Fifty years ago, on 10 July 1976, the explosion of reactor A101 at the ICMESA plant in Meda (Milan) released 2,3,7,8-TCDD, known as “Seveso dioxin”, into the environment. It was the world’s most severe case of contamination by this substance and marked a definitive turning point in the global perception of environmental risk, contributing to the first European Directives on

A SEA Marconi acaba de concluir um tratamento de desalogenação (executado on-load, com o transformador energizado e sob carga) numa central hidroelétrica na Roménia. Estas atividades são rotineiras para a SEA Marconi, que realiza diariamente, de forma simultânea, entre 20 e 25 tratamentos em transformadores em diferentes regiões do mundo. Neste caso específico, a intervenção foi realizada com sucesso apesar

O Ministério do Meio Ambiente esclareceu qualquer dúvida: até 31 de dezembro de 2025, todos os equipamentos que contêm PCB em concentração superior a 0,005% (50 mg/kg) e com volume superior a 0,05 dm³ devem ser desativados, descontaminados ou descartados. Essa clarificação, que veio em resposta a uma consulta oficial da Confindustria, valida a interpretação que a Sea Marconi já

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: Decontamination of PCB-ContainingLeia mais

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 technologyLeia mais

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 theLeia mais
