LCA study of flax and hemp products

To support the manufacturers of flax and hemp based building materials, Grow2Build made LCA studies of some products. These LCA's show what the high impacts are for the different raw materials, energy and transport. With this information, the manufacturers can adjust the production process and make their product even more sustainable.

To know more about the total production process, LCA's of the cultivation and the process of flax shives and fibers is done.

Following LCA's are made, but they are because of confidentiality reasons only accessible after approval of the manufacturer.

31/03/2015 Meeting on bio based building and health @ Applied Plant Research, Valthermond (NL)

People spend an increasing proportion of their lives indoors. March 31st 2015 an open brainstorming session with an interdisciplinary team was organised on health aspects of bio based building. The session was focused on (1) Sharing knowledge and identification of knowledge gaps in the field of bio based building and health; (2) formulation of a road map with suggestions to fill knowledge gaps; (3) ideas for communicating the established health benefits of bio based building materials.
Via the author also the full results, with all answers collected during the GDR session, are available in a report in Dutch.
Report of the session

Final report Health, comfort, energy use and sustainability issues related to the use of biobased building materials
