Organic waste reduction and biogas production system combined with hydrothermal carbonization with improved energy consumption efficiency

Abstract

Disclosed is a system for reducing an amount of organic waste and increasing biogas production, combined with a hydrothermal carbonization device having improved energy consumption efficiency. According to an aspect of the present invention, provided is a system for reducing an amount of organic waste and increasing biogas production, the system comprising: a storage tank configured to receive and store organic waste; an anaerobic digester configured to digest organic waste from the storage tank, digest organic matter, and produce biogas; a dewatering unit configured to primarily dewater organic waste discharged from the anaerobic digester; a hydrothermal carbonization device configured to receive and hydrothermally carbonize the dewaterd organic waste; and a filter press configured to secondarily dewater the hydrothermally carbonized product discharged from the hydrothermal carbonization device.
