Opis:
Purpose: The purpose of this article is to present the results of an analysis of the environmental impact of an innovative vertical parking solution, the so-called smart parking lot. Design/methodology/approach: The Life Cycle Assessment (LCA) method was used for the analysis. The study was conducted in accordance with the recommendations of ISO 14040/44. Calculations were carried out using SimaPro software and the Ecoinvent database. Findings: The analysis identified significant issues in the life cycle of a smart parking lot, i.e., parameters indicating the greatest potential environmental impact of the solution, in categories such as climate change, ozone depletion, carcinogenesis, eutrophication, acidification, use of mineral and metal resources, and fossil fuels. Practical implications: The results presented can be taken into account at the stage of developing eco-innovative technical solutions. Originality/value: The problem of an insufficient number of parking spaces forces the search for optimal urban, economic and environmental solutions for the construction of parking lots. Research results presented in the article represent the first phase of a broader project on the analysis of the environmental impact of selected parking solutions.

Opis:
The production of cocoa beans in Indonesia into chocolate and other cocoa-derived products produces emissions that pollute the environment. This research aimed to calculate the carbon footprint of the cocoa agroindustry using the Life Cycle Assessment approach in Lampung, Indonesia. The LCA under study is within the scope of Cradle to Grave, starting from nurseries_cocoa plantations_dry cocoa beans_chocolate production_retail, and consumers with emission function units per 1 kg of product. The method refers to the ISO 14040:2006 life cycle assessment standard, with the stages of determining objectives and scope, inventory analysis, impact assessment, and interpretation of recommendations. Primary data was analyzed using Simapro 9.4.0.2 Software. Secondary data was collected through a literature study. Data analysis shows the highest environmental impact after normalization resulting from four activities: packaging, transportation from industry to marketing office, and transportation from marketing office to retail. The highest environmental impact is generated by industrial activities, with a total emission of 2.57E-10 per kg of dark chocolate. In this study, GWP 100a emissions from cocoa agroforestry and agroindustry activities within the scope of the Cradle to Grave study were 7.31E+01 kg CO2-eq per kg dark chocolate. In addition, selecting the type of packaging is an indicator that must be considered. Using a combination of aluminum foil, paper, and cardboard as packaging causes the second highest emission in the packaging sub-process after transportation from industry to marketing office in industrial activities. It is the 4th highest of all activities. One of the reasons for the high emissions produced in the final product or cocoa consumed by consumers is no longer in doubt. On the basis of normalization activities, the highest environmental impacts were generated by industrial activities, with a total emission of 2.57E-10. The use of packaging in packaging and fuel activities in transportation from industry to marketing office activities, industrial activities also use quite a large amount of electrical energy, namely 421.91 kWh. Recommendations for improvement can be identified to reduce the GHG impact and increase energy efficiency. Energy-saving sustainablemethods constitute a challenge for the cocoa agroindustry because they positively impact the reduction of the global warming potential.

Opis:
This paper attempts to conduct a comparative life cycle environmental analysis of alternative versions of a product that was manufactured with the use of additive technologies. The aim of the paper was to compare the environmental assessment of an additive-manufactured product using two approaches: a traditional one, based on the use of SimaPro software, and the authors’ own concept of a newly developed artificial intelligence (AI) based approach. The structure of the product was identical and the research experiments consisted in changing the materials used in additive manufacturing (from polylactic acid (PLA) to acrylonitrile butadiene styrene (ABS)). The effects of these changes on the environmental factors were observed and a direct comparison of the effects in the different factors was made. SimaPro software with implemented databases was used for the analysis. Missing information on the environmental impact of additive manufacturing of PLA and ABS parts was taken from the literature for the purpose of the study. The novelty of the work lies in the results of a developing concurrent approach based on AI. The results showed that the artificial intelligence approach can be an effective way to analyze life cycle assessment (LCA) even in such complex cases as a 3D printed medical exoskeleton. This approach, which is becoming increasingly useful as the complexity of manufactured products increases, will be developed in future studies.

