So far, it has been used for analysis at national and regional levels; however, the EMA has not been utilised in a business performance analysis context. When used in a business context, EMA reveals the interface between industrial activity and the environment. EMA analysis can provide opportunities in measuring the social, economic, and environmental performance of the industry in a sustainability context. Unlike other evaluation methods, which are ‘demand-side’ or ‘user-side’ concerned, EMA analysis is a ‘donor-side’ approach. This research work illustrates the selection of suppliers based on the amount of emergy consumption. Emergy indicators, such as Emergy Yield Ratio (EYR), Emergy Sustainability Index (ESI), Environmental Loading Ratio (ELR), Emergy Self-support Ratio (ESR), Renewability percent (%R), Emergy flow Density (ED), and Emergy Investment Ratio (EIR) are estimated. The results show that there is enough room for improving emergy performance in the tannery industry. The result also highlights a significant variance in the input of indigenous renewable and non-renewable resources and imported resources among the investigated tanneries. Based on the outcomes, the study provides insights on the industries’ consumption of renewable and non-renewable resources.","PeriodicalId":14400,"journal":{"name":"International Journal of Sustainable Engineering","volume":"15 1","pages":"1 - 14"},"PeriodicalIF":3.7,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49365188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The found degradation rate is in agreement with other values obtained for different power plants using the same method and having close characteristics. The degradation value is determined from the slope of the annual change in the performance ratio corrected regarding the temperature. The yearly performance ratio varying between 84.12% and 90.54% is higher in spring and lower in the summer with an average value of 87.18%.

Hammadi","doi":"10.1080/19397038.2021.1941392","DOIUrl":"https://doi.org/10.1080/19397038.2021.1941392","url":null,"abstract":"ABSTRACT A theoretical study of humidification-dehumidification (HDH) processes inside a system combining a solar still with an earth-air heat exchanger and a solar chimney was introduced. Energy and mass balances in a transient mode for the solar still and the earth-air heat exchanger in addition to the solar chimney were formulated and numerically simulated. The solar radiation heats water in the solar still basin, which in turn warms and humidifies dry air entering the solar still due to the heat and mass transfer into the airstream. When the glass/or the EAHE pipe wall temperatures are lower than or equal to the dew point of the humid air, the vapour condenses and runs down. The results show that the water, the air, and the glass temperatures increase with time to reach their maximum values (66.9 oC,61.8 oC, and 61.24 °C respectively) in June from 15.00 to 16.00. The humidity ratio along with the solar still length increases to reach a uniform value whenever the moist air is saturated. At the same time, the humidity ratio along EAHE decreases due to the condensation of the moisture inside the EAHE pipe. The condensation rate in the EAHE decreases gradually along a pipe length of 70 m until it completely vanishes at the pipe outlet. The hourly condensation rate in the EAHE attaining its maximum value of 49.27 kg/hr. at 14:32 (Basra local time) in June where the solar radiation is at maximum value. Also, the results indicated that the productivity of freshwater in the solar still is strongly affected by the water, air, and glass temperatures. The maximum productivity in the solar still achieved in March was 157 kg/day while it was 369 kg/day in July for the EAHE. The increase of the air velocity increases the productivity in EAHE and decreases it in the solar still. The daily average freshwater production for the system (solar still and the earth-air heat exchanger) throughout the year was found to be 207.44 kg. The thermal efficiency of the system over the interval from 6:00 to 19:00 was found to be 0.23–0.55. The economic evaluation showed that the cost of freshwater production was 0.0282 $/kg. A comparison of the current analysis with other works showed a good agreement.","PeriodicalId":14400,"journal":{"name":"International Journal of Sustainable Engineering","volume":"14 1","pages":"921 - 932"},"PeriodicalIF":3.7,"publicationDate":"2021-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19397038.2021.1941392","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46019449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, the present research reports the use of biodiesel derived from Waste Ayurvedic Oil (WAO) in an off-road twin cylinder compression ignition engine. The methyl ester of WAO was formulated using the ultrasound irradiated transesterification process. The different blends of WAO methyl ester and diesel, say WAO10, WAO15 and WAO20 were prepared and experimented on a Mahindra-Maximo twin cylinder tractor engine in order to analyse its performance, emission and combustion behaviour. As compared to diesel, WAO blends offer increased specific fuel consumption with comparable brake thermal efficiency for WAO10 over all the engine speeds. WAO10, WAO15 and WAO20 diminished CO emissions by 16.12%, 22.58% and 29.03%, HC emission by 19.04%, 42.8% and 61.9% as well as smoke opacity by 14.28%, 28.57% and 42.85% together with amplified NOx emission by 2.73%, 10.95% and 21.5% respectively in comparison with diesel. Therefore, WAO is a cost-effective feedstock for biodiesel synthesis, and its blends could be used as off-road diesel engine substitutes.","PeriodicalId":14400,"journal":{"name":"International Journal of Sustainable Engineering","volume":"14 1","pages":"2126 - 2136"},"PeriodicalIF":3.7,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46968620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main results showed that the proposed model was able to increase the company’s schedule performance. For the scenario analysis, two-hybrid heuristics were compared: NEHS-1 and NEHS-2, and both showed better schedule results than the classical NEH. However, the best results were presented by the NEHS-2, and it should be further improved with local search heuristics, in future research.","PeriodicalId":14400,"journal":{"name":"International Journal of Sustainable Engineering","volume":"14 1","pages":"1665 - 1679"},"PeriodicalIF":3.7,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48966355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But how can this be done, and what can be done to bridge the gap from current affairs to a new, more sustainable state? Looking towards industries with experience might help making the first step just a little bit easier. This study aims to find challenges and bottlenecks when working with sustainable materials, in order to help companies interested in transitioning towards using sustainable or renewable materials in their products. The paper describes an interview study with five Swedish wood industry companies, differentiated in size and products, where the authors identify several key findings for both industry (already working with wood or aiming at transitioning towards renewable materials) and academia (on using renewable materials, need for further research, and pointers for teaching design and engineering students). Findings range from how organisational culture affects material selection, to how flexibility and efficiency effects automation solutions via how these companies have approached outsourcing of parts of their production.","PeriodicalId":14400,"journal":{"name":"International Journal of Sustainable Engineering","volume":"14 1","pages":"1980 - 1987"},"PeriodicalIF":3.7,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43906168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fewer evidence was provided regarding CSR in pharmaceutical sector due to the characteristics of such firms. In this paper, we shed light on CSR disclosures’ practices adopted by Hikma Pharmaceutical (Plc.). Based on previous literature in the field, we adopt a content analysis of Hikma Plc. CSR disclosures related to the three main fields defined by the Global Reporting Initiative (GRI) standards 2016: Economic standards (GRI 200), such as values of integrity, business ethics through anti-corruption practices, and competitiveness through tax optimisation. Environmental standards (GRI 300), especially ISO14001 certification that specifies the requirements for an environmental management system that an organisation should use to be considered as environmentally responsible. Social Standards (GRI 400), especially those that respect and uphold the principles of human rights of the UK Modern Slavery Act (MSA). Our results show that Hikma Plc. displays a higher level of compliance with GRI international standards, mainly in the social field more than economic and environmental disclosures. Our study can be used as a useful framework for CSR disclosures in the pharmaceutical industry in Jordan and abroad. Our findings help in guiding investors when allocating resources in the pharmaceutical industry and regulators when issuing new standards on CSR policy.","PeriodicalId":14400,"journal":{"name":"International Journal of Sustainable Engineering","volume":"14 1","pages":"1572 - 1586"},"PeriodicalIF":3.7,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43849499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
