A no BS answer to the world’s massive manure problem Low-cost chemical process quickly converts dung to odorless, sterile fertilizer powder that can be stored without fear of contaminating soil or water.

Paulee CleanTec, which holds patents for ecofriendly management of human and animal waste, recently installed a demo BioLizer system at a kibbutz dairy farm. “We can convert half a ton of fresh animal manure into odorless organic fertilizer in one hour,” says CEO Ilan Levy. “If you have 300 dairy cows, they generate a ton of liquid waste every hour. This is equivalent to wastewater from a town populated with 40,000 people.”
