The present article, based on reverse logistic, provides an environmentally beneficial and cost-effective method of producing calcium phosphate bioceramics (potassium calcium phosphates) aimed for soil conditioning, by a free-solvent mechanochemical process between eggshell waste and KH2PO4. The K3CaH(PO4)2 and possibly CaKPO4 phases formed provide a better nutrient management of P, K and Ca, when applied in soil system the material first release K and form hydroxyapatite and important P and Ca bioavailable source at pH ∼ 5, which comprises a large part of many countries soils.

以蛋壳（方解石）和 KH2PO4 机械化学合成环保肥料
本文基于逆向物流，提供了一种生产磷酸钙生物陶瓷（磷酸钙钾）的环保且具有成本效益的方法，该方法旨在通过蛋壳废物和 KH 2 PO 4之间的无溶剂机械化学过程来调节土壤。形成的 K 3 CaH(PO 4 ) 2和可能形成的CaKPO 4相提供了更好的 P、K 和 Ca 养分管理，当应用于土壤系统时，该材料首先释放 K 并形成羟基磷灰石和重要的 P 和 Ca 生物可利用源，pH 〜 5，其中包括许多国家土壤的很大一部分。