Opis:
Recycled aggregate brick (RAB) constitutes a significant waste stream in developed countries, originating from brick manufacturing and demolition processes. This paper investigates the potential utilization of various sizes of RAB as replacements for natural aggregate (NA) in cement-treated bases (CTB), along with an assessment of their mechanical and environmental properties. The study includes a life cycle analysis to evaluate the environmental impacts of different CTB formulations. The novelty of this study lies in the environmental evaluation of four types of CTB, including natural, recycled, and mixed CTB. The physical and mechanical properties of the recycled brick and natural materials are characterized and compared. Results indicate that recycled brick aggregates, when combined with a cement mixture, can be used as a base and sub-base layer with good mechanical performance. Moreover, environmental analyses demonstrate that recycled aggregate generates fewer impacts than natural aggregates. Consequently, this study suggests that the utilization of recycled aggregates brick in CTB offers a sustainable waste management solution while simultaneously contributing to the reduction of environmental impacts associated with construction activities.

Opis:
Pesticides are at risk due to their toxic properties in humans as well as impact on the environment and ecosystems. Indonesia has 1,336 formulations and 402 pesticide ingredients registered to control pests in various commodity fields. The negative effects of synthetic chemical pesticides are resistance, resurgence, second pest blasting, and environmental degradation. Pesticide residues on the soil and agricultural products can cause bioaccumulation and biomagnification processes. The biomagnification process can cause exposure to pesticides that enter the human body to a greater degree than the residues found in the environment. Therefore, it is necessary to research the life cycle analysis of exposure and pesticide residues in agricultural environments. This study is an observational study with a cross-sectional design. The sample in this study was 120 respondents. This research was conducted in the Wanasari subdistrict, Brebes regency. Wanasari subdistrict is the largest shallot-producing centre in Brebes regency (26%). The shallot harvest area in Wanasari district is 6,598 ha. The life cycle analysis (LCA) results of shallot farming include five stages: soil maturation, planting seedlings, fertilizing, applying pesticides, and harvesting. The emissions in shallot farming activities come from diesel fuel, pesticides, and NPK fertilizers. Chlorpyrifos pesticide residues were found with an average level of 0.6451 ppm in 9 villages in Wanasari district.

Opis:
Research background: The increasing water demand together with an unceasing production of wastewater worldwide has resulted in a situation where the scarcity and pollution of water resources are jeopardizing and depleting such a vital asset. Purpose of the article: In this context, Nature Based Solutions (NBS) such as Vertical Flow Constructed Wetlands (VFCWs) are key because of their capacity of channelling a waste into a resource. However, and notwithstanding their essential role, their financial benefits too often go unnoticed because of missing research that study them from an economic perspective and this article has covered this existing gap. The objective of this research is to analyse the economic consequences of using VFCW against its traditional alternative through a comprehensive economic assessment. Methods: After doing a Life Cycle Assessment (LCA), a combination of two approaches has been carried out. This research has developed a holistic approach where a Life Cycle Cost Assessment (LCCA) based on a Cost Benefit Analysis (CBA) along with an economic evaluation of cleaning environmental costs have been calculated for two different scenarios. For this monetary analysis, the environmental externalities derived from the use of cleaning the pollution caused by a public water supply and sewerage system and the VFCW have been quantified. Findings & value added: Results conclude that VFCW apart of being a cost-effective and profitable alternative for an investor, it has also valuable benefits for the society in general because of its meaningful and positive externalities and the high removal cost of the environmental pollutants of the traditional water supply and sewage system both contributing directly to the achievement of Sustainable Development Goals (SDGs). Furthermore, 4/5 environmental impacts derived from the use of traditional alternative pollute more than twice as much as the VFCW does. Lastly, the cleaning costs difference between both alternatives is 1,984,335€.

