In artworks under xilofagus insects attack, we apply an efficient disinfestation method, simultaneously non-invasive, non-toxic and ecologic: anoxy. Using Oxigen (O2) scavengers or inert gases such as Nitrogen (N) and Carbon Dioxide (CO2), this solution consists of closing the artworks in a multi-layer plastic “bubble” for about 25 days.

Surveying the suitability of a building to host a collection is essential to ensure its preservation.   The 10 risk agents defined by the  Canadian Conservation Institute (CCI) were the framework we used to analyse exhibition and stock rooms, both at the European Parliament and at the  Municipal Museum of Penafiel.
