Dr. Pierre Côté is an engineer and a prolific inventor with over 100 patents. He has led the development of several products and processes in the field of water treatment. Dr Côté is the principal inventor of ZeeWeed®, one of the most successful membranes for large scale water and wastewater treatment. In 2021, Dr Côté developed an interest in microalgae and their multiple applications. What started as a hobby project led to the discovery of a new, intensive process to grow algae in a biofilm. This led to the creation of AlgaFilm Technologies Ltd which is focused on the development of a next generation process for wastewater treatment.

Ahren Britton is an experienced wastewater treatment and fertilizer product development executive. Mr. Britton was a founding member of Ostara Nutrient Recovery Technologies Inc, and inventor of the Pearl® wastewater treatment technology and Crystal Green® fertilizer product lines. He led the product development of both from lab to international commercial sales. This experience led Mr. Britton to develop a passion for product development in the wastewater and AgTech industries with a particular focus on nutrient management and resource recovery. In 2023, this passion led him to join with Dr. Côté to found AlgaFilm Technologies Ltd. with a view to accelerating the development of his innovative algae based wastewater treatment technology.

Steven Pedersen is an experienced and creative design Engineer in the membrane product sector. He has a passion for finding innovation solutions to waste and recycle problems.
