Drinking water treatment reduces or eliminates certain health risks and ensures appropriate water quality by removing physical, chemical, and biological pollutants. The treatment process’s increased need for energy, chemicals, and technological inputs raises the expense of producing water as well as its secondary environmental effects. The goal of this research is to use the water quality index (WQI) and life cycle assessment (LCA) to determine and assess the environmental effects of the Al-Hashimiyah water treatment plant (WTP) in Babylon City, Iraq. The water quality index was employed as a criterion for categorizing and treating water in accordance with fundamental water characterization variables using a weighted arithmetic index technique. The LCA was supported by the EcoIndicator 99 database and SimaPro 7.0 software. What makes this study unusual is the identification of two extra functional units related to decontamination, beyond the usual one cubic meter treated water. Samples of treated and raw water were gathered during a 25-month period, from March 2022 to March 2023, and were regularly tested. The results demonstrated that all chemical and physical characteristics (for both raw and processed water) met Iraqi criteria, with the exception of total suspended particles and electrical conductivity. According to LCA studies, certain environmental consequences grow as pollutant concentrations drop. Due to this, a more thorough analysis of the environmental performance of water treatment facilities is now required.

The transformation of the automotive industry towards electromobility is a key step in achieving a sustainable transportation system. To analyze the economic feasibility of electric vehicles (EVs) compared to internal combustion engine vehicles (ICEs), this study assessed the operating costs of both types of vehicles, including fueling and charging costs on a selected theoretical route. The analysis of economic aspects also examined the development of fueling and charging infrastructure and the impact of government programs promoting electromobility. The study employs a comparative analysis of ICE and EV based on fuel and electricity prices, insurance costs, and servicing expenses. The results of the analysis indicate that adopting EVs can lead to significant economic benefits, especially when coupled with government incentives and well-developed charging infrastructure. The network of charging stations and fuel infrastructure serves as an indicator of the market conditions for vehicles equipped with either internal combustion engines or electric powertrains, and forecasts help anticipate their future directions. The decreased pace of new petrol stations being established may indicate a weakening market for internal combustion engine vehicles compared to previous periods. This study highlights the economic aspects of electromobility strategies aimed at accelerating the transition towards a sustainable transportation system.

Dynamically identifying key product changes is a challenge for enterprises. It is even more complicated if companies strive for the sustainable development of their activities. Therefore, the aim of the article was to develop a method to help predict the direction of product improvement, taking into account its quality level and environmental impact during the life cycle (LCA). The method was based on the design phase of LCA and the process of obtaining and processing customer expectations. Techniques supporting the developed method were: a questionnaire, a seven-point Likert scale, a standardised list of criteria for assessing the product life cycle, the WSM method, and a scale of relative states. The product analysis was carried out according to modified criteria states, which were evaluated according to: i) customer satisfaction (quality criteria), ii) environmental impact of LCA (environmental criteria), and iii) importance of quality and environmental criteria for customers. The originality of the method is to support the product improvement process to make it environmentally friendly within LCA and, at the same time, satisfactory to customers in terms of quality. The method will be used mainly by SMEs that want to initially predict the environmental impact of a product, including taking into account customer expectations.

The article pertains to two elements in the architecture of a single-family house that impact the ecosystem: the use of building materials and energy consumption. The issue is considered within the framework of analyzing material and energy changes affecting the natural environment. In the research, various methods were employed, including the concept of the 'shade mechanism' as a limit for the ecological footprint, as well as the Life Cycle Assessment (LCA) method. Three types of solutions were examined: the materials used in the building structure and their energy demands. The research results presented were analyzed with regard to the relationship between building materials, energy consumption, and their negative emissions (potential greenhouse effect). The objectives of the analyses were determined with regard to the changing climate and the possibilities of controlling pollutant emissions, taking into account the ability to minimize and control the adverse environmental impact as well as its enhancement and regeneration in the architectural design process.

This research aims to design recommendations for improving the tofu production process in Sugihmanik Village. Over 30 tofu small medium enterprises (SMEs) generate solid and liquid waste, which pollutes the river. An eco-efficiency strategy was implemented and began by identifying the tofu production process. The life cycle assessment (LCA) method and the SimaPro software were used to calculate eco-cost and eco-efficiency levels. Based on the calculations, the eco-cost value per batch is USD 10.76. If 30 batches are produced daily, the eco-cost value in one of the tofu SMEs is USD 9.10. Tofu production has an eco-efficiency index (EEI) value of 0.12. This value shows that tofu products are only affordable but have yet to be sustainable. The researchers then recommend using biogas from wastewater treatment to replace rice husks and corncobs. This study also develops a circular economy framework in the tofu production system. The output is expected to suppress the discharge of water and solid waste to increase the EEI value of the tofu production process in the future.

Closed-loop economy initiatives in Europe are still at an early stage. Progress in its implementation in industrial sectors, however, requires clarifying the concept from the perspective of balancing aspects covering environmental, economic and social issues, which may support the transformation process. Green polymer materials made from (bio)degradable, renewable, or recycled raw materials can help prevent and partially reduce waste and contribute to more sustainable life cycles. Furthermore, such materials could have a lower carbon footprint and, in some cases, may exhibit more favourable material properties in many applications. The article is an attempt to show that a systematic, standardised approach to quantifying the potential impacts of a product or process that takes from resource extraction to the end of a product life, such as life cycle assessment, can be an effective methodology for implementing sustainability in the circular economy.

