LE1 – Green Coatings for the conservation of Cultural Heritage
University of Parma (Italy)
I. Alfieri, L. Bergamonti
The activity shows the results of innovative green solutions applied on materials commonly used in Cultural Heritage, as stones, wood, ceramics, glass and paper. These water-based solutions are characterized by the use of safe and green reagents, as natural polymers, vegetal components and inert ceramics. Each treatment is intended to give peculiar properties to every specific substrate: for example, biocidal activity, protection against harmful insects, self-cleaning behavior obtained by the photocatalytic degradation of superficial pollutants or the superhydrophobic character of the surface, preventing the sedimentation of harmful substances.
LE2 – Evaluation of Nanostructured treatments for the protection of Agrigento’s stone through
laboratory ageing tests
University of Bari – IEMEST (Italy)
The activity is aimed at presenting the study carried on to evaluate the effectiveness of water based nanostructured products for the protection of Agrigento’s stone. The study demonstrates that different accelerated aging tests, coupled with physico-mechanical tests, could be considered a valuable tool for the study of the causes, processes and effects of degradation, also allowing the evaluation of the effectiveness of conservative treatments by reducing the risks of not appropriate choices.
LE3 – Performance evaluation of a green innovative consolidant applied on Cadiz Roman Theatre
University of Cadiz (Spain)
The activity will show the results of the application of an innovative consolidant on calcareous bioclastic sandstone called “ostionera” from the Cadiz Roman Theatre. The novelty of this product is that it does not contain any volatile organic solvent (VOC) in its composition, thus avoiding the environmental contamination that produces the evaporation of these compounds during the in situ application. Tests were carried out both on laboratory samples and directly in situ and results has been compared in order to evaluate the behavior of the treatment.
LE4 – Microbial and Natural products for green conservation ENEA (Italy) – El Colegio De Michoacán
During the living lab will be presented:
1) biocleansing procedures using bacteria (micro-packs).
2) Methods for control/removal of biofilm with natural products.
3) Nopal mucilagine as fixative and bio-mortar additive.
LE5 – Use of biotechnology in the conservation field: removal of sulphates on wall paintings with
sulphate-reducing bacteria and bioconsolidation of wall paintings and stuccos
E. Panella, C. Giovannone, M. Bartolini, V. Fondi
The activity will show a new system of biocleaning (Micro4Art+Kelcogel) that is suitable for vertical surfaces (wall paintings) and the M-3P product (patented by University of Granada) for bioconsolidation applications on wall paintings and stuccos.
LE6 – Green Rescue
B. Gianfreda, F. Damiani, A. Macchia
The Green Rescue is a new product by YOCOCU to remove protective resins (Dammar, Retoucher, PVA, Paraloid) using on modern and old paintings. The activity will show the efficacy of Green Rescue compared to others solvents with high dangerousness and environmental impact.
