EDM was invited to participate in the technical meeting organized by the International Atomic Energy Agency (IAEA) about “Remediation of Groundwater in Uranium Mining Operations“, held from 14 to 18 May 2018 in Prague, Czech Republic. The objective of the meeting was to obtain input and lessons learned from representatives of several IAEA Member States with their own experience in groundwater management in uranium mining operations for the preparation of a new IAEA Nuclear Energy Series report, which addresses, among other issues, the environmental remediation strategies that can be implemented.

The meeting included a visit to the state-owned DIAMO company responsible for eliminating the consequences of mining activities in the Czech Republic, including the development of environmental remediation interventions. The field visit to one of the most significant environmental impacts in the Czech Republic was carried out, following uranium exploration through in-situ leaching, in the Straz pod Ralskem area, which provided the knowledge of the environmental remediation strategy in course.

EDM presented its experience and case studies on the rehabilitation of abandoned mines in Portugal and the work carried regarding the water resources monitoring plan and the active mine water treatment systems and, more recently, the passive mine water treatment systems already implemented.

On 25 May 2018, EDM registered its commitment to the implementation of the General Data Protection Regulation (GDPR), through a “AWARENESS” session to all its employees, including via Skype ®, to the localized ones in Urgeiriça.

EDM participated in the 2nd PhytoSUDOE Stakeholder Workshop, which was held on 17 April 2018 at the School of Biotechnology of the Portuguese Catholic University, in Porto.

The PhytoSUDOE – “Demonstration of the improvement in soil biodiversity, functionality and ecosystem services through phytomanagement in contaminated and degraded soils within the Interreg Sudoe area” project, in which EDM participates as stakeholder, has as its main objective the management of contaminated and/or degraded sites and their recovery through the application of phytoremediation technologies that improve biodiversity and ecosystem functionality and promote the sustainable use of resources.

EDM presented its experience and case studies relating to the rehabilitation of abandoned mines in Portugal, and some works carried out in the field of land restoration.

EDM was present at the Portugal Smart Cities Summit 2018 which was held at the Lisbon Congress Centre on 11, 12 and 13 April with the Green Business Week subscription.

Once again, EDM, together with entities related to Energy, Municipalities, companies, startups, academics and individual agents, participated in the discussion on the future of smart cities, sharing its sustainable, innovative and experienced approach in the sector of the mining resources of the Country, as well as of the increasingly important reclamation and environmental recovery of the old degraded mining areas.

On the 12th, Sharing Cities, the Smart Mobility Summit and the Energy Summit took place. The latter was attended by the Minister for Economic Affairs and the Secretary of State for Energy, in which topics were debated such as mobility and digital transformation of energy, and low-voltage concessions: Challenges of Low Voltage Network and Smart Cities and Energy 4.0: The Digitization of Energy and the Impact on the Network, Consumers and Society.

EDM participated in the Workshop “Scientific Technical and Legal Challenges of Deep Sea Mining – A Vision for Portugal” held on 16 April 2018 at the António de Almeida Foundation in Porto, under the WP-Legal project CORAL – Sustainable Ocean Exploitation: Tools and Sensors, a collaborative project by the INESC-TEC and CIIMAR.

The workshop was attended by national and international experts, policy makers and stakeholders from the most representative sectors and promoted a broad debate on current scientific and technological knowledge of prospection and exploitation of deep water mineral resources, potential environmental impacts and legislative context.

EDM joined the discussion panel on “Scientific and Technical Challenges of Deep Sea Mining – A Vision for Portugal”.

World Tree or Forest Day is celebrated annually on 21 March.

Partners in this initiative and in the context of the environmental restoration works of the former mining area of Castelejo, which contributed to the renaturation of previously degraded areas, several tree plantations were carried out on this day.

The Secretary of State for Energy, Jorge Seguro Sanches, stated that Portugal is “always highlighted as a very good example” in the environmental requalification of old uranium mines, a work that is carried out by EDM.

