However, the abundant ether groups and aromatic skeletons in epoxy resin made it difficult to withstand radiation of ultraviolet, leading to the limited outdoor lifespan of epoxy-based transparent bamboo. Existing research on UV resistance improvement is fragmented, and the contradiction between anti-UV aging performance and structural rigidity remains unresolved, limiting practical outdoor applications. In this study, an ultraviolet-resistant transparent bamboo (URTB) is constructed using the hydrogenated epoxy resin modified by ultraviolet absorbing and hindered-amine light stabilizer as the hybrid matrix. The light transmittance, high haze, low thermal conductivity, and water contact angle of URTB reach 80%, 95.89%, 0.245 W/(m·K), and 99.68°, respectively, which provide simultaneous light transparency, inner privacy, heat preservation, and water resistance. When the outdoor temperature reaches 36 °C, replacing ordinary glass with URTB in an office building achieves 66.8 kWh daily energy savings and 40.08 kg CO<sub>2</sub> emission reduction. Moreover, after 12 days of UV-accelerated aging, the URTB shows only a 3.09% transmittance decrease, while its tensile strength increases notably from 109.1 MPa to 127.8 MPa. The superior UV resistance of URTB originates from the stability, ultraviolet absorption, and free radical-scavenging capabilities of the hybrid epoxy matrix, forming a three-step anti-ultraviolet mechanism of “source inhibition-energy interception-damage termination”. This enables URTB to withstand UV radiation and maintain stable performance in outdoor applications such as building facades, skylights, and sunrooms. This study paves the way for extensive outdoor applications of transparent bamboo in green and sustainable construction.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"549 ","pages":"Article 147810"},"PeriodicalIF":10.0,"publicationDate":"2026-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147292487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biomass availability, including non-delimbed and delimbed energy wood, residues, and surface woody debris, was evaluated in a 12-ha forest stand in the interior of BC, Canada. Woodchip quality was analyzed for particle size distribution, ash content, moisture content, and bulk density. Supply chain costs were estimated for multiple recovery methods, machinery scales, and chipping locations, considering specific treatment options. Results showed that one year of natural air drying enabled non-delimbed and delimbed energy wood to meet CHP system requirements for particle size and ash content, whereas residues and woody debris required targeted post-processing. Supply chain costs ranged from $175-426 per oven-dry tonne, driven primarily by transportation distance and treatment intensity. These findings demonstrate that fuel-reduction biomass can support small-scale CHP system operations when feedstock is locally sourced and of sufficient quality. Integrating energy production with higher-value product streams may provide a practical approach to cost-effective biomass utilization while contributing to wildfire risk mitigation, local energy security, and the regional bioeconomy.

Existing approaches predominantly focus on single-stage optimization or static pricing assumptions, lacking the integration of workload allocation strategies and adaptive procurement decisions in a stochastic environment. To address these gaps, we propose a two-stage joint optimization and reinforcement learning (RL)-based framework for carbon management. In the first stage, computational workloads are dynamically allocated across geographically distributed IDCs according to regional carbon intensity, aiming to reduce operational emissions. In the second stage, a Soft Actor–Critic (SAC)-based RL model is developed to optimize continuous carbon allowance purchasing decisions under market uncertainty. The proposed framework introduces three major innovations: (i) a two-stage joint optimization that bridges emission reduction scheduling and strategic carbon allowance procurement; (ii) an endogenous carbon price modeling mechanism that captures market dynamics and price-demand interactions; and (iii) a SAC-based RL approach that leverages entropy-regularized exploration and multi-objective reward integration to ensure robust, cost-effective procurement strategies. Experimental results demonstrate that the proposed framework reduces annual carbon procurement costs by 5.90%–7.38% compared to benchmark strategies, while maintaining compliance, reducing carbon emissions, and avoiding excessive inventory. These findings highlight the potential of combining joint optimization and deep RL for sustainable and economically efficient data center operations. Specifically, the 5.90%–7.38% reduction in procurement costs compared to benchmark strategies not only improves operational efficiency but also promotes sustainability by reducing carbon emissions, highlighting the framework’s dual impact on both cost and environmental performance.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"549 ","pages":"Article 147822"},"PeriodicalIF":10.0,"publicationDate":"2026-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147292485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The recycling system includes four stages: dismantling, transportation, treatment, and material regeneration, and covers five major technologies: mechanical recycling, thermal recycling without glass recovery, thermal recycling with 90% intact glass and 10% crushed glass, chemical recycling, and Full Recovery End-of-Life Photovoltaic. Life Cycle Assessment comprehensively evaluates their carbon emissions, costs, and mitigation potential. Under carbon policy scenarios, Evolutionary Game Theory simulates strategic interactions among governments, manufacturers, and recyclers, integrating system dynamics to analyze evolutionary stability, followed by sensitivity analysis of key parameters. Results show substantial differences in carbon emissions and mitigation potential across technologies. Mechanical recycling has the lowest process emissions (702.2 kg CO<sub>2</sub>/t) but limited reduction potential (−4612 kg CO<sub>2</sub>/t), whereas Full Recovery End-of-Life Photovoltaic has higher emissions (1113 kg CO<sub>2</sub>/t) but achieves the greatest mitigation (−5694 kg CO<sub>2</sub>/t).

Results indicate that for the unrecuperated cycle, utilizing compression heat for the chiller and exhaust heat for desalination (Scenario 1) offers the best overall performance, achieving energy and exergy efficiencies of 70.79 % and 52.77 %, respectively, along with a fuel energy saving ratio of 30.02 %. Additionally, annual reductions in carbon dioxide, carbon monoxide, and nitrogen oxides emissions reach 103,173, 561, and 69 tons, respectively. These findings demonstrate the significant potential of thermally integrated gas turbine–based polygeneration systems to enhance energy utilization and environmental sustainability.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"548 ","pages":"Article 147846"},"PeriodicalIF":10.0,"publicationDate":"2026-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146777535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
