New concept on the transformation of the zone of oil product pollution of the geological environment near of the «Olexandria» Arboretum (Bila Tserkva city, Ukraine)

In Ukraine, numerous geological environment sites are contaminated with lost oil products. Among them, there are many that have a long history of pollution transformation and accumulation. Due to the lack of long-term monitoring, much of the pollution history remains unknown, resulting in inadequate conceptual models that have a negative impact on the design of remediation projects. This article examines a solution to this problem, focusing on studies of the territory of the former Bila Tserkva aircraft repair plant (BARP), bordering the State Arboretum «Olexandria». Since 1990, various organizations have assessed geological contamination and proposed remediation strategies for the factory site and surrounding areas. The article provides information on the main results of the performed research. Emphasis is placed on clarifying the reasons for the sharp difference in the data of hydrogeological investigations conducted in 1990 and 2007. Initially, in 1990, liquid petroleum products (aviation kerosene) were detected only at the site of natural groundwater discharge in the upper reaches of the Western Ravine within the arboretum. On the plant’s territory, where there were undoubtedly sources of pollution and migration pathways of petroleum products in the soil, the presence of pollution was recorded only by the specific smell and color of core samples. However, during prospecting and exploration work in 2007 in the same area, three clearly defined lenses of light non-aqueous phase liquids (LNAPL) were discovered in sub-moraine sands. This phenomenon can be explained by the fact that the surface of groundwater, measured in 1990, dropped from a layer of moraine loams, where the mobility of light oil products is considered negligible, to sub-moraine sands, which are characterized by a much higher permeability.It should be noted that in the western part of the plant’s territory, where aviation fuel storage tanks were located, traces of contamination were found not only in sub-moraine sands and moraine loams, where the groundwater level fluctuates, but also in soils lying on the moraine. This supports the assumption that in the past, there were emergency releases (losses) of a large volume of fuel into the unsaturated soil layer and the subsequent relatively rapid lateral spread of the oil product in the aeration zone.

Pollution Sensitivity and Resistance Assessment of Native Ornamental Plants for Landscaping in Various Factories

The present study was conducted during 2023–2024 and the data was recorded during post monsoon period (January– February, 2024) to assess the performance of ten native ornamental plants under different pollutants of seven factory sites along with a control in Rayalaseema region of Andhra Pradesh, India, for recommending in green belt development under multiple polluted sites. The data recorded for various parameters under study showed that among the plants tested, Cordyline terminalis at Control site i.e. College of Horticulture reported maximum values for canopy spread (59.54 cm2), leaf extract pH (7.49) and total chlorophyll content (3.86 mg g-1), while it recorded maximum values for ascorbic acid content (13.00 mg g-1), relative water content (89.54%), proline content (9.19 µmoles g-1) and superoxide dismutase activity (4.23 O.D. min-1 g-1) at APMDC factory site. Barleria cristata recorded superior values for Stomatal Index (33.40%) at College of Horticulture (control site) and Chlorophyll stability index (98.04%) at polluted site of APMDC. Phenol content was reported highest in Ixora coccinea (18.96 mg 100 g-1) at mining site (APMDC). Nyctanthus arbor-tristis at APMDC site had reported maximum value for Dust capturing capacity (0.31 mg cm-2). The Data on specific leaf weight showed non significance difference. Cordyline terminalis with superior biochemical traits showed higher Air Pollution Tolerance Index (APTI) values (21.86) at APMDC mining site while, Nyctanthus arbor-tristis with an Anticipated Performance Index (API) grade of 5 has been assessed as a very good performer under polluted sites.

Assessment of occupational exposure to micro/nano particles generated from carbon fiber-reinforced plastic processing.

