Lunchtime lecture series #38
The rapid development of mechanised tunnelling in the last decades has increased the tunnelling community’s focus on the environmental aspects of tunnel construction. The excavation carried out by using EPB (Earth Pressure Balance) machines often requires the use of foaming agents, specific products that are added to the medium intended to be excavated, in order to make the excavation process possible. The produced muck can be considered more than a simple “landfill material” and its re-use is strongly suggested in view of sustainable excavation and circular economy principles. However, the correct management process should be followed. This process should take into account the presence of the used additives in the mucking itself.
This instalment of the Lunchtime lecture series will focus on 'EPB tunnelling: environmental aspects and re-use opportunities of the conditioned muck' in collaboration with ITA-AITES WG15.
The episode will feature three lectures and will finish with a Q&A with all speakers. It will begin at 13:00 CET.
- The conditioning phase in EPB tunnelling and the issue of muck disposal - Prof. Carmine Todaro
- Environmental aspects of the conditioning phase, chemical profile of foaming agents and the biodegradation process: the Italian approach before muck re-use - Dr. Anna Barra Caracciolo
- Muck: raw material for industrial production; mineralogical and chemical analysis and its use on construction sites - Prof. Dr. Robert Galler
- Discussion and Q&A moderated by Dr. Nikolai Bobylev

PRINCIPLES, DESIGN AND APPLICATIONS OF SPRAYED CONCRETE
On the 1st, 2nd and 3rd October, over three half-days, a training session on ‘The principles, design and applications of sprayed concrete’ will be co-organised with Mexican Association of tunnels and underground space engineers.
The objective of this training session is to present a global overview of the development and use of sprayed concrete in soil and rock tunnelling. The training will provide all the necessary information for efficient design, quality control and application of sprayed concrete, with references to interesting case studies. The course will highlight the latest improvements in spraying equipment and technology. Certification issues for nozzlemen will be also presented.
Lunchtime lecture series #39

Managing risks, sustainability and innovation in rock tunnelling
ITACET training course at the WTC 2025 in Stockholm!
The WTC 2025 and the ITACET Foundation have the pleasure of inviting you to the ITACET training course that has become a traditional part of the annual World Tunnel Congress. The 2025 WTC training course will focus on 'Managing risks, sustainability and innovation in rock tunnelling' and will take place on the Friday and Saturday before the WTC, on the 9thand 10th
May 2025. The prime goal is to attract senior/young professionals as well as university students, with an interesting and useful programme and world class speakers. The issues discussed will be of interest to professionals internationally.
The program will begin with a focus on advanced risk management in tunnel construction, exploring the latest strategies and tools to mitigate uncertainties and optimize design processes. It will then examine the importance of sustainability in underground projects, discussing innovative methods to ensure that tunnelling practices are environmentally responsible and resilient.
