The Impact

Potential environmental benefits have been identified for the utilization of carbon dioxide (CO2) as a feedstock for polyurethanes (PUR). CO2 can be utilized in the PUR supply chain in a wide variety of ways ranging from direct CO2 utilization for polyols as a PUR precursor, to indirect CO2 utilization for basic chemicals in the PUR supply chain. In this paper, we present a systematic exploration and environmental evaluation of all direct and indirect CO2 utilization options for flexible and rigid PUR foams. The analysis is based on an LCA-based PUR supply chain optimization model using linear programming to identify PUR production with minimal environmental impacts. The direct utilization of CO2 for polyols allows for large specific impact reductions of up to 4 kg CO2-eq. and 2 kg oil-eq. per kg CO2 utilized, but the amounts of CO2 that can be utilized are limited to 0.30 kg CO2 per kg PUR. The amount of CO2 utilized can be increased to up to 1.7 kg CO2 per kg PUR by indirect CO2 utilization in the PUR supply chain. Indirect CO2 utilization requires hydrogen (H2). The environmental impacts of H2 production strongly affect the impact of indirect CO2 utilization in PUR. To achieve optimal environmental performance under the current fossil-based H2 generation, PUR production can only utilize much less CO2 than theoretically possible. Thus, utilizing as much CO2 in the PUR supply chain as possible is not always environmentally optimal. Clean H2 production is required to exploit the full CO2 utilization potential for environmental impact reduction in PUR production.

The Impact

Garbage incineration is an effective minimization and resource processing methods, but there are no comparative analysises about the environmental impact of incineration processes. To investigate the environmental impacts of three typical MSW incineration processes, we modeled scenarios, calculated energy consumed and six aspects which classified as GWP, ODP, AP, EP, POCP and DUST. The classification results showed the value of the environment impact potential respectively. The impact potential of heat recover-dry absorption processes according to normalized results in descending order is GWP>EP>DUST>AP>POCP>ODP, in contrast the rank of heat recover-wet absorption and semidry processes is GWP>EP>AP>DUST>POCP>ODP, global warming impacts is the most significant penitential factor. The rank of impact potential according to weight factor in descending order is GWP>EP>DUST>AP>ODP>POCP. Dust potential became more significant. The weight factor of Dust is almost twice as much as that of AP. This is because there is a large gap between baseline level and the target level, the solid-waste are the focus of control in these years. In environmental terms, the environmental depletion index of heat recover-dry absorption process is lowest with minimal environmental impact and the heat recover-wet absorption process is the highest with largest environmental impact. The incineration with dry absorption program is the best environment-friendly process in term of environmental impact. Utilization of waste water and reducing total amount of water entering the system can effectively reduce the environmental implication for both HW and HS processes.

The Impact

Water is supplied in the Greater Istanbul Metropolitan Area from the surface water of six main reservoirs. The present land use in the catchment areas of the reservoirs indicates that the area devoted to agricultural activities and to forests and meadows varies between 73 and 97% and that only a minor percentage, 1-26%, is devoted to settlements and industries. In contrast to the land use profile, the current environmental evaluation of the catchment areas reveals that point sources dominate over diffuse sources. However, this trend is expected to be reversed in the near future, making diffuse sources and control of fertilizers and pesticides the most significant issue. Pollutant loads regarding pesticides and fertilizers are calculated from unit loads based on area. These pollutants are observed to have a negative impact on water quality in terms of eutrophication and toxicity. In this paper, the status of fertilizers and pesticides are addressed and some protective measures for reducing the impact of agricultural pollutants in the reservoirs are recommended.

The Impact

Governments and environmental conservationists agree that wetland resources need to be utilized sustainably to ensure the continued presence of wetlands and their ecological goods and services. Ideally, wetlands should be integrated into the national and local land use plans to ensure sustainable use and management of the resources. However, this is not the case as far as Kenya is concerned. Instead, there is rampant exploitation of wetlands by individuals, organizations and even government agencies with no regard to environmental conservation. Therefore, this study was undertaken to investigate the impact of human activities on wetland conservation with a focus on the Sondu River Basin. The objective of the study was to establish the effects of human settlements on the conservation of the Sondu River Basin. The study was grounded on the integrated water resource management theory. This study adopted a concurrent triangulation research design which entailed a combination of both qualitative and quantitative data. The target population for the study was 164 respondents in which a sample of 144 respondents was selected using Slovin’s formula. The sample was randomly selected with the inclusion criterion being that the chosen respondents were homogeneously engaged in human activities that affected wetland conservation. Intensive data cleaning exercise was carried out including checking for outliers, missing data imputation and variable transformation. The collected data were analysed by use of descriptive statistics such as frequencies, percentages and summation and presented in the form of tables and charts. The results of the study will inform policy and practice in the management and conservation of the Sondu River wetland area. The study established that human activities such as farming, logging, construction, drilling, building and construction and settlements have immensely hampered conservation of Sondu wetland. Further, it was noted that it is indeed possible to gain vital information about the human activities responsible for the degradation of wetlands.

Sustainable building management is a complex problem which needs effective, adequate and suitable assessment tools and methods to address issues of incommensurability and complexity, always considering the prevailing environmental policies and legislation. Within the frame of this paper, green certifications building schemes have been described, compared to each other and evaluated, against the background of the standards provided by the International Organization for Standardization. Emphasis have been placed on information referring to construction materials environmental evaluation based on the Life Cycle Analysis methodology and the role of construction materials selection to green building certification schemes. Finally, the impact of green certification schemes on the construction market, mainly as a tool of energy management, has also been examined in relation to the absence of mandatory international standardization in sustainable building management.

Within the commitments of the 2030 Agenda, the socio-economic objectives for a sustainable development of society as a whole, stand out, which propose minimizing the impact produced by all the activities of the Public Administration on the environment. Therefore, the creation and retrofitting of its infrastructures, needed for its operation and the services it provides, has a great impact. The goal of this work focuses on a methodological adaptation for the environmental evaluation of the works promoted by public organizations, quantifying and locating the sources of impact with the purpose of taking the measures to minimize them. For this, the footprint family, ecological, carbon, and water, are proposed as indicators, characterized by the simplicity of their message and the ease of their implementation in the construction sector, by controlling project costs. A case study is presented, the construction of an early childhood education center in the city of Madrid, for which the data needed for the calculation are presented and analyzed. The results reflect interesting information in terms of footprints, on the elements that must be controlled and improved in the project design, such as concrete and steel.

The interaction of architectural, urban planning activities and the natural environment is manifested at all hierarchical levels and its results need to be foreseen. The role of strategic environmental assessment is closely related to the concept of sustainability, since it is a tool that identifies the environmental impact of plans and programs implemented in the territory. The study examines the role of strategic environmental assessment in achieving sustainability of plans and programs at the international level, and concentrates on the problems of strategic environmental planning in Iraq. Strategic environmental assessment is a comprehensive process for assessing the impact of plans and programs on the environment. The previous studies have shown the effectiveness of using methods of strategic environmental assessment in promoting the comprehensive development of the territory; the ability of the public to participate in the assessment of environmental and social aspects of policies, plans, and programs. The purpose of the strategic environmental assessment (SEA) is to eliminate disproportions in the development of territories. A comparison of SEA and environmental impact assessment (EIA) has been carried out. In Iraq, strategic environmental assessment has been found to be a relatively new phenomenon. Its use in strategic planning of the territory will contribute to increasing the sustainability of development in Iraq, its application will be efficient in the country and its regions, and will ensure public participation in this process.