Carbon fiber-reinforced plastics (CFRP) are leading functional materials with superior strength and low mass density compared to metal. Our previous factory site analyses found that CFRP processing generates fibrous debris and fine micro/nano-sized particles of various shapes. The present interventional study was conducted at a factory located in Japan and evaluated debris consisting of various-sized particles generated during the industrial processing of CFRP, such as cutting, grinding, and turning of CFRP pipes, using real-time particle monitoring devices of the following: PM4 Digital Dust Monitor (DDM), handled Optical Particle Counter (OPC), Condensation Particle Counter (CPC), and Scanning Mobility Particle Sizer (SMPS). In addition, personal exposure of workers was evaluated using a novel wearable PM2.5-compatible device (P-sensor). First, we confirmed the presence of micro/nano particles in the dust generated during industrial processing of CFRP. Finer CFRP-generated particles were detected by the nanoparticle-compatible devices; CPC and SMPS, but not by OPC or DDM. The dynamic detection pattern of the P-sensor resembled that recorded by the nanoparticle-compatible devices. The novel wearable P-sensor can be used to measure finer particles generated by CFRP processing in occupational settings. Second, the exposure assessment was conducted twice and the levels of the micro/nano particles in the second survey were significantly (less than half) lower than that in the first survey. By avoiding immediate power-off of the exhaust system after operations, the scattering of particles was effectively reduced. Our results indicate that effective use of local exhaust ventilation system improves the workplace environment for particle exposure.

Kapabilitas Dinamik Pada Akselerasi Produksi Precast Girder Tipe- U pada Proyek LRT Jabodebek

LRT Jabodebek as the first LRT infrastructure project in Indonesia has provided lessons on the implementation of dynamic capabilities on manufacturing aspects for the construction industry. In order to meet the requirements 2900 units of U-Shape Girder, production under normal conditions is expected to be completed by 2020. The acceleration of completion led to a significant increase in project requirements, accelerated completion of construction led to production shortages. Meeting the need for acceleration requires factories to be able to increase their production capacity by using steam curing methods. This case study uses a qualitative approach and focuses on dynamic capabilities in the production process. As a role model of application of manufacturing dynamic capability, the project has demonstrated the role of technology in increasing productivity. The integration of methods, asset positioning, and management processes are the most dominant productivity factors in accelerating the production of U-Shape precast girder. Optimum production performance can be achieved by integrating factory roles, project sites and management supported by adequate resources and staff experience

Determination of Sustainable Factory Locations for the Lemon Agroindustry using AHP, Mapping and Water Management

This research was conducted in Suntenjaya Village, Lembang, and West Bandung Regency, focusing on lemon agro-industrial development. Research was conducted using the Analytical Hierarchy Process (AHP) approach, area mapping, and water management to determine a sustainable factory location. The main objective is the selection of factory sites by integrating lemon production, considering sustainable agriculture aspects, product aspects, and water conservation programs. The results of this study provide a strong foundation for sustainable agro-industrial development that will support sustainable agriculture, local economy, and environmental protection. The research also combined qualitative and quantitative elements with a mixed approach that included Focus Group Discussion (FGD) and AHP, and the results showed that integrated drainage management was the top priority, followed by sanitation, clean water, reforestation, and sustainable agriculture. Mapping of areas based on geographical characteristics, such as rainfall, slope, and soil type, provided a map of water infiltration rates, which became a key guide in planning water conservation programs. The ultimate location for the lemon agroindustry is half of Desa Suntenjaya, mostly from the center to the northern area, which needs to consider proximity to markets in Bandung Regency and City, easy access to sources of raw materials for lemons, water availability, adequate transportation infrastructure, access to energy sources, suitable climate for lemon growth, and the availability of adequate labor in the region.

Baring Bearma’s Bounty. Human and animal signatures in the Quaternary contexts of the Bearma Valley, Central India

