Document Type and Number:
Japanese Patent JP2023007925
Kind Code:
A
Abstract:
To provide an organic matter recycling method and an organic matter recycling system that use biogas without separating carbon dioxide to produce liquefied petroleum gas and safely cultivate algae by using carbon dioxide, which is a residual component after the use of biogas.SOLUTION: An organic matter recycling method includes: a production process for producing biogas containing methane and carbon dioxide and a methane fermentation digestion liquid from an organic waste; a liquefied petroleum gas production process for producing a gas containing liquefied petroleum gas by using methane and carbon dioxide in the biogas produced in the production process as raw materials; a digestion liquid supply process for supplying the methane fermentation digestion liquid produced in the production process to an algae culture tank; and a carbon dioxide supply process for supplying, to the culture tank, carbon dioxide contained in the gas produced by consuming methane in the liquefied petroleum gas production process.SELECTED DRAWING: Figure 1
