am very pleased with my insulation baking kitchen for a future project

In my location , nearby i can get high quality clay from a quarry for 11 euro a ton and straw or barley skins ( do not know the English word .... husk ? ) that i can source for 7 euro per m3
from left to right first is straw and clay , next is husk and clay , next is husk clay and coconut fibers , next is just sand clay and coconut fibers
The coconut was just because i tie trees with it but hemp should work too or horse, pig hair human hair from the hair dresser , as an reinforcement
All of those where worth the cooking and are super solid with different weight .... I was told that eco friendly insulation or even oil based insulation is costing in the region of at least 200 Euro per m3 .... so that should cost about 20
Not ony because of costs .... good to be a child too

I like clay as an material and prefer it to cement , lime or oil based , as not much enrgey enbodied
Just a thought
