New Partnerships to Develop BioFiltro in the Southwest

BioFiltro is partnering with Dairy MAX and New Mexico State University to install two pilot units at dairy farms in New Mexico and Texas to treat a portion of their liquid manure. These pilots will be operating throughout the year 2024. With these demonstrations, BioFiltro hopes to prove to this new region that vermifiltration effectively removes solids and nitrogen from liquid manure.

Research & Development

Fanelli Dairy Wood Media and Drainage Basin Tests

Fanelli Dairy Wood Media and Drainage Basin Tests

Guillermo Tagle, BioFiltro’s VP of Product, has begun testing new BIDA filter medias. The experiment includes our standard filter of pine wood chips as a control, as well as pistachio shells, walnut wood chipped, and walnut wood ground. The overall goal is to identify alternative medias or byproducts that reduce BIDA construction and filter replacement costs, while also boosting sustainability by using low-value materials that are otherwise wasted.


Over 200,000 square feet of worm beds coming soon to Moxee Dairy in Washington state. It’s no small feat, but this cool time-lapse video from A&K Construction makes it look easy!
