Gaseous emissions and air treatment in composting

This approach to treating gaseous effluents generated during waste composting has made it possible to define:

• the methods for oxygenating the windrows based on the processes used. Air injection is preferred because it provides uniform aeration of the fermenting material;

• the ventilation of the various zones within the composting plant, which must be compartmentalized: raw material storage, aerobic fermentation, and compost maturation;

• the treatment processes for the extracted air. Biological systems appear to be best suited to the flow rates and quality of the gaseous effluents to be treated.

An industrial example was presented by applying the steps outlined in a previously established set of specifications. The outlined approach was implemented to set up the compartmentalization and extraction system. Air treatment consists...
