Due to the extensive length of the territory studied, it is demonstrated that the environmental impacts depend on the geographical location where the heating equipment is used. Stoves that use wet firewood presented the highest environmental impact in CC, PM, HT, and PO. Using dry firewood could reduce pollution by 14%–81%, compared to wet firewood. Replacing wood heating with natural gas, LPG, and kerosene stoves reduces the CC and HT indicators. On the other hand, switching to electric heating, such as split inverter heat pumps, could transfer these impacts to areas where electricity is generated using coal. When the pellet is a byproduct of the forestry industry and transportation distances are not very high, the pellet stove stands out for its lower CC. In Magallanes, electric heating appears environmentally attractive due to using natural gas for electricity generation.</p></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"13 ","pages":"Article 100192"},"PeriodicalIF":5.0,"publicationDate":"2024-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666789424000308/pdfft?md5=bd094b47f61269b5fb3dffe1cb2634f3&pid=1-s2.0-S2666789424000308-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140879686","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 functional unit was the food required to meet one person's yearly needs (1 Inh/year). To determine the quantity and type of food consumed, as well as the income level of the residents, 523 surveys were conducted in households in four cities in Chile (Iquique, Santiago, Temuco, and Coyhaique). Survey data were complemented with secondary information from national statistics and the Ecoinvent database. The environmental impact assessment was carried out using SimaPro, selecting the categories of global warming, terrestrial acidification, terrestrial ecotoxicity, freshwater ecotoxicity, freshwater eutrophication, land use, and fossil resource scarcity. The results show that higher-income households generate greater environmental impacts attributed to higher per capita food consumption. In the global warming category, the environmental impact can range from 1.08 kg CO&lt;sub&gt;2&lt;/sub&gt; eq/inh/year for the first quintile to 2.15 kg CO&lt;sub&gt;2&lt;/sub&gt; eq/inh/year for the fifth quintile in Santiago. In this category, the impacts in the highest quintiles can be up to 2.2 times greater than those in the lowest quintiles. Similarly, in acidification, this difference can reach 2.3 times. In the freshwater eutrophication category, the highest-income quintiles can double the environmental impacts compared to the lowest (I and II), mainly due to higher consumption of red meat and dairy products. The food production stage was the environmental hotspot across all evaluated impact categories, accounting for 45%–60% of the impacts in global warming, terrestrial ecotoxicity, and fossil resource scarcity; 74%–78% in terrestrial acidification, freshwater eutrophication, and land use; and 68%–71% in freshwater ecotoxicity. Meat was pinpointed as the primary environmental hotspot in global warming (44%), terrestrial acidification (56%), freshwater eutrophication (50%), land use (35%), and fossil resource scarcity (30%). Conversely, cereals are the primary environmental hotspot in terrestrial ecotoxicity (30%) and vegetables in freshwater ecotoxicity (18%). The geographical location of cities also influenced the environmental impacts of food consumption, primarily due to the types of available foods in regions near each city. Food availability conditions, diets, and quantities consumed, thus influencing environmental impacts. Finally, household incomes, the geographical location of cities, and the food production systems in each city determine the environmental impacts of food consumption.

We developed a data-driven framework by integrating machine learning with life cycle thinking that can be used as an open-source tool to help overcome these barriers. The framework was applied to compare two emerging technologies: pyrolysis versus hydrothermal carbonization for managing the excess poultry litter in a rural agricultural region. Among different machine learning models, random forest regression was the most successful to predict resource recovery of both technologies. Next, sustainability analysis indicated that the environmental (global warming), economic (annual worth), and social (system intrusiveness) impacts of pyrolysis was lower than hydrothermal carbonization. Finally, the framework revealed that implementation of pyrolysis at 600 °C for 1 h with the heating rate of 20 °C/min would result in the highest rate of resource recovery that corresponded to the lowest impacts. These results can be helpful in providing operational conditions for implementing emerging resource recovery technologies in rural agricultural regions.</p></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"13 ","pages":"Article 100188"},"PeriodicalIF":5.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666789424000266/pdfft?md5=706adcd01d9925330cc12b6a785600be&pid=1-s2.0-S2666789424000266-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140622346","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}

Effective data management is critical during the implementation of circular strategies; however, the academic literature does not explicitly address the subject, and a shared approach to data governance is still lacking. This study contributes to filling this gap by providing a holistic perspective to the state-of-the-art literature to identify the role of data in the implementation of CE strategies. The findings were obtained through the review of 40 articles. It was found that the literature can be classified into four interrelated thematic groups: the need for information and data, information and data management, the digitalisation of data and information, and digital tools and technologies. The study identifies the highlights for each thematic group and suggests opportunities to improve circularity through the effective use of data. It is important to recognize that accessible, open, and standardised information about construction products can accelerate the implementation of circular strategies in a project, but it is critical to ensure effective data management and interoperability throughout the asset life cycle. Therefore, data management tools and data templates need to be further investigated and adopted in the industry. Digital technologies can support data management and interoperability and, consequently, increase the possibility of successful CE implementation. Finally, future research should investigate a strategic approach to data exploitation that can enhance circularity in the built environment.</p></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"13 ","pages":"Article 100183"},"PeriodicalIF":5.0,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666789424000217/pdfft?md5=adcb4db51d6daf64d5b9466fb50944e2&pid=1-s2.0-S2666789424000217-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140607322","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}

Precision farming technologies, including robotics, are touted as having huge potential to increase farm productivity, reduce energy and resource use and compact soil, while reducing the overall environmental impact of on-farm production. This comprehensive study presents, for the first time, a detailed analysis and environmental benchmarking of two organic sugar beet production (SBP) systems, conventional (CONV) and robotic (RBT), based on field experiments in Lithuanian conditions where a solar-powered robot is integrated into the production system to carry out sowing and weeding operations. In order to reduce the potential environmental impact and to understand the consequences of using the robot in agriculture, a Life Cycle Assessment (LCA) of the entire SBP process up to the factory gate was carried out. The results of the analysis show that the conventional system has higher total GHG emissions than the robotic system, 36.98 and 27.18 kg CO_2eq t⁻¹, respectively, with poultry manure being the largest contributor. The higher beet yield in the RBT system, mainly due to effective weed control, resulted in a higher GHG emissions ratio (14.72) and a higher sustainability index (13.72). The LCA results showed that the CONV system had a higher negative environmental impact than the RBT in all eleven environmental impact categories assessed, with the most pronounced difference in the Ozone Depletion (OD) category. Diesel fuel was identified as the most important environmental factor for organically growing sugar beet in all considered impact categories, with the most notable environmental impact (about 94%) in the terrestrial ecotoxicity category in both systems. Normalization of the results showed that marine aquatic ecotoxicity (ME) had the greatest (78%) influence of all exposure categories for both cultivation systems, CONV – 22079.82, and RBT 18121.61 kg 1.4-DB_eq per ton of produced sugar beet.
