The contribution of mechanical and semi-chemical pulping to total VOC emissions in Europe is significant
European Commission
VOC emissions from the mechanical pulping process are the most significant air emission from pulping processes

The project will be a continuation of earlier work carried out in the VOCless pulping –Life Project (Life 06 ENV/FIN000201)

The main VOC emission sources of a waste water treatment plant will be piloted by applied abatement systems
Meehanite will act as beneficiary and coordinator between The Commission and the project partners

Introduction to theaims and organizationof the project
The conclusions, expected outcomes, and schedule of the project
Introduction to the technologies used in the project
The mass balances and VOC load of the waste water treatment plants will be analyzed, summarized and reported
Analysis of VOC emissionsfrom all waste water treatment unit processes
Process parameters and VOCemissions concluded as function
Performance of all three cleaningsystems reported
Reported findings serve as guide to system selection and design
There will be three main outcomes of the project
Measurement of VOC effluents and VOCBalance at Anjalankoski Pulp mill (xx kg/product ton = VOC load)
Combination of previous Life project results with this Life project resulting in total VOC balance in mechanical pulping
Conclusion report: “Abatement of VOC Loadfrom Waste Water Treatment in MechanicalPulping”
The report will outline the occurrence and dissipation ofVOC compounds in each stage of waste water treatment
The report will present calculations of the cost efficiency ofthe piloted technologies in waste water VOC abatement
Regenerative Catalytic Oxidizer (RCO)
Biofilter
UV filter
The project began in 2010 and is scheduled to be completed in 2013
In conclusion, the VOC control technologies will reduce waste water treatment plant VOC emissions by 90-95%
Stora Enso Anjalankoski pulp mill
VOC waste water effluents reducedby 0.4 kg VOC/t pulp
The result will be a 150 ton reduction in the annual 400 ton VOC emissions of the Anjalankoski mill
