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

As part of the PCB/UNDP/GEF project, Sea Marconi has been invited to present its solutions at the workshop on PCB/POPs treatment (decontamination and disposal), which will be held on 21st and 22nd July 2015 in Brasilia (Brazil). The event will see managers and technical experts gathered together from the energy, industrial, transportation, health, agricultural and other sectors, which all use electrical equipmentRead 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

In mid-December 2013, Sea Marconi responded with pride to the invitation to go to Russia to offer support in managing the PCBs problem, with respect to the Stockholm Convention. The activity was born under the auspices of UNIDO, but a local operator already exists charged with the development of a pilot project on the contaminated (and non) equipment of the railway network of theRead 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
