Capping
Installation of an impermeable cover over landfill sites and/or polluted areas.
Characterisation
Detailed chemical/physical analysis of potentially polluted areas.
CTC
Contamination Threshold Concentrations, levels of environmental matrix pollution above which site characterisation and site-specific risk analysis are required.
Decommissioning
The act of closing, reclaiming and demolishing industrial plants.
Draining trench
Excavations which enable the capture or disposal of water from/into surrounding soil, filled with natural and highly permeable inert materials (gravel or quarry debris).
Draining trench
Excavations which enable the capture or disposal of water from/into surrounding soil, filled with natural and highly permeable inert materials (gravel or quarry debris).
Emergency Safety Containment Barrier
A hydraulic barrier (system of wells for the pumping of groundwater), or a physical barrier (sheet piling, impermeable area, etc.), installed for the emergency safety containment of the polluted Site or Area
ORP
Operative Reclamation Project.
On site technology
Reclamation systems consisting of equipment dislocated throughout the site and which treats soil/water, without requiring removal from natural location.
Off site technology
A reclamation method involving the removal/extraction of the environmental matrix and its treatment in plants beyond the site
On site technology
A reclamation method involving the removal/extraction of the environmental matrix and its treatment directly at the site
Pumping
Aspiration and extraction of groundwater.
Photovoltaic
A plant which generates electric power from solar energy.
Permanent safety containment
Containment works at a site designed and implemented as a definitive reclamation operation.
Percolated substances
Liquid normally caused by the infiltration of water into a mass of waste or by the decomposition of waste.
Phytoremediation
Reclamation technique involving the use of plants for the treatment of contaminated environmental matrices.
Piezometer
An instrument which is placed vertically into the ground using a probe to measure water pressure in an aquifer.
Pump & treat
Combined system for groundwater extraction and treatment.
Risk Analysis
Health risk analysis enables the quantitative assessment of risks to human health connected to the presence of pollutants in environmental matrices, and the definition of reclamation objectives.
RTC
Risk Threshold Concentrations, levels of environmental matrix pollution above which site characterisation and site-specific risk analysis are required, as specified in Annex 5 to the fourth part of this decree.If the potentially contaminated site is located in an area affected by anthropic or natural phenomena which exceed one or more contamination threshold concentrations, said concentrations are taken to be equal to existing background values for all exceeded values.
- Risk Threshold Concentrations (RTC): the contamination levels of environmental matrices, established on a case-by-case basis, with the application of a site-specific risk analysis procedure in accordance with principles illustrated in Annex 1 to the fourth part of this decree and on the basis of characterisation plan results; if exceeded, safety containment and reclamation are required.Concentration levels defined in this manner constitute acceptability levels for the site.
Revamping
Operation involving the review and restructuring of industrial plants with the purpose of increasing the useful life of facilities in the production process.
Sheet piling
Sheets, normally made from metal, which are driven into the ground at various depths to create separation or support barriers in the event of selective excavation operations.
SIN
Site of National Interest.
Topsoil removal
Removal of topsoil.
TAF
Groundwater treatment

SITES
ASSEMINI
Sustainable environmental cleanup, industrial requalification inspired by historical-naturalistic promotion are drivers of the Eni Rewind strategy for Assemini.
CONTINUE READINGAVENZA
The former Agricoltura plant in Avenza occupies 17 hectares and is located in the Apuan industrial area of Avenza, in the Carrara municipality, within the Massa Carrara Site of National Interest.
CONTINUE READINGBRINDISI
The Brindisi Site of National Interest is located south-east of the city, on the Adriatic coast and in total consists of more than 11,500 hectares of land and marine areas. It contains the multi-company petrochemical plant which was commissioned in the late fifties.
CONTINUE READINGCASSANO CERCHIARA
At the Cassano and Cerchiara sites, located in the Crotone - Cassano and Cerchiara Site of Natural Interest, since 2008 Eni Rewind has been committed to operations for the removal and disposal of soils mixed with zinc ferrites.
CONTINUE READINGCENGIO
The requalification of a centenarian production plant which first opened in 1882, as a small dynamite manufacturing plant for the production of explosives, to support the war industry at the time.
CONTINUE READINGCROTONE
Eni Rewind, extraneous to the industrial activity which determined the environmental state of this site, immediately undertook emergency containment measures for the protection of soil and aquifers.
CONTINUE READINGFERRARA
Activity at the Ferrara site first began with the commissioning of a plant for the production of synthetic rubber, by Società Anonima Italiana Gomma Sintetica.
CONTINUE READINGGELA
The symbolic starting point of our sustainable development challenge, the Gela Site of National Interest extends over 795 hectares of land, approximately 17 of which are owned by Eni Rewind and approximately 55 managed on behalf of ISAF.
CONTINUE READINGMANFREDONIA
Since its commissioning in the mid fifties, the multi-company plant in Mantua has been one of Italy's most important petrochemical industrial sites.

CONTINUE READINGPIEVE VERGONTE
Its delimitation, as defined in Environmental Ministry Decree dated 10th January 2000, includes the area of the industrial site, divided into internal and external areas, a part of the Toce river and the Pallanza bay on Lake Maggiore.
CONTINUE READINGPORTO MARGHERA
In the Venice-Porto Marghera Site of National Interest, Eni Rewind owns approximately 208 hectares and to date, has spent over 208 million euros for the demolition of decommissioned plants, soil and aquifer reclamation activities.

The plant was built in 1962 by S.I.R. - Società Italiana Resine, thanks to grants provided for by the Sardinian Rebirth Plan, which accompanied the Island's industrial development.
CONTINUE READINGRAVENNA
It is said that Enrico Mattei strongly desired the large petrochemical area in Ravenna. Upon returning from a visit to a synthetic rubber plant in America, Eni's first ever chairman, then Ente Nazionale Idrocarburi, decided to import the technology to his country.
