- The company Pöyry operates in all fields of mining waste management, informs the latest newsletter from the Finnish Geological Survey, GTK.
Pöyry specialises, for example, in defining the properties of seepage water, identifying storage requirements, designing waste area structures, surveying the building capacity of the ground and planning the closure of mining waste areas. The results of all work stages and reasons for each solution used are always entered in a mining waste management plan.
– The storage of mining waste has a significant impact on land use, which is why social and financial impacts on local communities need to be identified. The management of mining waste is part of the financial optimisation of projects. The disposal of financially valuable elements and usable materials that can be separated should be prevented. The circular economy has for long been part of mining waste management, and mining waste will be used in more diverse ways in the near future, says Päivi Picken, a senior environmental consultant at Pöyry.
Picken points out that Finland has significant expertise in mining waste management, even though the field can be fragmented at times. The interaction between technical design, financial estimates and environmental surveys should be developed. Pöyry also aims to spread globally recognised and accepted operating methods, as they communicate sustainable operations and help to obtain financial support.
