The use of some natural resources is still necessar y

Replacement of natural raw materials

• Origin: thermo-electric power stations fume desulphurization process

• Replaces: natural gypsum

Bottom ash

Material recovery in Sesto Campano

19

2016 data

• 4 % replacement of natural raw materials

• 25 % replacement of fossil fuels

More should need to be done

Goals are clear, technologies are very advanced, laws have been enforced, but…