The rich Palaeolithic and fossil records of the Narmada and Son Valleys dominate paleoanthropological research from Central India, in large part because of their well-preserved Quaternary deposits. While data from other river valleys is emerging, finding both lithics and fauna in close proximity remains rare and spatio-temporal inconsistencies make assessment of implications for the larger area challenging. Ongoing investigations along the Bearma, the largest tributary of the River Sonar, has yielded a low-density fossil assemblage across three localities and a proximally located Large Flake Acheulean (LFA) site. The small fossil assemblage currently consists of both cranial and post-cranial elements in differing states of completeness and preservation, likely a function of post-depositional impacts and the time elapsed since exposure. Many of the important large mammalian herbivore species belonging to bovid, equid, cervid and proboscidean taxa that are commonly found during the Late Quaternary of the Indian Subcontinent are represented, making the region worthy of comparison with neighbouring fossiliferous areas. The new Palaeolithic site encountered less than 500 m downstream from the fossil localities is almost exclusively LFA technology in nature made primarily on slabs of Vindhyan sandstone. Preliminary analysis of the collected artefacts indicates a focus on the production of large flake blanks and debitage products from large cores configured according to various unifacial and bifacial technological methods. The frequency of these elements suggests the use of the area as a factory site, while the unmistakable presence of bifaces and other tools warrant broader interpretations. With the current lack of stratigraphic and chronometric data on either assemblage, it is premature to draw any chrono-contextual associations between the fossils and artefacts. However, this ∼5 km stretch of the Bearma yielding two significant proxies presents an excellent opportunity to understand hominin behaviour during the Quaternary and fill both geographical and temporal gaps in Central India.

Additionally, to efficiently obtain location data for supplier factory sites in the distribution network, a coordinate extraction method based on image recognition technology is proposed. Finally, the scientific validity of this study is verified based on the actual case data, and the robust optimization ability of the algorithm is verified by numerical calculations of different examples. This research not only enriches the study of green vehicle routing problems but also provides valuable insights for the industry to achieve cost reduction, efficiency enhancement, and sustainable development in reverse logistics.

Tunnel excavation slag volume measurement using triple-line structured-light vision: Rectification and optimization

The precise measurement of excavated tunnel slag volume is crucial for tunnel boring machine construction security and optimizing. Structured-light vision measurement method is a widely employed method for volume measurement of convey belt, comprising a camera and laser projector. However, maintaining alignment between the structured light plane and the belt is challenging, especially with machine vibrations, leading to significant errors in slag volume measurement. To address this problem, we propose an innovative excavated tunnel slag volume measurement method based on triple-line structured light vision. After capturing images with multiline structured light, our approach encompasses extracting centerlines, profile three-dimensional conversion, calibrating profile distortions with arbitrary structured light layouts, and registering to obtain the area of the structured light section. Finally, integral calculations along the movement speed of conveyor belt yield accurate, real-time measurements of tunnel slag volume. Extensive experiments in factory and construction site settings confirm the real-time capabilities, accuracy, and universal applicability of our approach.

Impact of diseconomy of mixed land-use on factory land redevelopment in large urban area: Evidence from Japan

Factory location in large urban areas is more difficult today as the sites are more likely to be used for residential and commercial facilities. This study investigates factors behind factory land use change, based on the redevelopment theory. Estimation is made using 1,824 land-use data in Osaka, a large urban area in Japan, between 2013 and 2018. Our new insight is that the diseconomy of the mixed land-use greatly impacts the land redevelopment of factory sites. In addition, the loose restriction of zoning districts and lack of localization economies of the factory also promote factory land redevelopment.

Analysis of place-based factors in transitions through the lens of a transition space: Insights from Finland’s emerging battery industry

ABSTRACT Battery production plays a crucial role in Europe’s electrification of mobility and production facilities are expected to play an essential role in European value chains in the future. However, this new trend in energy transition raises the question of how individual places and regions can tap into these developments and operationalise multilevel transitions based on their existing capabilities and assets. The purpose of the article is to advance the nascent theorising on the concept of transition space in the geography of transitions literature by studying place-based factors and their various interactions with transition levels. The authors studied the ongoing development of the GigaVaasa battery factory site located in Finland’s Vaasa region to explore which factors appeared most relevant in transitions and at which transition levels those factors manifested. The results indicate that place-based factors connect with different transition levels in a transition space, thus enhancing their possibilities for leveraging transition pathways. The authors conclude that strategic planning and the ability to mobilise stakeholders for systemic agency form a critical starting point for successful transition space management.

