Corsica: operation to clean up biomedia, waste from wastewater treatment plants In total some 98. of these biomedias or “filter media”, that is to say more than 50 kilos, have collected on the beaches of marine protected areas on the Isle of Beauty, by commissioned agents from the OEC, the Collectivité de Corse and the Cap Corse et de l’Agriate Marine Nature Park, supported by several associations
For the president of the OEC, Guy Armanet, this morning clean-up aimed to “collect precise data to map and analyze the phenomenon” and “to constitute an appropriate and efficient legal dossier “in order, in the future,” to anticipate and prevent this type of pollution “.
This” substantial and substantiated legal dossier “p ourra “allow the OEC to file a complaint against the authors of these pollution”, added the association Global Earth Keeper, which also participated.
AFP “We would like that to stop”, insisted Mr. Armanet, specifying that this waste comes from the sea and therefore a priori from Italy.
These “biomedias” are “small circular plastic filters used since the beginning of the years 1000 in many stations of municipal or industrial purification (fish farming, stationery) “, specified the Mare Vivu association, participating in this operation:
Their role is to serve as a support for microorganisms which, by agglutinating therein, allow the organic matter to be degraded more effectively during the phase. of biological water treatment. According to its website, “several incidents” could have led to cases of pollution, especially during heavy rains which “caused overflows in treatment plants, wastewater taking biomedia with it”.
In February 2019, 40. biomedia had thus been collected on beaches of the lido de la Marana, south of Bastia, according to the association.
At the same time, the preliminary hearings for a trial for this type of plastic pollution at sea had started in Italy, in Salerno. Environmental protection associations had attacked officials of the municipality of Paestum and the company responsible for managing the municipal wastewater treatment plant following the dumping in the Mediterranean of millions of these filters in February 2000.
Hundreds of thousands of these plastic washers had washed up on the Italian beaches of Campania and as far as Tunisia and France, according to the Surfrider association.
