Using Biochar and Wool Waste to Reduce Peat Moss in Greenhouse Production

Researchers at Assiniboine College are testing biochar and sheep wool waste as sustainable alternatives to peat moss in greenhouse growing systems. Because peat bogs are critical for carbon sequestration, reducing their harvest helps protect biodiversity and prevent carbon release. This project, supported by the Sustainable Canadian Agricultural Partnership, focuses on practical, scalable solutions for growers. By using cattail-based biochar, the study aims to maintain plant performance while lowering the overall carbon footprint of ornamental and nursery plant production.

Replacing peat is a huge win for carbon, but the real test is the cost. If these biochar and wool mixes cost more per cubic yard than peat, growers wont switch regardless of the environmental benefit. Hope they are tracking the price per unit.

That is why the S-CAP funding matters. It bridges the gap between a lab success and a commercial product. The goal here is to create a market where the sustainable option is actually viable for a business to buy.

Biochar is interesting for long term carbon storage. I wonder about the energy cost of the pyrolysis process used to make it from cattails. If the energy used to create the biochar is high, it might eat into the net carbon gains.

Good to see applied research focusing on the supply chain. Peat harvesting is a major carbon source that often gets ignored in favor of energy transitions. Using waste wool and cattails is a solid way to handle organic waste.
