Method of making straw briquettes
First Claim
1. Procedure for the manufacture of briquettes or pills for stoking and subsequently useable in a natural cycle in agriculture made of compressed stems from grain or straw or similar cellulosic waste material having a hydrous content up to 30 percent with admixed binding agent, compressing, by trace or piston pressing, at a pressure temporarily raising the temperature in the straw briquette to a range between 75°
- C. and 200°
C., characterized by mixing stems with straw or similar waste material from pulses and/or protein plants to be used as said binding agent, said compression in said temperature area together with said hydrous content of said cellulosic waste material causing coagulation of the protein in said binding agent to bind the briquettes to a stable form resistant to physical stress.

Abstract
Procedure for the manufacture of briquettes or pills for stoking made of stems from grain or straw or similar cellulosic waste material with the admixture of a binding agent. Compressing, principally by trace or piston pressing, at a pressure temporarily raising the temperature in the straw briquette to an area between 75° C. and 200° C., characterized by mixing stems with straw or similar waste material from pulses and/or protein plants to be used as binding agent.

8. Procedure for the manufacture of briquettes or pills for stoking and subsequently useable in a natural cycle in agriculture made of compressed stems from grain or straw or similar cellulosic waste material having a hydrous content up to 30 per cent with admixed binding agent, compressing, by trace or piston pressing, at a pressure temporarily raising the temperature in the straw briquette in a range between 75°
- C. and 200°
C., characterized by mixing stems with straw or similar waste material from pulses and/or protein plants to be used as said binding agent, said binding agent having a protein content between 30 g/kg and 40 g/kg and being added in an amount up to 10 percent, said compression in said temperature range together with the hydrous content of said cellulosic waste material causing coagulation of the protein in said binding agent to bind the briquettes to a stable form resistant to physical stress. - View Dependent Claims (9, 10, 11)
