Big Savings on CO2 Emissions Thanks to Trenchless Installation

In the jacking process, pipes are pushed through the soil after a pilot drill. Since this installation method does not require opening a trench it is ideal for densely populated areas and also provides benefits for the environment: 376,734 tons of CO2 have been saved by choosing jacking over a traditional open-trench installation of a 5.7 km-long pipe section with a diameter of 3 m in Warsaw. This number equals the yearly emissions of 104,430 medium-sized cars.

Environmental Management with ISO 14001

Based on the international standard ISO 14001 for setting up and developing an environmental management system to continuously improve environmental performance, the HOBAS Group improves its eco-balance year by year. Cost- and energy-efficient management of raw materials
and production processes is a matter of course for us, as is minimizing resource use and any impact on the environment. The ISO 14001 standard is implemented in all HOBAS Factories and compliance is monitored and proved by TÜV audits.

„XMercury“ Device in full operation 2018

The starting point for the development and finally successful implementation of the Mercury Reduction Plant “XMercury” was the Minamata Agreement launched by the UNEP in 2013, in which the cement industry was also required to make an important contribution to the reduction of global mercury emissions and inventiveness of the Wietersdorf technicians. Together with its project partners, w&p Zement GmbH saw this as an opportunity to take a pioneering role in its industry sector.
In 2013, the first preliminary tests were carried out on rotary kiln III in Wietersdorf. In 2015, the world’s first prototype plant was successfully put into operation after only six months of construction. After three years of trial operation, the “XMercury” system was put into full operation at the beginning of 2018. In the meantime, the second “XMercury” plant has already been built and put into operation in a German cement works.
With the installation of the “XMercury” plant at the Wietersdorf site, mercury emissions have been reduced by more than 80% over the past three years. Before operating the “XMercury” plant, typical monthly average levels of mercury of approximately 30-35 μg / Nm³ (ie approximately 30-40% below the currently valid limit value) were emitted. Currently, the monthly mean values are in the range of approx. 5 – 10 μg / Nm³ (ie> 90% below the currently valid limit value). The “XMercury” plant thus has a significant share in the ambitious goal of Wietersdorf cement plant of w&p Zement GmbH: to become one of the cleanest cement plants in the world.
