## Abstract

[Object] To provide a solid fuel which comprises a binder, a form retaining agent and a vegetable oil-containing substance in a balanced manner, has a stable calorific value and suppresses the production of carbon dioxide. [Solution] A solid fuel formed from a mixture of a binder, a form retaining agent and a vegetable oil-containing substance, wherein the amount of the binder is 1 to 85 parts by weight, the amount of the form retaining agent is 1 to 55 parts by weight, and the amount of the vegetable oil-containing substance is 10 to 85 parts by weight based on 100 parts by weight of the mixture, and the mixture is molded.

## Claims

### Claim 1

A solid fuel which is formed from a mixture of a binder (component A), a form retaining agent (component B) and a vegetable oil-containing substance (component C), wherein the amount of the component A is 1 to 85 parts by weight, the amount of the component B is 1 to 55 parts by weight, and the amount of the component C is 10 to 85 parts by weight based on 100 parts by weight of the mixture, and the mixture is compression molded.

### Claim 2 (depends on 1)

The solid fuel according to claim 1, wherein the total amount of the components A and B is 15 to 90 parts by weight based on 100 parts by weight of the mixture.

### Claim 3 (depends on 1)

The solid fuel according to claim 1, wherein the amount of the component C is 10 to 80 parts by weight based on 100 parts by weight of the mixture.

### Claim 4 (depends on 1)
