“Buy rice hulls. California has a surplus ad they are better for the animals less problems with bugs and infection.”
A good idea for certain uses on the farms. But rice hulls contain large quantities of silicon ... not appropriate for a replacement of sawdust in industrial uses.
Yes would not work well in particle boards but will help the farmers. South Dakota pig farmers buy tons of it and there are many more tons in the Gold Valley.
Also I hear there is an entrepenuer up tha way working on a way to solve the silcon issue for particle board, something called MDF.
