                        TOLEDO AND N-VIRO RENEW CONTRACT
                        --------------------------------

Toledo, Ohio, September 7, 1999 - J. Patrick Nicholson, CEO and Chairman of
N-Viro International Corporation [NASDAQ/NVIC], announced today that Toledo and
N-Viro have signed a five-year extension of N-Viro's contract to manage the
N-Viro Soil(TM) facility located at the city's Bayview Wastewater Reclamation
plant.

Toledo has the option to renew the contract for five additional years. N-Viro
provides total management of all biosolids processed at the Toledo facility.

"The Toledo N-Viro Soil facility is now in its tenth year of operation and has
received numerous state and federal awards and recognition," Nicholson said.
"The Toledo facility is one of the most cost-effective `Exceptional Quality'
(EQ) facilities in the U.S. EQ is the highest standard of performance recognized
by the U.S. Environmental Protection Agency in the treatment of wastewater
residuals."

In addition to the Toledo operation, N-Viro co-owns two regional facilities and
provides operating, technical and marketing services to a number of public and
private licensees around the world.

According to Nicholson: "The Toledo facility serves as N-Viro's working model
for the training of both national and international licensees. Today, more than
75 publicly owned treatment plants are processing wastewater residuals using
N-Viro technology. The process pasteurizes disease-causing pathogens, fixates
metals, immobilizes nutrients to reduce pollution run-off and leaching of
waterways and ground water, and converts odorous sludge into a soil-like
product."

Annual production at the Toledo facility is approximately 50,000 tons of N-Viro
Soil. To produce this amount of material, it utilizes N-Viro's initial patented
advanced alkaline stabilization technology, which usually includes aeration to
achieve accelerated drying.

All material is sold or used by the city.

In addition to Toledo's advanced alkaline stabilization process, other N-Viro
accelerated-drying options include: "Bio-Dry," a patented process to add
mechanical drying in lieu of aeration; "Bio-Blend," a patented process to
co-compost yard wastes using N-Viro Soil as a reagent; a patented bulk drying
process currently being used by VFL Technology, Inc., at its Wilmington,
Delaware, N-Viro facility; and an English patent-pending process which utilizes
enclosed recycling with passive drying.

"All of these processes," Nicholson said, "offer unique operating options; and,
in every case, an `EQ' marketable product with multiple sales opportunities is
produced. Each ton of product is protected by a $5 million product insurance
policy underwritten by N-Viro."
