Interest in fibre hemp is growing steadily, mainly because of the valuable role it can play as a biobased building material. Building Balance, in collaboration with farmers, researchers and processors, has examined the developments and cultivation results of 2023 and 2024. The findings shed new light on the possibilities and challenges for hemp cultivation in the Netherlands.
Hemp fibres are a promising raw material for insulation materials and other biobased building products. In addition to the ecological benefits, research shows that hemp cultivation also has a positive effect on the soil. The plant's deep roots improve soil structure and water management, making the crop a valuable addition to sustainable agricultural systems.
Scaling to multiple regions
While in 2023 mainly growers from the Stedendriehoek region experimented with hemp cultivation, the working area has expanded considerably in 2024. Farmers in Salland, the Achterhoek, Twente, Brabant, Limburg and the Gelderse Vallei have also ventured into cultivation. This regional spread offers interesting insights: while the first results are encouraging, it appears that soil conditions and weather conditions require customization per region for a successful harvest.
Weather and fertilization as crucial factors
Although hemp is considered a relatively robust crop, there are important factors that influence yield and fiber quality. The research shows that extreme weather conditions – both wet and dry periods – leave their mark. In addition, fertilization plays a decisive role: an imbalance in nutrients can significantly reduce fiber quality. The moment of sowing and harvesting also appears to be essential for optimal yield.
From cultivation to a profitable product
To successfully integrate hemp into the construction sector, not only the cultivation must be in order, but also the processing and sales. Collaborations with companies such as Exie, Dun-Agro, Hempflax and GreenInclusive show that the market has potential. However, further professionalization of the chain is necessary to ensure stability. This requires investments in infrastructure, processing capacity and market development.
Knowledge sharing as the key to success
This report, drawn up by Building Balance in collaboration with Wageningen University & Research, bundles insights from various growers and chain partners. By exchanging experiences and sharing the knowledge gained widely, entrepreneurs and policymakers are given tools to further professionalize hemp cultivation.
