history
The company was founded in 1750 and traded as Wilhelm Connemann . In the following decades the company worked as a mill for shell limestone , bone mill , soda factory, factory for compressed yeast and grain distillery. In the middle of the 19th century, a new soap factory was built on Henry's property on Osterstraße (today Mühlenstraße) and in 1887 the oil mill in Leer was the first oilseed extraction plant in Germany to go into operation. In 1936, the company was also given an area of around four hectares on the opposite port site on the Nesse with heritable building rights for flax utilization and flax roasting. Since the 1950s the wood import and wood processing company Wilhelm Connemann and Theodor Schiewe worked on the Nesse. After Connemann had developed a chipboard from flax shives in 1949/50, a chipboard plant was also built on the Nesse for Wilhelm Connemann flax recycling, which produced so-called "Lino" chipboard according to its own system. In the 1970s, the factory in the city center was demolished and converted into Ernst-Reuter-Platz, a multi-purpose area with parking spaces and a children's playground.
In 1987 Wilhelm Connemann went bankrupt . At the time, the company was the second largest in the city. The plants were then taken over by the Hamburg oil mill . Joosten Connemann, who continued to work for the company as managing director, developed a process, patented in 1993, with which biodiesel can be obtained in a continuous process from rapeseed oil and other vegetable oils, according to which the twelve largest plants worldwide were operating in 2007. In 1993, a pilot plant with an annual capacity of 7,000 tons of biodiesel was built on Sägemühlenstraße in Leer, which was followed in 1995 by Europe's first industrial biodiesel plant with a capacity of 80,000 tons. After the chipboard factory was closed, the heritable building site was transferred back to the city in September 1998. After the demolition of the industrial development, a new district with residential and commercial buildings was created on the site, the "New Exhibition District".
The operation of the rapeseed oil extraction plant was terminated in 2004 due to difficult framework conditions, but biodiesel production continued with the rapeseed oil supplied. In December 2007 the Connemann oil mill changed its name to Leeno medical , which manufactures transport equipment for hospitals, old people's homes and industry. In 2008, the parent company Ölmühle Hamburg was taken over by Archer Daniels Midland . In December 2015, the biodiesel plant in Leer ceased operations completely.
