Description

Nordkalk group is the leading producer of limestone-based products in northern Europe. Limestone-based products are used in many industrial sectors, agriculture and environmental care, such as water treatment. The company has operations in nine countries and at more than 30 locations. Nordkalk Corporation (Oy Ab), the parent company, operates in Finland, excavating limestone (calcite) at nine locations. The largest of the mines are the quarries in Pargas and Lappeenranta, as well as the underground mine in Tytyri, Lohja. Lappeenranta, Pargas and Tytyri represent a total of 90 per cent of Nordkalk’s limestone production in Finland. In addition to limestone, Nordkalk also excavates wall rock and, in Lappeenranta, wollastonite. All three mines have been in operation for longer than one hundred years. In addition to mining, Nordkalk also produces burnt and slaked lime, which is not addressed by this report. Nordkalk is part of the Finnish Rettig Group.

Impact on the use of the neighbouring areas and the sources of livelihood

Vaikutukset paikallisiin elinkeinoihin: No mining and exploration are carried out in the reindeer management area. The mine provides direct and indirect employment to local people, either as contractors or service providers. In connection with the mines, business activities are conducted in the old mining premises. There are, for example, museums and restaurants, and elevator technology is developed. Mining operations have been carried out for more than one hundred years, so the mining areas have become part of the local community.

Vaikutukset lähialueen virkistyskäyttöön:

According to the assessment of the company itself, its mining activities have not impacted negatively on the recreational use of the neighbouring areas. The company has repaired a vantage point, enabled the operation of a mining museum, and organising of concerts in the mining area.

Vaikutukset maisema-arvoon:

Landscape values have been taken into account in the operations of the company. The company seeks to sell all wall rock in order to avoid its being dumped The dumped wall rock is landscaped in accordance with the environmental permit during mining. As requested by authorities, certain areas have been left unlandscaped to enable calciphilous flora and fauna to populate the new habitats that have emerged in the area.

Underground mines where excavation is terminated are put to good use by filling them with boiler ash supplied by customers, thereby decreasing the need for dumping ash on the surface. The company has carried out one replanting (Vimpeli in 2012, field gentian). In Lappeenranta, an environmental impact assessment was carried out in 2012 and 2013 on the possible expansion of dumping areas. If carried out, the project would impact the landscape.
