Abstract :

Background and objective: CIE color standard system has been extensively used to determinevarious physic-chemical characteristics of porous media such as soil. Objective of this study is toevaluate the relationship of C/N ratio and organic matter percentage with parameters of CIELAB colorstandard system during composting production process.Material and methods: In this study, changes on parameters of CIELAB color standard alongsidewith organic matter percentages and values of C/N ratio were measured for 90 days during urban solidwastes materials’ composting process in Arad-Kouh factory in Tehran.Results: The results showed that there are significant relationships of L* with organic matter(r=0.942, α=0.01) and ratio of C/N (r=0.915, α=0.01) from one hand and parameter of a*/b* withorganic matter (r=-0.876, α=0.01) and ratio of C/N (r=-0.893, α=0.01) from other hand.Conclusion: Statistical interpretation of the obtained results approved that instead of commonanalytical methods for quality evaluation of composted materials; parameters of L* and a*/b* areeasy, inexpensive and quick to estimate ratio of C/N and organic matter percentage of compostedurban solid wastes materials reliably.
