The Science Behind Econo Silo Composting
Econo Silo composting leverages a combination of established techniques to accelerate organic waste decomposition and produce high-quality compost:
1. Aerobic Composting: The enclosed system relies on aerobic microorganisms, which require oxygen to break down organic matter. Aeration systems continuously deliver fresh air to the composting material, ensuring optimal oxygen levels for microbial activity.
2. Temperature Control: Maintaining a consistent temperature range within the Econo Silo is critical for efficient composting. This is achieved through: * Insulation: The silo's structure is often insulated to prevent heat loss, promoting rapid decomposition. * Heating: In colder climates, supplemental heating may be used to maintain optimal temperatures. * Cooling: In warmer climates, cooling systems may be incorporated to prevent overheating and maintain the ideal temperature range for microbial activity.
3. Mechanical Mixing: Rotating paddles or other mixing mechanisms are used to ensure even distribution of air, moisture, and nutrients throughout the composting material. This prevents the formation of hot spots or anaerobic zones, which can hinder decomposition.
4. Bioaugmentation: To accelerate the composting process, microbial inoculants can be added to the Econo Silo. These beneficial microbes enhance the breakdown of specific organic materials and contribute to the overall efficiency of the system.
5. Moisture Control: Maintaining the appropriate moisture content is crucial for microbial activity. Sensors within the Econo Silo monitor and adjust the moisture level through automated water injection or evaporation systems.
6. Turn Over: While Econo Silos are designed for enclosed composting, some systems might require periodic turning of the composting material for even distribution of oxygen and moisture.
7. Compost Maturity Monitoring: Sensors track key parameters like temperature and CO2 levels to determine compost maturity. Once the material reaches a stable state, it is ready for application.
These techniques work synergistically within the Econo Silo to create a controlled environment that optimizes the composting process, resulting in high-quality compost and reduced environmental impact.
Econo Silo Systems: A Spectrum of Options
While the principle of enclosed composting remains consistent, Econo Silo systems are available in various configurations and sizes depending on the specific needs of the application:
