Treatment of emissions generating annoying odours in a turkey by-products processing plant

on .

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.

Biogas treatment with recovery of nutrients from centrate in an outdoors high rate algal pond through algae-bacteria systems

on .

D_Marin   The upgrading of biogas coupled with centrate treatment was evaluated in an outdoors photobioreactor interconnected to an absorption column of CO2 and H2S from September to December 2016.

   The maximum recorded CH4 concentration in the biomethane was 94%, with total removal of H2S and removal efficiencies of CO2 ranging from 70% to 90% depending on the environmental conditions.

Estimation of stable-run time for Biofilter to mitigate environment pollution due to Styrene emission and other VOCs from Reinforcing Plastics industry

on .

reinforced fiberglass   The Fiber Glass Reinforcing Plastic Industry in Argentina has undergone a huge development. Unfortunately, only a few facilities work with appropriate abatement pollutant emission technology. That is so due to the lack of regulations and control laws in this country.

   This work describes a case study of the design of equipment to reduce styrene emissions from a filament winding and chop hoop mixed process from a factory that produces Reinforcing Plastic pipes.
