National Center for Electrochemistry and Environmental Technologies (CNETE)

Collège Shawinigan, Shawinigan, Québec
Area(s) of Expertise

CNETE at Collège Shawinigan is part of Trans-tech’s network of technology transfer centres. Its mission is to contribute to the Mauricie region’s economic development by transferring electrochemical and environmental technologies. Its scientific impact, however, extends well beyond the region’s geographical boundaries. CNETE is known for its applied environmental research, especially in the areas of industrial bioprocesses, membrane separation technologies and electrochemistry. The fields of application of its projects are as follows:

  • Agrifood (beers and cheeses)
  • Biofuels (biogas, bioethanol, biobutanol and biodiesel)
  • Green chemistry (environmentally friendly cleaners, printing, antifreeze and insulation materials)
  • Pharmaceuticals (antiviruses, vaccines, antibiotics and probiotics)
