S.E.D. ACTIVITIES31st MAR 2005 ÷ 31st OCT 2007

90 installations registered or authorised;20 installations fallen in Directive 96/61/EC

(I.P.P.C.);10 installations not compliant with Annex IIA

limits (waste gas and/or fugitive emission)Some activities not included in Annex IIB (Surface

cleaning, Manufacture of coating, etc)



THREE EXAMPLES OF INSTALLATIONS NOT COMPLIANT WITH ANNEX IIA

• Metal Coating (drying process, waste gas V.O.C. concentration > 50 mg/Nm3)

• Paper Coating (drying process, waste gas V.O.C. concentration > 50 mg/Nm3)

• Adhesive Coating (fugitive emission > 20% solvent input)

TARGET EMISSION (ANNEX IIB) NOT EQUIVALENT TO TOTAL EMISSION (ANNEX IIA)



Parameters ElectrocoatingSpray gun coating

(30% of rims)

Organic solvents input 20 t/y 85 t/y

Average organic solvent content

4,4% 35%

Average solid content 37% (170 t/y) 50% (120 t/y)

EX. 1 - METAL COATING

Activity: coating of rims - 8.000.000 rims/y (24 h/d x 230 d/y)

Before S.E.D. Annex IIA

ELV in waste gases (drying of coating)

115 mgC/Nm3 (e-coating)

73 mgC/Nm3 (spray gun)

50 mgC/Nm3



(waste gas emissions) 57 t/y +

[fugitive emission: 20% organic solvents input (85+20)] 21 t/y =

(total emission) 78 t/y V.O.C.


Total Emission Limit Value (Annex IIA)



Calculation of Target Emission (Annex IIB) Using Year 2004 Data

Total Mass of Solids: 120 + 170 = 290 t/y

Annual reference emission: 1,5 x 290 = 435 t/y

Target Emission: 25/100 x 435 = 108 t/y




Total emission Limit value Target Emission

78 t/y 108 t/y


Remarks• According to historical data provided by the operator, the total

mass of solids input in spray coatings is not constant

• High uncertainty in determining nominal capacity difficulty in determining the reference point for reduction

(Annex IIB): “The following scheme shall operate for installation for which a constant solid content of product can be assumed and used to define the reference point for emission reduction”



Activity: Adhesive coating onto metallic items before rubber application (dampers for automotive engines)

•3.400.000 items/y (24 h/d x 330 d/y);

•organic solvents input 33 t/y;

•adhesive solid content 34% (10 t/y).

EX. 2 - ADHESIVE COATING



Before S.E.D. Annex IIA

ELV in waste gases 65 mgC/Nm3 50 mgC/Nm3

Fugitive ELV 50% Solvent Input 20% Solvent Input

Mass Output in waste gases

15.5 t/y 8.5 t/y

Solvent Input 33 t/y 33 t/y

Fugitive emission 16.5 t/y 6.5 t/y




(waste gas emissions) 8,50 t/y +

[fugitive emission: 20% organic solvents

input (33 t/y)] 6,50 t/y =



Total Emission Limit Value (Annex IIA)



Annual reference emission: 4 x (10) = 40

Target Emission: 25/100 x 40 = 10 t/y V.O.C.


Total emission Target Emission

15 t/y 10



Remarks• Solvent free adhesive not available at the time of authorization;• The operator opted for:

enclosure of application boxes to decrease fugitive emission (2007);

replacement of old abatement equipment with a new regenerative thermal oxidizer

• Total Emission value comparable with Target Emission due to new V.O.C. abatement performance (waste gas N.M.V.O.C. concentration 20 g/Nm3 instead of 50 mg/Nm3).

EX. 2 - ADHESIVE COATING(Annex IIB): “the operator shall forward an emission reduction plan which includes in particular decreases in the average solvent content of the total input and/or increased efficiency in the use of solids to achieve a reduction of the total emissions from the installation to a given percentage of the annual reference emissions, termed the target emission”



• Coated Paper manufactured: 20000 t/y

• Organic solvents input 6600 t/y;

• Coating solid content 3150 t/y.

EX. 3 - PAPER COATING

Activity: production of paper for air filters (automotive engines) – coating with phenolic resin dispersed in methanol solvent




Before S.E.D. Annex IIA Authorization

ELV in waste gases 60 mgC/Nm3 50 mgC/Nm3 20 mg/Nm3

Mass Output in waste gases

195 t/y 155 t/y 65 t/y

Solvent Input 6600 t/y 6600 t/y



(waste gas emissions) 155 t/y +

[fugitive emission: 20% organic solvents

input (6600 t/y)] 1320 t/y =





Annual reference emission: 4 x (3150) = 12600

Target Emission: 25/100 x 12600 = 3150 t/y V.O.C.


Total emission Target Emission

1475 t/y 3150 t/y

Remarks• Solvent free resin not available at the time of authorization• The operator opted for:

replacement of old abatement equipment with a new regenerative thermal oxidizer;

recovery of methanol from impregnation machines



• Entry into force of S.E.D. in Italian Legislation only one year before first reduction step (31st OCT 2005 = T.E. x 1.5): very hard to lay out reduction projects with such a short time scale

• Enterprises Association and Operators found it difficult to deal with such a scheme, in particular because: products solvent free where not commercially available at that

time (coatings for plastic surfaces, adhesives…); very difficult to evaluate nominal capacity for certain activities:

which is the starting reference point?

CONCLUSIONS - 1



• Italian Legislation for air pollution at that time concerned only with ELV in waste gases and their analytical monitoring, not with management plans

• The ELV that Local Competent Authority used to set in permits were usually lower than those set in Annex IIA of S.E.D. many installation already complied with Annex IIA

CONCLUSIONS - 2
