The Golden Days
• Do you remember when:
• Cement demand was high
• Competition was low
• Energy prices where stable
• Environmental regulations where minimal
• Investment money was
ready available $$$
• Claudius Peters remembers

Today
• Cement price is low
• Competition is high
• Energy price is high
• Environmental regulations are though
• Investment cuts eminent $
Claudius Peters solution:
• New cooler technology• Efficient = decrease energy
and fuel cost
• Closed system = environment friendly
• Short Return of Investment
