However, charcoal quality varies based on wood species and carbonization methods, impacting performance during grilling. Charcoal must provide consistent heat, with factors like burn duration and residue affecting cooking quality and costs. This study evaluated 23 commercial charcoal samples in Italy—15 lump charcoals and 8 briquettes. It analyzed their quality and combustion performance through proximate, physical analyses, and combustion tests on a commercial barbecue measuring weight loss, burning rate, residue, ember, and fume temperatures. Proximate analysis revealed significant heterogeneity, with some samples exhibiting moisture content (up to 11.7%), ash levels (up to 35%), and volatile matter (up to 30%) outside the recommended threshold set by EN 1860–2:2023 standard, which negatively impacted combustion efficiency. Key factors like high fixed carbon (&gt; 75% for 10 lump charcoal samples) and heating values (&gt; 27 MJ/kg for most lump charcoals) promoted more complete combustion with higher weight loss, burning rates, and ember/fume temperatures. Lump charcoals generally showed better combustion performance than briquettes, with higher temperatures (up to 600 °C for embers and 60 °C for fumes) and lower residues. However, briquettes exhibited a more prolonged burn duration and lower fume/ember temperatures (&lt; 500 °C). The granulation and apparent density also influenced combustion, with smaller charcoal fractions improving burning rates. The results emphasize the significant influence of product quality and variability on combustion behavior, underscoring the necessity of rigorous production and distribution standards to ensure optimal grilling performance of charcoal-based fuels.</p></div>","PeriodicalId":488,"journal":{"name":"Biomass Conversion and Biorefinery","volume":"15 18","pages":"24995 - 25006"},"PeriodicalIF":4.1,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13399-025-06830-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145190194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these pineapple crowns (PaCn) are rich in bioactive compounds and chemicals, offering vast potential for applications in pharmaceuticals, cosmetics, food and beverages, biofuels, bioplastics, paper and pulp products, etc. The previous review reports on the subject examined the development of sustainable materials derived from different pineapple wastes, i.e., peel, core, crown, and pomace in the bioenergy and other industrial sectors. However, they have not focused on application materials derived from waste PaCn. Hence, there is a scope for exploring the different application materials derived from PaCn. This first report thoroughly reviews waste pineapple crowns’ industrial potential, possibilities for by-product valorization, and their conversion process. Through the thorough literature review, it is perceived that various industries can derive multiple value-added products from waste PaCn, including 15 application materials such as nano/micro cellulose, activated carbon, enzymes, fibers, vanillic acid, bioadsorbent, regenerative cellulose, renewable aromatic compounds, pharmaceutical chemicals, reducing sugar, bioactive compounds, corrosion inhibitor, bio-oil, composite particles, and mortar. The waste of PaCn conversions has been shown to reduce waste generation, and the products derived from the conversion would support the waste-to-value concept.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":488,"journal":{"name":"Biomass Conversion and Biorefinery","volume":"15 18","pages":"24755 - 24772"},"PeriodicalIF":4.1,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145190271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
