         HEADWATERS ANNOUNCES PURCHASE OF N-VIRO'S JOINT VENTURE PARTNER

TOLEDO,  OH, FEBRUARY 24, 2004 - HEADWATERS INCORPORATED (NASDAQ: HDWR) of South
Jordan,  Utah  has  recently  announced  that  it  has entered into a definitive
agreement  to  purchase VFL Technology Corporation of West Chester, Pennsylvania
subject  to  due diligence.  VFL Technology and N-VIRO INTERNATIONAL CORPORATION
(OTC  BB/NVIC.OB) jointly own Florida N-Viro L.P, which has the exclusive use in
Florida  of  N-Viro's patented pasteurization and stabilization technologies for
the  treatment  of  organic  wastes  using  mineral  byproducts  including  coal
combustion  byproducts.  Florida N-Viro operates from its Ft. Meade and Volusia,
Florida  facilities.

Under  the  terms  of  the agreement, Headwaters will acquire 100 percent of VFL
Technology  stock  in  a  transaction  valued at approximately $29 million.  The
acquisition complements the coal combustion product management operations of ISG
Resources,  Headwater's  wholly-owned subsidiary.  ISG Resources is the nation's
largest manager and marketer of coal combustion products - with approximately 20
million  tons  of  CCPs  from  115  power  plants  under  contract.

N-Viro  International 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 information about N-Viro
International  can  be  obtained  by contacting the office or on the Internet at
www.nviro.com  or  by  e-mail  inquiry  to  info@nviro.com.

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.
