Future Opportunity of Waste as Energy Source
Waste Management Hierarchy
ENERGY RECOVERY

• Cement kilns can use a variety of wastes as fuel

• Biomass
• Animal Waste
• Other

• Oil
• Tires
• Plastics

• Encouraged by new regulations in developed
  countries

• Economic and environmental related benefits

Cemex is already using Biomass Fuels

• CX uses forestry, agricultural, commercial,
  industrial, and household wastes as alternative
  fuels for its kilns

Cemex Germany Rüdersdorf Plant

• Rüdersdorf plant has a biomass gasification
  system assembled to the kiln

5
Rüdersdorf Plants Gasification Scheme

• The system consists of a circulating fluidized
  bed gasifier assembled to the kilns calciner
  its thermal capacity is 100 MW and accepts
  multiple residues as feedstock

Wind Power Projects

• CEMEX is also developing wind power projects.
• Currently, a 250 MW wind farm in Mexico is
  projected. It will help secure power to cements
  plants in Mexico and produce 600,000 tpy of CO2
  credits.
