Pipelines for the disposal of waste water have existed since Roman times. The rapid development of cities in terms of inhabitants and traffic has led to a demand not only for the construction of new sewer lines but also for the reconditioning of existing sewers, some of which are often more than a hundred years old.
New technologies have been developed for the reconditioning of waste water sewers, especially in inner-city areas, so that work can be carried out without having to dig ditches.
SWIETELSKY and its specialists have many years of experience in the relining method. The advantages of these systems are:

Renewable raw materials, such as maize and grass silage but also biogenic waste, are the substrates from which electrical and thermal energy are generated in the SWIETELSKY biogas facilities. The electrical energy is supplied as green electricity into the public power grid. Thermal energy is primarily used in district heating systems. The end substrate from the biogas process is ideal as a biogenic fertilizer as it demonstrates enhanced plant tolerance, nutrient supply and emission values.
As an experienced general contractor, SWIETELSKY constructs biogas facilities professionally and ready for use, tailored to regional requirements and operator stipulations. The high quality and safety standard is guaranteed by the monitored process control in these facilities.

SWIETELSKY operates 30 asphalt mixing plants in Austria, Bavaria, the Czech Republic, Hungary and Croatia, 6 concrete mixing plants in Austria and Hungary as well as numerous gravel reprocessing plants. The asphalt mixing plants are operated either individually or collaboratively. Three asphalt mixing plants have been modified in order to be able to produce melted asphalt. A number of plants are equipped with recycling facilities in order to process old asphalt as well. Plants of high production capacity are equipped with heat mineralisation, thereby increasing the flexibility of ready-mix production.
