TLDR
A literature review of the main start-up, monitoring and maturity parameters are discussed in this article concerning different raw materials used and different composting methods practiced, and the wide variety of chemical and biological variations that occur during composting has made it difficult to agree on methods for the practical assessment of maturity.Abstract:
Economic growth and rising food consumption in the world have led to increased production of organic wastes due to an important intensification of the agricultural production systems. The analysis of macro elements (nitrogen [N], phosphorus [P], and potassium [K]) in organic wastes reveals that the economic loss is significant with the intensification of the agricultural system. The good management of those wastes would be an effective means of organic matter restoration through carbon restitution to the depleted soils through organic amendments. Composting is a type of waste processing that has gained increasing acceptance over the years. As a rule, the process consists of the natural biological decomposition of organic waste components and involves diverse species of microorganisms. Those organic residues could reconstitute soils and be an important fertilization backup. Composts prepared from different organic wastes differ in their quality and stability, which further depends upon the composition of raw material used for the compost production. Compost quality is closely related to its stability and maturity. The wide variety of chemical and biological variations that occur during composting, and the range of methods suggested in literature, has made it difficult to agree on methods for the practical assessment of maturity. A literature review of the main start-up, monitoring and maturity parameters are discussed concerning different raw materials used and different composting methods practiced.read more

Nitrogen transformation during organic waste composting by the Rutgers system and its effects on pH, EC and maturity of the composting mixtures
TL;DR: The ratio of NH4-N and NO3-N concentrations was shown to be a clear indicator of the maturity of the mixtures during composting, the final values of 0.11 for the four mixtures being equal to, or below the maximum value established as a maturity index in other materials.
