Carbon footprint

Cement plants generate carbon dioxide emissions, thus contributing to the greenhouse effect and climate change. There are both direct and indirect emissions of carbon dioxide (CO2).
Direct CO2 emissions from the production of cement are attributed to:

  • “Decarbonization”, the process of transforming raw materials (mainly limestone) into clinker, the main component of cement
  • Fuel consumption, since all fuels burned in the kilns (coal, oil petcoke etc) create CO2 as a product of the chemical reaction between carbon (C) and oxygen (Ο2)

Indirect emissions of carbon dioxide are released during the production of the electricity required for the production of clinker and cement.

The ΤΙΤΑΝ Group is reporting total direct CO2 emissions related to its activities every year since 2003.
In 2009 total direct CO2 emissions from TITAN cement and grinding plants were 8.7 million tons. In 2009 reported emissions include emissions from on-site vehicle and mobile equipment are included.

Transportation of raw materials and products, and even personnel contributes to CO2 and other emissions generated by fossil fuels. A study measuring energy performance of TITAN’s main offices in Athens and identifying areas for improvement was conducted in cooperation with University of Athens to further reduce indirect impacts.

To take into account the changes in the equity held by the TITAN Group (in cement production and grinding plants) in 2009, CO2 emissions were recalculated for the period 1990-2008. The specific Group emissions were 672.6kg CO2/t product, based on equity held in 2009.

Considering that the target was initially set in 2006 and calculated on the basis of equity held by the TITAN Group then, we exceeded this target by reaching the level of 676.5kg CO2/t product calculated with the Group equity of the year that the target was set.

In the context of the Group’s continuing efforts to improve its performance and taking into account the new acquisitions, equity changes and the operation of new kiln lines in 2009, a revised target of 628kg CO2/t product was set for 2015.

The new target corresponds to a reduction of our CO2 emissions by 22% compared to 1990 and it is also 5% below the projected for 2015 CO2 emissions by WBCSD in the Roadmap to 2050.

Energy Consumption - “We have to measure it – to manage it”

Evaluating energy performance and reducing consumption requires good info-rmation on how, when, and where energy is being used. Collecting and tracking this information is necessary for establishing baselines and managing energy use. Understanding current and past energy use is how TITAN Roanoke Cement, US identifies opportunities to improve energy performance and gain financial benefits. In 2009 TITAN Roanoke Cement installed a real time energy monitoring system using a network of digital meters to monitor and track energy consumption and energy intensity for each process area of the plant. All metering data is available in a central database for plant management to review, plant energy team analyses energy trends during operation and shut downs to determine where and how energy improvement can be made. The energy monitoring system enabled the plant’s energy team to identify several energy savings opportunities, and in 2009 their cumulative efforts resulted in saving 10M kWh at a value of $490K.
