Table 2. Substitution scenario's for each of the five wastes in clinker kilns

How to read this table:

For example, one tonne of industrial sludge would on average replace 250 kg of petcoke (fossil fuel) and 270 kg of raw materials.

Adding a tonne of fluff would on average replace 650 kg of petcoke and 120 kg of raw materials etc.

  Petcokes

1. Solvents & Waste oils 0,88 -0,01
2. Paint & Ink (residues)

0,44 0,18
3. Sludge 0,25 0,27
4. Filtercake 0,14 0,24
