The restoration of mine sites represents a significant environmental challenge. This project seeks to improve the restoration of graphite mine sites by optimizing the quality of the soil used.
To restore mine sites, forest residues and topsoil from mining operations are stored as windrows, which are large piles of soil and organic matter. Our research analyzes these windrows to determine the best combination of residues and topsoil that will generate more fertile soils best suited to ecosystem regeneration. We will use metabolomics to study molecules in the soil and understand the biological processes at play. By combining these data with microbial diversity information, we will be able to identify treatments that improve residue degradation and soil quality.
The results will help mining companies, such as Nouveau Monde Graphite, choose best practices for ecological restoration, thereby reducing costs and promoting carbon sequestration, which, in turn, will contribute to Québec’s carbon neutrality.
