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.

Abstract: [Problem] To provide a solid fuel suitable for thermal power generation by making use of the fruit seed or press cake thereof of a plant which grows in large quantities in nature. [Solution] The solid fuel comprises a composition containing 70 wt % or more, on dry basis, of the fruit seed or press cake thereof of Ricinus communis, Triadica sebifera, Jatropha curcas, Brassica rapa L. var. nippo-oleifera, Plamae, Zea mays or Prosopis glandulosa (honey mesquito) and is hot compression molded.

Abstract: A solid fuel molded out of a mixture of wood pieces having a size of 1 to 25 mm, paper pieces having a size of 1 to 25 mm and thermoplastic resin, wherein the mixture contains 80 to 95 parts by weight of the total of the wood pieces and the paper pieces and 5 to 15 parts by weight of the thermoplastic resin, and the weight ratio of the wood pieces to the paper pieces is 20:80 to 90:10. The solid fuel which generates a stable amount of heat is manufactured by using waste wood, waste paper and waste thermoplastic resin in a well-balanced ratio.

Abstract: To provide a solid fuel which uses waste wood, used paper, a binder, a form retaining agent and a caloric augmentation agent in a balanced manner, has a stable calorific value, and suppresses the production of carbon dioxide. A solid fuel which is formed from a mixture of wood pieces having a size of 1 to 50 mm, paper pieces having a size of 1 to 50 mm, a binder, a form retaining agent and a caloric augmentation agent, wherein the mixture contains the wood pieces and the paper/natural fiber pieces in a total amount of 15 to 45 parts by weight and the binder, the form retaining agent and the caloric augmentation agent in a total amount of 55 to 85 parts by weight, has a weight ratio of the wood pieces to the paper pieces of 20:80 to 80:20, and is molded.
