SCHWARTE PROCESSING – The specialist for sensitive substances

SCHWARTE PROCESSING is one of the market and technology leaders in Europe as regards tank and apparatus building for the storage and processing of liquid foods and other sensitive substances. Our product portfolio includes high-quality steel storage and process tanks of various sizes right up to large silos which we can produce entirely vertically in our silo tower. Apart from our tanks, we also produce apparatus for many different processes like e.g. fermentation or sterilisation, which we also implement in existing production structures. The construction of tank heads of different types and sizes rounds off our varied offer. On a production area of 70,000 m2, we have over 250 employees of all disciplines – from engineering to metal processing and service and maintenance - at our Polish locations in Olsztyn and Koszalin. Which also makes it possible for us to realise large projects within a short time, right down to the construction of complex special solutions, and to continue to provide a professional service to your company also after completion of the project. In short, whatever your plans are, we make sure that none of your wishes remains unfulfilled.


SCHWARTE PROCESSING is part of POSSEHL Mittelstandsbeteiligungen GmbH, PMB for short, with its headquarters based in Lübeck. PMB is a solid and reliable partner for SCHWARTE PROCESSING as a long-term investor albeit one without short-term sales strategies. As a subsidiary of L. Possehl & Co. mbH, the PMB is committed to over 170 years of Hanseatic business tradition, and, as an investment company, is convinced that a solid partnership will continue to form the backbone of a healthy economy. There are currently nine medium-sized companies with a total turnover of approx. € 210,000,000 per annum and around 1,000 people employed by the PMB. At the same time, SCHWARTE PROCESSING and the other participating interests from within the group of companies operate entirely independently, however they do benefit from the mutual exchange as well as from the years of experience and innovative strength of POSSEHL at the same time. The PMB reinforces its companies in a targeted way in order to overcome the challenges of the future and it actively encourages innovation and the development of new skill sets. The PMB is neither listed nor funded by private investors, rather it remains financially independent as an exclusive subsidiary of the POSSEHL group. As a result, PMB is in a position to finance equity investments solely from equity capital, such as those made by SCHWARTE PROCESSING. This provides PMB companies with a high degree of flexibility without worrying about their own debts owed to banks. That ultimately benefits our clients too. You do not have to worry about funding shortfalls or the like if you are a client of SCHWARTE PROCESSING.
