SEA Marconi has just completed a dehalogenation treatment (performed on-load, with the transformer energised and under load) at a hydroelectric power plant in Romania. These activities are routine for SEA Marconi, which performs 20 to 25 transformer treatments simultaneously every day in different areas of the world. In this specific case, however, the intervention was successfully carried out despite particularly

The Italian Ministry of the Environment has removed all doubt: by December 31, 2025, all equipment containing PCBs in concentrations greater than 0.005% (50 mg/kg) and with a volume > 0.05 dm³ must be taken out of service, decontaminated, or disposed of. This clarification came in response to an official inquiry from Confindustria, Italy’s main industry association. It confirms an

  On May 27, 2025, the CEI – Italian Electrotechnical Committee hosted in Milan a technical seminar titled: “Dielectric liquids for transformers: from mineral oil, through PCB, to esters”. Sea Marconi took part as a sponsor and speaker, offering a perspective that bridges the past and future of asset and risk management for transformers. The first presentation, by Vander Tumiatti,

The first "episode" of this important milestone dates back to May 2020 with the publication of the call for tenders by The Egyptian Environmental Affairs Agency (EEAA) through the agency for the sustainable management of persistent organic contaminants (POPs) in response to the obligations of the Stockholm Convention. www.popsegypt.com The tender, financed by the World Bank / GEF, was entitled: DecontaminationRead more

Even Iran has put the PCB problem “on the agenda”: a special analysis was in fact dedicated to this topic during the “POP’s management workshop” held on 9 November in Tehran. The Iranian Ministry of the Environment and Industry is currently exploring the different solutions for management (inventory, decontamination, disposal) of the PCB problem; several international operators attended the meeting, eachRead more

The first relations between Sea Marconi and Vietnam date back to 2003, when a technological cooperation agreement was signed on “Clean Technologies” between the European Commission and Asian area. Twelve years later, last 11th and 12th May 2015, we were pleased to host a delegation of the Vietnamese national electricity company, EVN*. Their objective was to select the best technologyRead more

We are particularly proud to be able to recount another positive update in the “PCBs free Program for Japan” project: the arrival of the first order for the development of a system (DMU) for the dehalogenation of oils and transformers contaminated by PCBs. To completely understand the extraordinary nature of this news, we need to take a look at theRead more

Scenario Hydro Power Plant The transformer is located near a river dam with extreme logistical and environmental constraints. The option of changing the oil was discarded immediately because of the enormous difficulties in handling (see. Photo) around the transformer. At the same time the fuller earth techniques would not solve the functional criticalities of the system “oil – transformer”. NameplateRead more

For Sea Marconi 2013 ended with very interesting outlooks; one of these involves the opportunity offered by Mexico, engaged in the project for the destruction of PCBs: Environmentally Sound Management and Destruction of PCBs in Mexico. The project, started in 2009, involves the joint effort by the Ministry of Environment and natural resources (SEMARNAT), the Ministry of Foreign Affairs, UNDP (United NationsRead more
