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
At POLOPLAST we always aim to use packaging materials as economically as possible and choose reusable containers where viable (see photo). When buying new machines, we compare the energy efficiency and emissions of the models in question and evaluate them. Before using any raw materials, we always check that they are safe in terms of impact on our people and the environment. These consistent efforts led to all the procedures in place and to be followed being gathered together in corporate guidelines for environmentally friendly purchasing at Poloplast.

Reducing noise emissions from the plant
w&p Zement attaches great importance to achieving long-term environmental goals. The Wietersdorf facility has thus been working continuously since 1999 on reducing its noise emissions, retrofitting for example 11 silencers in the ready-mixed mortar plant and installing a new jacket cooling system with silencer on the rotary furnace. A noise barrier erected at the plant entrance is aimed at keeping the disturbance down to a minimum for local residents. All these measures have led to a sustainable improvement in quality of life around the Wietersdorf industrial site.w&p Zement > Sustainability
Water management at the south quarry, reduction in sludge
The Peggau plant constantly strives to improve its eco-balance. In the production process for high-quality building materials, it is essential to use stone fractions without any contaminants. We therefore have a stone washing plant where fine fractions (sludge) are left as a waste product. To make use of the residue, we developed a concept for removing the water from the sludge, which we implemented in 2010-2012. The main components of the wastewater treatment plant are the lamella clarifier, which separates the solids (clay and limestone grit) from the stream on plate settlers covering an area of 300 sq m, and the filter press, which further dewaters the concentrated sludge from the lamella clarifier (approx. 75% residual moisture) down to about 20% residual moisture content. With this system up to 7,000 cu m water can be treated daily and up to 250 t sludge dewatered. After the process, all the 0/4 mm sand fraction can be used as aggregate in producing construction materials or filler in concrete.
