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.

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 %)
14
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)).
