GAroca   The processing of meat by-products for the production of protein meals entails the generation of gaseous emissions causing annoying odours that cause a severe environmental impact in the surrounding populations.

   This work presents the characterization of the main components of the process emissions, the dimensioning of the treatment system and the results of the operation of a rendering plant of turkeys, where fractions, such as viscera, blood, feathers, as well as seizures and discards, are processed to produce flour and oil for animal feed. This plant has a processing capacity of 8 million turkeys per year and a projection of 12 million.

Abstract

   The processing of meat by-products for the production of protein meals entails the generation of gaseous emissions causing annoying odours that cause a severe environmental impact in the surrounding populations.

   Sopraval SA is a producer and marketer of turkeys for national consumption and export, located in Nogales, Region of Valparaíso, Chile, with a processing capacity of 8 million turkeys per year and a projection of 12 million. In the rendering plant, the non-edible turkey fractions, such as viscera, blood, feathers, as well as seizures and discards, are processed to produce flour and oil for animal feed.

   This work presents the characterization of the main components of the process emissions, the dimensioning of the treatment system and the results of its operation.

   The system consists of a stage of physical treatment, using condensers and filters, a chemical stage of two chemical scrubbers and a biological stage; a biofilter. The system has operated for a year and has reached 100% removal of the main responsible for the odour nuisance caused by the operation of the rendering plant.

What are cookies?

   A cookie is a text file stored in a user’s web browser on any device they use to access a website that holds information regarding the user’s visit, such as preferences. When the user returns, the browser provides the cookie with the stored information to the site.

What cookies are used for?

   Cookies are used for adjusting a website’s content to fit a user’s preferences and optimize the website. They store useful information that improve the user’s experience of a website. They are most commonly used for:

  •     Creating statistics that help website owners to understand how their users interact with their website, which allows them to improve their structure and content.

What types of cookies are used?

Persistent cookies remain on your hard drive for a period of time specified in the cookie’s file parameters or until removed manually. When you return to a website and it requires you to login again despite previously storing your login information, it is usually because the persistent cookie expired; this helps to increase security while maintaining accessibility.

When a website requires that you verify your age or location once every visit before allowing you to view content and without requiring additional personal details, that is a session cookie at work.
