It costs me about 2 pence to flush a toilet. For the 2 of
us, at the most that would be 15 pence per day or about £55 per year in water
use. However as we do some dumping
elsewhere in practice it is less than that.

Now where do I get and transport and store enough sawdust at
what cost to make this a green and viable proposition. I garden and grow vegetables and have done a
fair bit of composting. It is not as easy
as suggested to get a compost heap to function effectively at all times and for
most people to get one working at a temperature to ensure all human pathogens
are killed just won’t happen. In addition
some mug i.e. me will have to move this shit bucket for composting. One slip up
and you have uncomposted shit somewhere you don’t want it that someone has to
clear up. Then I have to get straw to cover this up. Which has to be purchased and transported and stored.

Just moving and cleaning the bucket once per week will take
about 30 mins that even at minimum wage is about £150 per year. So this is neither
practical nor economic. I think a grey
water solution is a better bet.
