveal that highlighting this role could support a shift towards a circular approach to organic waste treatment.

Genome sequences of three plastic-debris-inhabiting fungi isolated from New Zealand waste and recycling management plants.

Cladosporium and Epicoccum are cosmopolitan fungi of the class Dothideomycetes with few cultured and genomic representatives. Here, we report draft reference genome sequences of Epicoccum sp. F181 (GenBank accession number JAJSLS01), Cladosporium sp. F165 (JAJSLR01), and F190 (JAJSLT01) isolated from recycling and waste management facilities in New Zealand.

Deep learning implementation using convolutional neural network in inorganic packaging waste sorting

Municipal solid waste is a significant issue that causes environmental contamination. One of the most prevalent wastes that is difficult to decompose is waste from inorganic packaging. Inorganic packaging waste management can be done by sorting waste as the first step before going through subsequent processing. However, waste sorting is currently still difficult to do by human power in waste management facilities, so it is necessary to design a system that can assist the waste sorting process. This research aims to develop a model that can classify inorganic packaging at waste processing sites. To develop the model, we used five pre-trained Convolutional Neural Network (CNN) architectures, namely Xception, Inception V3, ResNet-50, Resnet-50 V2, and DenseNet-201. Then, the best architecture based on some metric performances will be tuned. The result displayed that the CNN model with Densenet 201 architecture, accompanied by tuning, achieved the best performance to classify the waste. The accuracy for the validation dataset is 95.31 %, the accuracy for the testing dataset is 95.6 %, precision is 0.96, recall is 0.96, and the F1-score is 0.96. The results of those performance metrics show that the model can predict the image of inorganic packaging waste well for further application to an automated waste sorting system.

Landscape and habitat characteristics jointly drive the urban distribution of a nuisance species

Identifying environmental variables that affect the distribution of pest and/or nuisance species promotes effective management strategies by improving urban planning and the targeted application of direct interventions like population control. Australian white ibis Threskiornis moluccus are considered a nuisance species throughout Australia, having increased significantly in abundance in coastal urban landscapes following declines in their native inland habitats over the past three decades. Few management interventions thus far have successfully reduced conflicts between ibis and humans, necessitating a better understanding of conditions driving ibis distribution and abundance. We surveyed 26 ibis colonies throughout the Moreton Bay region in central eastern Australia and quantified the effects of a range of spatial (e.g. connectivity with waste management facilities, urban land and wetlands) and habitat (e.g. nesting tree species, density and size) variables on ibis and nest abundance. Ibis and their nests were most abundant at sites within 10 km of waste management facilities, and < 60 m from residential or industrial estates. Ibis were also more abundant at sites with tree canopy height < 10 m and lower tree species richness. Nests were most abundant on water bound islands with tree density > 0.5 trees/m2. Urbanisation had contrasting effects, with nest numbers increasing with higher connectivity (i.e. closer proximity) to urban land, while ibis numbers decreased (relative to waste management facilities). Multifaceted approaches are required for controlling ibis populations, including restricting access to anthropogenic food resources, managing the condition of remnant habitats, and considering population control at sites with high connectivity to foraging grounds.

Aim. To build a system of inter-territorial interaction and cooperation in the sphere of waste management.Objectives. To develop a model of interterritorial interaction and cooperation in the sphere of waste management; to offer directions and forms of interterritorial interaction and cooperation in the investigated sphere.Methods. The author used the methods of analysis and synthesis, generalization and classification, as well as modeling. Legislative acts of the Russian Federation (RF), data of official governmental sites of the RF and the Republic of Bashkortostan, scientific articles, monographs, periodicals in the field of ecological monitoring of territories, data of the public-law company “Russian Ecological Operator” (PPC “REO”), statistical collections devoted to the researched subject served as a methodological basis for model building.Results. The author of the article proposes a model of inter-territorial interaction and cooperation, which includes the definition of ratings of regions, forms and directions, assessment of risks and effectiveness of inter-territorial interaction and cooperation. It is argued that interaction and cooperation in this area can be realized through participation in investment for the creation of infrastructure facilities for waste management; through participation in tenders on the electronic trading platform for the purchase of secondary raw materials; construction of eco-industrial parks, allowing to reduce to the maximum the amount of waste going to landfill; awareness-raising activities to popularize the principles of closed-cycle economy; eco-volunteering, creation of an eco-monitoring system.Conclusions. The model of interterritorial interaction and cooperation in the sphere of waste management proposed by the author allows to improve its quality, to ensure the efficiency of territorial development, viability of waste management infrastructure, full utilization of the potential of regions and the sphere of waste management.

Single-Use Vape Batteries: Investigating Their Potential as Ignition Sources in Waste and Recycling Streams

This study investigates the potential link between the increasing prevalence of single-use vapes (SUVs) and the rising frequency of waste and recycling fires in the UK. Incorrectly discarded Li-ion cells from SUVs can suffer mechanical damage, potentially leading to thermal runaway (TR) depending on the cells’ state of charge (SOC). Industry-standard abuse tests (short-circuit and nail test) and novel impact and crush tests, simulating damage during waste management processes, were conducted on Li-ion cells from two market-leading SUVs. The novel tests created internal short circuits, generating higher temperatures than the short-circuit test required for product safety. The cells in used SUVs had an average SOC ≤ 50% and reached a maximum temperature of 131 °C, below the minimum ignition temperature of common waste materials. The high temperatures were short-lived and had limited heat transfer to adjacent materials. The study concludes that Li-ion cells in used SUVs at ≤50% SOC cannot generate sufficient heat and temperature to ignite common waste and recycling materials. These findings have implications for understanding the fire risk associated with discarded SUVs in waste management facilities.
