[Cob] Paper cob...

[Joseph R Dupont]

I have made blocks of paper      pulp and soil and made some very nice
looking blocks .. very strong.
The only issue I see is the water absorbtion of paper vs. straw. Straw is
hollow and does not neccessarly
suck up water .. Paper does.  I would put a layer of clay on th e 
outside of the unit to keep the water
from suck in in. 
I just put a coating of kitty litter and paper pulp on an inside basement
cinder block wall.
It looks really nice I like the concept.
