Sanitary landfill odor control experience using organic biocatalysts and field olfactometry measurement

on .

Quintero   The sanitary landfill, located in the city of Pereira, Risaralda, Colombia, is operated by the company Atesa de Occidente S.A ESP, here the disposal of waste from department of Risaralda, some municipalities of Caldas and Norte del Valle del Cauda is carried out, it´s receiving 800 Tons/day, causing impacts to the environment by the emission of offensive gases and odors, causing problems to community.

Analysis of odour episodes through dispersion modelling, field olfactometry and citizens’ complaints near a paper-mill

on .

Valdenebro   The RAMS-CALMET-CALPUFF modelling system has been used to simulate the odorous impacts from a paper-mill in an urban area located several kilometres away in a coastal mountainous area.

   Over the last years, episodes of citizens complaints due to malodours have been registered, with a potential origin in several pollution sources located inside and outside the city. A selection of episodes under anticyclonic conditions, with poor ventilation in general and continuous changes of stability and wind during the day, has been simulated.