Opis:
This study uses TruckSim™ to model disc brakes and drum brakes on a fully loaded truck semi-trailer to study the performance of each brake type as downgrades and speeds vary. The brake performance is measured based on braking distance. A simplified economic comparison based on life cycle cost analysis to determine which road and vehicle conditions give rise to the cost-effectiveness of disc brakes is performed. The studies suggest that disc brakes shorten braking distances by 10-20%. They also suggest that the percentage reduction in braking distance as speed increases and downgrade gets steeper is approximately 12-19%. Evidence is provided that trucking companies operating their vehicles in steep terrain and at high speeds with disc brakes could benefit from 12-80% in long-term cost savings. Finally, at the societal level, by preventing crashes arising from rear-end collisions and runaway truck incidents, disc brakes save at least $649 million annually.

Retrofitting heating, ventilation, and air conditioning (HVAC) systems in existing buildings and applying energy-efficient technologies can significantly reduce energy consumption and greenhouse gases emissions. In this work, two options of HVAC retrofitting were proposed and discussed for the existing heating system of school of engineering at the University of Jordan as a case study. The experimental tests showed that only one of the three diesel boilers work normally while the other two boilers are not efficient, with actual efficiency of 25%. The first retrofitting was to upgrade the existing heating system to a liquefied petroleum gas (LPG) boiler system with estimated annual saving of 29,757 Jordanian dinar (JOD), and a payback period of 3.9 years. The second option for retrofitting was a new HVAC system for the building including heating and air conditioning with a variable refrigerant flow (VRF) system and heat pump chiller. The estimated cost showed that the VRF system was the lowest one in running cost in winter. The diesel boilers had the highest greenhouse gas emissions with an average value of 377.3 tons of CO2 per year, while LPG boilers achieved the second highest emissions of around 279 tons of CO2 per year, whereas the heat pump chiller in winter produced 199 tons of CO2 and the VRF system emitted 180 tons in winter. The LCCA economic analysis was performed for the proposed systems, showing that the LPG boilers system was more feasible than the diesel boilers system, while the VRF system was more feasible than the heat pump chiller system.

Opis:
The increasing importance of environmental protection issues has recently forced a low–emission approach to investment processes. To accomplish the European Union's climate, energy and environmental goals, action is needed to achieve high levels of energy efficiency and low environmental damage. Among the energy–intensive sectors, construction deserves a distinction due to its leading share in gross energy consumption in developed countries. Therefore, it is necessary, and at the same time more and more popular, to analyse the environmental loads generated in individual phases and throughout the life cycle of building objects. This subject is also gaining importance in the context of the recent increases in the prices of energy carriers, which forces the search for new construction and exploitation solutions in line with the philosophy of sustainable development and the circular economy. The aim of the analysis was to assess the environmental consequences in the life cycle of a real commercial building located in Janikowo (Kuyavian–Pomeranian Voivodeship), which was carried out using the LCA (Life Cycle Assessment) methodology. The obtained results indicated the dominance of the facility exploitation phase in the level of cumulative environmental loads.

Opis:
This paper deals with an analysis of causes that lead to the change in price (value of construction costs) of road infrastructure projects in selected phases of the building structure life-cycle, more specifically procurement and construction phases, with the aim to refine the price estimation in the Estimated Value determination phase. The sample of regional road construction projects in the South Moravian Region (Czech Republic) documentation forms the basis for the research. The methodological procedure is aimed at monitoring changes in the value of construction costs during the preparation and implementation phase of the construction. Estimated values, contract prices and actual prices of individual projects are compared to determine them and the reasons for their differences are discussed. The changes (decrease) in the values of construction costs determined by estimated value and contract price show the strong influence of the construction market and the interest of construction companies in the implementation of public works contracts in the field of road infrastructure projects. The relative differences range up to 47%. The changes (increase) in construction costs determined by contract price and actual price are much lower, up to 13%, and result from specific situations during the implementation of the construction, for which subsoil bearing capacity problems and material changes were determined as the most significant.

Opis:
Due to the minimal transfer of heat from absorber plate to moving air in the duct, solar air heaters have low performance. One of the procedures to augment the heat transfer by substantial amount is by utilizing artificial roughness, by which the performance can be improved considerably. In this study, an economic investigation of solar air heater embedded with artificial roughness is accomplished numerically employing v-shaped roughness, with the objective of optimising life cycle solar savings. The non-dimensional parameters of roughness, namely, angle of attack (α), roughness pitch (p/e) and roughness height (e/Dh) are examined by varying temperature rise over the solar air heater (∆T) and solar radiations (I) for different economic parameters values i.e., cost of collector, cost of roughness elements, and cost of conventional fuel.

