This study focused on the feasibility of identifying and recycling inorganic phase-change materials (PCMs) from sugar industry wastes in two cities of Qazvin and Hamadan in Iran. In this study, dry sugar beet pomace, sugar beet pomace, sugar beet molasses, leaves and plant residues of sugar beet and sugarcane bagasse were investigated. The inorganic materials were identified by X-ray Diffraction (XRD), thermal characteristics were determined by differential scanning calorimetry (DSC), and morphological characteristics were determined by scanning electron microscopy (SEM). Additionally, physical and thermal properties of molasses and bagasse samples were analyzed to determine their suitability as inorganic PCMs. The results of this study demonstrated that molasses and bagasse have the potential to be used as mineral PCMs in thermal energy storage applications. The results of this study demonstrated that in the wet sugar beet pomace the highest and lowest concentrations of inorganic PCMs were silicon dioxide (SiO) and sodium chloride (NaCl), respectively. Moreover, the highest calcium fluoride (CaF₂) composition was reported in dry sugar beet pomace. In the samples of leaves and residues of sugar beet and sugarcane bagasse, the highest concentration of was NaCl. The detection and recycling of mineral PCMs from sugar industry wastes offer a sustainable solution for waste management and provide a renewable source of thermal energy storage materials.: This study demonstrated the potential for the extraction of inorganic phase-change materials from sugar industry wastes as a means of solid waste management. By repurposing these materials, we can reduce the environmental impact of sugar production and contribute to sustainable practices in the industry.
本研究聚焦于从伊朗加兹温市和哈马丹市的制糖工业废料中识别和回收无机相变材料（PCM）的可行性。在本研究中，对干甜菜渣、甜菜渣、甜菜糖蜜、甜菜叶和植物残渣以及甘蔗渣进行了调查。通过X射线衍射（XRD）鉴定无机材料，通过差示扫描量热法（DSC）测定热特性，通过扫描电子显微镜（SEM）测定形态特征。此外，还分析了糖蜜和甘蔗渣样品的物理和热性能，以确定它们作为无机PCM的适用性。本研究结果表明，糖蜜和甘蔗渣有潜力在热能存储应用中用作矿物PCM。本研究结果表明，在湿甜菜渣中，无机PCM的最高和最低浓度分别是二氧化硅（SiO）和氯化钠（NaCl）。此外，干甜菜渣中氟化钙（CaF₂）的含量最高。在甜菜叶和残渣以及甘蔗渣样品中，含量最高的是NaCl。从制糖工业废料中检测和回收矿物PCM为废物管理提供了一种可持续的解决方案，并提供了一种可再生的热能存储材料来源。：本研究证明了从制糖工业废料中提取无机相变材料作为固体废物管理手段的潜力。通过重新利用这些材料，我们可以减少制糖生产对环境的影响，并为该行业的可持续发展做出贡献。
