I'm new here but enjoy all of the information I'm reading. We're about to purchase 2 Loveable Loo bucket toilet systems for our 4 bathroom house (yes, we're modern, suburban folks trying to go "off-grid" or at least straddle the grid!). Anyway, I can't find sawdust anywhere... and if I can't find sawdust, then I'm hesitant about investing time, money, effort into the bucket toilet system. Where does everyone get their sawdust from? How much is it? Are there good alternatives to sawdust if it's not available? Thanks!
