Workers at cement maker AGET Heracles, majority-owned by France’s Lafarge, are seen turning on the connection allowing natural gas to power its plant in Volos, central Greece, yesterday. In a ceremony attended by senior government and company officials, workers switched over the preheating function of the plant’s production unit to natural gas. The cement company’s 2007-15 plan aims at making the plant more environmentally friendly by reducing its reliance on fossil fuel. According to Heracles Managing Director Pierre Deleplanque, the company is committed to making the plant one of the most environmentally friendly industrial units via its investment program. AGET Heracles has a market capitalization of some 403 million euros and is 89 percent-owned by Lafarge.
