This is a jumbo download of the movie!
A willow feeder is a simple yet groundbreaking waste system that keeps human waste out of water systems entirely. Unlike composting toilets, it separates poop from urine and greywater, stores it for two years to eliminate pathogens, and then uses it as nutrient-rich fertilizer for willow trees. The result is cleaner rivers and oceans, safer pathogen management, and a low-cost, sustainable solution for any home or community.
The Willow Feeder Movie captures 14 years of design, testing, and real-world builds. You’ll see exactly how the system works, why it’s better than sewage treatment plants, and how you can build one yourself.
In the Movie You’ll See
• What a willow feeder is and how it differs from composting toilets
• Why conventional sewage plants pollute and how willow feeders solve the problem
• Step-by-step builds of the Cooper Pooper (indoor) and WilloWonka (outdoor)
• How to collect, store, and safely use poop as fertilizer
• Why willows are ideal for nutrient cycling and how to plant them
• Pathogen management that outperforms sewage treatment plants
• How to operate at less than 10% of the cost of conventional systems
• Ways to reduce chemicals and contaminants in greywater
• Bonus benefits like solving “peak phosphorus” and improving soil health
• Lessons from over a decade of field testing at Wheaton Labs
