The farmer starts the product chain of the hemp or flax based building products. Grow2build intended to stimulate and support farmers to grow hemp and flax. To create a decent market it will be necessary to grow crops with good technical qualities. Different field pilots have been carried out to find out which crops, soils and conditions are best suited. Results of those pilots can be found below. An open innovation network has been set up so different target groups could meet each other and exchange information.
Unretted flax straw ready to be send from Inagro to Saxion.
Saxion will use this straw for the research pilot ‘Ten Cate’.

2015 - Evaluation of the retting process on different species of flax
Report on flax's retting - Materia Nova
Presentation of the improvement made at Materia Nova on flax retting (2 processes, 1 upscaling, 5 different flax species tested)
Report on enzymetic retting of flax - Materia nova
Two processes for the enzymatic retting of flax were evaluated. The process with wet incubation of flax bundles was found to be more suitable for reliable retting. Moreover, it was found to be independent from stirring and adaptable to the external temperature.
Crop fact sheets
The fact sheets contain information about the cultivation of flax and hemp to insure a fibre quality which is optimal for building applications. The information has been compiled by carrying out field tests on different locations and with different weather and soil conditions.
