CEO AND FOUNDER OF HEMSPAN

Hemp has a wide range of properties and uses , providing the construction sector with a low cost , sustainable and high performing alternative . One hectare of hemp sequesters nine to 15 tonnes of CO 2 , similar to the amount sequestered by a 15 – 20 year old forest , but it only takes four months to grow .

What are the potential impacts of widespread adoption of bio-materials for the construction industry and the environment as a whole ?

The construction industry is responsible for nearly 40 % of global carbon emissions . The widespread adoption of bio-materials in construction could revolutionise the industry and significantly improve its environmental impact . It would drive innovation in the sector , transform supply chains , and shift skill requirements , while substantially reducing carbon emissions , sequestering carbon , supporting biodiversity , and reducing waste .

As extreme climate events continue , our houses and buildings are struggling to adapt . This is a particular issue in the UK as many of our buildings are old , and damp and mould are frequently reported . By using bio-based materials in construction , it can enhance building energy efficiency and offer occupants a more sustainable , healthier living space .

Furthermore , it could create new industries and job opportunities . The UK ’ s green economy is four times larger than the manufacturing sector , yet the government is behind on their pledge to deliver 2 million jobs in this area by 2030 . Investment and innovation in the green sector is sorely needed , and construction can play a significant part of this . Increasing investment will not only boost productivity and jobs , particularly in rural areas where hemp can be cultivated .

How can bio-materials like hemp interact with modern construction technologies ?

Hemp should not be viewed as a replacement for all modern materials , but as a complementary component that can enhance the overall sustainability and performance of building systems .

Hemp insulation and hemp fibreboard can be incorporated into automated building envelope systems , enhancing energy efficiency and providing natural moisture regulation . When combined with smart home technologies , hemp materials can improve indoor environmental quality .

Additionally , hemp-based composites are being developed that could potentially replace carbon-intensive materials in 3D-printed construction projects , merging cutting-edge additive manufacturing with sustainable bio-based inputs .

How does this relationship between technology and bio-materials benefit the end-users of these buildings ?

Using technology and bio-materials , like hemp , creates buildings that are not just structures , but intelligent , living systems that actively contribute to the health , comfort , and well-being of their occupants , while minimising environmental impact .

Bio-materials can provide occupants and residents healthier , more energy-efficient living environments , improving comfort and helping to lower energy bills . These materials also improve indoor air quality by being non-toxic and regulating humidity levels . The integration of smart technologies with bio-materials can further optimise building performance , leading to more sustainable , cost-effective and enjoyable spaces for occupants .

What are the primary challenges faced when integrating bio-materials with current construction technologies , and how can these challenges be overcome ?

Integrating hemp with current construction technologies presents several challenges . But it also provides opportunities for innovation .
