چکیده

Purpose Green waste (GW) composting is of increasing importance to the waste management industry in addition being a useful agricultural product that is rich in nutrient and organic matter (OM). The combination of aerated static windrow with GORE(^R) cover membrane and an air-floor aeration system is a relatively new industrial-scale composting technology that has not been previously explored. Therefore, the aim of this research study was to evaluate the effectiveness of composting GW using this new technology.
Method The composting process was monitored through changes in the physico-chemical properties, E4/6, and fourier transform infrared (FTIR) spectra.
Results Disinfection requirements were met by holding composting temperature steady in the thermophilic range for 24 days. The technology greatly improved composting conditions, and final compost product in terms of temperature, pH, electrical conductivity (EC), C/N ratio, OM degradation, nitrogen transformation, humification, and cation exchange capacity (CEC). The FTIR spectra revealed that there was enrichment of aromatic compounds and reduction in aliphatic structures and easily assimilated peptide components by microorganisms, indicating the humification degree increased, the final compost stabilized, and confirming the efficiency of composting. Consequently, the new technology produced a mature compost in only 30 days compared with the standard period of 90–270 days for traditional composting.
Conclusion Notably, the new technology may be a sustainable alternative for GW management that converts waste into compost and could be beneficial for agricultural uses.
