Styria is the second largest state of Austria, in the south eastern part of the country. It is famous for its beautiful mountains, its wines and some decent yodelling 🙂

It is also home to green tech industries, in fact “Styria is home to more than 150 clean technology companies … [whose] revenue totals €2.7 billion. This equals to 8 percent of the Gross Regional Product (GRP), and is one of the highest concentrations of leading clean technology companies in Europe.” (Wikipedia)

The ‘Styrian Promise’ is a project aiming at the implementation of energetically and economically meaningful energy efficiency concepts in Styian production companies. Case studies from food, textiles, metals and other industries are presented on the project wiki.

Above is a Sankey diagram depicting the energy balance at Obersteirische Molkerei Knittelfeld (Upper-Styrian dairy in Knittelfeld). Flows are in MWh per year. The main energy requirement is steam from natural gas: Whey drying and steam for milk pre-heating are the largest consumers of process heat. Read more detail on the dairy production here.