Postęp w jej wdrażaniu w sektorach przemysłowych wymaga jednak wyjaśnienia tej koncepcji z perspektywy równoważenia aspektów obejmujących kwestie środowiskowe, ekonomiczne i społeczne, co może wspomóc proces transformacji. „Zielone” materiały polimerowe pochodzące z surowców (bio)degradowalnych, odnawialnych lub pochodzących z recyklingu mogą pomóc w zapobieganiu powstawania odpadów i częściowemu ich ograniczeniu oraz przyczynić się do bardziej zrównoważonych cykli życia. Ponadto takie materiały mogą mieć mniejszy ślad węglowy i w niektórych przypadkach mogą wykazywać korzystniejsze właściwości w wielu zastosowaniach. Celem artykuł jest wykazanie, że systematyczne, ustandaryzowane podejście do kwantyfikacji potencjalnych wpływów tych procesów począwszy od pozyskania surowców do utylizacji produktu, takie jak ocena cyklu życia, może być skuteczną metodologią wdrażania zrównoważonego rozwoju w gospodarce o obiegu zamkniętym.

Solid waste management is a significant environmental issue for countries because of the need for huge landfills. The ceramic tile waste powder (CWP) is one of the wastes. Conversely, cement production, the main ingredient in concrete, emits large quantities of greenhouse gases, a significant environmental concern. Therefore, substituting some of the cement in concrete with CWP is an issue that deserves investigation to reduce the environmental impact of both materials. Accordingly, this study aims to investigate the influence of the grinding time and proportion of CWP as a substitute for cement on the properties of high-strength mortar (HSM). Three grinding times (10, 15, and 20 minutes) and three replacement percentages (10%, 20%, and 30% by weight) for CWP were adopted for each time. Ten mixtures (including the reference mixture) were executed. The fresh (flow rate), mechanical (compressive strength) durability (ultrasonic pulse velocity, dynamic elastic modulus, water absorption, density, percentage of voids and electrical resistivity) and microstructural properties were examined. The life cycle assessment (LCA) was also addressed. The results showed that the mechanical activation had a pronounced effect on the durability properties (especially water absorption and percentage of voids) more than on the compressive strength. Generally, a sustainable HSM (with more than 70 MPa of compressive strength) can be produced in which 30% of the cement was replaced with CWP with almost comparable performance to the CWP-free mortar. Furthermore, LCA results showed that mortars containing 30% CWP ground for 15 mins (GT15CWP30) had the lowest GWP per MPa.

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.

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.

Traditional markets in Malang Regency are divided into four classes with particular classifications. The traditional market solid waste research aims to show the environmental impact of solid waste management efforts using life cycle assessment (LCA) and selected scenarios to reduce solid waste sustainably. The planned management follows four scenarios: Scenario 0 represents the baseline scenario. Scenario 1 assumes that non-composted solid waste recycling is carried out. Scenario 2 assumes that composting takes place. Finally, Scenario 3 assumes that non-composted solid waste recycling and composting are integrative ely carried out by building a reduced reuse recycle solid waste treatment facility (TPS 3R) near the market. The environmental impact analysis was carried out with various impact categories (carcinogens, respiratory organics, respiratory inorganics, climate change, radiation, ozone layer, ecotoxicity, acidification/eutrophication, land use, minerals, and fossil fuels). The results show that the smallest environmental impact is in Scenario 3 in most classes, namely the scenario where non-composted solid waste was integrative ely recycled and composted.

Solar photovoltaics systems (PV) deliver substantial benefits to the environmental when compared with the conventional energy sources, hence supporting to the human activities ecological benefits with sustainable development. To maintain the quality of the environment at the same time, technological innovations are very much essential to cater the needs of more electrical power according to the demand, decreasing carbon emission by replacing the carbon releasing fossil fuels with the renewable energy. Installation of such facilities require lakhs acres of land globally and thus leads to number of various ecological issues. This paper presents the insight to various environmental issues. Some of the issues are with respect to land, health of human beings, animals, plant lives and environment are presented in this paper. In terms of numbers, the area of land required for a PV system is less or same per kWh power generated, when compared with a thermal power station. Deforestation for installation of solar PV systems is one of the major drawback as it leads to enormous environmental impacts. This paper analyses effects on the environment due to the usage of solar PV systems like, at the time of construction, installation and also at the time of destruction, sound and visual incursions, air, water and soil pollution, emission of greenhouse gases, effects on archaeological sites accidents to unskilled labor, and various socio-economic impacts. Subsequently, reduction in greenhouse effect, carbon footprints, global warming, ozone layer depletion, climate change and acid rains are some of the positive impacts during transition to green energy, i.e., usage of fuels from fossil fuels to solar energy at regional level, national level and global level. This paper outlines the pros and cons, positive and negative environmental impacts, by using solar PV systems to generate electrical power.