Partial Discharge Monitoring of Power Transformers by Calibrated UHF Measurements

Partial discharge (PD) measurement is an established technique to detect local defects in the oil/paper insulation. They can be measured by electrical PD measurements according to IEC 60270 or by electromagnetic measurements in the ultra-high frequency range (UHF: 300 MHz – 3 GHz). The electromagnetic emissions of PD are recorded using an UHF sensor which is inserted into the transformer tank. The importance of PD measurements is reflected in the standard for charge-based electrical measurements (IEC 60270). Because of the standard, apparent charge, QIEC, became an essential factor for determining insulation quality in transformers. To be an accepted factor for both, quality testing in factory acceptance tests (FAT) or site acceptance tests (SAT) and continuous PD monitoring, the UHF technology must be as reliable and reproducible as the electrical method. To achieve this, a standardized calibration procedure is needed: It makes UHF measurement results from different systems comparable. Because this calibration procedure was lacking in the past, the UHF technology does not provide comparability between measurement systems and different sensors, yet. However, it shows advantages for on-site acceptance tests like SAT, continuous monitoring, and diagnostic purposes. E.g., regarding signal to noise ratios, the possibility for localization of PD sources and also for practical reasons like preparation times and accessibility on-site. This contribution presents a PD monitoring system which can be calibrated according to the calibration process described recently in Cigré TB 861 and two different types of UHF PD sensors for power transformers. One sensor type is for new transformers using dielectric windows and the other is for retrofitting transformers using their DN50/80 drain valves. A recommendation or strategy on where to place window-type UHF sensors at the tank of new power transformers is also provided in accordance with TB 861. Additionally, this contribution provides a description of the calibration process for UHF PD measurement systems consisting of two steps: 1) Calibration of the measurement instrument analogous to the calibration of the electrical PD measurement circuit using a defined reference signal. 2) Calibration of a UHF sensor using its characteristic antenna factor (AF). Furthermore, it shows three case studies from different power transformers equipped with UHF sensors and UHF PD monitoring systems.

Assessment of heavy metals in rainfall as an indicator of air pollution from Erbil Steel Factory in Iraq.

The goal of the current study is to evaluate the heavy metal rainfall contamination in the vicinity brought on by the Erbil Steel Factory in Iraq during the study period. The study's findings revealed the concentration of all studied heavy metals in the precipitation near and around the factory is significantly higher than that of the rural area of Barzan village which is used as a control site. The average concentration of the metals is in descending order manganese (Mn) > lead (Pb) > iron (Fe) > arsenic (As) > cobalt (Co) > selenium (Se) > mercury (Hg) > and cadmium (Cd) for the polluted site. The geo-accumulation index (I-geo) of the heavy metal Mn in the rainfall around the steel factory site is 6.28 > 5 which indicates extreme contamination. While the Igeo values of Cd, As, and Fe are 4.87, 4.54, and 4.04 > 4 that indicate heavy to extreme contamination, for Pb, 3.80 > 3 indicates moderate to heavy contamination, Cd 1.68 > 1 indicates moderate contamination, Hg 0.46 > 0 indicates uncontaminated to moderate contamination, and Se - 0.36 < 0 indicates uncontaminated. The pollution load index (PLI) of the rainwater around the steel factory site is 13.46 > 1, demonstrating that the area is highly metal-contaminated.

Derivation of human health and odor risk control values for soil ammonia nitrogen by incorporating solid-liquid partitioning, ammonium/ammonia equilibrium: A case study of a retired nitrogen fertilizer site in China

Nitrogen fertilizer supports agricultural intensification, but its manufacturing results in substantial contaminated sites. Ammonia nitrogen is the main specific pollutant in retired nitrogen fertilizer sites with potential human health and odor risks. However, few studies focus on ammonia nitrogen risk assessment at contaminated sites, particularly considering its solid-liquid partitioning process (Kd) and ammonium/ammonia equilibrium process (R) in the soil. This study took a closed nitrogen fertilizer factory site as an example and innovatively introduced Kd and R to scientifically assess the human health and odor risk of ammonia nitrogen. The risk control values (RCVs) of ammonia nitrogen based on human health and odor risk were also derived. The maximum concentration of ammonia nitrogen was 3380 mg/kg in the unsaturated soil, which was acceptable for human health because the health RCVs were 5589 ∼ 137,471 mg/kg in various scenarios. However, odor risk was unacceptable for RCVs were 296 ∼ 1111 mg/kg under excavation scenarios and 1118 ∼ 35,979 mg/kg under non-excavation scenarios. Of particular concern, introducing Kd and R in calculation increased the human health and odor RCVs by up to 27.92 times. Despite the advancements in ammonia risk assessment due to the introduction of Kd and R, odor risk during excavation remains a vital issue. These findings inform a more scientific assessment of soil ammonia risk at contaminated sites and provide valuable insights for the management and redevelopment of abandoned nitrogen fertilizer plant sites.

