This paper outlines challenges facing Australia in the context of international research trends for waste and waste reuse in a circular economy. Our understanding of the potential chemical hazards contained in our wastes and products with recycled content is a challenge due to the variability of waste and product materials. Such variability amplifies the need to ensure representative sampling to expand analytical and experimental methods and establish fundamental data and information related to chemical availability and ecological and human health effect. Four key themes are identified that need consideration, from identification of chemicals in our ever-diverse waste streams to dissemination of outcomes as guidance and for uptake in policy. Gaps in knowledge and the research required to address the four themes are outlined. The long-term development of an acceptable and consistent set of guiding principles related to the sampling, characterisation, categorisation and safe reuse of waste is shown to be important, further enabling resource recovery and reuse of materials.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"225 ","pages":"Article 108600"},"PeriodicalIF":10.9,"publicationDate":"2025-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145093933","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}

When corn residues (leaves and stalks) are recycled, these phytoliths serve as a vital and renewable Si source for subsequent cropping seasons. However, the dissolution behavior of corn-derived phytoliths remains poorly understood. This study investigates phytolith presence in soil-corn systems in Northern Vietnam, a region susceptible to intense leaching and Si loss. Corn residues were converted into phytolith-rich biochar and ash, and their dissolution properties were evaluated using batch experiments and scanning electron microscopy. In these batch experiments, the role of microorganisms, specifically <em>Bacillus velezensis,</em> in facilitating dissolution was also examined. Results indicate that corn accumulates Si primarily in its leaves (2.98 to 35.8 mg g⁻<sup>1</sup>), where condensed Si forms distinct structures such as thorn-like and bilobate phytoliths. The extent of phytolith dissolution, and thus Si release, depended on the corn leaf treatment. Over 14 days, Si release rates followed the order: ash (37.5 mg g⁻<sup>1</sup>) > biochar (11.6 mg g⁻<sup>1</sup>) > leaf powder with <em>Bacillus velezensis</em> (5.32 mg g⁻<sup>1</sup>) > leaf powder under sterile conditions (1.77 mg g⁻<sup>1</sup>). Among these approaches, producing phytolith-rich biochar under anaerobic conditions appears most effective, as it ensures prolonged Si availability while simultaneously contributing substantially to carbon sequestration. For situations requiring rapid and large-scale Si replenishment, direct combustion of corn residues, facilitated by microbial support, presents a suitable approach.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"225 ","pages":"Article 108593"},"PeriodicalIF":10.9,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145093935","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}

While climate policies have a relatively minor impact on material use patterns, CE policies could help achieve mitigation goals, highlighting the complementarity of both policies. To be effective, CE policies should include both supply- and demand-side interventions, which would achieve absolute decoupling.
