Innoventor Recycles Pig Waste for Road-Paving & Roofing Products
Innoventor, a St. Louis-based design-build company, using a grant from the U. S. Environmental Protection Agency, has engineered a device that recycles pig waste for durable road paving and roofing products. As reported Kristen Hinman in the November issue of The Atlantic, the company says the need for stinking manure lagoons can be eliminated, as can some reliance on fossil fuels.
The processing machinery is said to function much like a pressure cooker does, creating a certain temperature and pressure at which solid excrement is converted to bio-oil . At the same time, the wastewater is saved and can be converted into a liquid fertilizer.
Innoventor’s Swine-Manure-to-Energy unit appears to be odorless, reports hog producer, Rick Rehmeier, whose barn is being used for testing by Innoventor. He has 10,000 hogs that produce over 5 million pounds of excrement annually. Traditionally, most of this has gone to waste.
Rick Lux, an Innoventor engineer, said Innoventor could produce almost one pound of oil per pig each day. He adds the converted product can be used in the asphalt binder market.
Innoventor is not merely looking at pig excrement for material. It is looking at other forms of waste, including human excrement. On its website, Innoventor describes itself as a progressive, entrepreneurial design/build engineering firm diversified in five major industries. Our core competency is leveraging cross-industry experience and cutting edge technology to provide innovative solutions for our customers.
