Just read an article, "Technology Creates Really "Green" Ink
-- New Process Enables 100 Percent Recover from Hazardous
Sludge," out of "The P2 Alert," Autumn 1995 issue (Tennessee
Division of Pollution Prevention Environmental Awareness).
Thought it might be of interest to the Printech group.

"Thanks to the ingenuity of Knoxville inventor Frank Prasil,
printing ink residue at lithographic print shops can be
completely eliminated from the waste stream and used to
formulate quality ink.

Prasil has discovered how to change ink sludge from
lithographic printers, a gooey hazardous waste, into high
grade ink. In addition to being economical and
environmentally positive, the ink is rich in pigment. Even
compared to ink manufactured form virgin raw materials,
recycled ink generated by this process has superior printing
qualities, generates less process waste, and prints better on
recycled paper.

The process, know as Lithographic Ink-Waste Recovery
Technology (LIRT), recover 100 percent of the waste sludge,
composed o foil, oxide pigments, solvents and acid wash
waters. Lithographic printers currently incinerate more than
60 million pounds of this ink sludge. Recovery of usable
components occurs with no solid, liquid or gaseous emissions
to the environment.

The waste ink which once represented a disposal and
reporting liability for printers is now a $2000 per barrel asset.
In addition to the money savings this process represents, it
also conserves a great deal of natural resources. Prasil
estimates that his ink recovery system can save an equivalent
of 560 million cubic feet of natural gas and 660,000 barrels of
crude oil, and can reduce air pollution by 3,780,000 tons. The
ink recovery also uses 98.5% less energy than manufacturing
ink from virgin raw materials. European countries, which lack
the richness of raw material resources of the United States,
could prove an eager market for LIRT ink.

The inventor is currently working to secure patent rights and
has submitted a NICE3 (National Industrial Competitiveness
through Energy, Environment and Economics) grant proposal
to the Department of Energy, in cooperation with the
University of Tennessee Center for Industrial Services
(UT-CIS) and the Tennessee Department of Environment and

If you have an interest in trying the LIRT ink or learning more
about the ink recycling process, contact Tom Dolar at the UT
Center for Industrial Services in Nashville, 615/847-8007."

Re: FYI, "printech" subscribers

For those interested in recycling spent printing inks and solvents, I have the following information. The Mobile Printing Ink
Reclamation/Recycle System (MRS)/The Ink Company offers an on-site printing ink recycling system. They dispacth a mobile
trailer and equipment to the customer's site. The low VOC emission system reclaims/recycles spent letterpress ink via fitration and
centrifugation. The Ohio EPA reviewed a March 1992 request by Earl J. Estopinal, Synergy Resources Company, consultant to
MRS/The Ink Company, for setting-up recycling operations in three locations in Ohio. The Agency determined that the proposed
activities did not require an Ohio hazardous waste permit, provided certain conditions were satisfied.

MRS/The Ink Company began an on-site printing solvent recycling program in 1995. A distillation process is used.

The above information was recently confirmed through a conversation with Mr. Estopinal. MRS/The Ink Company operates in 35
states. For more details contact Mr. Greg Pope, Operations Manager, MRS/The Ink Company;
