Marine plastic pollution threatens coastal and island communities. Initiatives to reduce plastic have raised awareness and stimulated behavioral changes among local populations. The tourism sector represents a complex dynamic, serving as a significant industry that bolsters numerous communities’ local economies. While tourism contributes to increased plastic consumption, it also has the potential to support pollution mitigation efforts to preserve the reputation of these destinations. This study aims to examine the attitudes and behaviors in reducing marine plastic pollution, with particular attention to the impact of interventions and tourism, as there remains a shortage of understanding regarding the drivers that affect waste reduction in island contexts. Data were collected from 300 residents on two neighboring islands in Central Vietnam through questionnaires developed based on the Theory of Planned Behavior (TPB) with an extension to tourists’ moral behaviors and trust in authority. The Kruskal–Wallis tests and path analysis revealed that interventions substantially improved plastic waste reduction behaviors. Furthermore, all factors within the TPB framework and its extensions displayed positive correlations with intention and behavior; notably, perceived behavioral control and trust in authority exhibited stronger associations than other variables. Interventions were identified as positive predictors of behavioral change, likely attributable to educational activities, the distribution of reusable bags, and community engagement initiatives. Conversely, tourism was found to exert mixed effects: it could discourage anti-plastic practices, possibly due to economic priorities, while encouraging such practices when tourists exemplify pro-environmental behaviors. Essential policy implications for marine plastic pollution within island communities were discussed.

Forests are essential for global ecological stability, carbon balance, and the sustainable supply of roundwood resources. Forests in Japan are undergoing a policy-driven transition aimed at enhancing forest health and roundwood supply. This study presents the Forest Management Model for Cyclical Forestry (FM2-CF), a backcasting simulation model designed to support this transition over a 100-year horizon. The model integrates forest structural factors, forestry operational factors, and regulatory factors to investigate the long-term implications regarding Japan’s forest resources under the transition. It characterizes the national age-class transition of single-storied forests, quantifying roundwood supply and CO2 fixation potential. Regional analyses across all 47 prefectures reveal pronounced spatial disparities in forest resources, indicating the necessity of localized strategies. In addition, FM2-CF evaluates the required forestry operational efforts measured by forest area, labor force, and cost. The simulated forestry management has revealed a shift of operational focus from reforestation and weeding in the early stages toward more balanced harvesting and thinning activities in matured forests. Scenario-based projections of roundwood supply–demand dynamics have highlighted surpluses and shortfalls across regions and time. Our results provided insights into the sufficiency and timing of supply relative to evolving policy-related utilization demand. While the model is primarily structured as a supply-side strategic planning tool, it provides a valuable roadmap for aligning long-term forest renewal with sustainable management practices and assessing policy feasibility. Future extensions may incorporate growth modeling and demand-side mechanisms to improve applicability across broader contexts and other countries.

The valorization of construction and demolition (C&D) waste wood offers a sustainable avenue for meeting the increasing demand for renewable lignocellulosic resources in a circular bioeconomy. This study examines the physicochemical properties and fractionation behavior of C&D wood waste, comprising mixed softwood (MW), particleboard (PB), and fiberboard (FB), via three delignification strategies: acidic (acetic and formic acids), alkaline (sodium hydroxide), and neutral (ethanol-water) pulping. Compositional, structural, and thermal analyses of the raw materials revealed minor variations across the wood categories. Similar analyses of the resulting pulps showed that neutral and acidic treatments yielded better-preserved pulps in terms of compositional integrity and thermal performance, while alkaline pulping produced lower yields and the poorest pulp quality. Both acidic and neutral processes achieved high yields of pulp and lignin, with the neutral method producing lignin of the highest purity, thermal stability, and reactivity, as well as the lowest molecular weight. In contrast, lignin from the alkaline treatment exhibited the lowest purity and thermal stability. Acidic-extracted lignin had the highest molecular weight and moderate performance in other metrics. UV–visible spectrophotometry revealed predominantly non-conjugated phenolic structures in lignins from neutral and acidic treatments, whereas alkaline lignin contained conjugated phenolic structures.

