This study presents a life cycle assessment (LCA) of ten single family houses located in Eastern Slovakia with the aim to compare them in terms of the materials and technologies used. The main goal is to investigate and emphasize the reduction rate of environmental impact resulting from using green materials and technologies. Environmental impacts are determined by using eToolLCD software. Life cycle impact assessment (LCIA) categories of global warming, ozone depletion, acidification, eutrophication and photochemical ozone creation potential, as well as abiotic depletion potential - elements, abiotic depletion potential - fossil fuels, use of renewable primary energy resources, net use of fresh water, components for reuse and materials for recycling are determined within the cradle-to-grave boundary. Assessed family houses are built as a combination of conventional materials such as aerated concrete blocks, expanded polystyrene (EPS), extruded polystyrene (XPS) and roofing mineral wool and natural materials such as wood, cellulose, clay, straw and extensive vegetation roofs. Multi-criteria decision analysis points out that material optimization of building structures as well as the application of green technologies can ensure a considerable reduction of environmental impacts.

With the rapid development of industry in China, China has become the largest producer of refined copper as well as the largest consumer of copper in the world. In order to provide the support for decreasing the environmental impact of the copper pyrometallurgy of China, the life cycle assessment methodology was carried out in this study to identify and analyze the typical processes’ environmental load of refined copper production from ‘cradle-to-gate’ perspective. The results showed that the most serious environmental impact of copper pyrometallurgy was abiotic depletion potential and human toxicity. The abiotic depletion potential mainly comes from the copper ore mining, for this reason, increasing the use of renewable copper is an effective means to alleviate environmental load of our country copper pyrometallurgy industry. Meanwhile, reducing the direct and indirect discharge of poisonous and harmful elements (e.g. heavy metals) from the copper ore mining stage and the copper smelting process could decrease the human health damage efficiently.

The purpose of this study was to deduce the major construction wastes to be managed using environmental impact assessment for construction wastes generated in the construction phase. To accomplish this, the amount of construction waste discharged in the construction phase was analyzed using loss rate and weight conversion factor in the Standard of Estimate for Construction Works. Based on the result of construction waste generation deduced, major construction wastes were extracted with consideration on 6 comprehensive environmental impacts including potential, abiotic depletion potential, acidification potential, eutrophication potential, ozone depletion potential, and photochemical ozone creation potential. As a result, 5 major building materials such as concrete, concrete block, rebar, cement and polystyrene panel were deduced as major cpmstruction wastes in construction phase.

This paper includes a cradle-to-gate life cycle impact evaluation of gasoline blends in India. The potential environmental impacts of gasoline blends with three major components, i.e., methanol, ethanol, and n-butanol are assessed. The production of methanol from the natural gas reforming process, ethanol from hydrogenation with nitric acid, and n-butanol from the oxo process are considered in the current study. The results show that the gasoline blending with methanol has the lowest impact (11 categories) and is nearly constant from 5 to 15%. For gasoline with ethanol as an additive, the global warming potential, ozone depletion potential, and abiotic depletion potential rise with increasing ethanol addition. Meanwhile, increasing ethanol addition reduces the acidification potential and terrestric ecotoxicity potential impact of gasoline blends. Similarly, gasoline with n-butanol as an additive has higher acidification potential, eutrophication potential, human toxicity potential, terrestric ecotoxicity potential, marine aquatic ecotoxicity potential, and photochemical ozone creation potential compared to methanol and ethanol.

Including criticality into Life Cycle Assessment (LCA) has always been challenging to achieve but desirable to accomplish. In this article, we present a new approach for the evaluation of resource consumption of products by building comparison values based on Life Cycle Impact Assessment (LCIA) combined with weighted criticality values to show the direct impacts of criticality on LCA results. For this purpose, we develop an impact indicator based on the Abiotic Depletion Potential (ADP) of natural resources and use the two main parameters defined by the EU to determine the criticality of a material - the economic importance and the supply risk – in our case studies to build the Criticality Weighted Abiotic Depletion Potentials (CWADPs), one for each parameter. These indicators allow identifying and measuring the impacts of criticality when comparing the results of resource depletion using the ADP methodology and the results that incorporate criticality. The comparison of the CWADPs to the corresponding EU criticality values and its thresholds it reflects the equivalent criticality of the assessed product. This information reflects the impacts of criticality on LCA and assesses the total resource consumption of critical materials in a system.Keywords: Life Cycle Assessment, criticality, resources, materials, sustainability indicator

While resource aspects are gaining increasing importance for the sustainability assessment of new technologies, the question of how to assess the depletion of abiotic resources is still controversially discussed. Different methodologies exist for their quantification within life cycle assessment (LCA). Among them, thermodynamic approaches have the advantage of considering aspects of absolute quantity (reserves or amount of a substance contained in total in earth’s crust) and of quality (concentration of the target element in the mined resource), making them a potentially appealing approach for assessing resource depletion. However, existing approaches are either far from the original thermodynamic idea of exergy or far too complex and not applicable for resource accounting. This work briefly discusses the suitability of exergy-based approaches for resource assessment, and then suggests a simple but comprehensive methodology for quantifying resource depletion related with the concept of chemical concentration exergy (MDPces). It provides a calculation approach for quantifying the MDPces and estimates the corresponding values for some representative key metals.

Conserving the geological heritage in Jalisco implies, identifying, classifying and substantiating the importance of geosites in Jalisco and its subsequent dissemination through geotourism. The above can contribute to the creation of geo-park (s), according to the definition and methodology of UNESCO, with the consequent economic benefit to the inhabitants of these regions. The disclosure of geological information encourages an appreciation and care of abiotic resources (rocks, minerals, fossils, morphology, soil and water), especially prior to productive activities, minimizing their damage or avoiding building in areas with geological hazards. Jalisco has a great geodiversity, compared to other states, its history begins approximately 200 million years ago, recorded in the Sierra Madre del Sur and in the Jalisco Block, the most recent volcanic and tectonic activity is recorded in the Volcanic Belt Mexican. The previous provinces, together with the Sierra Madre Occidental and the Central Plateau, contain a wide range of rocks, fossil areas of economic and cultural importance (most of 70 places) and relate the geological history and its dynamics. Geothermal activity, is present in 400 locations.
