  3. Kunda Nordic Tsement – experience of sustainable solutions The case KundaTsement 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 KundaTsement is a well working profitable industry integrated in the Estonian Society contributing to sustainability in Estonia.

  4. Kunda Nordic Tsement Developments 1993-1998 • New owners (twice) • Renovation and Environmental Policy • Investments in new filters and later in new kilns • Reducing Air Pollution • Reducing water use • Investments in new wastewater treatment • Reducing Emissions to Water

  5. 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).

  6. Reduction in dust emissions Year Dust emissions per unit of production 1992 146 kg/tonne 1996 22 kg/tonne 1997 3 kg/tonne 2004 0.4 kg/tonne 2007 0.1 kg/tonne

  7. Air quality improvement in Kunda town Year Number of times Maximum Permitted Level was exceeded per year 1994 120 1995 127 1996 50 1997 4 2005 3 2007 7

  8. Kunda Nordic Tsement Developments 1998-2005 1. Introducing an EMS and ISO 14001 Certification 2. Using Clinker Dust in Agriculture 3. Energy Management 4. Waste Management 5. Introducing an Integrated Management System 6. Economy and Public Image

  9. Innovations of Kunda tsements: • a programme to promote the use of fly ash as fertilizer • utilizing hazardous waste

  10. Clinker dust used for liming of agricultural fields Year Clinker dust (tonnes) 1996 500 1997 10,500 1998 300 1999 60,000 2000 63,000 2003 55,000

  11. Waste used as fuel in the clinker production Year Waste (tonnes) 2001 15,000 2003 47,000

  12. 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 %)

  13. 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)).
