Sludge Watch ==> Norampac spent pulping liquor (Dombind) now gasified in Trenton Ontario

[Maureen Reilly]

Sludgewatch Admin:

Some of you may remember the" Dombind: Road Binder".  In 1996 Domtar Trenton 
was providing the tailings from their liquid industrial waste pond ('spent 
pulping liquor" or "black liquor") to municipal road superintendents as 
'free' and 'environmentally friendly' dust suppressant.

The black stinking goo was liberally splashed all over rural roads, despite 
the evidence that it was causing elevated levels of dioxins on the roadways 
and ditches.  The stinky stuff got all over cars, shoes, pets, ... got 
tracked onto driveways, homes, carpets.  People brought their pets to the 
vet for cleaning.  Rare birds like the Eastern Loggerhead Shrike were found 
dead on the roadways that were Dombind spread.   Cows were infertile after 
drinking from Dombind laced farm ponds.

FINALLY ... after a long campaign by World Wildlife Fund, Sierra Legal 
Defense, Ontario Federation of Naturalists and a spirited cohort of 
concerned rural residents the filthy practice was banned.

Now..ten years later....Domtar Trenton has turned into 'Norampac'  and they 
are using the spent pulping liquor for fuel.


Does anyone have any data on the emissions?  Does anyone know what they have 
been doing with the spent pulping liquor for the past 5 years?  There was a 
rumour it was being sent to Pennsylvania to spread on farm fields.  Ghastly.

Norampac project goes commercial

The black liquor gasification project shared by Norampac and ThermoChem 
Recovery International(TRI) has moved from commissioning to full commercial 
operation.

Norampac's facility in Trenton, ON also recently completed air emissions 
testing, and is the world's first commercial, low temperature black liquor 
gasification system.

"This is an important milestone for the technology and for the Trenton 
mill," said JJ Davis, general manager of the facility. "We continue to be 
committed to spent liquor gasification at Trenton and are working with TRI 
to gain even more steam production and energy savings."

The project at Trenton uses TRI's low temperature biomass gasification 
technology to recover chemicals and energy from the spent pulping liquor the 
mill produces in the manufacture of corrugating medium.

The project is able to meet all of the mill's spent liquor requirements, and 
supplies cooking liquor and process steam back to the mill to support pulp 
and papermaking processes.
