Lonza Group

Lonza Group is a Swiss multinational manufacturing company for the pharmaceutical, biotechnology and nutrition sectors, headquartered in Basel, with major facilities in Europe, North America and South Asia. Lonza was established under that name in the late 19th-century in Switzerland. The company provides product development services to the pharmaceutical and biologic industries, including custom manufacturing of biopharmaceuticals and detection systems and services for the bioscience sector. History Lonza was founded in 1897 in the small Swiss town of Gampel, situated in the canton of Valais, taking its name from the nearby river. In the course of the 20th century Lonza evolved from hydroelectricity and C2 chemistry, through nitrogen chemistry to petrochemistry before moving into fine chemistry and biochemistry. Initially, the company produced electricity. The following year, calcium carbide manufacture began using the electricity to heat a furnace to the 2000 °C required for quicklime to react with coal. Lonza moved to neighbouring Visp (where it retains a production site today) in 1909. Competition from electric lighting reduced demand for calcium carbide and in 1915 Lonza started industrial production of calcium cyanamide which became popular as a cheap nitrogenous fertilisers, only to be supplanted by urea. Several new processes were launched in the 1920s. In addition to an electrolysis plant capable of making 5800 m3 hydrogen per hour, came metaldehyde, ammonia and ketene. In 1923, Lonza started to convert calcium carbide to metaldehyde (sold as a solid fuel under the brand 'Meta' and then slug repellant) via acetylene and acetaldehyde. In 1925, ammonia production was started, with a process licensed from Casale. Ammonia was also converted to nitric acid. With calcium cyanamide and calcium nitrate (made from nitric acid), Lonza commercialised formulated fertilisers starting in the 1930s. At the start of World War II, Lonza was contracted by the Swiss government to produce synthetic fuel, which it did by converting acetaldehyde to paraldehyde, used as an additive in transport fuel. In 1928, ketene production started using acetic acid made by oxidation of acetaldehyde. Ketene was initially used to make cellulose acetate for rayon manufacture, but after 1947 Lonza converted most of its ketene to diketene, which was then converted to a range of chemical precursors. Diketene capacity rose to 18'000t per year in 1993.
