Abstract

The present disclosure provides a novel method for the production of a biomass composition from waste materials including the steps of evaluating the waste material for emissions related factors, treating the evaluated waste material with the additive composition to form a low emissions biomass composition and shaping the biomass composition into solid fuel formations. The present invention further provides an additive composition used in the treatment of the waste materials that comprises an emission sponge, a filler and optional BTU modifier. The treating step includes the steps of sizing selected waste materials, blending the sized waste materials with the additive composition formulated specifically for the waste material and forming the blended waste materials into solid fuel formations. The resulting biomass solid fuel formations produce lower emissions than typically produced by coal and may be combined with, or used in place of coal in coal burning structures and devices.

Claims

1. A method of producing a low emission biomass fuel composition from waste material comprising the steps of:

a. evaluating selected waste material and formulating an additive for use with the waste material that adjusts the emissions levels produced by the waste material to within a predetermined range;

b. treating the evaluated waste material with the steps comprising;

i. measuring and adjusting the moisture content of the selected waste material to a predetermined amount;

ii. coating the selected waste material with an additive formulated for use with the selected waste material, wherein the additive includes a predetermined amount of an emission sponge consisting of salt, sea salt, or combinations thereof;

iii. soaking the waste material at a temperature of at least 130 degrees Fahrenheit for at least one minute; and

,

iv. reducing the size of the coated and soaked waste material to form a treated waste material to not greater than one quarter inch in diameter; and

then,

c. forming solid fuel structures from the treated waste material.

2. The method of claim 1, wherein the additive further comprises a filler.

3. The method of claim 2, wherein the additive further comprises a predetermined amount of BTU modifier consisting of steel slag, iron powder, or, combinations thereof.

4. The method of claim 3, wherein the amount of BTU modifier is between 0.1% to 50.00% by weight, the amount of emission sponge is between 0.1% to 10.0% by weight, and, the amount of filler is between 0.1% to 6.0% by weight.

5. The method of claim 2, wherein the emission sponge is sea salt.

6. The method of claim 1, further comprising the step of shredding the selected waste material to a uniform size of not greater than one half inch in diameter.

7. The method of claim 2, wherein the amount of emission sponge is between 0.1% to 10.0% by weight, and, the amount of filler is between 0.1% to 6.0% by weight.

8. A method of making a low emission biomass fuel composition from waste material, comprising the steps of:

a. measuring the moisture content of selected waste material;

b. measuring the gas emissions levels of the selected waste material when the waste material is burned;

c. formulating an additive to be combined with the selected waste material and adjust the emissions levels to fall within a predetermined range, wherein the additive includes a predetermined amount of an emission sponge consisting of salt, sea salt, or combinations thereof, and a predetermined amount of BTU modifier consisting of steel slag, iron powder, or, combinations thereof;

d. sizing the selected waste material to a uniform size of not greater than one half inch in diameter;

e. adjusting the moisture content of the sized waste material to be between 12.0% and 25.0% by weight;

f. coating the sized waste material with the additive formulated for use with the selected waste material; and

g. soaking the sized waste material at a temperature of at least 130 degrees Fahrenheit for at least one minute.

9. The method of claim 8, further comprising reducing the size of the coated and soaked waste material to not greater than one quarter inch in diameter.

10. The method of claim 9, further comprising pressing the waste material having a diameter not greater than one quarter inch, into solid fuel formations.

11. The method of claim 10, further comprising coating the solid fuel formations with starch for product stabilization.

12. A low emission biomass fuel composition comprising;

treated waste material formed through the steps including

i. measuring and adjusting the moisture content of a selected waste material to a predetermined amount;

ii. coating the selected waste material with an additive formulated to adjust the emissions levels of the selected waste material within a predetermined range, wherein the additive includes an emission sponge consisting of salt, sea salt, or combinations thereof;

iii. soaking the waste material at a temperature of at least 130 degrees Fahrenheit for at least one minute;

iv. reducing the size of the coated and soaked waste material to a predetermined size; and

then,

v. forming solid fuel structures from the treated waste material.

13. The composition of claim 12, wherein the additive further comprises a filler.

14. The composition of claim 12, wherein the additive further comprises a BTU modifier, and wherein the BTU modifier is steel slag, iron powder, or combinations thereof.

15. The composition of claim 13, wherein the emission sponge is sea salt and the filler is soy flour.

16. The composition of claim 14, wherein the BTU modifier is steel slag.
