An animal feed is provided that employs a substantially indigestible cation exchanger capable of binding ammonium cations and an acidogenic substance to acidify an animal's manure and thereby create ammonium cations that can be bound by the cation exchanger. The animal feed reduces ammonia emissions from manure produced by animals fed the animal feed compared to the emissions obtained from manure when an acidogenic substance is fed alone and compared to the emissions obtained from manure when a cation exchange capacity material is fed alone. According to another aspect of the present invention, a method of lowering ammonia emissions from manure is provided. The present invention also provides a method for reducing soluble phosphorus levels in manure and a method for reducing total phosphorus levels in manure. In a further aspect of the present invention, a method is provided that yields manure that may be used alone or in concert with other materials to act as a fertilizer having advantageous ecological properties. Another aspect of the present invention provides a method for reducing insect populations associated with manure.

Animal feed and methods for reducing ammonia and phosphorus levels in manure

A method of treating metal-contaminated spent foundry sand, or other industrial waste, by combining the sand with a sulfite to produce insoluble metal sulfur oxide complexes that do not leach from the sand. The treated waste may also be processed to reducing &ldquo;clumping,&rdquo; thereby rendering the treated waste appropriate for use in another industrial process.
