Morocco is one of the major olive-producing countries with an annual production of
1.56 million tonnes, part of which is dedicated to olive oil production. This important production
generates, in addition to oil as the main product, a significant amount of waste (pomace and olive
mill wastewater). The latter, when released in large quantities into the natural environment, cause
fatal pollution. A suitable valuation of this waste will allow a clean and sustainable production
for the sector. This work consists of composting olive pomace from the traditional system with
two structural agents (poultry droppings and cattle manure) and comparing the two composts in
terms of composting process parameters (pH, electrical conductivity, organic matter temperature,
etc.), organic matter dynamics and compost quality, with manual aeration of the compost. Despite
the high humidity level of the used pomace (80%), the adopted composting conditions have been
effective in reducing high levels of organic matter and therefore organic carbon, as well as
reducing the extreme phytotoxicity of the pomace. The experiment showed that the stabilization
process in all the four treatments studied is comparable, and the final quality of the composts was
adequate for agricultural use.
