Solution 3: polysius® fuel substitutionSubstituting the use of fossil fuels in your cement plant by 100 %

12 | 23.05.19 | Dr. Luc Rudowski | Grey2Green – heading toward the polysius® green cement plant

Biggest potential for clinker factor reduction

70 % CO2 reduction compared to clinker

Significantly decreased production costs

Maximum leverage of local resources

binder

Solution 4: polysius® activated clayReducing the clinker factor of your plants down to 50 %

Cost impact of sustainable development in cement business

Is it worth the CO2 reduction?

Viaduc de Millau (France) 2,460 m long, 343 m high, 127,000 m³ concrete

3 Mio. € additional costs i.e. 0.8 % price increase for the bridge (400 Mio. €)

Residential house 17.4 t cement, ~ 58 m³ concrete

1,350 € additional costs i.e. 0.5 % price increase for a residential house (250 k€)

If the cement price doubles…

… the price for a residential house would increase by 0.5 %

… the price for a bridge would increase by ~1 %

Our vision.
