Glass production activities in Borma area, located in Acqui Terme, started in 1905 with “Il Vetro”, a public limited company. From 1920, this company merged with MIVA (Manifattura Isolatori Vetro Acqui) which originally produced general insulating material on this site. Later production changed to Pyrex glass, under license registered in the USA in 1915 to which MIVA had exclusive production rights in Italy. In the early ‘70s, MIVA was bought by Borma S.p.A., which enlarged and renovated the plant. The area occupied by the factory was increased in 1975 to around 50,000 sq. m. Production was divided into different lines:
− Hollow glass (bottles)
− Insulators made up of tempered and twice-cooked glass (Hardex)
− Cement glass (a construction material)
− Other products borosilicate glass for technical or laboratory usage (Pyrex).
The economic crisis which began in the early ‘80s slowly brought about the closure of the factory, which was finalized in June 1999.

Demolition and remediation of plant and storage tanks. Demolition of buildings. Remediation of soil contaminated by hydrocarbons and metals with removal of buried waste.

Project phases:
1. Historical reconstruction of the production processes
2. Existing plant buildings survey
3. Mapping of asbestos-containing materials
4. Chemical-physical characterization of industrial waste found on site
5. Site remediation design for removal of waste and soil contaminated by hydrocarbons and metals
6. Definition of operational protocols (air quality monitoring during works and groundwater quality monitoring)


Challenges met:
− Excavation partially below groundwater level required the creation of a containment and drainage system in the upgradient area
− Several residues found were classified as hazardous wastes
− Airborne contaminant management and treatment of demolition waste in a mobile plant
− Air quality monitoring campaign with chemical speciation of gaseous mixture
− Comparison of the concentrations of contaminants present with regulated professional exposure thresholds and consequent definition of operational procedures for risk management, both for remediation operators and for external receptors
