NAIT research project explores peat alternative to improve horticulture

A new NAIT Applied Research project is working to solve environmental concerns related to peat production. The goal is to find a way to replace peat with by-products from farming or agriculture activities that aren't currently being used. 

The project is supported by Scotiabank's net-zero research fund and is a team effort with Plantae Technologies, a company based in Alberta. The project aims to help local businesses and Indigenous communities by creating a new revenue stream for waste products.

Environmental impact 

Peat improves soil quality and plant growth, though gathering it poses significant environmental challenges. The mining of peatlands releases substantial amounts of carbon dioxide into the atmosphere, as this landscape ats as a natural carbon sink. NAIT's Applied Research project hopes to mitigate that impact by utilizing leftover materials from hemp, barley, wheat, and canola harvests to create a replacement for peat, allowing the natural carbon-sink to be left alone. 

"Our current target would be replacing a portion of peat usage," says Dr. Justice Asomaning, Applied Reseach Chair at NAIT. "If we were to replace up to 20 per cent, that would be a huge success." 

Research project 

The research will include side-by-side comparisons of plants grown using traditional peat versus plants grown using the new alternatives. Results from the study are anticipated in September, with a target of replacing up to 20 per cent of peat usage by the end of the project, marking a significant step toward sustainable horticultural practices. 

In partnership with the Metis Settlements Development Corporation (MSDC), Plantae Technologies hopes to commercialize the peat alternative based on the findings from NAIT.  Reports indicate there is a growing demand for peat, with Canadian exports reaching approximately 1.3 million tonnes valued at $490 million in 2023. The market potential for this innovative solution is promising.
