Sawdust

I started this thread as a gardening question, now it seems I need an explosive licence from the council!  I use sawdust on the footpaths. I also mix urine into the sawdust as a nitrogen additive. I am due to have a water meter and I was wondering about the collection aspect. Store it in milk containers. Seems to work OK.

We used to keep our sawdust in huge poly barrels with lids, then use the dust as needed.
