sawdust dumpstering

About once every six months, I make a trip out to the wood shop dumpster to get sawdust for my compost toilet system. I checked with the shop in advance to see that they don't use any treated wood and asked permission to stop by and fill up on sawdust. Of course it benefits them since I'm lightening their waste load and I get free material to process my cat litter and compost toilet. Videos coming soon...
