Amendment-free sludge composting

A composting system for promoting aerobic microbial activity in a composting bed. The system includes at least one composting bay for receiving composting material and an agitator for aerating and displacing composting material as it travels through the composting bay. Compost produced by the system is used in place of traditional woody amendment material for mixing with incoming material to be composted.

System and process for reducing PFAS and microplastics in biosolids using hydrodynamic cavitation and foam fractionation
12291492 · 2025-05-06 · ·

A system for reducing particles from biosolids, comprising a storage tank for holding biosolids and an inlet pipe. The inlet pipe delivers biosolids from the storage tank to a screener and then to a percent solids meter. The percent solids meter measures the solid content in the biosolids and sends a signal to an electronic solenoid valve to control water content of the biosolids introduced to the system. A first venturi hydrodynamic cavitation to create vacuum bubbles in the biosolids. A mechanical hydrodynamic cavitation device operably connected to first venturi hydrodynamic cavitation, wherein the mechanical hydrodynamic cavitation device creates vacuum bubbles in the biosolids.

System and method for automatically generating organic compost from waste

Various embodiments are described herein for an apparatus that implements one or methods for producing compost. The method may include receiving waste in a composting apparatus, the waste having a first moisture content; pre-treating the waste to produce pre-treated waste; storing the pre-treated waste into a storage chamber for a pretreatment time period to produce stored waste; and composting the stored waste in a compost chamber to produce a batch of output compost having a second moisture content, wherein the second moisture content is less than the first moisture content.

WASTE DISPOSAL METHOD AND COMPOSTER
20250257015 · 2025-08-14 ·

The present application provides a waste disposal method that is applied to a composter including a storage cavity. The waste disposal method includes performing a first composting operation in response that first kitchen waste has been added into the storage cavity. Once the first composting operation is stopped, an internal environment of the storage cavity is adjusted to meet a composting condition of the first kitchen waste by performing an environment adjustment operation on the storage cavity according to a first time interval.
