Purpose: This work was aimed to exploit the technique of design of experiments to evaluate the olive mill waste cake residue obtained after oil extraction while searching for an adequate composition of the initial substrate mixtures (RPM, DMOV, FV and EB for humidification), in addition to validate it experimentally. Method: To this end, a mixture design using an efficient experiment methodology was constructed, with the aim of optimizing three responses of interest: pH, humidity, and organic matter of the 25 formulations. Results: The optimal composition was comprised of organic and green household waste (56.7%), olive mill waste cake residues (21.7%) and poultry droppings (21.7%). These analyses were followed by the evolution of some physio-chemical parameters such as pH, temperature, organic matter, C/N ratio and polyphenols until they are stabilized. In addition, using spectroscopic analysis, maturation and phytotoxicity tests were carried out on the germinating cress. Conclusion: The results of this research indicated the achievement of an ideal composition of an adequate mixture that had the characteristics of an organic amendment, non-phytotoxic and in conformity with the NFU-44-051 that led to mature compost. | ||
