About RUDLOFF
RUDLOFF GmbH is a medium-sized, owner-managed family business in its second generation, headquartered in Sereetz near Lübeck. The company has been active since 1960 and combines two business areas: the propagation and marketing of field and lawn seeds as well as the production and trade of small animal feed. At the headquarters in Sereetz, imported raw materials are dried, cleaned, processed in a fully automatic mixing and packing line and stored in the 6,300 m² high-bay warehouse. Schönberg serves as the processing centre for fine seeds, legume and cereal seed; in Westerrade, feed components are received, cleaned and, among other things, treated by electron treatment. Around 130 employees generate an annual turnover of approximately €60 million with about 30,000 tonnes of goods handled per year. The product range includes grasses, maize, rapeseed, legumes, flowering and wildfield mixtures as well as pigeon, bird and rodent feed; customers come from agriculture, organic farming, landscaping (GaLa-Bau), agricultural trade and specialist retail.
