Production of Animal Nutrient Phosphorus from Incinerated Waste Bone

Sanimax专门收集和回收农业食品工业的副产品。Sanimax是一家私营公司，于1939年开始运营。Sanimax目前在加拿大和美国的16个地点管理着各种各样的农业食品工业废物，并利用它们制造有用的产品。**一种大规模的废物是动物骨骼，这是畜牧业的副产品。**干燥后，骨骼的骨骼含量约为50%的胶原蛋白和其他蛋白质，50%的碳酸盐取代磷灰石（cAp）富含磷(P)。cAp是一种复杂的生物矿物，含有钙、磷酸盐、碳酸盐、氟化物以及较小浓度的镁和钠。经过热处理后，碳酸盐磷灰石中的碳酸盐含量以二氧化碳的形式散失，剩下的矿物称为羟基磷灰石（HAp）。不幸的是，碳酸盐磷灰石和羟基磷灰石都不是动物饲料的有效磷源，应减少氟化物含量。**这项Engage资助的目的是测试化学转化方法，以从Sanimax焚烧牲畜骨骼产生的HAp中创造有用的富含p的动物饲料**。从热处理的**骨矿物中溶解HAp和在消化过程中更容易吸收的另一种矿物的结晶，如**磷酸一氢钙（MCPM: Ca(H2PO4)2）。H2O)或二水磷酸二钙（DCPD:**CaHPO4.2H2O）是为**Sanimax从原料或热处理骨矿物中创建有用的富p饲料材料的选择。

Sanimax specializes in collecting and recycling by-products from the agri-food industry. Sanimax is a privately**owned company that began its operations in 1939. Sanimax currently manages a wide range of agri-food**industry waste, and uses them to create useful products at sixteen locations in Canada and the United States.**One large-scale waste product is animal skeletons, which are a by-product of the livestock industry.**After drying, the bone content of the skeleton is approximately 50 % collagen and other proteins, and 50 %**carbonate substituted apatite (cAp) that is rich in phosphorus (P). cAp is a complicated biomineral that contains**calcium, phosphate, carbonate, fluoride, and smaller concentrations of magnesium and sodium. When heat**treated, the carbonate content of carbonate apatite is lost as carbon dioxide, and the remaining mineral is called**hydroxyapatite (HAp). Unfortunately, both carbonate apatite and hydroxyapatite are not effective phosphorus**sources for animal feed, and the fluoride content should be reduced.**The goal of this Engage grant is to test chemical transformation methods to create useful, P-rich animal feed**from the HAp produced by Sanimax's incinerated livestock skeletons. Dissolution of HAp from heat-treated**bone mineral and crystallization of another mineral that is more easily absorbed during digestion, such as**monocalcium phosphate monohydrate (MCPM: Ca(H2PO4)2.H2O) or dicalcium phosphate dihydrate (DCPD:**CaHPO4.2H2O) are options for creating useful, P-rich feed materials from raw or heat-treated bone mineral for**Sanimax.
