Sarlux cares for and protects the land

Protection of the soil and subsoil

In 2017

37% of our storage tanks were equipped with a double bottom

53.2% of the tank containment surface was insulated fully from the soil

70,720 m2 of ground beneath the pipeways was paved

Under normal conditions, there is no possibility of contamination of the soil and subsoil, which could only occur in the event of accidental spillage of liquid hydrocarbons (raw materials, semi-processed materials or final products). Spillages might affect, in particular, product storage areas and the areas beneath the pipelines connecting the plants, the storage tanks and the jetty.

Safeguarding public health

In November 2013, after completion of site characterization, the “absolute risk analysis” was completed. This is a quantitative assessment of the risks for human health from the presence of pollutants in environmental media.
In March 2015 the Ministry of the Environment approved the risk analysis and requested the submission of a soil remediation project. The project was presented in early 2016 and received preliminary approval from the Interdepartmental Conference; activities will begin as soon as the final approval is issued.
In March 2018, Sarlux submitted a study on the procedure to assess applicability of Environmental Impact Assessment to the operational safety and soil remediation project.

The Characterisation Plan

Site characterisation activities have been launched using a number of techniques:

ground coring, to extract soil samples at depths of 5 – 10 m, in order to establish subsoil stratigraphy, detect any polluting agents and measure their concentration

piezometer sampling: extraction of samples at depths of 10 to 20 m, in order to reach the water table and test groundwater conditions

gas surveys, conducted to detect any hydrocarbon gases in the cracks and spaces in soil

topsoil surveys, by taking samples of the top 10-15 cm of soil from 10% of the survey points.


The Site Characterisation Plan, completed in 2010, involved 879 soil samplings, 144 piezometer samplings and 539 gas and topsoil surveys.
The Plan was submitted to the control authorities.


Sarlux has long carried out remediation at its site.
Back in 2004, we defined, with the Ministry for the Environment, the Sardinian Region, the Province of Cagliari, Local Health Authority (ASL) no. 8 and the Municipality of Sarroch the methodology for developing the Characterisation Plan, which comprised a plan of surveys on the site’s soil and groundwater to establish their status and plan any appropriate environmental and public health protection actions.

The key actions under the Plan were: performance of the planned surveys, implementation of emergency safety measures (MISE) through the construction of a dynamic water-extracting barrier, implementation of operational safety measures (MISOP) through the construction of a physical barrier on the seafront, and a remediation project on selected hotspot areas.

Our waste management policy aims at maximising recycling.

Our facility also generates urban solid waste, mainly from the office and canteen facilities. This is handled with a sorted waste collection scheme, in cooperation with the municipality of Sarroch. Over the past years we have steadily reduced the amount of non-recyclable waste thanks to staff awareness campaigns. The data for 2017 compared to 2016 confirm this trend.
The sorted collection of plastics, glass and paper, active since 2006, went from 24.3% of total urban solid waste in 2016 to 25.9% in 2017.
Including food waste, the share of sorted waste is 36% of the total, while non-recyclable waste amounts to 64%.

Sarlux was also able to reduce the production of special waste by 11% in 2017 compared to 2016.

In compliance with the current laws on hazardous waste production and disposal, since October 2013 Sarlux has been using the waste traceability control system (SISTRI).

Sarlux provides at no charge bilge water disposal services to the tankers docking at its marine terminal and to the ships
that send their bilge water from all Sardinian ports in tanker trucks..
