The Federal Aviation Administration (FAA) has taken measures to improve safety, reduce costs, increase resilience, and improve the sustainability of the United States (U.S.) airfield infrastructure by using a life-cycle cost analysis methodology to increase the efficient use of economic resources needed for expanding and preserving the airfield system. However, a life-cycle assessment (LCA) approach for evaluating the environmental impacts of decisions regarding airfield infrastructure has yet to be fully developed and applied. The objective of this study is to demonstrate the use of the airfield LCA framework that was developed for the FAA and can be used by U.S. airports. The comparison of alternative pavement designs at Nashville International Airport (BNA) is presented. The scope of the study was from cradle to laid; materials, materials transportation, and construction stages of the pavement life cycle are considered, and the maintenance, use and end of life stages are not considered. Primary data were acquired from BNA and secondary data were used in situations of unavailability of primary data. The case study showed that performing LCA provides opportunities for airports to consider energy use and environment-related impacts in the decision-making process.

In industrialized countries, packaging waste is one of the major issues to deal with, representing around 35% of the total municipal solid waste yearly generated. Therefore, an analysis and an environmental assessment of packaging systems are necessary. This paper aims at analyzing and comparing the environmental performances of two different packaging for domestic hoods. It shows how, through a packaging redesign, it is possible to obtain a reduction of the environmental impacts. This study has been performed in accordance with the international standards ISO 14040/14044, by using attributional Life Cycle Assessment (LCA) from Cradle to Gate. The functional unit has been defined as the packaging of a single household hood. Primary data have been provided by a household hood manufacturer, while secondary data have been obtained from the Ecoinvent database. LCA software SimaPro 8.5 has been used to carry out the life cycle assessment, and ReCiPe method has been chosen for the life cycle impact assessment (LCIA) stage. The results have shown the new packaging model being able to cut down the environmental impacts of approximately 30%. These outcomes may be used by household manufacturers to improve performances and design solutions of their different packaging.

PT Adaro Indonesia is trying to adjust a vertical clearance under Tabalong Bridge 1 (unloaded) and Tabalong Bridge 2 (loaded) because the existing conditions still apply a minimum vertical clearance of 4 m. I t should be in accordance with latest Regulation of the Minister of Public Works No. 19/PRT/M/2011 that for vertical clearance above national road at least 5.1 m. This specification has not been met by the national road under the Tabalong 1 & 2 Bridges bec ause both bridges were built in the 90s. Therefore we need an engineering technique to overcome this. There are 2 alternative designs, namely lowering the elevation of the national road and increasing the elevation of the bridge's upper structure to mitiga te oversized vehicles so as not to hit the lower structure of the Tabalong bridge. In determining the selection of the best alternative designs in this research is based on two (2) things, non financial criteria with Analytical Hierarchy Process (AHP) and financial criteria with Life Cycle Cost Analysis (LCCA)/Benefit Cost Ratio (BCR) method. This study uses a survey method by distributing questionnaires and interviews as a means of collecting primary data. In addition, previous research and consultant DED documents were used as a means of collecting secondary data. The AHP method is used to process primary data to produce a decision from a non financial aspect. While the LCC/BCR method is used to process secondary data to produce a decision from the financi al aspect . The results of the AHP analysis obtained that the synthesis value of the decision the option of lowering national roads was 85% and the bridge lifting option was 15% and the consistency ratio (CR) was 0.05 < 0.1. The consistency ratio below 0.1 shows that the questionnaire data from the respondents are consistent. The results of the analysis of Life Cycle Cost (LCC) obtained the option of lowering national roads where the LCC value is Rp. 44,877,651,669.27 more economical than the bridge lifting option. Then the results of the Benefit Cost Ratio (BCR) analysis obtained the option of lowering national roads with a BCR value of 2.33 > 1 and NPV = Rp. 43,442,264,804.34 > 1 means that the option lowering national roads is feasible. While the bridge li fting option is obtained by analyzing the value of BCR = 0.98 < 1 and NPV = option is not feasible to implement.

This paper introduces the need for the responsible selection of construction products and then analyses a number of assessment methodologies. Some computer packages and guidebooks that assist in life cycle assessment or aid construction product selection are briefly reviewed. Issues that affect decision-making and complexities in the construction industry are discussed. A tool for assisting responsible construction product selection is then presented that involves carrying out a streamlined life cycle assessment, comparing a novel product to a traditional product. The tool is pragmatic because only three environmental criteria are considered (resource consumption, energy use and human and ecological impacts) and a relative rather then absolute assessment is required. The decision-assisting methodology is demonstrated with a case study. The limitations and benefits of the streamlined LCA are finally presented.

Development of the pavement network systems, which is inevitable due to the rapid economic growth, has increasingly become a topic of significant concern because of the severe environmental impacts of road expansion. For achieving the sustainable development goals (SDGs), the policies and actions towards the pavements’ life cycle assessment (LCA) and life cycle cost analysis (LCCA) must be carefully assessed. Consequently, the purpose of this review is to present an overview of LCA and LCCA used in pavement engineering and management. Through the quality control of PRISMA, fifty-five most relevant documents were extracted for a thorough investigation. The state of the art review reveals that a limited number of the papers considered environmental impacts of the pavements. Consequently, to assess the environmental impact cost, a conceptual framework was developed to better consider the LCA and LCCA on various aspects of the pavement projects including the sustainability aspects. Besides, a case study was given to validate the literature review towards proposing a novel framework for the incorporation of environmental impact cost.

Maritime security still focuses on the territorial sovereignty of a country. Environmental disasters and transboundary humanitarian crimes that occur at sea are a challenge for International Relations academics to reformulate maritime security. British Petroleum (BP) is negligent in implementing safety standards in oil exploration and exploitation in the Gulf of Mexico, United States resulting in oil leakage on the Deepwater Horizon platform. This research uses the Deepwater Horizon case study in exploring the relevance of maritime security in the prevention and management of marine pollution disasters. Primary data sources were taken from observations of researchers in seminars related to the Deepwater Horizon and secondary data were obtained from journals, electronic news and official reports from the US Government. There are two findings obtained. First, contemporary maritime security is much more complex than traditional maritime security and second, contemporary maritime security involves an element of justice seeking as demonstrated by the United States Court's decision against BP regarding negligence in the Deepwater Horizon.   Keywords: Maritime Security, United States of America, Deepwater Horizon, British Petroleum
