The report details the 'Lake Winnipeg Bioeconomy Project', which investigates the use of cattail (Typha spp.) as a sustainable biomass feedstock. Through pilot harvests at Pelly’s Lake, Manitoba, the study demonstrates that using a rotary disc mower with conditioning rolls improves harvesting efficiency and drying times, enabling the use of large square balers. The harvested biomass was processed into solid fuel cubes and biocarbon (biochar), with the latter showing a higher heating value (31.41 MJ/kg) than wheat straw biocarbon (23.75 MJ/kg). Nutrient analysis indicates that cattail ash can serve as a potassium-rich fertilizer, though its phosphorus is largely insoluble at neutral pH. The report estimates the total cattail biomass resource in southern Manitoba between 2.7 and 5.4 megatonnes per year.
