Renewable energy technology

That Niersberger has become active as a classic installation company in the market segment of renewable energy technology, is obvious. The basic expertise is available. Only a transformation of this basic knowledge had to be conducted in order to ultimately be successful in this innovative segment.


Finite nature of fossil fuels

In this business area, Niersberger focuses on photovoltaics and the waste fermentation as well as the production of biogas. The reason: The finite nature of fossil fuels. Even nuclear fuels such as uranium are not available in endless amounts. On the contrary: in 60 years, the global uranium deposits should be used up. The situation with fossil fuels is even more volatile. In approximately 40 years the supplies of fossil fuels, such as petroleum, will start to deplete. That's what the International Energy Agency IEA is saying. In about 8 years, according to the IEA experts, the global peak of oil production will already have been reached. Afterwards, alternative energy sources will need to cover more and more of the emerged gaps. In the Federal Republic of Germany alone, approximately 20% of the total energy requirement is provided by renewable energy sources. By 2020 it is predicted to even be 30%, and by 2030 up to 40%.


Approaches for regenerative energy technology

This is the basis for a logical starting point for the use of renewable energy technology. Here, Niersberger designs custom solutions, based on concrete and realistic requirements. This conceptual spirit pervades the entire development phase, continues into the implementation and finally has its finale in the installation and commissioning. Thereby, each facility is different. Because each installation meets the customer's specific requirements and is based on an individual approach.


Waste fermentation

Since 2004 biogas plants from Niersberger have been producing biogas from organic waste (liquid manure, manure, sewage sludge), organic waste and plant material (corn, grass, sugar beets etc.), and converting it into electrical energy and heat.

In the particular case of organic waste, biogas is attained in a so-called waste fermentation plant. A technical step, which reduces odor emissions and allows for the proper recycling of bio-waste. The digestate is processed further as fertilizer. A closed and above all sustainable cycle that leaves no traces.

Thus, the Niersberger Group received a major order for the construction of a complete biogas plant from E.ON in 2008. This was the largest biogas project to date, with a total volume of EUR 10 million.
