Tin · sensitising and passivation
10×
Tin consumption falls to a tenth
Tin is applied to the glass in two steps: sensitising and passivation. A comparable amount of tin remains on the mirror, while about 21 times less goes into the rinse water.

Tin · sensitising and passivation
10×
Tin is applied to the glass in two steps: sensitising and passivation. A comparable amount of tin remains on the mirror, while about 21 times less goes into the rinse water.
Platinum-group metals · activation
≈ 6×*
Superactivator contains a reducing agent as well as the platinum-group metals, so most of the metal is deposited on the glass and about 26 times less goes into the rinse water. The figure applies to lines using water-borne paint (the for green range).
* on lines using water-borne paint. On lines using two-coat solvent-borne paint, Superactivator reduces the dose by about 2.4×.
Silvering line
A mirror is made on a silvering line in seven steps. EGO 93 supplies the chemistry for four of them: sensitising, activation, silvering and passivation. The line stays as it is; only the concentrates in the tanks change.
Changeover
The changeover requires no investment in equipment and no rebuilding of the line. Only three things change: the concentrates, their dilution (as specified in the technical data sheet) and the nozzle maintenance routine. The pumps, nozzles, line speed and sequence of steps stay the same.
The for green range
Sensitising, activation, silvering and passivation, all from one manufacturer. The range uses the same concentrates as our Supersensitizer and Superactivator, together with MS silvering solutions.
The platinum-group metal saving is greatest on lines using water-borne paint.

Model mirror plant · 5,000,000 m² of mirrors a year
The amount of metal remaining on the mirror is comparable with today’s. What changes is how much metal the mirror plant buys, how much of it is washed away with the rinse water and how much sludge it produces.
−83%
Almost all of the carbon footprint of the metals purchased for sensitising, activation and passivation comes from the platinum-group metals. Using a sixth of the platinum-group metal dose therefore reduces this footprint by 83%. For tin, the reduction is 90%.
≈ 21×
The volume of rinse water does not change; what changes is the amount of metal the water carries away: ≈ 21× less tin and ≈ 26× less platinum-group metal.
≈ 27 t → ≈ 1.3 t
Tin dissolved in the rinse water is precipitated, and the sludge is dewatered, transported and landfilled. The less tin goes into the water, the less sludge there is. The figures show wet sludge per year.
Illustrative calculation: 28 t CO₂e per kg of primary palladium (IPA 2022); for illustration we have applied the same value to the whole mixture of palladium and ruthenium. Emission factors of metals vary by up to an order of magnitude depending on their origin, so we give ratios: whatever value is assigned to a gram of metal, the carbon footprint of the purchased metal falls by 90% for tin and by 83% for platinum-group metals.
