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

​

A sealed, aerobic composting system that replaces manure lagoons with controlled processing and converts livestock manure into a stable, usable product.

​

Overview

​

Hamilton-White Composting Technologies (HWC) develops sealed, aerobic, in-vessel composting systems designed for modern livestock operations. The technology is based on a U.S. patent issued in 1995, which was successfully built and operated, and has since been modernized to address today’s high-liquid manure streams from dairy, hog, and cattle facilities.

​

HWC systems replace open manure lagoons with controlled, infrastructure-grade processing that reduces environmental exposure, improves biosecurity, and stabilizes nutrients while producing a consistent compost output.

​

What the System Does

​

• Directly processes high-liquid livestock manure from barns

• Operates as a sealed, aerobic, thermophilic system

• Eliminates the need for open manure lagoons

• Produces stable, pathogen-reduced compost suitable for downstream use

​

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

​

What This Means for Livestock Producers

​

Dairy Operations

• Eliminates long-term lagoon management and associated risk

• Improves odor control and nutrient stability

• Converts manure handling from a liability into controlled infrastructure

Hog Operations

• Reduces disease vectors associated with open storage

• Supports improved biosecurity, including relevance to PRRS-impacted systems

• Replaces lagoon exposure with sealed, thermophilic processing

Cattle Operations

• Converts manure streams into a soil-building compost product

• Supports downstream use in turf, land management, and agricultural markets

​

Across all livestock sectors, the system replaces a cost and compliance burden with predictable, managed processing and a potential new revenue stream.

​

Environmental and Operational Benefits

​

By eliminating anaerobic manure storage, the HWC system avoids methane emissions associated with traditional lagoons. Sealed thermophilic processing reduces odor, stabilizes nutrients, and supports pathogen reduction consistent with established composting principles.

​

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 original reactor architecture was developed under U.S. Patent No. 5,405,780 (issued 1995) and demonstrated reliable thermophilic operation in real-world use. The current HWC system represents a second-generation modernization of that proven design, updated for:

• Higher-moisture manure streams

• Modern livestock production scales

• Farm-friendly operation and maintenance

​

Development Status

​

The foundational reactor system was successfully constructed and operated following issuance of the original patent. The current HWC design reflects updated engineering for modern dairy, hog, and cattle operations. Pilot deployments and third-party validation are planned as part of commercialization.
