Specific to livestock and dairy operations, BioFiltro’s patented worm powered wastewater system catalyzes the digestive power of worms and microbes to remove 70 – 99% of total nitrogen, phosphorus, ammonia, and total volatile solids from liquid manure. Our systems are designed to receive water as soon as it is discharged from the facility and, through a continuous intermittent batch process, we irrigate our systems for 2-5 minutes every thirty minutes and, within 4 hours, treated water flows out.

After years of third party research at dairies it was found when BioFiltro is installed upstream of lagoons we prevent solids from arriving to the lagoon and thus prevent the formation of methane and other green house gases from occurring. As such, our system enables farmers to achieve nutrient management plans, reduce your land application area, and/or increase your herd size while generating up to 8 carbon credits per milking head per year.

In 2020, our the carbon avoidance impact of our dairy liquid manure system at Royal Dairy in Royal City, Washington was verified on Verra’s Verified Carbon Standard. As such, the carbon credits generated through our system were able to be sold to a global CPG company as part of that Company’s pledge to lower their dairy carbon footprint.

Effectively, BioFiltro provides a nature based, non-combustion based climate smart solution for the dairy industry to achieve its net zero commitments.

The BioFiltro BIDA Wastewater Treatment System

Sabina Dore, Steve Deverel, Andrés Iacobelli, Matías Sjögren

At Royal Dairy, the first lagoon stores liquid manure after it has gone through a series of solid separators and before it has been sent to our BIDA System. The second lagoon is what stores our treated effluent. The difference is our four hour treatment that prevents tens of thousands of metric tons of CO2 equivalents avoided from forming each year from this one lagoon. Imagine the impact scaled up when BioFiltro treats more than just the 6,500 milking head at Royal Dairy.

"Our research showed that [BioFiltro's] vermiculture dairy manure technology reduces atmospheric nitrogen losses by 90%. After studying the microbiology, we now know that denitifiers take various nitrogen compounds and convert them to atmospheric nitrogen (N2). Great technology"
