Products and Projects

What do the CD you are listening to, the mattress you sleep on, the clothes you wear, the hangover cure that sees you through the morning after the night before, the prescription drugs that the doctor gives you, the pesticides that are sprayed on fields near where you live (and are on the food you eat), the skin of that sausage you have just eaten…all have in common? There is a good chance that some if not all of these products are at least partially made by Bayer AG. Bayer are one of the most ubiquitous corporations going, you may not know it but their products are all around you (and inside you).

Bayer produce very few products that are recognised by the general public. Well known Bayer brands include Alka-Seltzer, One-A-Day vitamins and Baby-Bio. The following section is a division by division overview of Bayer's products.

Bayer Healthcare

[1] Bayer's healthcare division is divided into five further segments:

Pharmaceuticals [2] Bayer's most famous product during the last few months has been Cipro, ( a broad spectrum antibiotic which is used against anthrax. See the Corporate Crimes section for more information on how Bayer managed to overcharge the US and Canadian governments for Cipro and made a fortune out of the anthrax attacks.

Another flagship product is Avelox, ( an antibiotic.

Bayer also manufactures Aspirin Protect in Germany

Bayer's products in the UK are:

  • Adalat (nifedipine) (Cardiovascular)
  • Ciproxin (ciprofloxacin) (Anti-Infective)
  • Glucobay (acarbose) (Metabolics)
  • Nimotop (nimodipine) (Central Nervous System)
  • Trasylol (aprotinin) (Cardiovascular)
  • DTIC-DOME (dacarbazine) (Oncology)

Biological Products [3] The Biological Products division manufactures human therapeutic products, all except one of which are derived from human plasma.

Consumer Care [4] Bayer Consumer Care makes over-the-counter drugs. Its best known products are Aspirin, Alka-Seltzer, One-A-Day, Antan, Baygon and Canesten.

Such products include the fungicide Folicur®, the herbicides Goltix® and Sencor® and the insecticides Bulldock® and Baythroid®.[8]

Bayer has greatly expanded its crop protection business with the acquisition of Aventis CropScience (ACS). The purchase agreement was signed in October 2001.

Crop Science Research & Development

Bayer's Agricultural Centre at Monheim, between Düsseldorf and Cologne, is one of the biggest research centres of its kind in the world. Here, research is carried out into methods and products in the field of crop protection.

Bayer and the Aventis CropScience purchase

In early October 2001 Bayer AG finally acquired Aventis CropScience at a cost of €7.25bn (£4.5bn)[12], their largest single purchase ever. In so doing Bayer CropScience, as its new agriculture division will be known, have become the second largest agro-chemical and seed company in the world behind Syngenta. They have also become the leading company pushing forward the commercialisation of GM crops in the UK and Europe, and are just one of a few companies selling GM crops in the US, Canada and elsewhere in the world.

Aventis CropScience was formed in late 1999 by the merger of AgrEvo (itself a joint venture between the agricultural businesses of Hoechst and Schering) and the agricultural business of Rhone-Poulenc. At the time of the sale to Bayer, Aventis CropScience had a substantial portfolio of products including GM seeds (both herbicide tolerant and insect-resistant lines) and a range of agro-chemicals.[13] Its 2000 sales were worth €4,034 million and it employed about 14,400 people in more than 120 countries worldwide.

Having shed its loss-making CropScience business (it is also currently in the process of selling off its Animal Nutrition business[14]) Aventis is now concentrating on pharmaceuticals. It will, however, retain all future liability for damages claims made in relation to last year's (2000) Starlink GM contamination scandal.[15] Aventis have already launched a huge advertising campaign to try to re-brand themselves as the squeaky clean, benevolent drugs company that will save the world (see the CW subvert on the back cover of the December 2001 edition of The Ecologist).

Despite considerable existing holdings in crop protection, until now Bayer has kept its distance from GM crops, preferring a more 'traditional' reliance on agro-chemicals. Its acquisition of Aventis CropScience has vastly enhanced Bayer's agricultural sector, particularly in herbicides and conventional and GM seeds. Bayer now owns over half of the GM crop varieties currently seeking approval for commercial growing in the EU. These include 9 varieties of oilseed rape and one variety of maize, all of which are modified to be tolerant to the herbicide glufosinate ammonium, or Liberty, also now owned by Bayer.[16] Should the de facto EU moratorium on the commercial growing of GM crops be lifted, Bayer will be best placed to flood European fields with GM crops. In the UK Bayer will be responsible for the majority of GM field trials, including the controversial farm scale trials, during 2002.

The new Bayer CropScience will form one of Bayer's new independent corporate units. At the time of writing (late January 2002) it is uncertain quite how the new company will look. The European Commission has launched an enquiry into the CropScience purchase claiming that competition may be significantly reduced in the areas of insecticides, herbicides, fungicides and seed treatment products.[17] Bayer may be forced to sell off certain areas of CropScience. Prior to the acquisition, BASF had expressed an interest in buying some, or all, of Aventis' insecticide business.[18]

Although the composition of the management of the new company has recently been announced, it remains to be seen quite how Bayer's existing agricultural concerns will be merged with Aventis CropScience, and what the implications will be for shedding of infrastructure and job losses.[19] Recent articles in the financial press suggest that the merging of the two agricultural businesses may result in 3, 000 job loses. [20] Likewise its strategy for expanding sales of GM crops is still unknown.
