Abstract
A method of processing a cheese processing waste stream generated in a cheese-making process, comprising: PA1 i) contacting a cheese processing waste stream with an anion exchange resin under conditions to allow negatively charged materials to be absorbed onto said anion exchange resin; PA1 ii) removing said anion exchange resin from said cheese processing waste stream and eluting said anion exchange resin with an aqueous solution of a lithium salt to produce an eluent; PA1 iii) concentrating said eluent to form a solid comprising a lithium salt and a lithium salt of a cheese processing waste; and PA1 iv) washing said solid with an organic solvent, dissolving said lithium salt and leaving said lithium salt of a cheese processing waste as a solid.
