WastAway wins US patent for hydrolyzer infeed

WasteAway, a Morrison, Tennessee-based green tech company that converts municipal solid waste (MSW) into fuel, has won a U.S. patent for its hydrolyzer infeed, bringing the company’s total number of U.S. and international patents to 27.

The new hydrolyzer infeed patent, announced at theWasteExpo 2025 conference and exhibition, covers WastAway’s continuous feed device that injects pre-processed MSW into high-pressure hydrolyzers called Cellulators. These technologies transform MSW into clean, negative carbon footprint biofuels and other sustainable products in about 30 minutes, the company says, achieving 85 percent landfill diversion.

Last week, WastAway was awarded a U.S. patent for its entire waste-to-fuel process that covers the company’s full technology suite. 

“In the last two weeks, we have been awarded patents for our entire waste-to-fuel process and our hydrolyzer infeed technologies, enhancing our leading-edge vision and position in the marketplace,” says Mark Brown, CEO of WastAway. “We are thrilled to make this announcement at the world’s largest municipal solid waste conference.”

WastAway has boosted its brand and increased its marketing with recent exhibition appearances at WasteExpo in Las Vegas; Biogas Americas in Denver, Southeast Recycling Conference in Destin, Florida; International Biomass Conference and Expo in Atlanta and SWANA Annual Western Regional Symposium in Yosemite, California.

WastAway says it is poised for explosive growth in the coming years. Construction on two major waste-to-fuel plants is in the planning stages. One in Murfreesboro, Tennessee, that will divert 85 percent of the city’s trash from the Middle Point Landfill in an industrial area of the city’s south side.

The second is in Kern County California near Bakersfield. It too will divert 85 percent of the waste processed into renewable fuel and other beneficial products, WastAway says. These plants will cost an estimated $210 million to build and will process 400 tons of MSW a day each, according to the company.

That’s the carbon equivalent of removing 96,000 automobiles from the highway, WastAway says, eliminating 866 billion pounds of carbon from the air and adding 517,000 acres of forest land producing clean oxygen each year.

WastAway was founded in 2002 as a subsidiary of Bouldin Corporation, which began in 1959 as Bouldin & Lawson, a manufacturer of agricultural and horticultural machinery for the greenhouse and nursery industries.
