Green product from Addcon keeping runways free of ice
The 52 employees of Addcon at Herøya keep track of weather forecasts in a different way to most other people. Slush, sleet, rain and around 0 C – perfect weather. This is when runways at Gardermoen airport and all other runways in Norway, including those at military bases, are sprayed with de-icing agent from Herøya.
AIR FORCE 1: The runway at Gardermoen was sprayed with de-icing agent during a presidential visit a few years ago.
"We also export the de-icing agents Aviform and Viaform to recipients outside Norway," says HSE and Quality Manager Øyvind Oskarsen Due. "Aviform is used to de-ice runways at most airports in Norway and at 60-70 per cent of airports in Denmark, and also in several other European countries, especially Germany," he says.
Addcon's Viaform de-icing product is also used on artificial turf, so that matches can be played throughout the winter season, with no need for under-heating. "We also supply de-icing agents for use in parks and avenues. They are used in Copenhagen, for example, where chloride-free products are needed for de-icing of streets and avenues with especially vulnerable vegetation."
"We make a number of green products that are based on potassium formiate and sodium formiate, with and without combinations with formic acid," Øyvind Oskarsen Due explains.
DE-ICING: "Aviform is used to de-ice runways at most airports in Norway and at 60-70 per cent of airports in Denmark, and also in several other European countries, especially Germany," says HSE and Quality Manager Øyvind Oskarsen Due.
Our formiate products are used in existing market niches, such as the oil industry, agriculture and airports, and the feed, fisheries and refrigeration industries.
Øyvind Oscarsen Due emphasises that the products are green because they have very low toxicity on use, and degrade very quickly in nature. This is particularly important in view of their use in oil activities, in agriculture and at airports. The fact that the products are virtually toxin-free makes their use in the feed industry, as a replacement for antibiotics, a growing market.
From Hydro to German owners
Addcon Nordic AS, with 52 employees in Porsgrunn, achieved revenue of NOK 320 million in 2015. The company was acquired by the German family-owned company Addcon GmbH in 2006, but its roots are in Hydro Agri's business development in the 1990s, which resulted in the establishment of Hydro Formates in 2001.
"This development began in1993," says Øyvind Oscarsen Due. "Formic acid was a product in the Hydro system, and a business development project was launched to find out what formic acid could be used for. Since then, we've been part of various Hydro companies, and e.g. worked with various products based on formic acid.
After Hydro discontinued formic acid production in 1996, formic acid is now imported to Herøya by sea.
When Hydro sold the fertilizer division to Yara in 2004, Hydro Formates was part of the deal, changing its name to Yara Formates, but two years later Yara sold the company to German owners. Addcon Nordic is now part of Addcon GmbH, which is one of the world's largest producers of potassium formate – the potassium salt of formic acid. The company in Porsgrunn accounts for around two thirds of the global activities.
For bakeries, the oil industry and other activities
• Every day of the year, Addcon produces 23 tonnes of ammonium bicarbonate. This is enough to fill more than 350,000 boxes of raising agent.
• The Porsgrunn company also delivers products to the oil industry under the Ecoform and Petroform brand names.
• Addcon also supplies a number of grass silage additives to the agricultural industry (for silo conservation and round bales) under the GrasAAT brand.
• Addcon supplies the Ensilox and Fishform products to the fish industry.
• Besides developing de-icing agents, Addcon also supplies HyCOOL coolants for refrigerated stores and freezing plants. • Most of Addcon's products are based on formic acid. This is where the company's expertise lies, and the focus of its product development and production.
