ENVIRONMENT
In ecological aspect we are responsible and targeted. Our policy related to the environment is directed towards the social ecology, the relationship man - nature. We strive to protect and improve both the natural and social environment, creating conditions that meet the biological and social requirements.
Since June 2014 the enterprise is certified according to ISO 14001:2015 which proves our principles on the environment and its preservation.
The Environmental Requirements related to extracting alluvial material from the bed of the Danube are expressed in regulating the extraction through permitting regime according to the current regulations.
Extracting action and protecting the environment
Air
In many cities the industrial enterprises have a negative impact on the air quality and contribute to the presence of dust matter in it above legal limits. In the derived by us inert materials there is no process that affects in any negative way the air , - the enterprise has no facilities which separate mineral dust. The inert materials (sand fraction) are extracted and transported damp, which does not premise any spreading of dust.
Our ships have been modernized and meet all European Standards, which on its part guarantees minimum emissions into the environment.
Water, Soils and Earth Womb
Danube has a high water amount , as annually it superimposes tens of millions of tons of floating and bottom silt / sand, gravel, silt /. In periods of low level of the river, in drought and at a lower speed of the water there are prerequisites for the accumulation of alluvial deposits in some areas of the river. Their depositing reduces the depth in some areas, leads to occurrence of shoals and rapids, and slows the water flow. Consequently, the reduced section and patency of the river stretches has a negative impact on the navigation.
Significant amounts of sediments are deposited around the islands, especially in the sleeves between them and the riverbank. At high water levels there is a risk of backing up, increasing the erosion and flooding the coast due to the abrasiveness of the water with sediments.
Danube is dynamic , - rapidly and permanently altering its morphological structure, continuously washing away and flooding the formed islands as a result of which the deep zones move regularly, so the dredging operations in it are important for the maintenance of its hydrological regime.
The extraction of alluvial deposits from the bed of the Danube improves the navigational routes and contributes to free fish migration. The extraction of materials leads to improved conductivity of the river , prevents flooding of its banks and increases their erosion.
The extracting activity performed by us is in the lower reaches of Danube, where the water speed is lowest and where the most common water levels are formed. As a consequence, vitally important, positive effect on the extraction of inert materials is also the subsequent aeration of the water, which occurs as a result of the processes of scooping, extracting and mixing the sediment deposits in the river.
Protected Zones and Biodiversity
The preliminary identification of the section of extraction ensures that the deployment of vessels does not disturb the peace and does not affect the habitats of protected species.
We use the safest and most environmentally friendly method of removing the alluvial materials which technological process is carried out by multi-bucket dredger. Its design consists of buckets allowing water leakage by scooping and removing the alluvial materials and the possibility of slipping of accidentally caught fishes.
Reducing the factors /waste, noise and vibrations/ having harmful affect on the environment
The waste generated by the overall activities of the enterprise are domestic and industrial - / paper, plastic, metal, etc., formed as a result of repair work on machines and equipment /.
The household waste is collected in suitable containers and transported by a company having appropriate authorization document.
The industrial waste are formed only on the bank /on the port and as a result of the administrative activity /. Their collection is carried out separately and is in accordance with the internal company rules and relevant normative regulations.
The company monitors and controls strictly the noise and the vibration which are mostly caused by work activities of vessels -/ ships and dredgers /. The engines of the vessels available in Polaris – 8 Ltd. are of silent type. Plastic rollers of belt conveyors are used instead of metal to reduce the noise during operation of the dredger . Thus, the noise discharged in the environment during the work of the dredger is much lower than that by the use of metal rollers.
