Sustainable odour control in urban environments


With an ever increasing focus on sustainability, the municipal recycling sector is increasingly locating recycling facilities in urban environments to be closer to their waste sources.

The odour control industry needs to respond in providing ever more efficient odour extraction technologies to minimise any odour nuisance to their residential community neighbours.

In addition, cost pressures (and social responsibility) drive the development and design of more energy efficient odour control systems for reduced carbon footprint.

This paper reviews some of the new design approaches and innovative technologies available, many of which ERG have employed in some recent installations.

Odour control technologies for the waste water and sewage sludge treatment sector are becoming increasingly based on established and proven technology. Abating the odorous discharges from even the most odorous sewage sludge secondary processes is now relatively straightforward. These established and proven solutions, however, often come at a heavy cost in terms of carbon footprint, particularly in urban environments where maximum odour discharge limits are now specified at levels which were considered unachievable even 10 years ago.

The municipal sector, with its new determination to recycle household waste, now faces the challenge of recycling waste in a sustainable fashion. Odour control for these recycling facilities is a significant operating cost as the odour control systems required to abate these new facilities have large carbon footprints.

This presentation will present some of the challenges facing odour control designer for these types of facilities.
