Several countries around the world are confronted solid waste management most especially from aluminum beverage containers. The recycling process is seen as an effective approach since it is energy saving, cost effective and reduced emission. In this study, the Sol-gel method was used to process the aluminum wastes and to consequently synthesize them into aluminum oxide (α-Al₂O₃) and presented in several crystalline structures. The result from this study indicated that the synthesized α-alumina at lower calcination time exhibited a lower FTIR peak intensity which indicated a more crystallinity. However, the synthesized α-alumina exhibited higher and sharper FTIR bands at higher calcination time. Moreover, the morphological characteristic shows that exhibited almost similar features with a non-spherical heterogeneous particle sizes. The results of the elemental analysis suggest a direct proportionality between the calcination time, and atomic percentage of aluminum among the samples. Conclusively, this study shows that the waste aluminum can be converted into economical value-added products.

世界上许多国家都面临着固体废物管理，尤其是铝制饮料容器。回收过程被认为是一种有效的方法，因为它可以节省能源，节省成本并减少排放。在这项研究中，使用溶胶-凝胶方法来处理铝废料，并因此它们合成为氧化铝（α-Al系₂ ö ₃）并以几种晶体结构呈现。这项研究的结果表明，在较低的煅烧时间下合成的α-氧化铝表现出较低的FTIR峰强度，表明具有更高的结晶度。然而，合成的α-氧化铝在更高的煅烧时间下表现出更高和更清晰的FTIR谱带。而且，形态特征显示出具有非球形异质粒径的几乎相似的特征。元素分析的结果表明，煅烧时间与样品中铝的原子百分比之间存在直接比例关系。总之，这项研究表明，废铝可以转化为经济的增值产品。