In Fornos de Algodres, Guarda, during the ceremony that marked the conclusion of the environmental remediation works of the Mining Areas of Castelejo, Formiga, Vale de Videira, Vales and Póvoa de Cervães, the Secretary of State stated that «this work is going very well».

The requalification works represented an investment of 3.7 million euros and Jorge Seguro Sanches said that Portugal will «continue to work in this field». «We wish it were faster, but we have to look at the means we have and at our limitations. The objective is to be as quick as possible so there are [European Union financiers] intended precisely for this objective», he added.

The Secretary of State reiterated that the Portuguese example is praised internationally and said that EDM has been sought by other countries «to know what can be known and what can be improved».

Environmental remediation works in the Castelejo, Formiga, Vale de Videiras, Vales and Póvoa de Cervães mining areas in the Guarda and Viseu districts included decontamination and sanitation of soil and soil heaps and landscape restoration works, among others.

Portugal has identified 199 former mining areas and restoration works have been carried out on 105, with a total investment of 80 million euros since 2001. The interventions in the remaining areas include an investment of 60 million euros, said Rui Rodrigues, president of EDM.

The Week of the Partners of the Guide of the Portuguese Geological and Mines Sites in 2018 will take place between 19 and 25 March, with several unique initiatives organized by the Partners, throughout the entire territory of the continent and the Autonomous Region of the Azores.

Be aware! Some initiatives require prior registration and others have access restrictions. But most are for the whole family!

Programme available here.

On 12 January 2018, EDM technicians, accompanied by the President, Vice-President and technicians from Castelo de Paiva Council, travelled to the former mining area of Pejão-Germunde, in Pedorido, in order to evaluate a situation of smouldering in the heaps that resulted from coal mining.

This situation occurred following the violent fires of 15 October that devastated much of the country and the Municipality of Castelo de Paiva, where they spread to the heaps of the former coal mines. Despite the fact that the fires were extinguished, the materials deposited in this heap, which contained carbon, continued to smoulder.

The main purpose of this visit was to carry out an on-the-spot assessment of the situation and assist in the joint definition of the measures necessary for its resolution.

As a result of the visit, EDM found that the focal points of the smouldering are limited to materials deposited in heaps, and there is no evidence that they have spread to unexplored coal deposits in the subsoil.

The slow combustion of carboniferous materials deposited in heaps is responsible for the emission of combustion gases from the coal, which became more intense with the rains as a result of a rise in the evaporation of rain water in contact with the focal points of the fires.

While considering that this situation does not immediately represent a reason for alarm among the population, EDM stresses that it has put in place an air quality monitoring station to measure carbon monoxide, nitrogen oxides, sulphur dioxide and particulates in order to clarify the impacts on the populations located in the surrounding area.

Additionally, despite the fact that the the focus points of the fire were located on private land, EDM has erected temporary fencing in areas that were not sealed off in order to guarantee safety.

These are urgent and necessary measures required to assess the effects on the populations of the “combustion outbreaks” and to prevent accidents in the affected areas. They are being implemented while a technical solution is carried out, firstly to extinguish the fires and then to make necessary adjustments to the heaps to avoid further occurrences in the future.

Within the scope of the INTERREG GEO_FPI Project: Cross-border observatory for the geo-economic recovery of the Iberian Pyrite Belt. On 3 November, the LNEG – National Laboratory of Energy and Geology and the Municipality of Aljustrel, as partners in the Project, and a group of professors and students from the University of Coimbra, visited the environmental remediation works of the former mining area of Algares and the remediation works of the former mining gallery below the Bairro Vale d’Oca district.

The hydrological-environmental rehabilitation of the Aljustrel Mining Complex took place in 4 stages and covered the mining areas of Algares, São João and Moinho, as well as the metallurgical area of Pedras Brancas. The investment made in the period 2005-2008 was co-financed by the Alentejo Region Operational Programme under the auspices of CSF III and the 2007-2015 Operational Programme for the Advancement of the Territory under the NSRF.

This former mining area has been visited by several entities, with Aljustrel Municipal Council organizing the local logistics.
