Kunda Nordic Tsement – experience of sustainable solutions

The case

Kunda Tsement is a cement factory on the coast of Gulf of Finland in Estonia. During late Soviet years it was an environmental, economical and social disaster.

Today Kunda Tsement is a well working profitable industry integrated in the Estonian Society contributing to sustainability in Estonia.

Kunda Nordic Tsement Developments 1993-1998

1. New owners (twice)

2. Renovation and Environmental Policy

3. Investments in new filters and later in new kilns

4. Reducing Air Pollution

5. Reducing water use

6. Investments in new wastewater treatment

7. Reducing Emissions to Water

7

1992 Cement production - the third largest contributor to air pollution in Estonia (10% of cement – into the air – due to poor technology)

By installation of new filters dust emission from the kilns thus have decreased from almost 80,000 tonnes (!) in 1992 to 2,000 tonnes in 1997).

Large heat pump for district heating with natural refrigerant R717 (ammonia)The city of Drammen decided to use R717 (ammonia) as a refrigerant instead of R134a-prevents emission of a potent fluorinated greenhouse gas -saves electricity (about 15 %)

1620.04.23

R134a: potent greenhouse gas (GWP=1430; GWP of CO2=1). Leakage rate of the system = 2 %A 14 MW heat pump would require a charge of approximately 14,000 kg R134a (1 kg/kW). A leakage rate of 2 % emission of 280 kg x 1430= 400,040 kg CO2-equivalent annually!Equivalent to 1.4 Million miles in a car.

If electricity is provided by renewable sources, the heat pump is able to operate 100 % climate neutral. Heat source of the device is sea water (installed by Star Refrigeration (Glasgow, Scotland) & Norsk Kulde (Norway)).
