In industrialized cities, there are many possible sources of odorous compounds, such as steel and pelletizing industries, wastewater treatment plants, landfills, and harbors. For most of these sources, limited data is available on odours emissions in inventories. To estimate odorous VOCs in gaseous emissions from industries it is necessary to identify which VOCs are emitted and are odorous.

   Although reasonably simple, there are few papers addressing this issue. Thus, this study aimed to categorize chemically the VOCs and TRS emissions from major activities in an industrialized urban area of Brazil, crossing references with U.S. EPA - AP 42 documents, SPECIATE 4.5 database, and literature available.

   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.

   Biogas is a very interesting source of renewable energy. However, its desulfurization is necessary, and sometimes an adjustment of the methane (CH4) concentration (upgrading), by reducing the carbon dioxide (CO2) concentration. The removal or capture of CO2 can be carried out by biological methods, with microalgae being the most used microorganisms, given their high CO2 assimilation capacity.

   However, high CO2 concentrations inhibit the microalgae growth, which makes it difficult to apply. In the present study, a microalgae consortium of leachate from landfills has been isolated to study the effect of CO2 concentration on its growth. Two bubble column photobioreactors were built with an inner diameter of 100 mm and a working volume of 8 L.
