Assessment of phytoremediation potential of native plant species naturally growing in a heavy metal-polluted industrial soils.

The present study was carried out in Hayat Abad Industrial Estate located in Peshawar to assess the levels of cadmium (Cd) that were present in the soil as well as the plant parts (Roots and shoots). To evaluate the phytoremediation potential of the plants different factors i.e. Bioconcentration Factor (BCF), Translocation Factor (TF), and Bioaccumulation Coefficient were determined. These plants were grown in their native habitats (BAC). We have analysed, cadmium concentration from soil which are collected from 50 different locations ranged from 11.54 mg/Kg (the lowest) to 89.80 mg/Kg (highest). The maximum concentration (89.80 mg/Kg) of cadmium was found in HIE-ST-16L Marble City and HIE-ST-7 Bryon Pharma (88.51 mg/Kg) while its minimum concentration (12.47 mg/Kg) were detected in the soil of Site (HIE-ST-14L Royal PVC Pipe) and (11.54 mg/Kg) at the site (HIE-ST-11 Aries Pharma). Most plant species showed huge potential for plant based approaches like phyto-extraction and phytoremediation. They also showed the potential for phyto-stabilization as well. Based on the concentration of cadmium the most efficient plants for phytoextraction were Cnicus benedictus, Parthenium hysterophorus, Verbesina encelioides, Conyza canadensis, Xanthium strumarium, Chenopodium album, Amaranthus viridis, Chenopodiastrum murale, Prosopis juliflora, Convolvulus arvensis, Stellaria media, Arenaria serpyllifolia, Cerastium dichotomum, Chrozophora tinctoria, Mirabilis jalapa, Medicago polymorpha, Lathyrus aphaca, Dalbergia sissoo, Melilotus indicus and Anagallis arvensis. The cadmium heavy metals in the examined soil were effectively removed by these plant species. Cerastium dichotomum, and Chenopodium murale were reported to be effective in phyto-stabilizing Cd based on concentrations of selected metals in roots and BCFs, TFs, and BACs values.

Wastewater leakage identification in WWTP and concrete pipelines using integrated geophysical imaging methods

Industry and mining activities covers a broad spectrum of processes that dispose an abundant amount of wastewater. Given the vast array of industries, there are equally large number of heavy metals, organic solvents, and hydrocarbons pollutants associated with its wastewater, posing a great threat to aquifers, especially groundwater. Main contributor of this polluting scheme are from the leakage of underground/surface storage tanks, effluent pipework, industrial sewers, and waste injection system. To ascertain the presence of pollution in the subsoil and groundwater resources, an integrated geophysical method can be the alternative of non-invasive methods. The presence of contaminants in subsoil alters the physical properties of rock formations and decrease pore-water resistance, therefore it can be mapped by geoelectrical resistivity. In this paper, study case was conducted in Medan Industrial Estate, Indonesia, to identify potential leakage under the Wastewater Treatment Plant (WWTP) and its pipework, using Geoelectrical Wenner and Magnetotelluric Method with 5 lines in the interval of 40-60 meters and Magnetotelluric Method throughout the 175 meters of pipework in the production area. Based on the Geoelectrical Method, an anomaly with a low resistivity value was detected within 7 meters of the ground depth. Meanwhile, in the Magnetotelluric Method, a moderate permittivity value was detected that is local and located within 2 meters depth which is where the pipe and the bottom of the WWTP storage tank is located. In conclusion, based on the results obtained from the Geoelectrical and Magnetotelluric Methods that have been carried out in the WWTP area and along the wastewater pipeline leading to the WWTP, no anomalies were found that lead to waste water leakage.

Analysis of Cooling Loads and their Effects on Energy Costs for an Integrated Insulating Materials-Based Direct Iron Processing Plant

This study discusses the surge in energy consumption in the Caribbean region over the past decade, notably in Trinidad, where per capita consumption exceeds 6500 kWh. In response to rising electricity tariffs, energy sector entities are implementing conservation initiatives. The study focuses on a Direct Reduced Iron (DRI) plant in Trinidad's Point Lisas Industrial Estate, specifically examining alternatives to conventional air conditioning in a DRI processing laboratory. Various insulating materials were simulated using CHVAC software and evaluated against a 5-ton air-conditioning unit using the CLTD method. Analysis reveals standalone use of insulating systems in the laboratory is impractical due to orientation, location, and internal heat loads, necessitating a hybrid cooling system. Economically viable configurations involve a 3-ton A/C unit paired with PVC, foam, or fibreglass walls and ceilings. Despite higher initial costs, configurations with a 3-ton unit offer savings in maintenance and electricity. Findings extend beyond the laboratory, potentially influencing passive cooling material adoption and active cooling load reduction in other contexts, thus promoting sustainable energy practices.

