Globally, bio-diesel is gaining importance because of its environmental advantages. Jatropha curcas has been widely considered as a potential feedstock for the production of bio-diesel in several tropical countries. This study employs a method of data collection that is a face-to-face interview, along with a questionnaire. The questionnaire is designed, taking into consideration, different aspects of sustainable development. The survey is conducted in Kolkata, based on bio-diesel producing companies. Statistical analysis using SPSS version 17 is used for analysing the data collected from different bio-diesel producing companies from respondents of sample size 100 based on the questionnaire. Analysis of primary data collected is evaluated by chi-square and correlation tests. The results indicate that the relationship of design, maintenance, process capability, facility management, transportation, quality, technology, material, and human resource with sustainable development, is statistically significant and positively correlated. The major barriers that industries are facing relate to inadequate quality management, missing engine approvals and high raw material cost. Removal of tax hurdles and supportive legislative measures are the most efficient measures for overcoming these barriers.","PeriodicalId":13984,"journal":{"name":"International Journal of Environmental Technology and Management","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2019-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45401383","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}

Generally, uncontrolled release of these wastes has increased environmental concern mainly to the aquatic environment in recent years. In this study, an experiment of tea waste green composites was outlined to provide more knowledge and findings in utilising the tea waste as reinforcement. The current experimental investigation focuses mainly on the mechanical and characterisation of poly (lactic acid) (PLA) filled with household tea wastes (TW) green composites. The morphology properties of PLA with tea waste composites were characterised using scanning electron microscopy (SEM) and X-ray diffraction (XRD) methods. The results show that the addition of tea waste improved the mechanical properties of the composite nevertheless the crystalline structure was reduced due to the presence of tea waste particles. The study findings highly recommended that tea wastes should be environmentally managed and recycled for better utilisation as an energy source or in other valuable application to reduce the impact on environmental pollution.","PeriodicalId":13984,"journal":{"name":"International Journal of Environmental Technology and Management","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66767991","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}

Using panel data regression models, this study considered the impact of VCR from both, accounting and market-based perspectives. The quality of VCR is measured using the content analysis of disclosure indexes adapted from a list of disclosure items that were provided in various global warming, climate change, greenhouse gases, and carbon reporting guidelines, standards and frameworks. The finding indicated that on average, the quality of VCR was still low compared to the overall potential score. The findings also revealed that VCR generates a negative relationship with return on assets (ROA) and earnings per share (EPS). Nevertheless, VCRQ does not influence return on equity and Tobin's Q. This study has implications on both the policy and practice of organisations seeking to improve VCR practices.","PeriodicalId":13984,"journal":{"name":"International Journal of Environmental Technology and Management","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66768121","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}

This study aims to examine the antecedents of ERB among millennial tourists by proposing an extended model of ERB. Cross-sectional data from 386 cases were analysed using structural equation modelling and the results indicate that image, attitude, knowledge and consumption values have positive influence on intentions. Destination image and sound environmental knowledge turned out to be the main influences on their intention, with attitude and consumption values playing a minor role. This study also confirms that intention is a strong precursor of behaviour. This paper suggests the importance of providing educational programs as well as practising informative green marketing campaigns to encourage millennial tourists to behave responsibly.","PeriodicalId":13984,"journal":{"name":"International Journal of Environmental Technology and Management","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66767796","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}

Natural fibres that are diffused in the environment in abundance are economical, making this characteristic a value-added engineering, as they exhibit lower cost and can produce lighter composites, as compared to the existing fibreglass reinforced polymer composites. In this study, the involvement of kenaf fibre in chemical treatment on morphological and mechanical properties of the thermoset polyurethane (PU)-(PUKf) composites was firstly proposed and trialled. The results of chemical treatment on kenaf fibre highlight the improvement on the impact strength although the hardness of kenaf composites is reduced. This is compared with different samples, which are pure thermoset PU and kenaf fibre without chemical treatment. Overall, the developments of natural fibre in engineering and energy sectors could significantly enhance the reduction of solid waste and environmental pollution.","PeriodicalId":13984,"journal":{"name":"International Journal of Environmental Technology and Management","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66767890","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 plants used in this experiment were needed to survive in an indoor environment, hence only tropical, thermophilic plants which could grow in high humidity and warm temperatures with indirect sunlight were selected. An impedance tube of 100 mm dia. was used to calculate the direct incidence acoustic absorption coefficient of the plants and larger samples were tested within a reverberation chamber. The soil substrate used was a high porosity and low-density sample of perlite and coconut fibres. The results show that ferns and baby tears were good absorbers along with the soil substrate, whereas begonia was a better absorber at the lower and higher frequencies. The decibel drop by the fern with soil substrate is the highest with a decrease of frequency and the lowest is by Green Ivy which is due to morphological conditions.","PeriodicalId":13984,"journal":{"name":"International Journal of Environmental Technology and Management","volume":"61 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66767311","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}

This research aims to analyse water quality in the urban and agricultural area by conducting water sampling and in situ analysis. Water quality index (WQI), total nitrogen (TN) and total phosphorus (TP) were calculated and compared among different areas. Results for WQI shows that water quality at W7 deteriorates at class IV (33.5) compared to class II for another agriculture area. Meanwhile, another results showed that the WQ_02_AG transported significantly higher (14.9 mg/L) loads of TN than the urban area, but the phosphorus load was considerably lower (1.58 mg/L). Results for the urban area are slightly polluted and unsuitable for recreational purpose. In agricultural areas, water quality deteriorates due to sediment transport and nutrient infusion caused by agricultural activities. Therefore, powerful agricultural management practices for effective reservoir sedimentation management as one of the non-structural measures are recommended.","PeriodicalId":13984,"journal":{"name":"International Journal of Environmental Technology and Management","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66767559","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}
