A project launched in New Zealand plans to turn hemp seed waste into high-value products for local consumption and export.
Hemp seeds are a superfood rich in protein, vitamins, minerals, fiber and beneficial fatty acids. Hulls are their hard outer coverings. After processing, seeds are placed in a pool where hulled kernels sink and hulls float.
In Australia and New Zealand, the article describes hulled hemp seeds and cold-pressed oil as the only legally permitted hemp seed food products. These countries, with significant production capacity, are developing plans for substantial quantities of waste that currently have no market.
Taranaki-based Greenfern Industries, which grows hemp in Central Otago and Taranaki, announced it will work with Callaghan Innovation and Hemp Connect on a project funded by the Bioresource Processing Alliance (BPA) to reuse hemp seed hulls.
Managing director Dan Casey said: “We have rapid expansion plans, so we are keen to create value-added opportunities for by-products of hemp seed processing. Given our commitment to sustainability, we are excited to be part of this research and development project.”
Hulls and other seed components could be used in products such as antioxidants, oil, protein supplements and water-soluble hemp protein. Other potential positive outcomes include more efficient processing, improved yields and less waste.
The project also received NZ$145,000 in cash from BPA, funded by New Zealand's Ministry of Business, Innovation and Employment.
