Abstract

   Nowadays, the increase of waste treatment plants based on biological treatment processes involve different kinds of gaseous emissions, from those known as Greenhouse Gases (GHG) to organic and inorganic volatile compounds. The latter are also related to the odorous impact produced by a determined process or installation.

   The present work is part of a project in which different types of waste treatment plants, either solid wastes or urban wastewater, are evaluated with the aim of relating their characteristic gaseous emissions –total volatile organic compounds (VOCs), NH3, H2S and GHG– with each kind of process. Particularly, a case study about the emission of VOCs and NH3 in a sewage sludge composting plant with odour problems is presented.

   The composting process is divided in two phases, first an active composting phase in dynamic windrows and then a curing phase. The evolution of both processes was evaluated by means of temperature and humidity measurements of the solid material as well as the waste stability –Dynamic Respiration Index (DRI)– and gaseous emissions. It was observed that increasing the materials residence time in the windrows leads to a better waste stabilization –from DRI=0.96 g O2·kg MS-1·day-1 to DRI=0.48 g O2·kg MS-1·day-1–. The VOCs and NH3 measurements showed a decrease of the gaseous emissions generated in the curing phase –from 23.68 g NH3·Mg treated material-1·day-1 to 0.81 g NH3·Mg treated material-1·day-1 and from 3.02 g VOCs·Mg treated material -1·day-1 to 0.00 g VOCs·Mg treated material-1·day-1–.