The Relationship Between Inter-Legality and Organized Social Processes in Land Formalization Practices in The Sovereignty-Contested Area of Tanintharyi Region, Myanmar

The study considers the Dawei Special Economic Zone (DSEZ) project, which was a land formalization case in a sovereignty-contested area conducted by de jure Myanmar state, de facto Karen Nation Union (KNU), and an international developer. The DSEZ project planning comprised deep-sea Ports, 250 sq. kms of industrial estate zone, and the two-lane 148 km road linking Dawei in Myanmar and Kanchanaburi Province of Thailand as its main features. Recent studies of Myanmar land institutions in sovereignty-contested areas have mainly discussed the factor of "inter-legality," the integration of non-state land laws, as the solution for land disputes between the central state and armed ethnic political groups. However, the real-world case in this study indicated a second factor, "organized social processes," working in correspondence with the first factor. This research paper explores how the two factors were used together the integration of customary land practice into statutory property institutions, influencing changes in the structure and process of land formalization practices, and illustrates the unclear property institutions of sovereignty-contested frontiers. This research paper is a single case study that benefited from the researcher's five years of work experience in the DSEZ project's design, planning, and land acquisition. The obtained information comprises the project's land formalization documentation, published land laws which were checked with the project manager using the triangulation method, and local newspaper clippings. The study concludes that inter-legality and organized social processes should be used together in practice planning to form more context-oriented land formalization practices, employing collective community memory to reduce institutional inertia. Furthermore, the mutually-agreed standards can help avoid direct power contestation between the de jure and de facto.

Quantifying circularity factor of waste: Assessing the circular economy potential of industrial zones

This study offers essential metrics for informed decision-making in the context of transforming traditional industrial estates into circular economies. The study conducts a systematic analysis of an existing industrial zone, demonstrating its potential transition towards a circular approach while assessing its economic viability and avenues for enhancement. The paper unfolds as follows: It initially presents a comprehensive methodology for quantifying the economic value added through recycling within the industrial zone. Subsequently, it introduces a method to compute the economic value associated with the remaining waste generated within the industrial zone. The paper then proposes a novel approach for determining the circularity factor of an industrial zone, effectively quantifying the degree of circularity achieved within the zone. Finally, it integrates circular economic principles and outlines a framework to assess the circularity value across the entire manufacturing process, reducing waste and reintegrating it into the material supply chain. The study provides a robust methodology for calculating circular value addition within an industrial zone. Furthermore, these metrics are applied to Biyagama Export Processing Zone (BEPZ), in Sri Lanka as part of the study's empirical analysis. The circularity factor of the zone was 0.4, and it clearly identifies that the total economic value addition of the zone can be maximized through the practice of a circular economy.

Sustainable planning and design for eco-industrial parks using integrated multi-objective optimization and fuzzy analytic hierarchy process

ABSTRACT The increasing growth of industrial facilities calls for sustainable planning and design. In this research, the multiple objective optimization model is developed to plan for Eco-Industrial Parks, in which economic, social, and environmental criteria are evaluated. Our proposed optimization model is integrated with the simulation-based risk profile based on emergency scenarios. Varied chemical substances and explosive locations are further analyzed to assess the impact of risk. Then, the Fuzzy Analytic Hierarchy Process technique is applied to examine uncertain decisions. Next, this study presents the proposed model with the case study of selective industrial-building types in an industrial park, in which industrial plants, hazardous material plants, warehouse buildings, and office space are included. Our analysis reveals that tradeoffs exist in designing an industrial estate with various industrial plants under conflicting objectives. Finally, tradeoffs are investigated using Pareto analysis resulting in sustainable planning for an industrial estate.

