The purpose of ETVA is to hold minority shareholding of proven viable enterprises with high domestic value added. It prioritizes enterprises using technologies and, in general, production processes that are widely used either within the country or abroad, and which are classified in this sense as being mature. A significant criterion for ETVA so as to invest in a business is that the conditions of viable and sustainable development are met. This criterion is met if the enterprise which ETVA considers as a candidate for investment registers –by means of the technology and the overall production process it has chosen– elevated social and environmental indices, compared to other appropriate technologies.
