Rubisco expands hemp processing capacity with new Ashburton facility
Original article by Annette Scott, published 3 November 2025 — “Rubisco scales up hemp capability”
As global demand for low-carbon, plant-based materials accelerates, New Zealand company Rubisco is taking a major step to scale up its hemp fibre operations, relocating its hemp decortication facility from Christchurch to a new, purpose-built site in Ashburton.
The move, originally reported by Annette Scott (3 November 2025), reflects both market momentum and Rubisco’s commitment to sustainability and operational efficiency.
A strategic shift to meet rising demand
Rubisco, a leader in natural fibre extraction and sustainable material systems, has seen rapid growth in its hemp division thanks to increasing demand from the construction, textiles, and biocomposite sectors. Its vertically integrated model — from supply chain to fibre blending — positions the company to deliver high-performance materials with a markedly low carbon footprint.
According to CEO Guy Wills, the Christchurch facility had simply reached capacity. The new Ashburton site will allow Rubisco to scale production while improving logistics.
Why Ashburton?
At the core of Rubisco’s operations is hemp decortication — the mechanical process that separates bast fibre from woody hurd. These materials are essential to a wide spectrum of industries, including hempcrete construction, insulation, textiles, bio-composites, and specialty products.
Relocating the decortication line to Ashburton brings Rubisco closer to its primary fibre-growing base, enabling:
- Reduced transport emissions
- A streamlined supply chain
- Room for expanded value-add processing at the Christchurch site
- Increased production capacity to meet global demand
Wills describes the shift as “both practical and forward-thinking,” adding that the new facility will support research, innovation, and stronger engagement with local growers.
Hemp’s role in the low-carbon future
International markets continue to turn to hemp for its versatility, strength, and environmental performance. Both fibre and hurd can be engineered into products that support decarbonisation — from high-performance building materials to advanced textiles and bio-based plastics.
Rubisco’s expansion aligns with the hemp building industry’s trajectory across Australasia: growing supply, greater industrial capability, and increasing recognition of hemp as a cornerstone renewable material.
The Ashburton facility is expected to be fully operational in early 2026.
