Principles for using AF&ARM in Halyps (1) 1. Respect the waste Hierarchy • we don’t use in kiln if ecologically and economically better way of recovery is available • Specific requirements and needs from Greek waste mgt planning 2. Additional emissions and negative impacts on human health must be avoided • on a statistical basis, emissions into the air shall not be higher than those from cement production with traditional fuel – Lesser limits through co-incineration Law – Reduction of pollutants in Environmental Impact Assessment (EIA) 3. The quality of the cement product remains unchanged • the product should not have any negative impact on the environment as e.g. demonstrated with leaching tests Τσιμέντα Χάλυψ Halyps Cement Italcementi Group

Principles for using AF&ARM in Halyps (2) 4. Halyps Cement Company is qualified • Has good environmental and safety compliance track records and provide information to the public and the appropriate authorities - We are open, consistent with continuous communication – Open Doors • Has in place personnel, processes, and systems demonstrating commitment to the protection of the environment, health and safety - ISO 14001 and OH&S system : ex. Quality control, Procedures, adequate equipment, health records, committees, trained personnel, emergency teams, acceptance procedures • Assures that all requirements comply with applicable laws, rules and regulations - Audits from ELOT, dpts of ministry of Environment, Prefecture dpts, Port Police, internal, insurance banks • Capable of controlling inputs and process parameters required for the effective co-processing of waste materials - Use of Best Available Techniques Τσιμέντα Χάλυψ Halyps Cement Italcementi Group

Further Actions - Investments 1. New Closed Storages / Silos for Raw Materials • Coal/pet-coke silos (plan for 2008) • Five year plan for the total project 2. New bag-filter in the place of the Electro-filter Dust Limit from 100 mg/Nm 3 � 50 mg/Nm 3 (plan for 2008) • 3. New AF storage and feeding system (for CO2 reduction) • Animal meal, impregnated saw dust, chopped tires etc Τσιμέντα Χάλυψ Halyps Cement Italcementi Group
