Watch the full footage of our 4th Free Webinar, held on 14th March 2024, and dedicated to the powder metallurgical technology behind some of the work in START, namely to produce the thermoelectric materials from the tetrahedrite-containing minerals, and the assessment of their properties. This was the agenda of the session:

Webinar “Powder technology for tetrahedrite p-type semiconductors“, 14/03/2024, 15:00 CET

• 15:00 Bruno Vicenzi (European Powder Metallurgy Association) and Filipe Neves (LNEG) – Welcome and introduction

• 15:05 Serena Busatto (MBN Nanomaterialia Spa) – “Mechano-chemical synthesis of thermoelectrically-optimized tetrahedrites from mine tailing”
• 15:40 Damian Karpowicz (GeniCore Sp. Z. o.o.) – “U-FAST – devices for SPS technology”
• 16:15 Patricia Almeida Carvalho (Sintef AS) – “Assessing the stability of novel tetrahedrites produced by powder metallurgy”

• 16:50 End of webinar

This video footage is an excerpt from an internal workshop on Life Cycle Assessment that was held in June 2023 by 3drivers (speakers were Eduardo Santos and Ana Braga) as a basic training for other consortium members, with the goal of creating a common ground among partners for the subsequent environmental impact assessment activities that START will carry out on the thermoelectric solutions that will be delivered.

The video is related to the general introduction given by E. Santos on the basics of the LCA approach and applications. It may be useful to you if new to the topic.

Watch the video of the presentations given by some of the START geology partners in the third START webinar, titled “Sustainable Solutions to Unlock the Potential of Thermoelectrics and Secondary Materials” (Madrid, Spain, 31st May 2023).

The three speeches give a nice cross section of the situation, indicating the potential for recovery of sulphides (tetrahedrites, and others) for our project, to transform them into thermoelectric devices. At the end, the speakers held a common Q&A time.

• Piotr Lipiarski (GeoSphere Austria) and Thomas Unterweissacher (Unterweissacher) – “Tennantite and tetrahedrite from two Austrian mine waste sites“
• Concepción Fernández Leyva (IGME-CSIC) – “Tetrahedrite Deposits in Spain“
• Stanistav Šoltés (Štátny geologický ústav Dionýza Štúra) – “Tetrahedrites from Mária Mine, Rožňava, Slovakia“
• Q&A

Watch the video of the presentation by Julie Hollis (EuroGeoSurveys), member of our Scientific Advisory Board, given in the third START webinar.

Julie’s presentation is about “The role of EuroGeoSurveys in supporting the EU’s ambition to boost domestic critical raw materials supply from secondary resources including mine waste“, that is one of the objectives of our project, namely introducing tetrahedrites from mine waste instead of Te-based thermoelectric materials.

The third START webinar was held on 31st May 2023 from our Annual Meeting in Madrid, and was titled “Sustainable Solutions to Unlock the Potential of Thermoelectrics and Secondary Materials“.

Watch the video of the presentation by Doug Crane (DTP Thermoelectrics), member of our Scientific Advisory Board and first speaker of the third START webinar, titled “Sustainable Solutions to Unlock the Potential of Thermoelectrics and Secondary Materials” (Madrid, Spain, 31st May 2023). Doug’s speech is about “Thermoelectric energy harvesting: principles, challenges and opportunities“, and covers the topic that is our main project focus, thermoelectricity and how to use it to harvest wasted heat into electricity.

Here is the full recording of the second START webinar, that was held on 26th April 2023, 16:00-17:15 CEST. The event hosted the following presentations:

• “Introductory remarks” – F. Neves (LNEG) – Project coordinator
• Fredy Guzmán Martinez, head of Environmental Projects of the Servicio Geológico Mexicano (Mexican Geological Service)
  “Critical raw materials in mining environmental liabilities: A review”
• Rafael Bittencourt Lima, geological researcher at CPRM – Serviço Geológico do Brasil (Brazilian Geological Service)
  “Tetrahedrite as an accessory mineral in Brazilian mineral deposits”.

The presentations were followed by a Q&A and discussion.

Here is the full recording of the first START webinar, that was held on 28th February 2023, 14:30-15:30 CET. More than 60 participants attended the event, that hosted two presentations:

• “Overview of the START project” – F. Neves (LNEG) – Project coordinator
• “The challenge of collecting uniform samples for use in the START Project” – Daniel P. S. de Oliveira (LNEG)

The presentations were followed by a Q&A and discussion.

On 10th November, Ester Boixereu i Vila (IGME-CSIC) gave a presentation in Spanish on the START project at the headquarters of the professional association of Spanish geologists (ICOG), in Madrid. The conference, whose title in English would be “How to generate electricity from mining tailings”, was part of an event called Semana de la Ciencia y la Innovación (Science and Innovation Week) in Madrid. This week “is an event for scientific dissemination and citizen participation organized by the Community of Madrid through the Foundation for Knowledge Madri+d whose objective is to actively involve society in research processes and development in science, technology and innovation”, and is aimed at the general public. You can rewatch the presentation here, from the ICOG YouTube channel.
