Earth Flow™ Site-Built
America's Leading Industrial In-Vessel Composting System
To maximize the odor control and mixing power of the earth flow, we design hybrid systems that combine the earth flow with a secondary ASP. This design allows operators to get the benefits of the earth flow, while processing up to three times as much material with their system.
90% Emissions Control
Minimal Labor
Half the Footprint
50 Day Process
How It Works
Load inbound material directly into the Earth Flow and watch as it homogenizes your material, kick starting the microbial process and bringing material up to 60% moisture content. After one week in the earth flow, move material into a secondary ASP bay where emissions are further reduced, nitrogen is mineralized, and pathogens are destroyed. After this three to four week process material is ready for curing, screening and product sale.

Capacity + Economics
Our financing options can make the Site Built Earth Flow™ immediately cash-flow positive for qualified customers. System financing is available with monthly payments as low as $2,000.
Example cash-flow + savings from a Site-Built 7012 Earth Flow: monthly savings based on captured/avoided waste disposal costs of $65/ton and compost market value of $50/ton:
| Tons Per Month of Material Composted, 14 Day Retention | 153 | |||
| Monthly Avoided Disposal Costs, Compost Value, minus Operating Costs | $14,350 | |||
| Monthly Finance Payment 6 yr term @ 7.99% | -$2,405 | |||
| Monthly Cash Flow Including Finance Payment | $11,945 |
“With our previous turned windrow systems we had a hard time keeping up. That stress has been alleviated with our site built Earth Flow. The long-term investment in the system has a return on both labor and operating costs. I am no longer spending 16 hours a week in a skid steer and have the opportunity to spend more time in the field and greenhouse. We are also producing more compost than our old turned- windrow process, which helped us quickly transition into a no till farm.”
