Der durchschnittliche Zuckerertrag in den deutschen Anbaugebieten der Nordzucker betrug in der Kampagne 2019/20 12,8 t/ha und lag damit auf dem Niveau des Vorjahresertrags von 12,7 t/ha, jedoch deutlich unter dem 5-jährigen Mittel von 13,45 t/ha.
As in the rest of Europe the dry and hot summer of 2019 was, like in 2018, affecting the sugar yield and the beet quality parameters. However, heavy rainfall by the end of September resulted also in other issues as a low pol content and high tare figures. Despite the low sugar content, beet yield was quite on normal levels, resulting in a campaign length of about 130 days at all three factories. The beet cultivation and harvest, main investments and process disturbances of the 2019/20 campaign at the three factories Anklam (D), Dinteloord (NL) and Vierverlaten (NL) are discussed.
The economic situation of the European sugar industry is currently very tense. The expected introduction of a climate-neutral mode of operation by 2050 will require considerable investment in the coming decades. This will further strengthen the cost advantages of the cane sugar industry, which, in contrast to the beet sugar industry, has for many years been obtaining most of its energy requirements from the renewable fuel bagasse. In order to remain competitive with the cane sugar industry, further reductions in production costs are necessary. As it is hardly possible to increase efficiency through technological improvements, the most promising measures to reduce production costs will be to further increase the processing capacity of the individual factories and possibly extend the campaign. Using a simplified mathematical model, the influence of transport costs, labour costs and constant costs on the optimal capacity of beet sugar factories is investigated. The lowest production costs for white sugar are used as an optimality criterion.
