Optimizing Steam Pyrolysis Parameters for Biochar Production from Invasive European Buckthorn

This MITACS research project tackles two critical environmental challenges: the costly removal of invasive plants and the improvement of degraded urban soils. Municipalities currently invest substantial resources in removing invasive European buckthorn, which is often burned or sent to landfills, releasing stored carbon back into the atmosphere. Additionally, many urban soils are compacted and lacking in organic carbon, which impairs both water infiltration and soil respiration.

The project will expand opportunities for Senti Solutions’ Steam Pyrolysis technology, using it to convert European buckthorn into biochar—a charcoal-like substance that improves soil health. Unlike traditional burning methods, steam pyrolysis offers precise control over temperature and processing time, allowing for the creation of biochar with tailored properties. This targeted biochar can be particularly beneficial for urban soil restoration, as it improves soil water retention and aeration, both of which are essential for the growth and maintenance of trees in cities.

The MITACS intern will spend four months at Senti’s Guelph facility testing various processing conditions, measuring energy efficiency, and analyzing the quality of the resulting biochar. This research will establish production protocols for biochar that meet international standards for soil amendments, while also rigorously documenting the commercial viability of this waste-to-value approach.
