Sludge Watch ==> Natural Resources Canada - paper sludge to energy conversion

[Maureen Reilly]

Sludgewatch Admin:

Rural residents in Southern Ontario, Wisconsin, British Columbia, and 
countless other jurisdictions have been tormented with mountains of grey 
decomposing paper mill waste.  In Southern Ontario, Atlantic Packaging and 
Abitibi sludges have violated Ontario laws with leaching mountains of waste.

Outraged rural residents and their environment  have paid a terrible price 
for this 'waste diversion' strategy gone horribly wrong.

Pulp and paper sludge to energy conversion

ADI Limited

The Canadian Pulp and Paper mills generate a large amount of sludge from 
their operations (i.e. sludge from primary, secondary wastewater treatment 
and deinking process). Traditional solid sludge disposal methods of 
landfilling is becoming less attractive due to concerns about its adverse 
effects on the environment and increasing costs.

Other solutions are possible and using carbon-based sludge to produce heat 
and power offers one of the most interesting alternatives as it could 
simultaneously reduce the effect of the solid sludge disposal on the 
environment as well as fossil fuels consumption to produce the energy 
required by the mills operations. The Canadian pulp and paper industry 
already converts part of its sludge into energy but there is still a room to 
increase the adoption of this practice by making it more cost effective and 
efficient technology through technology improvement and development as well 
as optimum conversion system selection.

CETC-Varennes performed an opportunity analysis and technology assessment on 
the conversion of pulp and paper sludge into energy. An advisory committee 
formed by representatives of four major Canadian pulp and paper companies, 
PAPRICAN, École Polytechnique of Montreal, Environment Canada and Natural 
Resources Canada supervised the study performed by ADI Limited, an 
independent engineering firm.
