                        N-Viro Announces Rights Offering

Toledo,  Ohio,  March  22, 2004 -N-Viro International Corp. (OTC Bulletin Board:
NVIC:OB)  announced  today  that  its  Board  of Directors has approved a Rights
Offering  for the beneficial owners of its Common Stock.  The Company will issue
one  Right  to  purchase one share of Common Stock, for each ten shares of stock
beneficially  owned.  The  Rights,  which are being issued without registration,
will  be non-transferable and exercisable only by the beneficial owners in whose
names  they  are  issued.

Phil Levin, Chairman of N-Viro's Board of Directors said, "In view of the recent
private  placement  of Common Stock and the conversion of certain debt to Common
Stock, the Board wanted to give an opportunity to our existing beneficial owners
to  maintain,  generally,  their percentage of ownership if they elect to do so.
We  will  be  filing  a registration statement for the Common Stock to be issued
upon  exercise  of  the  Rights  (which  will  not  be  exercisable  until  the
Registration  Statement  is effective) and the exercise price will be set at the
time  of  effectiveness.  Any proceeds received would be used to further improve
the  balance sheet, and to implement new marketing tools and expand research and
development."

N-Viro  International  Corporation  develops  and  licenses  its  technology  to
municipalities  and  private  companies.  N-Viro's  patented  processes use lime
and/or  mineral-rich, combustion byproducts to treat, pasteurize, immobilize and
convert  wastewater  sludge  and  other  bio-organic  wastes  into  biomineral
agricultural  and  soil-enrichment  products  with  real  market  value.  More

The  Company  cautions  that  words  used  in  this  document such as "expects,"
"anticipates,"  "believes"  and  "may," as well as similar words and expressions
used  herein, identify and refer to statements describing events that may or may
not  occur  in  the  future. These forward-looking statements and the matters to
which  they  refer are subject to considerable uncertainty that may cause actual
results  to  be  materially  different from those described herein. For example,
while  the  Company believes that trends in sludge treatment are moving in favor
of the Company's technology, such trends may not continue or may never result in
increased  sales  or  profits  to  the  Company  because  of the availability of
competing  processes.
