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.

Sanimax专门收集和回收农业食品工业的副产品。Sanimax是一家私人公司，于1939年开始运营。Sanimax目前管理着广泛的农业食品 ** 工业废物，并在加拿大和美国的16个地点利用它们生产有用的产品。一个大规模的废物是动物骨骼，这是畜牧业的副产品。干燥后，骨骼的骨含量约为50%的胶原蛋白和其他蛋白质，以及50%的富含磷（P）的碳酸盐取代磷灰石（cAp）。cAp是一种复杂的生物矿物，含有 ** 钙，磷酸盐，碳酸盐，氟化物和较低浓度的镁和钠。当热处理时，碳酸盐磷灰石中的碳酸盐含量以二氧化碳的形式损失，剩余的矿物称为羟基磷灰石（HAp）。不幸的是，碳酸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资助的目标是测试化学转化方法，以从Sanimax焚烧的牲畜骨骼产生的HAp中生产有用的富含磷的动物饲料 **。从热处理的 ** 骨矿物质中溶解HAp和在消化过程中更容易吸收的另一种矿物质结晶，如 ** 磷酸二氢钙一水合物（MCPM：Ca（H2PO4）2.H2O）或磷酸二钙二水合物（DCPD：**CaHPO4.2H2O），是从原料或热处理的骨矿物质中为 **Sanimax生产有用的富磷饲料材料的选择。
