Omschrijving

In Twente at 400 meters depth, there are several hundred giant cavities (caverns), which, from the beginning of the 20th century, have been formed as a result of the production of salt. It appears that 60 of these salt caverns were made too large. In these large caverns the risk of collapse and sink hole formation is high. How can we stabilize them? Is filling them with surplus hazardous residues from waste incinerators, so that the knife cuts both ways, an option? Unfortunately, no experience exists worldwide in the use of hazardous residues from waste incinerators for the stabilization of salt caverns. All hazards, uncertainties and costs should be clarified, and stakeholders have to be well informed.

In the afternoon a series of open lectures are given, followed by short introductions and a debate in the framework of Studium Generale during the evening.

This exchange of knowledge and debate by experts and stakeholders is in the interest of the social decision-making process concerning the use of the underground as storage for hazardous waste. This decision is expected to be made later in the year with a public consultation on the amendment of the development plan “Boeldershoek”.
