The material, which is available in the economy of the country, may be either consumed in it (DMI - Domestic Material Input) or exported, either as raw materials or finished products. After deducting exports from direct material inputs (DMI), remaining materials represents domestic material consumption (DMC). In 2019 DMC in Slovakia was 67 022 thousand tons, which represents 12.3 tons per capita (13.3 tons per capita in the EU-28). In the period 2005-2019, there was the DMC decline by 12%. This development trend is- in terms of efficient use of natural resources- perceived as positive, as the development of material consumption presented as the sum of imported materials, extracted minerals and collected biomass obtained in Slovakia after subtracting the exported materials, does not record a major increase in the current economic growth, so when comparing to GDP growth, we can speak about relative separation of curves of material consumption and GDP.
An important predictive value is also the size of import share in the DMC. The bigger the share ratio, the more sensitive is the country economy to random fluctuations in foreign trade (lack of certain commodities, unexpected increase of their prices, etc.). The share of imports in DMC increased from 50.3% in 2005 to 67.3% in 2019, which means increasing rate of the Slovak economy dependence on imported raw materials.

A more detailed view at the composition of DMC
provides an impression of the importance of various materials and their possible potential for their recovery. In 2019, DMC in Slovakia consisted mainly of non-metallic minerals (50.2%), followed by biomass with 27.4%, of fossil energy materials (18.5%) and metal ores with 3.9%.
