Following the interventions and discussion among the participants:

- The extractive industry is essential in the development of today's society. The modern man depends more and more on the exploitation of mineral raw materials. The importance of the extractive industry in the national economy is manifested particularly in the export sectors, contributing decisively to Portugal's wealth.

Finally, and also in the context of the intervention by ANIET's General Director, it was launched a challenge to the participation of the national companies in the different international fairs, so as to boost their export market. It were underlined the opportunities to support the expansion and internationalization of companies that operate in the sector. ANIET is the privileged partner to channel these supports with its members.

- Portugal possesses a diversified mineral potential, naturally associated with the geology of its territory, whose quantitative expression points out the realistic possibility of the sector to aim to double the GDP contribution, an objective which, however, needs to be supported by sectoral policies of positive discrimination, such as fiscal policy, access to venture capital or even investments in research projects and scientific and technological development.

 - In a particularly interactive session, there was the opportunity to attend to an accident simulation and to the demonstration of the due procedures in these cases. This simulation, carried out by the Somincor Intervention Group, has made us aware of the excellent level that this intervention group already shows.

Having been presented the major conclusions that emerged from the meeting of the partners which integrate the Global Information Network on Aggregates, it is noted that the members of this network represent more than 60% of the aggregate world production, estimated at more than 40 billion tons. It were pointed out the data on world production and consumption of aggregates, the prospects of the global evolution of the markets of these raw materials, and the future challenges to this important sector of the world economy. The problems and the need to plan the access to these mining resources were clearly identified, combating not only the illegal activity but also the environmental impacts that deregulated practices impose on the sector of the extractive industry.

- It was reflected on the sustainability in the aspect of the resources' preservation, identifying the different dimensions of this sustainability in the Mineral Row. It was emphasized the importance of the trinomial KNOWING - PRESERVING and VALUING the mineral resources.

Facing the increase in the consumption of raw materials, it was highlighted the need to resort to marine mineral resources in the medium term. It is imposed a national research policy that allows us to better know what we have, how much we have, and where we have it.

It was highlighted the need to impose, for the sake of transparency, materiality, competence and impartiality, norms and rules in the elaboration of reports with the results of prospecting and research of geological resources.

Given the advantages of looking at the Extractive Industry from the perspective of the Circular Economy, and how this new paradigm is cherished by the policies of the European Economic Community, some practical cases of waste recovery (which are now justly classified as by-products) have also been illustrated and may constitute new business opportunities for the companies of the sector.
