Ontario is investing $5.5 million in Thunder Bay based Greenwater Technology to support the production of renewable diesel and sustainable aviation fuel from forest biomass.
The company is converting part of the Thunder Bay Pulp and Paper site for biofuel production, with funding provided through Ontario’s Forest Biomass Program and the Northern Ontario Heritage Fund Corporation.
The project centres on a pilot plant that will convert forestry residuals and mill by-products into renewable fuels, helping mills extract more value from underutilized biomass. It also aims to reduce waste across the fibre supply chain while improving overall biomass use.
Over time, Greenwater plans to integrate the technology within the Thunder Bay mill, enabling on site biomass processing and improved operational efficiency.
The investment reflects Ontario’s broader push to diversify forest-sector products, strengthen mill competitiveness and expand into emerging low-carbon fuel markets. Sustainable aviation fuel is gaining traction globally as transportation industries accelerate decarbonization efforts.
If successfully commercialized, the project could give the mill a new way to monetize residual biomass while expanding the sector’s role in renewable fuel production.
Greenwater Technology is focused on developing technologies that convert forest biomass, mill residuals and underutilized wood fibre into renewable diesel and sustainable aviation fuel.
