ScienceDaily (Oct. 6, 2008) — As a result of the Haber-Bosch process for the synthesis of ammonia from atmospheric nitrogen, billions of people have been fed, millions have died in armed conflict and a cascade of environmental changes has been set in motion, suggests a feature article by scientists from four of the world’s leading environmental research centres that will be published online on 28 September in Nature Geoscience.
The feature appears 100 years after Fritz Haber filed his patent on the ‘synthesis of ammonia from its elements’ for which he was later awarded the 1918 Nobel Prize in Chemistry.
Lead author, Jan Willem Erisman from the Energy research Centre of the Netherlands (ECN), explains: “The increasing demand for food and biofuels makes efficient use of nitrogen fertilizer and more sustainable energy a challenge for many. Haber-Bosch is perhaps the most significant invention of the 20th Century, yet it has many side effects. Now we need a new invention that changes the world just as much, but without the environmental impact.”
According to the article, we now live in a world transformed by, and highly dependent upon, Haber-Bosch nitrogen. This extra nitrogen has allowed large scale production of explosives with the result of millions of casualties. On the other hand, it has created an enormous chemical industry producing materials and goods for society. The major impact, however, has been the large scale production of fertilizers supporting almost half of the world’s population through increased food production. Keep Reading
