Therefore it is of the highest priority to pursue economic, social and ecological goals - equally and simultaneously. The company strives to create long-term value, offer good working conditions and treat the environment and natural resources responsibly.
From incoming customer orders through product development, supplier selection and production to delivery of the final product. In addition to the primary objectives of the Rosenberger Group including the preservation and protection of natural resources, great importance is attached to the proper disposal of polluting emissions and waste.
Further corporate goals include replacing energy from conventional sources with renewables and the elimination of environmentally harmful materials and substances. Rosenberger is certified to ISO 50001 and since 1998 to ISO 14001 including subsequent recertification.
Since 2020 Rosenberger has been making its entire energy and heating requirements CO2-neutral at the company headquarters in Fridolfing.
Rosenberger thus compensates for CO2 emissions through emission savings from the climate protection project "Kinnaur Hydropower Plant" in India. In addition, Rosenberger uses a certificate of origin for the greening of its electricity requirements by means of the energy production of green electricity in Poland.
In 2017 a new production building for surface coating - the single most expensive investment in the company's history - was put into operation. With the construction of this new electroplating shop a number of new facilities as well as safety precautions have been installed, all of which of course meet the European standards of the best available technology.
Because environmentally harmful chemicals are used during the electroplating process, along with plant requiring approval, the new building falls under the Federal Immission Control Act (BImSchG). The approval procedure is particularly demanding as all potential environmental effects must be evaluated.
The safety precautions include a fire alarm system with smoke detectors in the ventilation systems. In addition, the surface technology is protected against accidents on several levels with the derivation and interception of liquids escaping from electroplating baths being a top priority.
The production process means a large proportion of the metals used end up as oil-contaminated chips. However, two chip and oil processing systems co-developed by Rosenberger enable cleaned oil to be pumped back into the cooling system and the metal chips - now containing less than three percent oil - to be returned to the materials supplier almost sorted by type.
This ensures optimal recycling of materials and only small quantities of new raw materials needing to be purchased.
A special feature is the highly efficient biomass heating plant. About one fifth of the total energy required is generated by the heating plant using renewable energy sources - in this case local wood chips.
Rosenberger can cover a large part of its heating needs through the biomass heating plant. To meet the same energy demand with oil fuel about 420,000 liters would be necessary. Rosenberger’s initiative therefore translates into an emission saving of approx. 1,121 tons of CO2.
Various systems are used to recover heat from exhaust air, compressors and oil used for cooling purposes. The heat obtained is used to heat buildings and therefore contributes to savings on oil fuel.
The new Energy Center has two new air compressors including a heat recovery system and since 2008 about 4,200 MWh of heat energy has been recovered. Accordingly, more than 1,000 tons of CO2 have been saved.
In 2020 Rosenberger installed a photovoltaic system with 3,000 modules and 935 kWp for its own supply. The system supplies the company with approx. 800,000 kWh of solar electricity per year, thus saving almost 470 tons of CO2 per year. At the same time emissions such as lead, nitrogen oxide or mercury are reduced.
A special feature of the photovoltaic system is the zero feed-in whereby Rosenberger uses 100% of the electricity produced by the solar plant. This does not feed into the public grid and therefore dispenses with the state buyback price.
The sustainability report of Rosenberger Hochfrequenztechnik GmbH & Co. KG provides an insight into the company's data, figures, strategies and goals as well as its sustainability-related activities. The report refers to the corporate headquarters in Fridolfing and has been prepared in accordance with the "Core" option of the GRI standards of the Global Reporting Initiative.
The dedication that we show to our sense of social and ethical responsibility and to treating our environment with respect, are vital elements of our corporate philosophy. This is why we are continually working to implement practices such as obtaining energy from renewable sources and achieving an overall reduction in CO2 emissions.
In order for the partnership that Rosenberger has established with its suppliers to achieve success over the long term, both parties require a common understanding of the sustainability policy outlined in the remainder of this document.
