The meat industry generates a significant amount of hazardous waste, containing phosphorus, calcium, and other elements which could be the basis for other products. This work presents the results of research on the thermal utilisation of bone meat waste and the use of the ash thus obtained as a substitute for phosphorus raw materials. Material Flow Analysis was used to quantify and assess the option with the highest material productivity. Such a solution can be in line with an updated pyramid of food waste hierarchy already proposed in the literature, distinguishing surplus food and a new category for recycling of materials, in analysed case food waste, in the circular economy. The research is based on the example of real data from a Polish meat producer. The quantity of waste from primary production and meat manufacturing containing waste bone in Poland was estimated to be 232,000 t/y (24.0% of the total quantity of meat waste). Its thermal utilisation potentially allows 71,118 t/y of hydroxyapatite ash, a substitute for phosphorites, to be obtained. The high quality hydroxyapatite ash could be used for the production of food grade phosphoric acid and also for the production of food grade mono- and dicalcium feed phosphates.

肉类工业会产生大量危险废物，其中含有磷、钙和其他元素，这些元素可能是其他产品的基础。这项工作介绍了骨肉废料的热利用研究结果，以及利用由此获得的灰分作为磷原料的替代品。材料流分析用于量化和评估具有最高材料生产率的选项。这种解决方案可以与文献中已经提出的更新的食物垃圾等级金字塔相一致，在循环经济中区分剩余食物和材料回收的新类别，在分析的情况下食物垃圾。该研究基于波兰肉类生产商的真实数据示例。波兰初级生产和肉类制造中含有废骨的废物量估计为 232,000 吨/年（占肉类废物总量的 24.0%）。其热利用可能允许获得 71,118 吨/年的羟基磷灰石灰分，这是磷灰石的替代品。高品质羟基磷灰石灰可用于生产食品级磷酸，也可用于生产食品级磷酸一钙和磷酸二钙。
