Inland Empire Regional Composting Facility

The Inland Empire Regional Composting Facility (IERCF) was constructed under a Joint Powers Authority Agreement between the Inland Empire Utilities Agency and the LA County Sanitations Districts to manufacture exceptional quality compost that is good for: soil, plants, the environment, and public health. The fully enclosed co-composting facility processes a blend of green waste, dairy manure, and biosolids. Furthermore, this massive facility had the goal of being "completely nuisance fee," meaning the odor control of the facility was a key priority.

​

The IERCF biofilter represents one of the most notable and ambitious BacTee projects.

​

Following on the heels of the LACSD's extensive evaluation and testing of a myriad of biofilter technologies, the agencies made it clear to all design engineers working on the project that only the BacTee aeration floor system would be used to distribute air to the organic media (wood chips & compost) biofilter. At over 800,000 cfm, this was to be one of the largest biofiltration odor control systems in the US, if not the world, and odor control was to be given the highest priority due to the risk.
