Overview
ABSTRACT
Composting is a valorization process for domestic, industrial or agricultural waste. This biological technique for the transformation of matter is composed of two phases: a relatively rapid aerobic fermentation followed by the maturation of the compost for a few months. An optimal treatment requires a true scientific and technological approach as well as the perfect mastery of the main operating parameters. This article deals with all these notions. It starts by presenting the principles of composting, in particular the issue of gaseous flow and odors as well as the means available in order to limit the discomfort caused by these gaseous emissions. It then deals with the various treatment processes. To conclude, a practical case from the industry is presented in order to explain the method to be applied.

INTRODUCTION
The composting of organic byproducts from domestic, industrial, or agricultural sources is growing rapidly. Indeed, this method of material recovery is fully in line with the principles of sustainable development, as the production of an organic soil amendment from waste represents an attractive technical and economic alternative to energy recovery (incineration with heat recovery, anaerobic digestion, gasification, etc.) . However, the...