Model the complexities in inventories: the case of Tradeasia

Learning outcomes Upon completion of the case study, the students will be able to find the challenges and underlying structures that cause the problem; the students will be able to identify the dynamic variables and develop the interconnection and interlinkages among the time-delayed variables to build the story of the business case; the students could develop the block diagram and could build the system dynamics model using the simulation software STELLA, and if they do not have the simulation software, even then they could have a mental model to understand the problem well; the system dynamics students can design the policies to make the system better behaved and recommend solutions; and the students could make mind maps and develop the mental model and could recommend solutions and way forward to overcome the challenges and solve the issues. Case overview/synopsis Tradeasia is a small-scale manufacturing firm that had started its business activities near Sundar Industrial Estate, Raiwind, in September 2007. The company’s prime focus was to buy the potato starch from chips manufacturing companies and, then, extract the potato starch from the waste potato using its own machinery and sell it as a sizing agent to textile mills. Quality characteristics in terms of better millage and enhanced gullibility made it compatible with Rafhan corn-based starch. The major challenge linked to potato starch was its degree of wetness; the potato starch either extracted from rotten potato or procured from the potato chips manufacturing companies had a high degree of wetness and moisture content. Wet potato starch sometimes had more than 60% moisture content, which was really a challenge. Owing to the high degree of wetness, the wet starch was prone to fungus growth, and within hours, the fungus created toxins if it was not dried immediately, and then after 24 h, toxins acquired a black colour, and they became hardened like pebbles. The starch then was unusable even for sizing purposes for textile products. Reduction in the degree of wetness was really a big challenge and demanded prompt action and high productivity of the operational staff to make that product dry for sale purposes. This was the biggest challenge that ended up in huge inventories of wet starch. Capacity constraints and operational inefficiency killed the company’s productivity and affected the company’s profit. Complexity academic level This case study is written and developed for MBA and MS-level supply chain students of the system dynamics course or those studying management of supply chain complexities. This case study discusses the operational challenges while running the business; huge inventories, capacity constraints and inefficiency in production operations were the challenges associated with almost all manufacturing industries. This case study discussed not only why such challenges are appearing in the business but also the solution that resided in the wisdom shared by the employees in the board meeting. An integrated system dynamics model could be used to design the policies to overcome such challenges. Even the block diagram of the model and causal loop diagram could help to conceptualize the problem and explore the way forward.

BRYOPHYTE DIVERSITY AND ATMOSPHERIC POLLUTION IN A RESIDENTIAL AREA AND AN INDUSTRIAL URBAN FOREST IN JAKARTA, INDONESIA

Bryophytes are nonvascular plants that have simple structures that are sensitive to environmental changes, and they can, therefore be used as indicators of air quality. The presence of bryophytes in disturbed urban ecosystems, such as residential and industrial areas, indicates that their structures have adapted to survive in such areas. The objective of this study was to compare the bryophyte diversity and air quality indices between a residential area and an industrial area in Jakarta. The research was conducted in the Bona Indah residential area in South Jakarta and the Jakarta Industrial Estate Pulogadung (JEIP) urban forest. Sampling was carried out using the transect method in the residential area and the quadratic method in the urban forest on three different substrates, namely rocks or concrete, soil and tree trunks. The percentage of the epiphytic bryophyte cover was measured using a 10 × 10 cm subplot. Voucher specimens were stored at the Herbarium UI DEP and Herbarium IPB. Twenty-one species of moss and three species of liverwort were found in the two locations. Bryophytes were found on all the substrates in the residential area, but in the urban forest, they were found only on tree trunks and rock/cement substrates. Based on the Shannon–Wiener Index, although both locations had moderate bryophyte diversity, the residential area’s bryophyte diversity was higher than that of the urban forest. The index of atmospheric purity in the residential area was 4.3, indicating a high level of pollution, and it was 0.3 in the urban forest, showing that it was also very polluted.

Evaluation of the Air Pollutant Standard Index (ISPU) parameter concentration limits in industrial estates on Java Island

Due to the harmful effects of air pollution on health, outdoor air pollution standards are getting stricter. Because of environmental changes, the Minister of Environment and Forestry Regulation No. 14/2020 must reevaluate the concentration limits for ISPU parameters. This study aimed to examine the concentration ranges and ISPU values for SO2, NO2, CO, O3, and PM10 in industrial estates on Java Island, and set concentration limits for five relevant ISPU parameters based on the results of monitoring, sampling, and toxicity studies. A drop in the average concentration of the five ISPU parameters in 2022 compared to monitoring from 2015 to 2019 shows that the air quality in industrial estates on Java Island is improving. The ISPU values between 10 and 56 are in the good-to-moderate range, which means that the air quality is still good enough for the health of humans, animals, and plants. The relevant concentration limit recommendations for ISPU in good-to-moderate categories for SO2, NO2, CO, O3, and PM10 were 42–77 μg/Nm3, 29–120 μg/Nm3, 3519–5037 μg/Nm3, 33–97 μg/Nm3, and 29–82 μg/Nm3, respectively. The results of this study can be used to improve Indonesia’s ambient air quality index system (ISPU).
