:: VTT Views Mineral Scarcity and Environmental Technologies as Opportunities


As mineral resources are dwindling, it is becoming increasingly important to know how even the tiniest amounts of minerals can be recovered from waste - or how minerals can be substituted for other materials in industrial use. The VTT Mineral Economy innovation programme develops new technologies for, for instance, the mining industry.

VTT Technical Research Centre of Finland Ltd has launched an innovation programme for developing new technologies for the recovery of metals and other minerals, and improving the recycling of raw materials by means of ecological product design. The objective is to turn threats, in other words raw material scarcity and environmental challenges, into new business activity and jobs in Finland and in Europe.

It has been estimated that the amount of important minerals for industrial production will dwindle in about twenty years unless we find new sources of minerals and develop alternative sources of energy very soon. Such sources could include tailings from mining operations and consumer waste. Various methods could be employed to extract the valuable substances contained in these more effectively than can be done today.

Substitution of critical raw materials in, for example, electronics and power tools also offers excellent opportunities for finding solutions for raw material problems. At the same time, attention must also be paid to product design, to ensure that valuable raw materials are easier to recover in the recycling phase.

Olli Salmi, Research Professor at VTT: "The current recovery methods are too crude, and in the future, they have to be replaced with more refined methods that save the environment." As an example, he mentions the recovery of gold using mushroom mycelium mat filters, a method developed by VTT. One of the ongoing projects includes developing hydrobiometallurgical recovery equipment for minerals to the pilot phase.

In the best possible case, recycled raw materials can be substituted for harmful or critical raw materials used in production.

In 2014, the volume of mineral sector R&D at VTT was approximately EUR 6 million. The project portfolio mainly consists of projects financed by the EU and Tekes, as well as customer projects.

EIT Raw Materials Co-location Centre to Otaniemi

VTT Mineral Economy innovation programme will collaborate closely with the innovation consortium financed by the European Institute of Innovation & Technology (EIT), to be launched this year. The EIT Raw Materials community is going to set up one of its six Co-location Centres in Otaniemi, Espoo. The primary goal of the Centre is to generate new business activity, and provide education to entrepreneur-spirited students and professionals in the field of sustainable production and the use of raw mineral materials.

Other partners in the project in addition to VTT are Aalto University, the University of Oulu, the Geological Survey of Finland (GTK), Lappeenranta University of Technology, Outotec, Metso, Spinverse and FIMECC.
