Abstract
Abstract Organic waste material such as animal manure, spent mushroom compost, composted municipal wastes, sewage plant solids, and agricultural processing wastes are reclaimed and reusable by homogeneously mixing one or more of the organic wastes with a fly ash binder in weight ratios between about 20:1 and about 1:9. The reclaimed wastes are deodorized and useful as fertilizers, as agents for reclaiming coal mine wastes, and as support material for plants.

Claim 3
Dependent Claim
67 words
The deodorized fertilizer composition of claim 1 wherein the organic waste and the fly ash binder are in weight ratios ranging from about 3:1 to about 1:3 and the fly ash binder comprises between about 34 and about 48 percent by weight of silica, between about 17 and about 31 percent by weight of alumina, between about 2 and about 27 percent by weight of ferric oxide.
Claim 4
Dependent Claim
