Funded Master of Science position in Soil Science

Increasing the value of grape marc waste material through biochar production and implementation

Grape marc is a carbon-rich waste material that can be composted and used as a soil amendment. This supports bio-circularity and is well-known to improve soil microbial activity and vine performance. However, the positive benefits of using compost as an amendment are short-lived, and the need to apply it frequently challenges the economic and environmental sustainability of the practice. Thermal decomposition of grape marc using pyrolysis yields biochar: a lighter and more stable form of carbon that resists microbial decomposition when used as a soil amendment. Current evidence suggests that grape marc biochar can provide a long-term carbon sink and aid with the physical and chemical conditioning of soils. However, research has yet to provide evidence of biochar’s advantages over compost treatments and examine thoroughly the net carbon footprint and economics of the respective practices.

This project will use laboratory incubations and greenhouse trials to determine the relative benefit of grape marc biochar over composting and carry out a targeted life cycle assessment to determine the total carbon footprint of producing grape marc-based biochar and applying it to soils. This project is supported by the Bragato Research Institute and Green Circle NZ, who contribute expertise, facilities and contacts in viticultural operations and biochar production.
