During 2018, Chile began to generate quality standards for offensive odors. The priority of the authority was defined by type of activity and the historical number of complaints per year raised by citizens for every type of industry. From the analysis, five industries were selected for the first stage, among which the Chilean Kraft pulp industry was part of, activity representing approximately 2% of world production.

   Facing complaints, the lack of development planning and land use, the absence of quality standards the null international and bibliographic experience of how to proceed with odor management in this type of industry contributed to creating the necessary need to generate online, integrated, prompt response tools that could allow the odor impact to be managed efficiently in real time.

   Since this month November 2022, GRAL dispersion model presents a new website: https://gral.tugraz.at/ The Graz Lagrangian Model - GRAL - was initially developed in 1999 at the Institute of Thermodynamics and Sustainable Propulsion Systems at Graz University of Technology.

   In addition, new features and bugfixes have been implemented in the new GRAL Version 22.09, which is now available on the GRAL homepage.
