Abstract
Abstract An absorbent composition for animal excreta and a process for making and using the composition including its decomposition is disclosed. The composition is made from dried, chopped corn stalks mixed with lime and an organic material having a density greater than the corn stalks selected from a group comprised of wood shavings, hulls of cereal grains, chopped soybean stalks, and chopped straw. A deodorizing substance may be added. The composition, when contaminated with animal excreta, decomposes rapidly into an organic soil.

Claim 1
Independent Claim
81 words
An absorbent composition comprising chopped corn stalks having a moisture level by weight less than 20%, lime, and an organic substance cut to be no larger than said corn stalks and having a density greater than said corn stalks, said organic substance for adding weight to said chopped corn stalks for said composition, said corn stalks comprising at least 50% by weight of said composition, said corn stalks being chopped into a distribution of lengths averaging between 13 and 38 millimeters.
Claim 2
Dependent Claim
81 words
An absorbent composition comprising chopped corn stalks having a moisture level by weight less than 20%, lime, and an organic substance cut to be no larger than said corn stalks and having a density greater than said corn stalks, said organic substance for adding weight to said chopped corn stalks for said composition, said corn stalks comprising at least 50% by weight of said composition, said corn stalks being chopped into a distribution of lengths averaging between 13 and 38 millimeters.
Claim 3
Dependent Claim
20 words