Grinding swarf is a hazardous waste from the steel and manufacturing industry which is difficult to recycle due to its low value, heterogeneity, and distributed production across numerous workshops. Thousands of tons of grinding swarf are today landfilled, and the aim of this work was to propose an alternative recycling strategy and process for producing iron chloride water treatment coagulants from this waste. Two samples were leached with hydrochloric acid at pH 2 and 60°C for 3 h to extract up to 95% iron from the swarf by forming soluble ferrous chloride (FeCl2). The slurry pH was thereafter increased to 4 by adding more swarf, at which point chromium, aluminium and molybdenum were precipitated via hydrolysis. Nickel, cobalt, and copper could also be separated from FeCl2 by precipitation but were instead found to be cemented onto the swarf’s metallic iron surface. Nickel and cobalt cementation was facilitated by high chloride concentrations in the slurry. The investigated leaching and precipitation techniques were combined to propose a simple yet flexible process for producing water purification grade iron chloride from grinding swarf. Around 4.2 tons of 34% FeCl2 solution and 24 kg of hydrogen gas can be produced per ton of swarf as valuable products, promoting recycling and contributing towards zero-waste in the steel value chain.

The cement industry accounts for approximately 8% of global anthropogenic carbon dioxide emissions, underscoring the need for scalable in-material sequestration strategies. This study reviews current and emerging pathways for carbon dioxide sequestration in cement-based systems, focusing on process-based approaches such as accelerated carbonation curing and material-based strategies including mineral carbonation of alkaline byproducts like cement kiln dust and fly ash. The discussion is structured around three guiding questions: (1) how these approaches affect durability, strength development, and pore structure; (2) their economic feasibility and the role of enabling policy frameworks; and (3) optimal carbon dioxide incorporation levels that balance structural performance and environmental impact. Key findings include early-age strength gains from accelerated carbonation curing, pore densification with limited carbon dioxide diffusion, and corrosion risks in reinforced systems. Economic assessments estimate sequestration costs in the range of 25–56 United States dollars per metric ton of carbon dioxide, with particularly strong feasibility in precast concrete applications. Policy mechanisms such as carbon pricing, durability certification, and deployment subsidies are identified as critical enablers. Future opportunities include cast-in-place carbonation, low-purity carbon dioxide utilization, and life cycle-integrated curing strategies. By linking material science, engineering integration, and policy instruments, the paper outlines a comprehensive framework for advancing carbon-sequestering cement technologies in low-carbon construction.

The growing accumulation of plastic waste in landfills necessitates improved recycling methods. This study addresses the challenge of recycling acrylonitrile–butadiene–styrene (ABS) plastic by focusing on the removal of carbon black (CB) pigments, which complicate solvent-based recycling processes by affecting dissolution, purification, and the quality of recovered polymers. We developed an innovative Dissolution–Separation–Precipitation (D–S–P) method that utilizes a collector solvent to attract and remove carbon black (CB) through hydrogen bonding. The process was evaluated using color measurements, Fourier-Transform Infrared Spectroscopy (FTIR), Gel Permeation Chromatography (GPC), Differential Scanning Calorimetry (DSC), and Thermogravimetric Analysis (TGA) to assess the efficiency of CB removal and the preservation of ABS properties. This research introduces a novel approach for targeted pigment removal in ABS recycling, addressing a specific gap in current solvent-based recycling techniques that generally do not focus on pigment contaminants. The D–S–P process effectively removed CB, with the recovery of transmittance related with carbonyl groups approaching that of virgin ABS. Additionally, the analyses confirmed that the molecular weight distribution and thermal properties of the recovered ABS were well-preserved. The D–S–P method enhances the recyclability of ABS by efficiently removing CB pigments while maintaining the polymer’s mechanical and chemical properties. This approach not only improves the quality of recycled materials but also offers a practical solution for advancing plastic recycling technologies.

