As the world population increases, the generation of waste bones will multiply exponentially, increasing landfill usage and posing health risks. This review aims to shed light on technologies for recovering valuable materials (, alkaline earth material oxide such as CaO, hydroxyapatite, beta tri-calcium phosphate, phosphate and bone char) from waste bones, and discuss their potential applications as an adsorbent, catalyst and catalyst support, hydroxyapatite for tissue engineering, electrodes for energy storage, and phosphate source for soil remediation. Waste bone derived hydroxyapatite and bone char have found applications as a catalyst or catalyst support in organic synthesis, selective oxidation, biodiesel production, hydrocracking of heavy oil, selective hydrogenation and synthesis of bioactive compounds. With the help of this study, researchers can gather comprehensive data on studies regarding the recycling of waste bones, which will help them identify material recovery technologies and their applications in a single document. Furthermore, this work identifies areas for further research and development as well as areas for scaling-up, which will lead to reduced manufacturing costs and environmental impact. The idea behind this is to promote a sustainable environment and a circular economy concept in which waste bones are used as raw materials to produce new materials or for energy recovery.
随着世界人口的增长，废弃骨头的产生量将呈指数级增加，这会导致垃圾填埋场使用量增加并带来健康风险。本综述旨在阐明从废弃骨头中回收有价值材料（如氧化钙等碱土金属氧化物、羟基磷灰石、β-磷酸三钙、磷酸盐和骨炭）的技术，并讨论它们作为吸附剂、催化剂和催化剂载体、用于组织工程的羟基磷灰石、用于能量存储的电极以及用于土壤修复的磷源的潜在应用。源自废弃骨头的羟基磷灰石和骨炭已在有机合成、选择性氧化、生物柴油生产、重油加氢裂化、选择性加氢以及生物活性化合物合成中用作催化剂或催化剂载体。借助本研究，研究人员可以收集有关废弃骨头回收利用研究的全面数据，这将帮助他们在一份文件中确定材料回收技术及其应用。此外，这项工作确定了进一步研究和开发的领域以及扩大规模的领域，这将降低制造成本并减少环境影响。其背后的理念是促进可持续环境和循环经济概念，即将废弃骨头用作生产新材料或进行能量回收的原材料。
