However, these benefits are context-specific, requiring precise studies for optimal solutions. This paper presents the life-cycle environmental performance of an innovative prefabricated interior partition wall and benchmarks it against a conventional system, providing a replicable model for other novel partition walls. Detailed data collected directly from direct sources were utilized to conduct a cradle-to-gate with options Life Cycle Assessment (LCA), presenting a conveniently described method that can be widely replicated in the construction sector. The adapted LCA method presented in this study contributes to sustainable construction, providing a straightforward and robust approach to assessing the environmental impacts of innovative partition walls compared to conventional walls. For the specific scenario studied, the life-cycle impact assessment results generally indicate a superior environmental performance of the innovative prefabricated interior partition wall compared to the conventional system, resulting in impact reductions ranging from 10 to 60% across evaluated categories. For both systems, the production of materials plays a predominant role in the impact contributions. Furthermore, exploring alternative scenarios yielded significant environmental benefits, particularly in cases considering higher incorporation of recycled materials. Therefore, the direct comparison of the environmental performance of innovative partition walls against traditional solutions emerges as an environmentally sustainable path in the short and medium term. This aligns with the ongoing progress towards decarbonizing the building sector, not only in choosing more environmentally friendly solutions but also in improving the environmental performance of products through assertive changes.</p></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"12 ","pages":"Article 100179"},"PeriodicalIF":5.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666789424000175/pdfft?md5=b290f9436321db6c83b2198525c70571&pid=1-s2.0-S2666789424000175-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140095954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Material Circularity Indicator (MCI) and the Circularity Index (CI) are incorporated into <em>openLCA</em>, and the LCA database <em>Ecoinvent</em> is adapted to trace circularity throughout. This allows to track circularity variables across supply chains and apply circularity indicators in LCA models. Results show that the LCA database mostly presents linear systems, with most datasets having a circularity values close to full linearity. Furthermore, investigations over the cradle-to-grave datasets of a Lithium-ion battery show that the amount of virgin material extracted from earth is actually 43 times bigger than the weight of the battery, and that the overall waste produced is 92 times the weight of the battery. Such high values are overlooked in common circularity indicator calculations.

The results indicate that when SCGs is used to power auxiliary processes, the CO<sub>2</sub> emissions greatly decrease, helping to reduce fossil fuel dependence. The study also reveals that scenarios using electricity from the Ecuadorian power grid exhibit lower environmental indicators than those using internal combustion engines.

To meet future legislation and environmental standards in this regard, organic micropollutants must be efficiently eliminated in the treated effluent. Innovative water treatment technologies can contribute to achieve this goal, but their environmental consequences must be controlled. The objective of this study is to assess the environmental hotspots of an enzyme-based wastewater treatment system for the removal of sulfamethoxazole (SMX) as a model pollutant. For this purpose, the Life Cycle Assessment and Product Environmental Footprint methodologies have been applied to a conceptual process design based on laboratory-scale data. In addition, we addressed the relevant process parameters (i.e., the stability and reuse of the enzyme and the impacts associated with its immobilization), the comparison with consolidated technologies (membrane and ozonation systems) and the geographical situation (such as the electricity mix and the water stress level). The main hotspot of the analyzed treatment process is the production of the unspecific peroxygenase used within the magnetic biocatalyst, contributing more than 36 % to all impact categories considered. Focusing on the magnetic biocatalyst synthesis, the enzyme production phase and the functionalization of the immobilization support are the most problematic (with percentages of up to 75 % in stratospheric ozone depletion and 65 % in terrestrial ecotoxicity, respectively). In relation to resource consumption, water demand has been estimated at 0.02 m<sup>3</sup> per cubic meter of treated water, but water deprivation can be much higher depending on the country (∼0.5 m<sup>3</sup>). Therefore, the use of reclaimed water can offset the indirect effects of its treatment. This study serves as a roadmap for future research to achieve reduced emissions by reduction of energy requirements, the use of renewable energy but also by increasing the enzyme stability. Furthermore, the background environmental impacts of the production of the biocatalyst must be reduced to improve the competitiveness against implemented alternatives based on physical (membranes) and chemical (ozonation) processes.</p></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"12 ","pages":"Article 100171"},"PeriodicalIF":5.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666789424000096/pdfft?md5=05b8c8efc3d2bab02e1bc02ed6cc7b8e&pid=1-s2.0-S2666789424000096-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139709516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wheat is a staple food in Morocco, as are legumes, which are present in a wide variety of Moroccan recipes and represent an important source of energy and nutrients. The present study evaluates the environmental performance of incorporating chickpea and lentils in a crop rotation system in Morocco that aims to decrease the environmental footprint of the traditional wheat-based crop. An attributional Life Cycle Assessment was conducted in three cropping systems that are grown in two-year cycles: R1 (chickpea:wheat), R2 (lentil:wheat) and M (wheat:wheat). Emissions were quantified in terms of life-cycle related environmental impacts and compared between cropping systems based on two functional unit (kg of wheat harvested). Rotation systems stand out as the most environmentally friendly, with the most notable reductions in the categories of stratospheric ozone depletion and water scarcity (34 % and 50 %, respectively). The environmental improvement from crop rotations was most significant when considering the calculation basis of hectare cultivated versus kg of wheat, which is due to the estimated yield trade-offs in both approaches. In terms of biodiversity loss, no significant differences were observed between crop rotations and monoculture, as the impact on this indicator is mainly attributed to land conversion pressures. This study provides guidance for better formulating crop rotation strategies in the Mediterranean and similar arid regions.

Yet, shortage of fertilizers and more frequent water stresses are challenging agricultural systems to minimize their environmental impact without compromising productivity and economic sustainability. This study discusses how greenhouse organic tomato production behaves when multiple eco-sustainable solutions are applied. In particular, organic tomato cultivation was supported by a specific biostimulant treatment that included a microbial solution, based on Rhizobium, which was distributed onto faba bean seeds; once a suitable fava bean biomass had been obtained, the plants were chopped and incorporated into the soil in order to release nitrogen. In the trials considered, microbial solutions reduced organic tomato production costs by 5 %. Considering that fertilization accounted for up to 7 % of total production costs, a large-scale preparation of the microbial solution could trigger significant economic savings. The Life-Cycle Assessment shows that organic tomatoes, with a lower yield, have a lower environmental impact than conventional production only for 7 of the 15 evaluated impact categories.
