Tiger
BioFilter
Nature's most powerful waste treatment system
About 2 billon people around the world do not have access to sanitation and 1.7 billion people live under water-stressed conditions. We've built the most eco-friendly, affordable solution with our Tiger Biofilter technology, eliminating 99% of fecal pathogens and creating reusable non-potable water.
About vermifiltration
Our Tiger Biofilter technology has rapidly scaled into one of the most widely-deployed natural, decentralized sanitation/sewage treatment technologies in the world. In just 4 years it has scaled to treat the waste of over 100,000 people. The technology uses a species of earthworms (known as Tiger Worms) with a natural filtration process to effectively treat fecal and sewage waste.
Worm-powered technology
-
The tiger worm (Eisenia fetida) is an earthworm species long known for digesting organic material
-
These worms thrive in moist soil, rotting vegetation, manure and fecal waste, consuming pathogens and converting the waste into gas and compost
-
Local subspecies are found in most parts of the world, especially in tropical climates
-
Worm ecosystem operates on self-regulating basis: population increases and decreases based on resources available

Vermifiltration compared to sewage treatment alternatives
Where we're working
A Scientific Approach with Independent Validation
Vermifiltration has become increasingly recognized as an effective waste-treatment system in academic research. We employ rigorous scientific testing of all products and deploy independent, third-party validation.
Hawai'i
Hawai'i has a massive sewage problem the world has never heard of. Nearly 90,000 homes discharge their waste—collectively over 50 million gallons daily—directly into holes in the ground (known as cesspools).
Our TBF system is the most affordable and effective solution compared to the alternative septic tank which costs between $10,000-$25,000.
In partnership with the Hawai’i Dept of Health, we are launching an ambitious initiative to use this system and solve the state’s sewage problems, with independent testing by the University of Hawai'i.

India
Treating waste generated by 100,000 people in India, in rural, peri-urban and urban settings.
All four products deployed across India.
0.5 MLD plant commissioned by city of Pune with 2 years of continuous operation with 100% of treated water reused for irrigation.
Continued expansion of all four products in municipalities, apartment buildings and factories, schools and homes.
A Proven Model for Scale
TBF Solutions creates local subsidiaries or launches joint ventures with in-country partners who have an established footprint and robust infrastructure. In 2020 we spun off TBF Solutions to scale in various locations.
