From teacher to CEO - Maria Vogelsang-Verhülsdonk

When Maria Vogelsang-Verhülsdonk walks through the corridors at Vogelsang, she is proud of what she
has achieved in this company. With good reason, Maria Vogelsang-Verhülsdonk was awarded a prize
for her lifetime achievements in business in 2015 by the regional development association “Verbund Oldenburger Münsterland”. “The company is a role model for how a family-run business can be successfully developed.”

Episode 1: How wet wipes turn into sewer monsters

Operators of sewage systems like waste water associations or municipalities have been facing a new challenge in recent times: More and more hygiene products and disposable cosmetic products are not thrown in the trash, they end up in the toilet and then in the sewage system.

Germany is currently suffering from circumstances that are difficult to predict as far as future gas supplies are concerned. Private households fear power outages and industry is also suffering from the unpredictable situation. Consequently, gas prices are rising sharply, which is why mineral fertilizer production is becoming increasingly expensive. Due to the current situation, some fertilizer producers are even closing their factories. How can farmers and companies deal with the current mineral fertilizer crisis and why does liquid manure play a key role? We look at the sustainable solution of near-ground spreading technology and your opportunities for the future.

Partnership for plant optimization: In Nohra, Vogelsang and Biocraft Nohra are working with partners from industry and research on the “FlexPump” project – a mixing concept for the flexible, efficiency-optimized and multifeedstock- capable operation of biogas plants.

Successfully marketing worthless items. Colloquially in German, one also likes to say: “Making money from sh**.” In Grammetal, they take this literally – and quite successfully, actually. There, animal excrement is
economically converted into energy in the biogas plant of Biocraft Nohra. The trigger for the change in the operating concept was rather unpleasant: the neighboring industrial company, which used the entire heat of the plant, closed its doors. They had to come up with something new. Now, their efforts have been impressively successful and, in addition, added value has been created for the environment and for regional farms.

A biogas plant provides an efficient, economical and sustainable method of generating energy. A particularly important aspect of the biogas plant is the digester feeding; this is decisive for the gas yield. But how does solid matter feeding suitable for bacteria work? The potential of “liquid feeding” is a widely discussed method in this context.

Using a state-of-the-art Vogelsang solid matter feeder, it is possible to prepare and mix solids with a liquid component in a particularly advantageous way. This treatment enables you to increase your gas yield and reduce your energy costs. How does this work and what technology can help you? Let’s take a closer look!

Who would have thought that dentures, identity cards or beer bottles could be found in wastewater treatment plants? It is patently obvious that wastewater treatment plants are not designed for these materials. Another product that are a major challenge for wastewater treatment plants is wet wipes. In many cases, they have become an indispensable part of the household. Wet wipes are used for various purposes, such as cleaning a baby's bottom or special cleaning wipes for toilet or smooth surfaces. However, not every wipe is the same.

There is waste in almost every production area. This is also the case with the production of bread. In large bakeries and supermarkets there are tons of bread every day that have to be sorted out for various reasons. However, this waste contains many valuable raw materials and is far too good “for the bin.”

Heavy rain is overloading sewage systems and treatment plants more and more frequently. Storm tanks keep the drainage flowing smoothly.
