Do odour impact criteria of different jurisdictions ensure analogous separation distances for an equivalent level of protection?

le .

oic separation distances   A very interesting and open access paper will be published this month in the Journal of Environmental Management. This paper is signed by the well-known experts Marlon Brancher, Martin Piringer, Andreas F.Grauer and Günther Schauberger and deals with the interesting topic of setting up separation distances to avoid odour impacts.

   This study shows that the use of different odour impact criteria (OIC) produces different separation distances between odour sources and residential areas for an equivalent level of protection.

Final version of GRAL 20.01 released and now it is open source!

le .

gramm gral 20.01   The Graz Lagrangian (GRAL) system is a Lagrangian particle model with a free Graphic User Interface (GUI) available in both Linux and Windows. The last beta was published last November and now the developers have released the version 20.01. The software is now open source under a GPL-3.0 license, so everybody is welcomed to contribute to the project. The source code, has been published in github.

    The Graz Lagrangian Model - GRAL - was initially developed in 1999, and has been used extensively in regulatory assessments and scientific studies. The initial driver for the development of GRAL was the need for a model that could deal with the frequent low-wind-speed conditions (< 1.5 m s-1 for up to 90 per cent of the time) in the inner-Alpine basins of Austria. According to the developers, there are around 600 users worldwide using, the GRAL/GRAMM system.

How to determine the sources of bad odours? Benefits of operational control for environmental risk in the industry through Predictive Digital Platform

le .

A Harreveld   Currently, odour modelling maps represent a static photo on the impact assessment in P98, 1h. This information allows the proper design of odour control measures, regarding emission reduction or better dispersion. However, this information is not enough to carry out an operational and proactive odour management, which is associated with the operations at installations.

   A digital platform like EnviroSuite is a technological product which provides a comprehensive solution, able to manage environmental risks in real and predictive time. The main objective of this platform is to improve operational efficiency in the industry, through business planning and environmental compliance approach.