Opis:
We analyse tenure choice determinants of Poles for the years 2006, 2010, 2014 and 2018 on EU-SILC data, distinguishing between co-residence with the parents, renting at market rates and owning a house. The average marginal effects obtained from multinomial logistic regressions allows us to conclude that ownership is strongly connected to the family status, but this relationship weakens over time. Unmarried people without children but with better incomes become increasingly more likely to be homeowners. Thus, ownership is not anymore a main domain of conventional families. Moreover, renting becomes an option to become independent for those who cannot afford to buy a house. But it is rather a temporary solution, because renting is more costly than buying a house with a mortgage. We also find evidence of the gender gap in homeownership, as women are more likely to be owners, and less likely to co-reside with their parents than men. Along the evolution of the housing finance system, growing wages make ownership more likely. We observe that the choices are more free in densely populated regions, where the rental market develops. In this part of the paper explain the data that we use, present the empirical results and discuss them.
Zostały przeanalizowane determinanty wyboru struktury własności przez Polaków w latach 2006, 2010, 2014 i 2018 na podstawie danych EU-SILC, przy rozróżnieniu na współzamieszkiwanie z rodzicami, wynajem po stawkach rynkowych i posiadanie domu na własność. Średnie efekty krańcowe, uzyskane na podstawie wielomianowych regresji logistycznych, pozwalają stwierdzić, że posiadanie domu jest silnie związane ze statusem rodzinnym, ale związek ten z czasem słabnie. Osoby stanu wolnego, nieposiadające dzieci, ale o lepszych dochodach, stają się coraz bardziej skłonne do posiadania domu. Tym samym własność przestaje być główną domeną rodzin konwencjonalnych. Co więcej, wynajem staje się opcją usamodzielnienia się dla tych, których nie stać na kupno domu. Jest to jednak raczej rozwiązanie tymczasowe, ponieważ wynajem jest droższy niż zakup domu z kredytem hipotecznym. Autorzy znajdują również dowody na istnienie różnic w zakresie własności domów pod względem płci posiadaczy – kobiety częściej niż mężczyźni są właścicielkami, a rzadziej współmieszkańczyniami swoich rodziców. Wraz z ewolucją systemu finansowania budownictwa mieszkaniowego rosnące płace zwiększają prawdopodobieństwo posiadania domu. Zaobserwowano, że w regionach gęsto zaludnionych, gdzie rozwija się rynek najmu, wybory są bardziej swobodne. Objaśniono wykorzystane dane, zaprezentowano wyniki empiryczne i poddano je dyskusji.

Opis:
In pursuance of the Saudi vision 2030, the Al-Hasa municipality has been allocating a total of US$ 60.1 million since 2018 to the implementation of a modern Municipal Solid Wastes (MSW) management system. In addition to the improved old components, the system involves six new-engineered cells, five of which will be gradually implemented in progresses, two waste sort-out lines station, and LFG energy recovery. The present research aimed at investigating the environmental and economic impacts of this MSW management system. For this purpose, the authors applied the Life Cycle Analysis (LCA) and Life Cycle Costs Analysis (LCCA) approaches. The main results showed that the air quality was not affected. For instance, gas emission, like carbon monoxide, was less than 0.1 ppm. However, soil and groundwater were contaminated due to leachate infiltration from the uncontrolled cell in which Chloride, Nitrate, and Sulfate exceeded the maximum limits. As for noise, it was found to be high near the sorting-out station at 71.1 Leq dBA. In terms of the financial aspect, the improved MSW management was relatively feasible despite its high costs over its revenues. Thus, the negative cash-flow could be supplemented by setting household taxes at US$ 29 per capita per year, which makes the project cost-effective. Thus, the research recommends continuing the MSW management project.
