On the production territory in Kohtla-Järve, the semi-coke pipe conveyor was launched, and in the future, the entire amount of waste from the oil shale plants of Viru Keemia Grupp, both semi-coke and ash, will be forwarded to the storage area via the environmentally-friendly pipe conveyors. It is an innovative solution that has been used in the latter decade in many branches of industry, but VKG was the first one in this region that has implemented this technology. The use of this system means a considerable decrease in the effect exerted on the environment, cleaner production territory, and higher economic efficiency. The investment in the amount of 1.5 million of euros was made into the development of the semi-coke pipe conveyor at Kiviter, and it allows to stop using trucks for loading semi-coke at the plant and taking it to the dumpsite in the hills. The trucks had to climb the hill 50 metres high on the path of 900 metres, which was accompanied by significant fuel consumption and a high level of CO2 emissions. The pipe conveyor has helped to decrease the path driven by trucks by 2.5 kilometres, which means that the total reduction of the number of kilometres driven per day is 625 km, and 563 litres of fuel is saved. The ash generated at Petroter plants has been taken to the dumpsite since 2015. The ash conveyor was launched together with the third Petroter oil shale plant, and this logistic solution cost 10 mln euros.
