Geopolymers offer better mechanical performance and resistance to aggressive environments under these circumstances. The present study evaluates the mechanical and durability performance of various geopolymer concretes designed from fly ash, blast furnace slag and metakaolin activated by sodium hydroxide and sodium silicate solutions. Two curing regimes, ambient room curing and 70⁰ C curing for 24hrs have been adopted to verify the influence of curing temperature on the concrete properties. To mimic the airbase apron conditions, the samples have been submerged in aviation oils and subsequently exposed to flame to check their mechanical strength and dimensional stability. Though samples made from combination of fly ash, slag and metakaolin in the ratio of 20 %, 50 % and 30 % by weight respectively, displayed better mechanical performance, resistance to acid and aviation oils test, it offered poor workability with minimal setting making it difficult for field applications. Geopolymer mix with fly ash, slag and metakaolin in 40 %, 30 % and 30 % by weight have displayed acceptable durability performance and superior mechanical strength with good workability making it an ideal design mix for airbase applications. The study also evaluates the environmental life cycle assessment (cradle to gate) of the geopolymer concrete and compares them with a 35 MPa cement concrete. All geopolymer concrete mixes on average displayed 60 % less global warming potential in comparison with cement concrete. Geopolymer mixes containing metakaolin, displayed higher mineral resource depletion compared to their cement concrete counterpart.</div></div>","PeriodicalId":100256,"journal":{"name":"Cleaner Waste Systems","volume":"11 ","pages":"Article 100278"},"PeriodicalIF":0.0,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143777465","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}

This study evaluated the impacts of cotton and hemp fiber production through a comparative environmental life cycle assessment, focusing on farming, harvesting, and fiber processing. The functional unit used was 1 hectare of cultivated land. Using data from peer-reviewed literature, eutrophication, global warming, and acidification potential of producing these fibers was quantified. While both fibers presented impacts in these three categories, cotton demonstrated the highest impacts in all three (69.6 kg N eq. for eutrophication, 7903 kg CO₂ eq. for global warming potential, and 65 kg SO₂ eq. for acidification). Not only did hemp exhibit lower impacts (3.6 kg N eq. for eutrophication, 1374 kg CO₂ eq. for global warming potential, and 15 kg SO₂ eq. for acidification), but it also offered secondary benefits such as carbon sequestration and versatile uses. Due to data limitation, a sensitivity analysis was conducted to assess the impact of variation (± 20 %) in key inputs: energy, electricity, and fertilizer usage. Overall changes to all three impact categories were well below the 10 % threshold for both fibers, suggesting the processes evaluated are reliable and easy to manage under varying conditions. However, more innovative and systematic changes such as the use of more efficient equipment, are needed.

The physical, mechanical and sustainability performance of the concrete samples were examined in detail. In addition, the behavior of concrete under the influence of fire temperature with WSR was also examined in detail. The specimens were subjected to a temperature of 200, 400, 600, and 800 °C following ISO 834 standard time-temperature curve. The physical changes, surface modification, mass loss, porosity, residual strength was examined in detail and the same was compared with the control concrete values obtained prior to temperature exposure. The concrete developed with WSR possess larger strength variation before heating, showing that the WSR had a direct influence on the strength of the mix. For the initial replacement levels, 25% loss was seen, whereas partial replacement of conventional coarse aggregate with WSR possesses 77% loss. After subjecting to 200 °C, marginal variation in strength was seen, whereas after subjecting to 400 °C, the loss was pronounced, for the mix with 50% WSR, the loss was seen to be 33%. Moreover, after subjecting to 600 °C, 50–60% strength loss was seen for the higher proportions of WSR. After 800 °C, the concrete samples with WSR tends to collapse without taking any load.

Spatial data was processed and analyzed using Landsat 7TM in ArcGIS for 2000 and Landsat 8 for 2020 in a remote sensing environment was used to categorize four land use classes, and change detection matrix to detect the extent of urban growth for the study. Non-spatial data was collected from households using Kobocolect toolbox. Near matrix was further conducted to measure household proximity to water distribution pipelines in the Metropolis. The study revealed that only 66 % of the households in the study area are within the UN’s requisite radius of 500 m to water distribution pipelines, with the rest relying on private water vendors and dams for their water needs. The undertaken overlay analysis shows that households that are within the inner ring of the distribution lines are those largely connected to pipe water supply.

Effective and technically feasible short- and medium-term plans are needed to meet set targets. This study aims to characterize MSW composition in Tuscany, Italy, using a standardized and updated procedure. All collected fractions, including the residual waste component, were analysed to provide an overall balance of waste produced and assess the separate collection efficiency. Biodegradable organic material was the largest category identified, although it remained below 30 %, placing it in the lower range of values reported in the literature. Paper and cardboard comprised the second-largest category (21.3 %), followed by plastics (16.3 %). When comparing collection models, the door-to-door method proved more effective than street-bin collection, significantly reducing impurities across all separately collected fractions. More than 50 % of residual waste consisted of recoverable materials, indicating the need for greater public engagement. Metals and plastics, despite having well-established recovery circuits, showed the lowest capture efficiency within separate collection systems. A redesign of the extended producer responsibility scheme could enhance their capture rate, as it currently limits accepted items to packaging. Introducing dedicated collection and recovery channels for textiles and diapers (about 15 % of MSW) could further reduce “residual waste” to a truly residual fraction.</div></div>","PeriodicalId":100256,"journal":{"name":"Cleaner Waste Systems","volume":"11 ","pages":"Article 100272"},"PeriodicalIF":0.0,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143738645","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}
