Lagoon-Eliminating Waste Infrastructure for Dairy, Hog, and Cattle Operations

​

An aerobic livestock waste-management system that replaces conventional manure lagoons with controlled biological processing and converts high-liquid livestock waste into stable, high-humus compost.

​

Overview

​

Hamilton-White Composting Technologies (HWC) is developing a next-generation aerobic waste-management system designed for modern livestock operations. The technology builds upon a U.S.-patented system originally issued in 1995, subsequently constructed, operated, and tested under real-world conditions. HWC is now applying that technical foundation to a modernized commercial system engineered to directly process the high-liquid waste streams generated by today’s hog, dairy, and cattle operations.

​

HWC is designed to replace conventional manure lagoons with controlled, infrastructure-scale aerobic processing. Rather than storing livestock waste for extended periods and managing it as an ongoing environmental and operational liability, the HWC system processes the waste stream as part of the facility’s normal operation, reducing environmental exposure, improving biosecurity, stabilizing nutrients, and producing a consistent, beneficial compost output.

​

What the System Does

​

• Directly processes high-liquid livestock manure and effluent without requiring solids separation or extensive pre-treatment

• Uses controlled aerobic, thermophilic biological processing within an enclosed operating environment

• Eliminates the need for conventional manure lagoons within the HWC waste-management process

• Produces stable, pathogen-reduced, high-humus compost without requiring a separate compost-finishing stage

​

The system is designed for durability, serviceability, and practical on-farm operation.

​

What This Means for Livestock Producers

​

Dairy Operations

• Eliminates dependence on conventional long-term lagoon storage and its associated operational and environmental risks

• Directly processes high-liquid dairy manure and effluent as part of the facility’s ongoing waste-management operation

• Converts manure management from a recurring storage and disposal challenge into controlled, predictable infrastructure producing a beneficial compost output

Hog Operations

• Replaces conventional lagoon storage with controlled aerobic processing of high-liquid hog manure and effluent

• Supports improved farm biosecurity by reducing prolonged exposure to stored manure and associated waste-management risks

• Builds upon prior HWC testing in which thermophilic processing demonstrated destruction of the PRRS virus under tested operating conditions

Cattle Operations

• Provides controlled processing of manure and high-moisture waste streams from cattle operations

• Reduces dependence on conventional manure storage, handling, and disposal practices

• Converts livestock waste into stable, high-humus compost suitable for beneficial agricultural, land-management, and turf applications

• Creates opportunities for beneficial reuse of finished compost within the livestock operation or through external markets

​

Across livestock sectors, HWC is designed to transform waste management from an ongoing storage, handling, and compliance burden into controlled, predictable infrastructure—while producing a beneficial compost output with potential economic value.

​

Environmental and Operational Benefits

​

By replacing long-term anaerobic manure storage with controlled aerobic biological processing, HWC is designed to substantially reduce the conditions responsible for methane generation in conventional lagoon systems. Controlled thermophilic processing also reduces odor, stabilizes organic material and nutrients, and supports pathogen reduction through sustained biological activity and elevated operating temperatures.

​

Participation in environmental or carbon markets may be possible as a secondary outcome, depending on verification pathways and deployment context.

​

Proven Lineage, Modernized Design

​

The technological foundation of HWC was developed under U.S. Patent No. 5,405,780, issued in 1995, and subsequently incorporated into operating systems that demonstrated sustained thermophilic aerobic processing under real-world conditions. Today’s HWC system builds upon that demonstrated foundation with updated engineering, process controls, and system architecture designed specifically for modern commercial livestock operations.

​

• Direct processing of the high-liquid manure and effluent streams generated by modern livestock facilities

• Scalable reactor and facility configurations designed for commercial livestock production

• Modern PLC-based monitoring, process controls, and operational oversight

• Practical system operation, serviceability, and maintenance in agricultural environments

• Updated engineering designed to support repeatable manufacturing and large-scale commercial deployment

​

Development Status

​

HWC has advanced beyond the conceptual stage. The foundational technology was patented, constructed, operated, and tested under real-world conditions, establishing the technical basis for the current development program.

HWC is now completing the engineering required to translate that foundation into a modern commercial system designed for today’s livestock operations. The next phase includes fabrication of a transportable full-scale prototype incorporating modern PLC-based monitoring and process controls, followed by field operation and third-party performance validation at commercial livestock facilities.

This validation program is intended to document system performance under current operating conditions, support final commercial engineering, and provide the technical and operational data required for initial customer deployments and subsequent manufacturing scale-up.
