Greenov, a Young Innovative Company created in January 2021, is a SAS with a mission that seeks to innovate to reduce the impacts of human activities on the maritime environment. Greenov is targeting four main areas:- The reduction of underwater noise pollution generated by noisy marine work (pile-driving, dredging, rock removal...) in coastal and offshore areas, with our solution the SubSea Quieter: a device consisting of an air-filled membrane that drastically reduces sound waves. - Reducing accidental collisions between large cetaceans and ships; - Preventive treatment of biofouling on ship hulls; - Monitoring the impacts and pressures of visitor numbers and tourist activities on sensitive habitats, using intelligent sensors (cameras and hydrophones). Greenov is positioned as a relay between scientific research and the needs of economic and public players. With a resolutely innovative approach, Greenov aims to be a technological gas pedal for maritime Cleantech. Greenov is already heavily involved at European level, having taken part in 5 European projects since its creation.
