Our work shows that humified organic matter can be prepared
with OMW as major component using a novel static composting
process conducted in gas-permeable bags. The use of bags
permitted to carry out a satisfactory aerobic static composting
without performing any artificial aeration and periodic watering of
OMW mixture. In terms of the main chemical physical parameter
changes of compost, the innovative system showed to be comparable
to conventional composting procedures and led to the preparation
of stable and mature compost, satisfying the standard
requirements set by regulators.
