Sustainable and reliable bioconversion is desirable to achieve optimal economic and environmental outcomes. Thus, science and industry require an accessible research platform to study complex bioconversion processes under conditions mirroring industrial-scale settings. In this study, industry-relevant respiration chambers were designed, tested, and replicated for BSFL feeding trials. Each open-circuit chamber housed three industrial rearing crates. The substrate/frass and air temperature, mass change, NH<sub>3</sub> and CO<sub>2</sub> emissions, and relative humidity were measured. The design was validated for CO<sub>2</sub> recovery, airtightness, airflow homogeneity, and BSFL performance using firstly, a uniform control substrate and secondly, uniform food waste across four parallel chambers. In a third trial, the composition of food waste was varied across parallel chambers to detect differences in metabolic processes. For trials using uniform substrates, low variability across chambers in performance parameters confirmed the reproducibility and comparability of the design (e.g. bioconversion rate: <1%, final larval mass: ≤2 mg, standard deviations, dry matter based). In contrast, the trial with varying food waste compositions showed a strong effect on average substrate/frass temperature (e.g. 31.5 °C vs 41.8 °C) and final dry larval mass (e.g. 67 mg vs 40 mg). This is the first study to systematically assess heat generation directly from heterogeneous food waste, a crucial parameter for efficient BSFL bioconversion. These chambers provide an opportunity for science and industry to thoroughly assess and understand the metabolic bioconversion characteristics. The findings are key for the optimisation of sustainable bioconversion processes.</div></div>","PeriodicalId":23969,"journal":{"name":"Waste management","volume":"193 ","pages":"Pages 409-418"},"PeriodicalIF":7.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142898631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study proposes a new method combining high-temperature reaction with CaO addition, selective leaching, and chemical precipitation for efficient and low-cost phosphorus recovery from ISSA. During thermal treatment at 1050 °C, the addition of CaO significantly influenced the types and amounts of phosphate mineral phases in ISSA. When 20 % CaO was added, the Al/Fe-phosphate phases were completely converted into acid-soluble Ca-phosphate phases, while Al and Fe were retained in acid-insoluble phases (e.g., Al- and Fe-containing oxides and silicates). Subsequently, by controlling the pH of acidic leachate (2.0 to 1.5), Ca-phosphate phases were selectively dissolved. At a pH of 1.5, better selective leaching was achieved, with a leaching efficiency of 94.71 % for P and less than 10 % for Al, Fe and Si.
