For a steel works in Ostrava (CZ), STAG was awarded the contract to engineer, produce and supply a conveying and injection system for hearth furnace coke (HOK) and limestone (CaCO3) for the purpose of separating dioxides from the flue gases.

In connection with the modernisation of the sewage sludge treatment system, STAG has been charged with the provision of all conveying technology and bulk material storage facilities on behalf of ARA Bendern (association of Liechtenstein communes for was

Modernisation of the refinery Petrobras based in Northern Brazil and installation of a new flue gas cleaning facility were carried out at the beginning of 2010.

In the area of water treatment and sewage sludge recycling, STAG implemented over the past years some pneumatic bulk material conveying and storing projects on behalf of the plant operator “SIAAP” in the Paris region.

In order to avoid overheating of dry sewage sludge, the material must be regularly shifted. For this purpose, a pressure conveying vessel provided with two outlet flaps has been installed underneath each storage silo.

At its location in Duisburg-Huckingen, Germany, the Hüttenwerke Krupp Mannesmann GmbH (HKM) runs an integrated iron and steelworks.

In 2013, a modern coal block has been put into operation in Karlsruhe. For this project, STAG was entrusted with the engineering and delivery of the mechanical and pneumatic ash removal of the electric filter.

In 2014, a new waste-to-energy power plant equipped with two lines was built in Vantaa, Finland. The two general contractors for boilers and flue gas cleaning opted for conveying technology made by STAG.

In 2006, STAG received the contract of Fisia Babcock Environment GmbH to equip the lignite-fired power plant (BOA ll - RWE) in Neurath, Germany, with pneumatic conveying facilities designed for the ash removal of electric filters.

Due to its wide experience in the area of ash removal from lignite-fired power plants and to notable reference plants, STAG managed to successfully implement a project in Kosovo on behalf of  Hamon Environmental GmbH.

In Gelsenkirchen, BP is running refinery and petrochemical plants in the city districts Horst and Scholven.

Based on their long cooperation in the area of conveying systems for thermal waste treatment plants, Hitachi Zosen Inova and STAG have already realised several projects together.

In Istanbul, Turkey, the biggest waste-to-energy plant in Europe is being constructed.
