Environmental engineering: Recycling, waste disposal and pyrolysis

Niersberger Environmental Engineering is primarily focused on the topics of waste disposal and recycling. This is, for example, implemented through bio-gas or pyrolysis plants.


Pyrolysis: Final product carbon black (soot)

Hereby, a business sector of Niersberger is the pyrolysis on the basis of old tires. This is a technique whose process is aimed at the thermal recycling of used tires. It is the first processing step of the pyrolysis plant. Their goal: To produce end products such as carbon black, pyrolysis oil and pyrolysis gas. Carbon black is industrial soot, a substance which is used increasingly in the plastics industry, and is already included in many products which are used on daily basis.


Pyrolysis oil is produced from pyrolysis

Pyrolysis oil is the second significant end product. It is also attained through the thermal recycling of used tires using the pyrolysis process. The high quality of the oil derived from tires allows for a wider use in the petrochemical industry.


Pyrolysis: Recovery of resources

Especially today, this recovery of resources from the pyrolysis process plays a role that should not be underestimated. While in North America, for example, the production of crude oil from sand inflicts severe damages to the cultural landscapes and nature through the open pit mining and destroys it in the long run, the pyrolysis solution is a much more gentle procedure. Because it is based on the recovery of crude oil, pyrolysis gas and soot, without having to rely on fossil resources which are ultimately only obtained through mining or offshore drilling.


Pyrolysis gas

Pyrolysis gas is produced as a third usable end product. Before the pyrolysis gas becomes a marketable product, it must be processed or refined. The gas is thereby cleaned or "washed" to remove individual components, foreign objects or dust. Only when the pyrolysis gas has been completely processed, can be used as a source of raw materials for chemical applications in addition to the use for electricity or heat generation.


Pyrolysis as a project

The commitment of the Niersberger Group towards the topic of pyrolysis commenced in 2011 with the creation of the first project team. In 2012, the first order for the construction of a pyrolysis plant for old tires in Poland was received.

By now, even investors have discovered environmental engineering as a field of activity for themselves, and are looking for attractive locations and sustainable pyrolysis projects.
