Regenerating Scotland’s hemp industry for health, climate, and a green economy

Research and knowledge exchange led by a research team at the Rowett Institute has underpinned a resurgence in the Scottish hemp sector. The researchers found hemp seed-based foods (oil and flour) to have an excellent nutritional profile with several health-supporting benefits. Taking the findings forward, the team were pivotal in creating a sector-wide association, to align and galvanise all aspects of the supply chain for a thriving hemp industry. Hemp grows well in Scotland while offsetting greenhouse gases and maximising biodiversity and the team have explored the potential of markets for Scottish hemp making clear recommendations to Scottish government.

The broad range of products offered from all parts of the plant—healthy food, materials, biofuel—supports a zero-waste circular green economy. By working directly with producers and processors, the team are regenerating the Scottish hemp industry as a tangible solution to directly address challenges in health, climate, and economy.

Annual carbon savings achieved with the initiative:

• CO2t savings 2022/2023: 3,847,500* CO2t.
• CO2t savings 2023/2024: 3,847,500* CO2t (Estimated)  *Based on 256,500 hectares (4.5% of hemp planted over Scotland’s 5.7 million hectares) and 15 CO2t directly absorbed for every hectare of hemp. 
• CO2t savings over the life cycle of the project: Much greater than the direct sequestration rate stated above. Additional savings in food miles (reduced import of soya bean; olive oil); using biofuel/bioplastic instead of fossil fuel; zero waste etc.

What the Judges Thought

This is an important and large research project on hemp production. It showed clear research outcomes and good engagement with external stakeholders. 

What it Means to Win

"Commitment to sustainability is key to our Aberdeen 2040 strategy. This Green Gown Award for Research with Impact is testament to the outstanding work of colleagues to engage others and enable beneficial change. This achievement recognises how our research is advancing sustainability and addressing the UN’s Sustainable Development Goals."

Top 3 Learnings

1. Hemp is rich in dietary protein, fibre, and omega 3, providing health benefits, and reducing hunger.
2. Hemp brings a low carbon environmentally responsible “cash crop” to Scottish agriculture.
3. Creating a network of supply chain stakeholders was key to regenerating the hemp food industry.
