Monitoring emissions is a pre-condition for controlling and reducing environmental impacts from cement production. In 2012, the Sharrcem plant was the first company in the country to introduce independent continuous monitoring systems, operating 24 hours a day. This enables the company to closely monitor the emissions on a real time basis and take action accordingly. At the same time, it gives interested stakeholders regular, updated information on its performance. Sharrcem actually operates a 24-hour automatic continuous monitoring system (installed in March 2012) calibrated and certified by an independent party according to European Standards.
An overview of the types of instruments, points of installation and parameters being measured is presented in the following table
The data derived from the measured values is processed using the licensed software MEAC 2000. The processed values are presented in conformity with the legal requirements and are submitted regularly to the Ministry of Environment and Spatial Planning (“MESP”).
At cement plants, major dust emission sources are kiln stacks and open surfaces creating fugitive dust from the transportation of materials. From 2012 Sharrcem has been equipped with a 24-hour automatic continuous monitoring system that measures and records its emissions on a real time basis. After the new reconstruction of the bag filters in the kiln and raw mill, dust emissions have been reduced to largely below the limits (ELV) set by the environmental terms and conditions of both local and EU legal requirements.
The presence of sulphur (S) in raw materials is the primary cause of SOx emissions. Sharrcem`s Sox emissions are substantially below the limits (EV) set by the applicable local and EU regulations.
Combustion at high temperatures leads to NOx emissions. Scientific studies have indicated that NOx emissions may contribute to acid rain and smog. In 2012 Sharrcem’s overall NOx emissions were clearly under the limits (ELV) set by local and EU legislation, on a steady improving trend.
Sharrcem operates with a completely closed water system. Water is used for process needs, cooling of equipment, environment needs and sanitary needs.
Main sources of water supply to the Sharrcem plant are underground waters from wells opened within the plant area. There is no industrial waste water discharge; only sanitary water is discharged in two water outfalls in the plant.
Total water consumption by cement product is very efficient – 320 l water / t cement. A full hydro geological study has been prepared by external experts to provide the assessment of the hydro geological conditions of Sharrcem and its surrounding areas in order to:
• assure a sustainable use of the underground water abstracted from wells within the plant
• evaluate impact on the aquifers – maps and drawings
• verify zero effect by our operation
