DESCRIPTION FROM PRODUCT VENDOR:

The Earth Flow composting system has a Positive Aeration System that delivers high pressure air to the bottom of the compost pile. The Earth Flow also pulls the air from the headspace of the composting vessel and into a biofiltration system. This biofilter can either be pile-based on in-vessel.

SPECS:

MAINTENANCE: Maintenance costs estimated at 3% of capital costs annually.

POWER/water: The Earth Flow is designed for a general recipe of 2 parts carbon-rich bulking agent to 1 part nitrogen-rich feedstock by volume. For example, for the EF-20 system, the total capacity is 22 yards. The total volume of bulking agent would then be about 14 yards and 8 yards of food residuals or other nitrogen-rich feedstocks. On a daily basis, the EF-20 can receive up to about 1.4 yard/day of bulking agent at 14 days retention.

 

No wastewater discharge
