    Abstract: Disclosed herein are methods for treating wastewater grit to inactivate any pathogens that are present in the grit and for forming a solidified material comprising wastewater grit such as a chemically bonded phosphate ceramic (CBPC). The CBPC may be utilized in methods for repairing depressions in a road surface that include applying the uncured CBPC to the depression in the road surface and allowing the CBPC to cure.

    Abstract: The invention relates to a method for producing an osteotropic bone replacement material from a starting material which substantially has portlandite, calcium oxide, aragonite; calcite and/or apatite. The starting material is introduced into an autoclave with a strontium, fluorine and/or gallium source, wherein when using a starting material which substantially has portlandite, calcium oxide, aragonite; calcite a phosphate source is introduced. In addition, H2O is added into the autoclave as part of a solvent and the pH value in the autoclave is set to a range above 7. Afterwards, the closed and filled autoclave is heated for at least 1 hour and then cooled. The osteotropic bone replacement material thus developed is subsequently cleaned from residues of the phosphorus, strontium, fluorine and/or gallium source. Furthermore, the invention relates to an osteotropic bone replacement material which substantially consists of apatite and in which strontium ions are incorporated into the crystal lattice.
