Project objectives
16 to 19 MW of electricity production
Maintain the mill competitivity
Modernise the steam production equipements:
§ Boiler and flue gas treatment
11
![Page 12: Cogeneration Projet - PAPTAC · Cogeneration Projet Presentation to the PAPTAC Steam and Steam Power Comity By René Hamel, Eng. ... • Turbogenerator: March 25th, ...](https://reader031.fdocuments.in/reader031/viewer/2022022507/5aca46cb7f8b9a5d718e095c/html5/thumbnails/12.jpg)
Project objectives(cont.)
Improve the environmental performance of the mill:
§ Elimination of the bunker C consumption
§ Reduction of the greenhouse gas production
§ Paper sludge valorisation
Contribute to the provincial efforts to valorise 60% of theprovince valorisable residues before the end of 2008
§ Construction and demolition residues are burned ratherthan landfilled

7. SummarySustainable development project
1) Greenhouse gases emission reduction (83,000tons of CO2 eq./year equivalent to 18,000 cars)
2) Reduce sludge, construction & demolitionresidues landfill (1200 metric tons/day)
3) Reduce bunker C consumption by more than30,000,000 litres/year (200,000 barrels/year)
4) Job creation in the recovery, treatment andtransportation of the combustibles
5) Green electricity production
