The issue gets significant, when the vehicles that outset from multiple depots, collects the BMW from hospitals scattered around a region and carry the waste to multiple disposal sites. The present paper deals with the development of a modified ACS-based approach to determine the optimal and safest route for BMW collection and transportation for such situation. The major objectives considered for route selection of vehicles, are the risk associated with the collection and transportation of BMW; total scheduling time of vehicles and number of vehicles. In this approach, clusters of the hospital nodes are constituted based on their distance from the nearest depot and late time window associated with the hospital node. Thereafter, the routes are scheduled and optimised using modified multi-objective ant colony system (MOACS). The computed results are validated abreast with benchmark solutions, demonstrating effectiveness of the proposed approach. Its applicability is elucidated using an illustrative example based on realistic data.","PeriodicalId":13984,"journal":{"name":"International Journal of Environmental Technology and Management","volume":"21 1","pages":"77-90"},"PeriodicalIF":0.6,"publicationDate":"2018-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45424675","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}

S1 and S2 isolate effectively decolorised all azodyes tested within 72 hours. These isolates were later characterised as Achromobacter and Bacillus sp. The resistance traits on plasmid were evidenced from curing experiments. Sodiumdodecyl sulphate (SDS) and rifampicin (9 mg/ml) was found to be most effective curing agent. Achromobacter sp. was positive for tryptophanase, indole and citrate permease with ability to ferment glucose and produced gas. While, S2 showed the presence of tryptophanase, but found negative for the urease. Both the isolates were able to sustain salt concentration between 4%-10% suggesting moderately halotolerant. Bacillus sp. exhibited tolerance to heavy metal, zinc and arsenic up to 8 M; copper, cobalt and nickel to an extent of 500 mM. Efficient decolorising activity, heavy metal and salt tolerance capability indicates that isolated strains can be utilised effectively for the treatment of effluents in the dye industries.","PeriodicalId":13984,"journal":{"name":"International Journal of Environmental Technology and Management","volume":"21 1","pages":"137"},"PeriodicalIF":0.6,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66766358","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 Environmental Performance Index (EPI) is used as an indicator of environmental quality. The results do not show an inverted U-shape relationship or the effect of the environmental Kuznets curve (EKC). Concerning the environmental performance, the GDP per capita and energy use have the most significant explanatory power on pollution for developing countries. The other economic determinants of pollution are trade openness, financial development, foreign direct investment, and urbanisation are of indirect influence because they are strongly correlated with economic growth and energy use. The obtained results show a positive and statistically significant relationship between economic performance and environmental quality, and empirically an increase in GDP per capita by USD 100 improves EPI in absolute value by 0.1. Energy use (kg of oil equivalent per capita) is statistically significant and negatively correlated with environmental performance. Thus, 100 kilograms of oil equivalent per capita reduces EPI in absolute value by 0.2. One of the policy implications of research is to stimulate economic development, while reducing oil consumption.","PeriodicalId":13984,"journal":{"name":"International Journal of Environmental Technology and Management","volume":"35 1","pages":"222"},"PeriodicalIF":0.6,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66766904","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}

Economic scarcity takes this and other aspects into consideration. The price spike in 2007/8 induced a scientific debate on a 'peak P' similar to the dispute on the oil peak back in the 1970s. The processing of phosphate rock to P fertilisers fed the Green Revolution and, therefore, was seen a chance to overcome the hunger on earth. Thus, the expansive use of P had serious negative impacts to the reserve stock of P. However, if and only if business sees a certain price margin as a threshold beyond P cannot be explored and marketed with benefit for agricultural use, in this particular case only P gets really a scarce resource. The peak price shock in P had almost other reasons than a real physical shortcoming in the reserve stocks. Moreover, if a certain price threshold would be exceeded and agriculture and industry still demand P, recycling technologies and better management practices are already at hand to supply enough P for sustaining food production. Additionally, a consequent recycling of P rich wastes and usage of P accumulated in soils and sediments cannot only set limits for P pricing but also revoke postulated P peak and P scarcity.","PeriodicalId":13984,"journal":{"name":"International Journal of Environmental Technology and Management","volume":"21 1","pages":"373-395"},"PeriodicalIF":0.6,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66767126","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}