Contamination Characteristics and Ecological Risk of Antibiotics in Contaminated Sites of Typical Pharmaceutical Factories in China

To understand the contamination characteristics and ecological risk of antibiotics in contaminated fields of pharmaceutical plants， samples of the surface soil， soil column， wastewater treatment process water， ground water， and residue dregs were collected from two typical antibiotic pharmaceutical plants in South and North China. A total of 87 commonly used antibiotics were quantified using ultrasound extraction-solid phase extraction and ultra-high performance liquid chromatography-mass spectrometry. The results showed that a total of 31 antibiotics of five classes were detected in all types of samples， and the maximum concentrations at each sampling point in the surface soil， soil column， residue dregs， wastewater treatment process water， and groundwater were 420 ng·g-1， 595 ng·g-1， 139 ng·g-1， 1 151 ng·L-1， and 6.65 ng·L-1， respectively. Most of the antibiotics were found in the surface soil， showing a decreasing trend with the depth of the soil column. The ecological risk assessment indicated that sulfamethazine， sulfaquinoxaline， tetracycline， chlorotetracycline， and D-sorbitol were at higher risk. Improving the efficiency of antibiotic removal from pharmaceutical wastewater and preventing production shop leaks are effective measures of controlling antibiotic contamination into and around fields in pharmaceutical plants.

Supply chain sustainability initiatives at Bajaj Electricals Limited to achieve Zero Waste to Landfill

&lt;p&gt;&lt;strong&gt;Subject area:&lt;/strong&gt; This case allows management students to engage with the implementation of sustainable supply chain management practices both at the macro and micro levels. The decision to make supply chain operations sustainable is no longer an option for many organisations. The question is not “should we do it? but how can we implement sustainable supply chain management practices?” &lt;strong&gt;Study level/applicability:&lt;/strong&gt; This case has been developed for management institutes and schools that teach undergraduate and postgraduate programmes. Sustainability has become an essential module in management curriculums; thus, this case is relevant for management programmes (operations, logistics, supply chain management, business studies, and management). &lt;strong&gt;Case overview:&lt;/strong&gt; This case highlights the achievements of Rameshwaram (plant head at the Nirlep factory of Bajaj Electrical Ltd.) and his team for successfully completing a sustainability initiative—Zero Waste to Landfill (ZWTL)—in a short span of six months. This case is divided into two parts: the first part presents their initiatives in making all echelons of their supply chain sustainable; the second part specifically outlines how they achieved Zero Waste to Landfill in one of the manufacturing operations in a short span of six months. A cross-functional team was put together to plan and implement the ZWTL project. Initially, the team encountered many challenges, such as poor quantification of waste at the factory site, inadequate infrastructure for waste segregation, a lack of vendor participation, and extensive training of vendors and employees as needed to ensure project compliance. However, with sustained efforts, the goal was achieved. As a result, BEL became the first Indian company in the sector to achieve 99% diversion from landfills for the waste generated at the Nirlep factory in 2021. It translated into a dramatic reduction of adverse environmental impacts. Monetary benefits were also realized by utilizing the waste for commercial use. As customers across the globe appreciated their efforts, their brand equity increased severalfold. &lt;strong&gt;Expected learning outcomes:&lt;/strong&gt; The case establishes that supply chain sustainability initiatives can never be completely successful without the unanimous engagement of internal and external stakeholders. In present times, the foundation of business performance has moved away from financial profitability only to the “triple bottom line,” which incorporates environment and social responsibility. The choice between commercial viability and sustainability is no longer available to the companies, as they need to integrate environmental and social goals within their businesses and provide transparency on sustainable performance and value to not only all stakeholders but also policymakers and consumers.&lt;strong&gt;&lt;/strong&gt;&lt;/p&gt;

Analysis and optimization of industrial engineering and management operating environment based on human factors engineering

