Air emissions

Α+ | A-

Dust

Dust is a major industrial pollutant of the environment. At cement production plants the major source of dust emission is the production process. Fugitive dust is also created from transportation of materials.

Continuous monitoring of fugitive dust emissions is not possible. TITAN Group is implementing a program of periodic measurements for fugitive dust in order to safeguard the health of its employees as well as to reduce the impact on areas nearby. Further care is taken to ensure the proper maintenance and optimal functioning of machinery and equipment as well as the rigorous application of rules covering the transport of materials both within and beyond the plant site.

Total dust emissions in 2010 were 1,866 tons and specific emissions were 153.6g/ton clinker.

Taking into account the new acquisitions, equity changes and new kiln lines becoming operational in 2009, a revised target of 95g/t clinker was set in 2009 to be achieved by year 2015.

An increase of 10% in Group dust emissions from cement plants was recorded compared to 2009. The unusually frequent startups and shut downs of plants throughout the year prevented the optimum operation of the plants and relevant equipment for dust control creating this unfavorable side effect.

TITAN Group has invested heavily in new technologies to reduce its air emissions footprint during the last years. Kiln electrostatic filters (ESP) were either upgraded to hybrid filters or completely replaced with bag filters (at Kamari, Patras and Zlatna Panega plants). Further upgrades have been approved and will be implemented in the next years at the Alexandria, Beni Suef and Roanoke plants. Efforts for proper maintenance of the existing dust control equipment are also intensified, ensuring that our targets for limiting specific dust emissions to
95 g/t clinker by 2015 will be achieved.

ΝOx

Combustion at high temperatures leads to the creation of ΝOx. Scientific studies have indicated that ΝOx emissions lead to the creation of acid rain and smog.

In 2010 TITAN’s ΝOx emissions were 22,561 tons while specific emissions were 1,857g/ton clinker. As with dust, these emissions were within the limits stipulated in the environmental terms of the operating permits.

A revised target of 1,670g/ton clinker on ΝOx emissions, or 45% reduction compared to 2003, was set in 2009. The target year to achieve this is 2015.

SOx

The presence of sulphur (S) in raw materials is the primary cause of SOx emissions which have been directly linked to the appearance of acid rain. It is therefore important to keep these emissions as low as possible.

In 2010 SOx emissions were 2,567 tons while specific emissions were 211.3g/ton clinker. For yet another year, at many Group plants SOx emissions were negligible, while in all cases they were far lower than those allowed in the environmental terms of the operating permits.

Taking into account the new acquisitions, equity changes and new kiln lines becoming operational in 2009, a revised target of 240g/t clinker was set to be achieved by 2015. Having already reached a good level of performance in respect to SOx emissions, we aim to retain and even improve further this performance level.
