Cheminova

Cheminova was founded in Copenhagen in 1938 by the civil engineer Gunnar Andreasen. At first, it produced anti-rust treatments at a factory located north of Copenhagen at Sydmarken 10–12, Mørkhøj. Production of the treatments was halted during the German occupation of Denmark under the Second World War because the required raw materials were unavailable. Instead, the company began to produce alternatives for various goods that were difficult to obtain in Denmark as a result of the war. These included replacements for raw rubber and sugar, as well as thinners for paints and varnishes. The factory was twice sabotaged by Danish resistance groups: by Holger Danske on 2 January 1945, and by BOPA on 14 February 1945.

From 1944–46 a new factory, again close to Copenhagen, was built at Måløv Byvej 229–233, Måløv. Production there was concentrated on insecticides, since the Allied victory had led to the release of several German patents for these chemicals. However, the factory had ongoing disputes with residents and the local authority regarding the effect of waste water from the plant on aquatic environments. Partly as a result of this, in 1953 the company moved its operations to Harboøre Tange (a large sand spit) and Rønland (a peninsula), near Lemvig in West Jutland, where its main operation remains today.

A further reason for the relocation was the presence of a large salt dome under Rønland: chlorine was an important constituent of the company's products, and it was thought that the new plant could extract this from the local salt, with any excess sold on for profit. One of the company's first purchases after the relocation was a salt extraction plant, which was quickly decommissioned after the local authority's decision to refuse permission for the sale of the excess salt made it unprofitable.

In 1943, Gunnar Andreasen transferred all Cheminova shares to Aarhus Universitets Forskningsfond (Aarhus University Research Fund).

Cheminova's current products include insecticides, weedkillers and fungicides, as well as some fertilisers. These agrochemicals are mostly sold as ready-to-use mixes under own-brand labels and registrations. In addition, a number of non-agricultural chemicals are sold, including froth flotation aids for the mining industry and preservatives for the food industry.

For a number of years, organophosphate pesticides (such as Parathion) were Cheminova's main product. This later diversified significantly into the wider portfolio mentioned above, partly through internal development, but also through purchasing from competing companies.

This development has focused on improving the chemical processes used for production, and also on reducing the environmental impact of the products. Alongside this, a number of very toxic pesticides (so-called WHO class products) have been phased out.
