Composting is considered as the most promising technique for the valorisation of these products. In this work, the heap composting way is evaluated. Several physicochemical （pH, humidity, salinity, density, organic matter rate, C/N ratio, heavy metals） and some microbiological parameters （total and faecal coliforms, Escherichia coli, streptococci and salmonella） are studied after compost maturation. Main results show that palm compost is characterised by a neutral pH （7.87）, low humidity （40.77%）, high organic matter （50%）, high salinity （2.06 g/L）, acceptable C/N ratio （12.2）, low density （0.43 g/cm3）, high conductivity （3.22 ms/cm）, 109.6 ppm of NH4 and 256.66 ppm of HNO3. Finally, microbiological parameters respect hygiene requirements in comparison with compost quality standards.展开更多
