This study presents a robust model for predicting RDF's final lower heating value (LHV), introducing a novel cross-domain heating value prediction approach. The model achieved optimal performance under aeration rates (AR) of 0.2–0.4 m<sup>3</sup>/kg/day, coupled with organic content (OC) values between 0.94 and 1.88 m<sup>3</sup>/kg OC/day, accurately predicting final LHV values ranging from 3500 to 4500 kcal/kg. Results revealed that non-interaction variables and two-variable interactions significantly influenced heat value prediction and biodrying performance, yielding a 76 % coefficient of determination. A biodrying energy conservation index, based on the organic carbon (C) to organic hydrogen (H) ratio, was developed to assess the interplay between AR and final LHV. Results demonstrated an inverse relationship between the organic C-to-H ratio and the final LHV, with C retention and H release (1.48–2.28 %) enhancing energy yield. This study advances the understanding of biodrying by integrating independent variables for predictive modeling and conceptual indices for energy conservation, establishing a foundation for optimizing operational parameters in waste-to-energy systems. The findings provide practical guidance for sustainable waste management and support the production of high-quality RDF for renewable energy applications.</div></div>","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"197 ","pages":"Article 107795"},"PeriodicalIF":5.8,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143611090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the knowledge on the solid movement and the segregation patterns is a mandatory preliminary step for the setup of the final application. In this study, we evaluated the impact of particles size and density on the segregation patterns, and we used the Gibilaro and Rowe (GR) model to analytically represent the experimental results. It was observed that the variation of both parameters influences segregation, even though a higher separation degree in a wider operating velocity range was observed when a higher density ratio was induced between the two solids. Through the experimental analysis, five possible bed configurations were identified, and a consideration was made on the aims of the GR model to adjust the mathematical representation to the present case. By considering the bottom portion of the bed as a jetsam-rich phase and not – as previously reported – as a segregated layer, a mass balance on the catalyst allowed to obtain a faithful analytical representation of the experimental segregation patterns.</div></div>","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"197 ","pages":"Article 107764"},"PeriodicalIF":5.8,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143600610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, rice hull ash (RHA), wheat straw ash (WSA), and sugarcane bagasse ash (SBA) were treated to mineralize carbon, and their experimental carbon content was compared to modeled potential carbonation. To understand changes in the cement-based storage materials, mortars made with CO<sub>2</sub>-treated WSA and RHA were experimentally compared to PC-only mortars and mortars made with ashes without prior CO<sub>2</sub> treatment.

Ashes oxidized at 500 °C had the largest measured carbon content (5.4 g-carbon/kg-RHA and 35.3 g-carbon/kg-WSA). This carbon appeared to be predominantly residual from the biomass.
