Abstract

Fuels used may be derived from existing waste streams such as animal wastes and streams of discarded or unwanted animal byproducts generated at animal slaughterhouses. A method of processing organic waste products into fuel includes homogenizing the waste products. The waste products are heated and pressurized. Water is removed from the waste products. Selected constituent of the waste products are separated from the waste products into a waste stream. The waste stream is blended with a fuel to form a bio-fuel mixture.

Claims

1. A method of processing organic waste products into fuel comprising:

(a) homogenizing the waste products;

(b) heating and pressurizing the waste products;

(c) removal of water from the waste products;

(d) separation of a selected constituent of the waste products from the waste products into a waste stream; and

(e) blending a fuel with the waste stream to form a bio-fuel mixture.

2. The method of claim 1, wherein the selected constituent is fats and oils.

3. The method of claim 1, wherein the selected constituent is proteins.

4. The method of claim 1, wherein the selected constituent is cellulose based products.

5. A method of processing waste products from biological sources into fuel comprising:

(a) homogenizing the waste products;

(b) heating and pressurizing the waste products;

(c) removal of water from the waste products;

(d) separation of fats and oils from the waste products into a first waste stream;

(e) separation of proteins from the waste products into a second waste stream;

(f) separation of cellulose from the waste products into a third waste stream; and

(g) blending a fuel with at least one of the first, second, or third was streams to form a bio-mixture.
