in a responsible manner
Since December 2013, Nordkalk in Köping has been supplying recovered residual heat to the town’s district heating network . This heat allows the town to reduce its consumption of fuels for heating, which also reduces emissions.
During winter 2014/2015, as much as 65 per cent of district heat consumed within the town of Köping consisted of residual heat delivered by Nordkalk and Yara. This is a record in Köping, and shows how local industry can contribute to the circular economy.
A heat recovery unit installed in the flue gas channel of the rotary kiln makes it possible to utilise the residual heat from the kiln. Depending on operation conditions, up to 14 MW can be delivered to the district heating network. In 2015, Nordkalk delivered 41,000 MWh, which equals the amount of energy in about million litres of heating oil.
Nordkalk is the leading limestone company on its home markets. We deliver essential raw materials to numerous industries, and our solutions contribute to clean air and water as well as productivity of agricultural land.