<div><div>Land subsidence in coastal cities may increase the risk of being submerged, and building load is one of the important causes of urban land subsidence. Considering the rapid urbanization of China, it is increasingly urgent to examine the impact of the growing building load on urban land subsidence in coastal cities of China. At present, few studies have introduced building weight as an indicator to characterize building loads, and there is a lack of large-area and multi-scale research on the relationship between land subsidence and building loads. On such a basis, this study raised a 10 m resolution urban building weight estimation method, and proposed a multi-scale, multi-index, and multi-subsidence-level investigation framework for the relationship between urban land subsidence and building load. Specifically, XGBoost model was applied on Sentinel images and OSM data to estimate the building floors in Shanghai; Then, building material intensity factors and building type vectors were introduced and combined with the estimated building floors to calculate building weight(The total weight was 2.12×10<sup>9</sup> t, the weight per unit area was 1.46×10<sup>6</sup> t/km<sup>2</sup>, the average weight exceeded 5,000 t). Meanwhile, SBAS-InSAR technology and Sentinel data were employed to obtain the land subsidence situation in Shanghai from 2015 to 2022(The average subsidence rate ranged from -18.25∼12.19 mm/y, the cumulative subsidence range was -128.71∼79.10 mm). Subsequently, the relationship between urban land subsidence and four building load indicators (building weight, building floor, building volume, and building density) at multi-scale (pixel, building, block, and grid) and multi-subsidence levels (all areas, subsidence area, and severe subsidence area) were revealed. The main findings could be demonstrated as follows: <strong>(1)</strong> the correlation between building weight and land subsidence was more significant than other building load indicator(-0.22∼-0.15 versus -0.20∼-0.02 at block scale); <strong>(2)</strong> in areas where subsidence has already occurred, places with heavy building weight would be more likely to aggravate subsidence(-0.22∼-0.04 versus 0.05∼0.07 at block scale); <strong>(3)</strong> the relationship between building loads and land subsidence in various scales were significantly different, the negative impact of building loads on ground subsidence would be more pronounced on a large scale(-0.22∼-0.15 at block scale versus -0.12∼-0.01 at pixel and building scale); <strong>(4)</strong> the construction loads of residential buildings would be more likely to cause land subsidence than other building types(-0.15∼-0.09 versus -0.02∼-0.01 at building scale).

Electronics repair is a core component of a circular economy, yet the many social, technical, and financial barriers limit the widespread adoption of repair practices along the value chain. The high complexity of electronics, reinforced by product design choices, and a perpetuating culture of consumption has normalised replacement when a fault occurs. Similarly, a lack of technical knowledge, uncertainty of repair outcomes, and opaque repair pricing make electronics repair particularly challenging for repair actors. However, existing literature lacks a comprehensive overview of the barriers and enablers perceived by the actors involved in the repair process, and how they influence the repair journey. To address these gaps, this study conducts a scoping review and interviews to understand the root causes of barriers and enablers of repair. The main barriers identified are the (assumed) affordability of repair services, repair not being front of mind for consumers, and the availability of spare parts, tools, and repair guides. These issues are largely attributed to upstream issues with product design, supplier agreements, and business operations lacking thoughtful construction to enable a smooth repair process. Our findings support the conceptualisation of the repair journey with interconnected barriers and enablers influencing decision-making in each stage. Building on this framework, we also present intervention opportunities for brands and manufacturers to facilitate repair along the repair journey.

The high complexity of electronics, reinforced by product design choices, and a perpetuating culture of consumption has normalised replacement when a fault occurs. Similarly, a lack of technical knowledge, uncertainty of repair outcomes, and opaque repair pricing make electronics repair particularly challenging for repair actors. However, existing literature lacks a comprehensive overview of the barriers and enablers perceived by the actors involved in the repair process, and how they influence the repair journey. To address these gaps, this study conducts a scoping review and interviews to understand the root causes of barriers and enablers of repair. The main barriers identified are the (assumed) affordability of repair services, repair not being front of mind for consumers, and the availability of spare parts, tools, and repair guides. These issues are largely attributed to upstream issues with product design, supplier agreements, and business operations lacking thoughtful construction to enable a smooth repair process. Our findings support the conceptualisation of the repair journey with interconnected barriers and enablers influencing decision-making in each stage. Building on this framework, we also present intervention opportunities for brands and manufacturers to facilitate repair along the repair journey. Future research should be conducted to measure the behavioural outputs of policy interventions designed to incentivise repair.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"29 ","pages":"Article 200304"},"PeriodicalIF":6.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145924757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Olive tree prunings (OTP), traditionally burned in the field and associated with pollutant emissions, represent a largely underutilised renewable resource in olive-growing regions. This study presents an integrated GIS–MILP methodology to quantify how supply chain design influences OTP mobilisation for plastics-sector intermediates in Andalusia (Spain). Unlike previous GIS-based studies, the approach enables a regional-scale comparison of centralised and decentralised logistics configurations, accounting for harvest, chipping, storage, natural drying, and transport. The results indicate that decentralised systems outperform centralised ones by reducing transport distances and better matching the fragmented spatial distribution of OTP. In the centralised scenario, mobilisation costs reach 143€ t-1 with transport of fresh woodchips accounting for 60% of total mobilisation costs. The most cost-effective option for 1 refinery is the combination with 10 smaller storages, cutting cost to 124 €·t⁻¹ (−13%) by moving dried woodchips efficiently to the refinery. The analyses provide insights to guide the development of regionally targeted bioeconomy and circular-economy policies and strategies by identifying efficient, scalable logistics configurations for agricultural residue valorisation.
