Pulp and Paper Mill Partners with Rock Tech Lithium to Pilot Innovative Lithium Processing Method
Thunder Bay Pulp and Paper has partnered with Rock Tech Lithium to test an innovative lithium processing technique that utilizes crude tall oil, a byproduct generated during pulp and paper manufacturing. The pilot project is supported by a $262,500 investment from the Government of Ontario and aims to evaluate the feasibility of using this renewable byproduct in lithium extraction over the coming months.
The initiative forms part of Ontario’s broader strategy to strengthen northwestern Ontario’s critical minerals sector and prepare the region for future developments associated with the Ring of Fire. By integrating resources from the forestry and mining industries, the project seeks to create a more sustainable and locally connected supply chain.
According to Kevin Holland, Ontario’s Associate Minister of Forestry and Forest Products, the collaboration represents a significant opportunity to expand the value of forestry byproducts while supporting the province’s growing mining industry. He noted that the project could diversify the commercial applications of mill residuals and forestry biomass, creating benefits for both sectors.
Although the pilot is still in its early stages and no long-term commercial agreements have been confirmed, a successful outcome could pave the way for regional supply chains that connect pulp and paper mills with lithium production facilities. Such integration has the potential to generate new economic opportunities and strengthen industrial collaboration across northwestern Ontario.
Dirk Harbecke, Chairman of Rock Tech Lithium, highlighted the natural synergy between the pulp and paper and lithium industries, explaining that utilizing underused forestry byproducts can improve operational efficiency while supporting regional manufacturing. He emphasized that establishing local supply chains would benefit both industries and enhance the sustainability of lithium production.
Rock Tech Lithium is currently advancing plans for two lithium mining operations and two processing and conversion facilities in northwestern Ontario. The company expects to commission its first Ontario lithium mine by 2028, followed by its first lithium converter near Red Rock in 2029.
Once fully operational, the projects are expected to create around 300 direct jobs in mining and mineral processing, while also generating additional employment opportunities across transportation, food services, infrastructure, and other supporting industries, contributing to the region’s long-term economic growth.