Abstract In today’s society, which attaches great importance to humanization, human factors engineering has become a hot topic of research in industrial engineering to improve enterprises and factory sites. This paper aims to optimize the efficiency of industrial engineering by adopting industrial engineering (IE) methods, combing the methodological study of the production process and applying job measurement methods to improve engineering efficiency. The study results show that after the improvement of two-handed operation, the left and right-handed operation time is reduced to 25.78 seconds, which is 31.8% lower compared to the pre-improvement period. The overall process was optimized to minimize the bottleneck beat time from 1.379 seconds/piece to 1.333 seconds/piece, and the maximum production capacity increased from 51,308 pieces/day to 52,204 pieces/day. In addition, labor requirements in the industrial workflow were reduced by 20%, from 610 to 486 people. As for the improvement of the operating environment, the noise levels were kept below 73.9 dB(A), especially for the dust collector, which was significantly reduced from 86.4 dB(A) to 72.9 dB(A). This optimization of industrial engineering and its operating environment by applying human factors engineering principles ensures the production quality. It achieves the maximum output with minimum resource input, laying a solid foundation for the continuous optimization of industrial engineering.

Crip Life Amidst Debilitation: Medicalization, Survival, and the Bhopal Gas Leak

In a textbook horror-story of global capitalism, on December 3, 1984, the U.S owned Union Carbide pesticide factory spewed forty tons of lethal toxic methyl isocyanate (MIC) on the city of Bhopal in India. Nearly 10,000 people died and 30,000 people were disabled overnight. Continued exposure to MIC at the factory site has disabled many more in the decades since. Yet, few disability scholars have considered the histories of the survivors of the leak as a key site of crip politics. Drawing on work by Nirmala Erevelles, Jina Kim, Jasbir Puar, and Alison Kafer, this paper explores how the long history of debilitation, disablement, and survivorship since the Bhopal Gas Leak provides essential ground for re-zoning disability studies in the Global South. Braiding the theory of debility with the methodology of critical disability studies, this article posits that it is insufficient to say that the most marginalized in the Global South experience debility. Rather, it is also necessary to focus on their modes of survival in the face of the constant material and intellectual reproduction of said debilitation. The article demonstrates how poor lower-caste and Muslim workers and city-dwellers in Bhopal were subject to the debilitating logics of transnational corporate negotiations, racialized environmental de-regulation, and governmental profit-seeking in the years leading up to the leak. Through crip readings of medical research published between 1985 and 2000, I argue that this debility has been compounded through knowledge production which did not pay heed to the ways in which its victims contended with their vulnerability. In contrast to these sources, this article further examines testimonies and organizational pamphlets to contend that survivors in Bhopal offer their own model of disability justice and crip survival in the face of debilitation. In an era of vibrant disability rights organizing in the United States, the survivors of the leak emerged in global media primarily as victims of a tragedy caught in an endless cycle of injustice. Moving past the stance of pity often deployed in discussions of Bhopal, I highlight efforts of survivance that center disabled futurity, even as these activists use a different vocabulary and thereby strive to channel attention and resources to the myriad forms of crip survival in postcolonial India.

Site selection decision for biomass cogeneration projects from a sustainable perspective: A case study of China

Biomass energy has made significant contributions to energy demand and environmental protection. The purpose of this study is to establish a new integrated method adapted to the site selection of biomass cogeneration projects. The highlight lies in the integration of Multiple Criterion Decision Making methods with Geographic Information System at different stages. This study takes Henan Province as an example to introduce the application of this model. Stage I preliminary screening stage: use Geographic Information System and Fuzzy Best Worst Method to classify the suitability level of project site selection within the research area. Identify alternative solutions in areas with high suitability and large patch area. Stage II selection stage: Calculate the indicator weights using Criteria Importance Through Intercriteria Correlation method first; Then use the Multi-attributive Border Approximation Area Comparison method to select the optimal factory site. Using geographic information system technology, the factory is selected to be built in an area with a suitable value greater than 7 in Xiangcheng County, Zhoukou City. Finally, the obstacle model diagnoses the direction of optimizing the location environment. This study provides a theoretical reference for the new construction, renovation and expansion of biomass cogeneration projects.
