yoshiro makes a compost toilet based on the 'humanure handbook'
using local waste products . these are 'kanbatsu-zai' - the trees deemed unsuitable for milling and cut down to allow the other trees to achieve full potential . the trees are japanese cedar , a beautiful wood very common in japanese building
luckily we have yoshiro the human bulldozer
and mighty mike
and the hardworking local ladies .
putting in the foundations for the composting system .
what a team !
nearly finsihed . the system will compost all the toilet contents and cafe waste . thats why it is so substantial ( huge ! ) . basically the left and right hand bays are used alternately - when one is full the other gets used , giving the first one time to compost thoroughly . the centre bay , with the roof is used to store carbon ( in our case straw and sawdust ) to soak up the nitrogen rich wastes . good compost is a ratio of 30parts carbon to 1 part nitrogen .
more details can be found about this system here 'humanure handbook'
more about composting details from the permaculture master Geoff .. compost
