Eco-FriendlyHousing should be defined first so we are on the same page and talking about the same thing. Let us look at this from an ideal point of view embracing multiple aspects and not just one in particular. Eco-friendly homes are made up of organic or recycled materials to lessen damage to the environment.
Kenafcrete can then be considered Eco Material. Building with kenafcrete needs to be practical, which includes affordability and superior benefits in the material as well as construction time and costs. Building standards need to be met with certified testing, engineering specifications applied to design / build projects at multiple locations. Each of these points are shown here: Affordable Homes by Tim Tan .
You do not have to be a rocket scientist to build with kenafcrete. Easy to learn on the job training, manufacturing prefabricated walls or kenafcrete blocks. Installing the prefabricated walls and bricks. This can be seen by watching the following 3 short videos.
Kenafcrete is made with kenaf wood core chips, hydrated lime and water. The fundamentals of building with kenaf are centered around a simple “4: 1: 1 formula ” - 4 parts kenaf wood core , 1 part hydrated lime and 1 part water. A finishing lime plaster is then applied to seal the walls, which protects the walls from heavy moisture and still allows the walls to breathe.
Kenafcrete sealer is made with slaked lime and water called a lime plaster. It is available at places like Home Depot and Tractor Supply throughout the US.

The hand tools in manufacturing and installation are readily available around the world.
Equipment for kenafcrete manufacturing and installation are top rotary mixers and specialized sprayers.
Replacing 2X4s, 2X6s etc. in stick built homes with bamboo can go a long way in preserving our forests and the eco-system they support. Introducing bamboo in strategic locations that are beneficial to the environment and a good use of existing land and using bamboo instead of lumber is an obvious next step in the alignment of regenerative housing and regenerative farming. An example of how this might work is to take a corn / soy field in central Illinois and instead of drain tiles and drainage ditches, use a key-line plow to address water retention for drought flooding. Drainage ditches converted to grow bamboo
Kenafcrete is a biocomposite made of the inner woody core of the kenaf plant mixed with a lime-based binder. ... Fully cured kenafcrete blocks float in a bucket of water. It is not used as a structural element, only as an insulating infill between the frame members though it does tend to reduce racking. Racking is the term used for when buildings tilt as their structural components are forced out of plumb.... To be able to resist the forces of high winds and safeguard against racking , a continuous load path is a construction method that secures a building from the roof to the foundation.
Here in northern Michigan deer blinds and ice fishing shanties made from bamboo and kenafcrete could catch on as a specialized housing use and make the list of eco-friendlyhousing.
