Continuous emissions monitoring system
Beyond legislative requirements, the company voluntarily decided to establish and operate a Continuous Emission Monitoring System (CEMS), since the beginning of the plant operation.
Sulphur oxides emissions main stack
Nitrogen oxides emissions main stack
Dust emissions main stack
Sulphur Oxide and Nitrogen Oxide
Both Sox and NOx emissions are well below the limits defined in the Albanian legislation. SOx emissions are very low, due to their low concentration in fuels and raw materials. Based on the Continuous Emission Monitoring System installed and operating since December 2010, are presented below the annual average concentration emitted from the kiln stack. Emission levels in ANTEA Cement Plant refer to standard conditions: dry gas at a temperature of 273 K, and a pressure of 1 013 K.
There are two sources of dust in cement plant, respectively:
Point source dust is the total of the particulates emitted from the stacks (kiln, cement mill, coal mill, and cooler). Measured values show that the emissions are well below the limit. Measures on reducing
1. Point source dust emissions are presented as follows:
- Bag filters used and properly maintained in order to assure low levels of dust.
- Transportation done via covered belt conveyors
- Closed storages, etc
Ambient air quality
Noise level in the perimeter of the plant and quarries
Liquid effluent discharge
ANTEA monitors the quality of liquid effluents on a monthly basis, through accredited laboratories, and on weekly basis through internal quality checks. Surface water before being discharged is treated through decantation ponds to reduce suspended solids and oil and grease. The surface water collected in the decantation ponds is reused for dust suppression activities, reducing water consumption. The discharged plant surface water quantity is not measured. Waste water treatment facility is implemented and operates since the construction of the facility. The water discharged is measured via flow meters. There are no breaches in the thresholds/limits defined in the legislation. There are no significant impacts identified/reported from the discharge of waste water.
Environmental Management SystemOn July 2012 ANTEA Cement received ISO 14001:2004 certification. The system includes air emissions, quarries, landscapes, groundwater, wells and water waste, liquid and solid waste, natural resources & energy consumption, noise, etc. The system is audited and maintained annually for its compliance. The Plant establishes and maintains procedures to identify and handle the environmental aspects of its activities within the defined scope of the Environmental Management System. For this, ANTEA has established an Environmental Management Policy and Environmental Procedures (EP). The policy and the procedures cover the cement Plant and the Quarries of ANTEA Cement.
The areas nearby the Plant and associated quarries are open scrub lands being used partly for grazing, hunting and as a source of wood for heating. No protected zones have been identified in the vicinity of the Plant and associated quarries. Also, the areas within the radius of 1 km from the borders are not considered to be of exceptional ecological value, with habitats of similar composition and quality being found in the surrounding area. Scanning of plant and associated quarry areas for identifying possible high biodiversity zones is a continuous process and the latest scanning was performed in the second trimester of 2014 via “Integrated Biodiversity Assessment Tool” (IBAT) application. IBAT assessment has shown that there are no protected areas or areas of high biodiversity value within or adjacent to ANTEA quarry sites. The development of quarry management and rehabilitation plans for the ANTEA project was conducted as per ESIA (Environmental Social Impact Assessment) findings. The quarry rehabilitation plan has been considered as best practice from WBCSD/CSI, based on:
- Implemented quarry management plan before the quarry operation initiation
- Implementation of a rehabilitation plan before the quarry operation initiation
- Identification of the flora and endemic species of the region prior to quarry operation initiation
- Rehabilitation was conducted within the first year of Quarry operation
- Two Albanian endemic species were included in the quarry rehabilitation plan (Refer to pictures below)
- The first quarry in Albania to be exploited according to EU standards and fully compliant with the legislation
ANTEA “hydro-drilling” project has been initiated by Production Technology (PT) in March 2007 following a preliminary Study by ANTEA Geo-Team in cooperation with experts from Tirana University regarding the hydro geological conditions of Burizane Region. After a detailed study that lasted 9 months, the experts concluded that: “Based on the calculated Cement Plant needs (at maximum), the annual rate of pumping from the Borizan aquifer is hardly 3% of the total annual potential of the replenishment of the aquifer, i.e. the “fresh” water supply/recharge in the aquifer for the general area”.
Water Management practices
- Implemented water management system.
- Quality and quantity of withdrawn water from wells is monitored by independent accredited laboratories (although not a requirement from Albanian legislation)
- Monthly measurements of water levels in water drills to ensure sustainable water withdrawal.
- Implementation of closed water recycling system.
- Implementation of a well-defined network of flow-meters in order to identify and easily track possible water leakages.
- Monitoring water consumption by destination.
- There are no water sources significantly affected by the water withdrawal. ANTEA Cement recycles more than 60 % of the water used.
