Peter,
If your sawdust has a low moisture content (say around 15%), I would use 1.2 litres of LOF for each kilogram of sawdust. I don't know what an optimum time would be. With turning daily you may only need 5 to 7 days. Around 21 days might be needed. Commercial compost systems are required to let the heap stand for at least 42 days before being used (i.e sold to the public). A composting toilet using sawdust as an absorbant may take 2 to 3 years to process. Stable manure with sawdust takes three years to break down to the highest quality compost but is usable at a lower quality after one and two years.

Hi Kim ; LOF is Liquid Organic Fertilizer or what Keith calls Household Compost Activator, in other words, urine. Yes I guess I could put in some grass or leaves, which is what most recipies call for. But two problems with that. One is I live in a concrete village. There is no grass or trees anywhere. That is no exageration. I don't have a front yard or back yard. Just concrete everywhere. Nobody around here ever has grass to cut, so I can't just pick up someone elses cuttings either. In order to get some grass I would need to get in my truck, drive a kilometers, stop on some else'e property and start cutting away. Lot's of free sawdust fines though. Secondly, for my project in the near future, I will have LOT's of wood after the hammer mill but not so much greens. This is more a learning excersize. So I'm just investigating the possiblities of no grass, ONLY sawdust and LOF. The wood is carbon, and the LOF is the nitrogen, and it should be possible if I can keep it aerated. Is it? What ratio? Truthfully, there are also a few small table scraps, but very little. I live with my daughter and there is normally only a watermelon or orange peel per day. Let's ignore that for the time being. If this doesn't work, I will go grass cutting, but please humor me first. It should be possible with just sawdust and LOF. Is it? What ratio? How much time? Is strong ammonia smell normal? Is very little heat normal (I think not)? Once I get a formula and procedure that looks correct, I will do a 55 gallon drum. Already got the drum. Best Regards, Peter G.
