While concepts such as closed-loop systems, Life-Cycle-Thinking (LCT) and circular design have been at the forefront of international discourse for decades, researchers and developers often struggle addressing, communicating and engaging holistically with the relevant topics and stakeholders. This hesitancy limits the critical assessment of their contributions to circularity, safety and sustainability, and ultimately their impact. This paper comprehensively explores the complexities of integrating circularity into novel biomanufacturing research that valorises waste- and side streams. We propose addressing these intricacies by making frameworks like Safe-and-Sustainable-by-Design (SSbD) and LCT more accessible to early-career researchers who work on circular (bio)economy topics, which increasingly require transdisciplinary collaboration and approaches to thrive. Here, we use a combinatorial approach to shed light on this topic, undergoing a desk study, semi-structured expert interviews, and integrating a hands-on experimental project to our learnings, where we applied the SSbD concept to early experimental decision-making and for critical reflection. Moreover, we present an overview of concept levels that should be assessed to understand the impact of a production process, highlight key EU regulatory frameworks, and showcase relevant literature for a structured approach for more sustainable development in manufacturing. Our findings emphasise the lack of a clear waste definition and management consensus, unfair competition with the highly optimised, subsidised, fossil-based industries, misaligned regulation to facilitate international resource management and infrastructure, and the absence of standardised, holistic cost-environmental-social impact assessments.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"528 ","pages":"Article 146685"},"PeriodicalIF":10.0,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145209395","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}

Wetting the clay surface with paraffin oil improved the processability of the nanocomposites.

The mechanical properties can be adjusted by varying the ratios of rubber, clay, and carbon black. Based on this, in order to reduce subsequent mechanical mixing pollution and decrease the mixing time, carbon black was dispersed in water, and SBR/clay/carbon black nanocomposites were prepared using emulsion blending. Compared with the mechanical mixing, the SBR/clay/carbon black nanocomposites prepared using emulsion blending exhibited better mechanical properties, wet skid resistance, and lower rolling resistance. This approach allows the clay to reduce the amount of raw rubber and carbon black required in the final rubber products, thereby reducing petroleum consumption, lowering costs, reducing carbon emissions, and reducing pollution during the production process.

We quantified N inputs (seed, fertilization, atmospheric deposition), outputs (crop uptake, NH<sub>3</sub> volatilization, N<sub>2</sub>O emissions, and leaching), and soil N retention over two growing seasons with contrasting rainfall patterns. Reducing N inputs generally decreased gaseous N losses, crop N uptake, and grain yield, ultimately lowering overall N balance. Regardless of application rate, deep N placement significantly reduced gaseous N losses and improved crop N uptake compared to shallow placement (5 cm), effectively compensating for yield losses due to reduced N application. A 15 % N reduction combined with 25 cm placement resulted in the lowest N balance and highest economic return by minimizing both gaseous and hydrological N losses. This combination also increased crop N uptake and grain yield by 13.8 % and 12.5 %, respectively, relative to the conventional practice. Moreover, deep placement with reduced N demonstrated greater resilience to extreme rainfall, helping to stabilize N balance.

Using Minitab to simulate the optimal raw material ratio (61.4 % dredged sediment, 14.4 % sewage sludge, and 24.2 % fly ash), we obtained ceramic particles with high P adsorption capacity (0.750 mg/g) and porosity (36.8 %).

Even under strong winds, the P release flux in the backfill group decreased by 87.2 % compared with the control. The process also followed the principle of “treating waste with waste,” as P resources were recovered using a simple NaOH leaching agent, enabling regeneration and reuse of the ceramic particles—remarkably, regenerated particles maintained adsorption performance with only minimal decline.
